grblHAL build/patch 20250114.
Driver: RP2040 (Pi Pico & Pi Pico W)
Board : BTT SKR Pico 1.0
Native USB or virtual 3 axes: No Work. Alarm $X error 79. No way to unlock.
Native USB or virtual 4 axes: run like a charm with 4 axes. $X unlock is available.
So using 4 instead 3 but don't now why..
release 20240228 was running well in 3 axis but new version give a problem on 3 axis:
no way to unlock, as well as on Pico or PicoW.

[terjeio]

Native USB or virtual 3 axes: No Work. Alarm $X error 79. No way to unlock.

$14 cannot be used to invert the estop input?

[terjeio]

Should be fixed now.

grblHAL/RP2040#109

mdns not build

[TPMoyer]

Terje:
Yes I understand this is off topic, but am unaware of another way to contact you.
I made a mistake and deleted the "Additional or extended settings" page from the core/wiki
Please restore the page.

Had opened an edit to point to a new page enumerating the outputs from $help and the several $help topic   commands.     

Got stuck in the edit, and bailed by pushing the delete page button.
This deleted the original page, not just the incorrectly modified page.
Ohhhhh crap.

[terjeio]

Restored now.

Was trying to build a new firmware with the web builder because I am strugling with #653 and #634 too when building with pio under windows.
But currently the build process for ESP32 boards is not working.
I have tried several times with different settings and different boards for ESP, but I always get the error: message Build failed: 504

[terjeio]

Try again now, I have been meddling with the Web Builder code (I do not have a test server yet).
If still fails the which board are you compiling for?

[dddidi]

Thank you for your quick response.
I am trying to build for the "MKS Tinybee V1.0"
For the test I did not set any parameters just selected the board and pressed generate.
But the build failed again (Build failed: 504)

[terjeio]

Builds for me. Did you reload the page (I forgot to mention that).

[dddidi]

OK. Reload of the Page did the trick.
Thank you very much for your help.
I was able to download the firmware.

[euridium]

i am trying to build for picobob_dlx. 4 axis with networking.
the reset pin is not mapped as you would expexct (gpio 3), as its state isn't changed by the estop input on a mach3 BOB.
when i compile the picobob non delux - the pin is proppery mapped and it works.

looking at the board profiles i suspect it is to do with this section :

// Define user-control controls (cycle start, reset, feed hold) input pins. Only Estop is supported on the Mach3 BOB.
#ifndef I2C_STROBE_ENABLE
#define RESET_PIN 3
#else
//reset pin is swapped to keypad when present, frees up additional input.
#define RESET_PIN 15
#define AUXINPUT2_PIN 3
#endif

so is i2c strobe set, when it should not be (i havn't selected the MPG and keyboard etc.)

thoughts?

[terjeio]

Incorrect map file, fix commited. The new server has been updated.

[customsolutions]

Back again, had to take a break and work on some other projects.... I have been following and read back thru posts but did not find anything on this.
I used webuilder, nucleo-f446re and cnc shield, i did select lightburn ppi, and cluster, 3 axis cartesian etc. When lightburn recognizes it as grbl_lpc. Any experiences/thoughts on that?

[customsolutions]

Btw, i selected ppi and cluster just to play with them. Dont know a ton about them or if that is related to the lpc issue

[terjeio]

grbl or grbl_lpc seems to be the two options available for grbl based controllers. grbl_lpc is seemingly automatically selected if the LightBurn clusters plugin is enabled. You can switch to the grbl profile manually if you want to.
BTW a better place for LightBurn support is likely their own forum - I have not used this software myself yet.

[customsolutions]

Actually here ended up being exactly where I needed to ask, because in your response you answered my question. It was because of the clusters plugin. So thank you. Not even sure if the clusters plug in is useful in my application. Currently just a nucleo with arduio cnc shield.
Thanks

[Dietz0r]

Quick question: is there a reason that the flexihal board map (STM32F4xx) is not included in the webbuilder?

[Dietz0r]

okay, so apparantly there's a python conversion script for .hex to uf2 :) so i dont need to touch the DFU or bootloader! :)

link to script: uf2 conversion script
link to source: uf2 bootloader source

[engigeer]

I think this might actually be the source for the flexi bootloader: https://github.com/Expatria-Technologies/tinyuf2

[Dietz0r]

I think this might actually be the source for the flexi bootloader: https://github.com/Expatria-Technologies/tinyuf2

correct, but the uf2 conversion should be the same

[engigeer]

It uses a custom version of grbHAL and I do not have a board to verify with,. I can add it if anybody verifies with the upstream code.

Would you be open to me submitting a PR to add some files necessary to facilitate building firmware for the flexi with the upstream code? I believe we can get it to be minimally functional with just a linker script and the uf2 conversion files, but there are also some spi and i2c customizations by Expatria that might be nice to include (with appropriate code guards of course).

[terjeio]

Would you be open to me submitting a PR

Yes - then I have something to comment on if needed.

[jubazdk]

Hi again...
I wrote not long ago about H7XX build failed error 422. And the missing 22mΩ for the TMC 5160T PLUS.
I think there is an error in the same build for the H7XX (SKR 3 EZ and TMC5160T PLUS).
When I try to set the current for the stepper motor it errors, (Error 2 - Bad number format | Missing the expected G-code word value or numeric value format is not valid.)
I just tested it with the previous firmware, witch works, and just now with the latest, and it errors.

Best regards Jubaz

[terjeio]

Which command?

[jubazdk]

In Iosender - Settings: Grbl - X-axis acceleration, if you change the mA value it errors.
(Bad number format | Missing the expected G-code word value or numeric value format is not valid.)

[jubazdk]

Sorry X-axis motor current..

[terjeio]

Odd, if you set the current from the MDI with $140 do you get the same error?

[jubazdk]

Sorry did not try that, and I just left... but the last firmware I build (web builder) just befor you fixed the 22mohm for the TMC5160T PLUS worked fine setting the current for the stepper motor.

[jubazdk]

It is not only the x axis, y, and z gives the same error too, just to let you know since you wrote $140

[terjeio]

Try a 50 milliohm build - working?
There is a buffer overflow with 22 milliohm since max current passes 10A, max validation value is four digits (9999 mA).
I'll fix the overflow in the next commit - I never expected TMC drivers outputting > 10A...

[jubazdk]

IRMS 10.6A and peak 15A.
I will try the 50 milliohm tomorrow and report back. Thank you for your help.

ESP32
Makerfr 2.0 board

I was wondering if it would be possible to add this board to the web builder?

[terjeio]

It is, but a board map has to be added first. For that the original source code or a schematic is required - and I am not able to find any.

Appreciated!

[BigFish11256]

Hello. Tell me what to do? The board is MKS DLC32 v2.1. I enabled WiFi "access point" support in the settings, enabled webui support, and flashed the board. I opened the smartphone, but the access point does not appear in the list. Do I need to configure it somehow or should it appear immediately after flashing? The firmware itself works and GRBLControl connects to the machine.

[terjeio]

$73 is set to 2?

[BigFish11256]

There is no such setting. If you enter $$, then there is no such setting in the list that appears. If you enter $73=2 ($73, $73=1, etc.), then it says: $73=2 < error:3

[terjeio]

Are you sure you flashed a wifi enabled firmware? When I rechecked with a fresh Web Builder build it worked for me.

[BigFish11256]

Yes, it seems I have a problem. FlashDownload Tool says that the firmware has been transferred. But nothing changes. I tried clearing the memory and now the board shows no signs of life at all. It also says that "firmware has been transferred" and "finish", but without changes. "Brick Board". Flashdownload Tool version 3.9.9. It's strange, but version 3.9.7 doesn't want to connect at all, although the settings are the same. It hangs on "Sync", only dots appear in the console.

I tried to download the original firmware from MKS and their flashing tool - MKS Laser Tool. and the board worked, even a wifi access point appeared. But this firmware GRBLHal and FlashDownload tool do not work. Before this, everything worked and was flashed without problems. I don't know what the problem is.

[terjeio]

The MKS board is odd - I tested with a dev board and that is easy to program, the MKS board is cumbersome. Perhaps this helps?

[Tinman-FP]

Are there any plans to add the BTT Kraken Board?

[dresco]

No current plans (hard to keep up with all the BTT boards), but is probably easy enough to add. Do you have one for testing?

First thing would be to run through the schematic, and check the pinouts. Feel free to raise an issue in the H7 repo, and I'll have a look when I get a chance.

[Tinman-FP]

I do have a Kraken board for testing.  I am willing to help in any way I can.  I also have the pin outs etc.V/rBillOn Sep 7, 2025, at 4:27 AM, Jon Escombe ***@***.***> wrote: No current plans (hard to keep up with all the BTT boards), but is probably easy enough to add.

Teensy 4.1, T41U5XBB, Native USB.
No connection to ioSender 2.0.46, DispatcherException: Unhandled exception occured: Port is closed!
No connection to Gsender 1.4.11 or 1.5.4.
Installed web build made 14 february and got connection again.

[terjeio]

My BB board is in the workshop, I can update that tomorrow. BTW the Pro board only differs in a couple of pin definitions so strange if that should be an issue.

[terjeio]

Ok - "Spindle on/off" is the issue, it causes a crash and continuous rebooting. Will check.

[Jon-Norberg]

I can go on with pwm option, no worries, I just use enable pin.
I got another web-build error, when I had keypad plugin i2c and display-plugin i2c ssd1306 at the same time. Do they use the same i2c adress, is that why I get an error? Afterwords I learned that I should use "generic" i2c display to get the Expatria jog2k to work, so that is what I intend to test tomorrow and that compiled fine.

[terjeio]

Fix for "Spindle on/off" committed. The ssd1306 compilation error is either due to a platform setup issue or an incorrect include path in 3rd party code, I'll check that later.

[Jon-Norberg]

Thanx appreciated!

[Bartekn86]

Hi, im newbie in Uc so please be patient ;-)
If I understand correctly, there is avalible imxrt with aditional 8mb of PSRAM. Will this RAM be available on the firmware that Webbilder builds? Will this somehow accelerate the machine's maximum speed? I'm ignoring the physics, which can handle it - it's just about the calculation speed (the processor speed won't increase relative to the board without PSRAM, which I'm aware of).
he funniest thing is that I don't really know how to ask the question.

[terjeio]

Will this RAM be available on the firmware that Webbilder builds?

No, it is not needed.

Will this somehow accelerate the machine's maximum speed?

Maximum speed for what? The only way to harness it would be to add a RAM-based filing system and download gcode to that. That may increase how many gcode blocks (lines) that can be read per second. But since the iMXRT1062 is very fast to begin with I doubt that will have any practical application.

[Bartekn86]

Hey, thanks for the answer, that's exactly what I wanted to ask, using clustering and grayscale, (lightburn) + jerk acc, the number of blocks in the CPU frame is related to the engraving speed, and the question is, is there any option to use this additional RAM for this by modifying the fw... just switching from atmega to imxrt did wonders, but with the 60w laser that I want to buy, I'm afraid that the limitation will still be the CPU/RAM

[phil-barrett]

I believe 1024 is the max, more than enough RAM on the Teensy for that.

[Bartekn86]

Thank you. Someone wrote somewhere that 1024 is only about 40k RAM? Could this information be true?
I'm planning to buy a 60W laser and I'm looking for the physical limits of the machine's capabilities.
The working area of ​​my laser is 1m x 1m

[terjeio]

A planner block occupies ~100 bytes of RAM, more depending on number of axes (increases if > 3) and if jerk is enabled.
$$=398 outputs this info:

$398: Planner buffer blocks, range: 30 - 1000, reboot required

Number of blocks in the planner buffer.

NOTE: A hard reset of the controller is required after changing this setting.
ok

So max is currently capped at 1000, if enough RAM is available. If not enough RAM the size is reduced dynamically to a size that fits, minimum 40 blocks. The actual size is the first number in the [OPT:] element in the $I report.

Since the planner buffer is constantly accessed to recalculate the acceleration profile there will be a size where the impact of this recalculation will start to negatively impact performance, this depends on processor speed, flash latency (for most), number of axes and whether or not the processor has a FPU. Increasing the size from the default 100 is only beneficial for high speed operation when a lot of short movements are commanded, e.g. for laser engraving. Note that another cap on performance could be the connection - if UART based the baud rate may be the limit. Some drivers or boards falls back to UART if "native" USB is not available, e.g the ESP32 does since it uses an off-chip UART <> USB converter.

[Bartekn86]

Thanks for the reply. In my case, 3 axes, jerk acc enabled, Teensy, as we know, has native USB without unnecessary FTDI, etc. Teensy has an FPU. I'll set the buffer to the maximum value, and I'll see where the processor limit is in grayscale. By the way, I wonder at what point the diode's speed will become the "laggard." The PWM speed is supposed to be 5 kHz, but it's doubtful the diode will reach that speed (on off time)

[Bartekn86]

update: bufor @1k grayscale 25m/min (show in iosender) 10w laser ends with 7m/min

[bullestock]

I'm considering buying a BTT SKR Pico, as MPG seems to be supported properly on that board.

[terjeio]

ESP32 code fixed, the mode switch pin is only available for the MKS Tinybee board (untested). Most ESP boards are short on pins so not easy to support signal based mode switching for them, use the mode switching realtime command character (0x8B) instead?

[bullestock]

@terjeio is there any reason why IO5/25/26/27/33 cannot be used on the DLC32? All those pins are available on EXP1/2.

[terjeio]

is there any reason why IO5/25/26/27/33 cannot be used on the DLC32?

Mainly time. I have to eat and sleep now and then... Can you try with adding

#if MPG_ENABLE == 1
#define MPG_MODE_PIN            AUXINPUT0_PIN
#endif

to the map file?

[bullestock]

Success! Thank you so much, I'll put together a pull request.

[terjeio]

A typo, fixed now

[pmolz]

I think that the board map for the PiBot 6-axis I2S is missing a lot of the auxiliary pins, making configuring a probe and tool setter not possible at the same time. In addition to GPIO.2 which is already defined, there's also input 26, 33, 32, 35, 34, 39, and 36. Also does anyone know if you can build grlbhal with the latest version of ESP-IDF or do i have to downgrade.

[terjeio]

I have updated the board map to assign unused limit inputs as aux inputs and remap of the relay output as toolsetter input when it is enabled. To use the toolsetter a link has to be changed, see the PiBot documentation.

To build locally use the ESP-IDF v4, there are breaking changes in v5 and I see no reason to change as long as v4 works. I may do it on a rainy day (or a week?) if I am am bored and have nothing better to do. Or if you have time can you update, fix and reverify?

[pmolz]

Thanks, those changes look like they should have worked in theory. But I have messed with the web builder a bunch and still cant get it to enable the toolsetter without it saying "DIGITAL IN: available 0, required 1.". Am I missing something obvious?

Also, can you clarify what link has to be changed to use the toolsetter, I couldn't find any usage recommendations in the PiBot docs.

Also no worries about the v4, was just wondering if the readme was outdated or something. I'll see if it just works with minimal changes though.

[terjeio]

I have enabled one input in the Web Builder - later I have to add logic that changes the number of inputs depending on number of axes/auto squared motors selected.

Also, can you clarify what link has to be changed to use the toolsetter, I couldn't find any usage recommendations in the PiBot docs.

Search for this text:
"By default, GPIO 26 serves as a relay output. You can also change its jumper to use it for input. Insert on the left for relay operation and insert on the right for terminal operation."

[PeterMolzer]

Thanks you're awesome

[thommo17]

Hi Terjeio,

I've just tried to update the firmware for my GRBLHAL2000 teensy controller but it doesn't work when I complete the flashing.

The flash seems to go ok but when I tried to connect with IOsender it will say the connection isn't open and I can hear the USB sound going every few seconds like it is connecting and disconnecting.

Last time I did an update from the web builder was 08 Feb 2025.

I also noticed that if I have the probing plugin selected this time it will give a 422 error on building

Below is the json from the last working firmware

Thanks :)

[thommo17]

Brilliant. I'll give it a go and see if it works

[thommo17]

Tested and working

[thommo17]

The other day I only tested to see if the flashing worked but not actual functionality.

After updating I can't zero the machine. If I press zero all in IOsender it will work but it will still show whatever was already in the WCS boxes as what it was prior to the zero all.

If I reload IOsender the numbers will be all 0 and if I go into the GRBL setting page and press reload it will also bring them to all zero when I switch back

[terjeio]

This is due to a regression, fixed now.

[thommo17]

Jeez you're good. I'll have another go when I get the chance

The Web Builder definition was incorrect, fixed now.

[JasonTitcomb]

Is this a false error message for the T41U5XBB also?

[terjeio]

@JasonTitcomb No, since the board has only one serial port available. The board map can be changed to allow two if the I2C port is not in use but then you have to compile yourself - there is a limit to how complicated I want to make the Web Builder.

Fixed now.

[marc-meijer]

Thanks for the fix! I can now also compile it locally with PlatformIO. The firmware flashes, i.e. firmware.bin is renamed to FIRMWARE.CUR. I can't connect to the board with USB-C though, the USB port isn't enumerated by Windows. I'll see if I can investigate further but any suggestions are welcome.

[marc-meijer]

Possibly related to USB issues described here:
BTT OCTOPUS PRO BUILD #259

BTT Octopus Pro F446 build #141

[terjeio]

Does it work if you flash a non-bootloader version with DFU?

[marc-meijer]

I've not tried but I have a cheap ST-link that is arriving tomorrow and hope to get some info on what is going wrong. I'm also trying to set the clock configuration in main.c so that the USB clock is 48 MHz by copying the clock configuration from the Octopus Pro Marlin firmware repo to main.c. Since the Octopus Pro F446 has a MCU clock of 180 MHz the clock configuration is different. But I haven't been successful so far (see BIGTREETECH-OCTOPUS-V1.0 )
