[Feature Request] CV Laser Support

[Avedena]

Is your feature request related to a problem? Please describe. If you want to use the Creality CV Laser its needed to flash the Board with the Creality Firmware. Also with the Creality Firmware, there is no support for Lightburn. With the Ender3V2S1-Firmware i get the following Error:

Error:!! STOP called because of BLTouch error - restart with M999 Error:Printer stopped due to errors. Fix the error and use M999 to restart. (Temperature is reset. Set it after restarting)

Describe the solution you'd like Id like to use this Marlin Firmware with LightBurn. For this, its needed to enable the Marlin Spindle/Laser Support in Firmware. https://marlinfw.org/docs/configuration/2.0.9/laser_spindle.html

Describe alternatives you've considered For every Laser Job Flash the Firmware with the Creality Stock one.

Additional context I am a newcomer to 3D printing / laser engraving. I have already tried to compile the firmware in Visual Studio Code myself, but LightBurn still does not recognize the laser.

With the Creality firmware I can move the axes, but I quickly get the error that something is wrong and I should fix the (unknown) error and restart the laser with code M999.

With the Ender3V2S1 firmware, not even the axes can be moved.

Hi, thank you for your feature request. Currently, adding support for the Laser unit to Professional Firmware requires some work and time. I hope that someone can do a pull request adding this feature. I don't have an S1 and not a Laser Engraver to test, so for me it could be a little difficult to give a firmware with the tests that I expect.

Hi, I try my best to get this done. I Have a S1 and also the CV Laser module. Have you some starting point for me? I think the first modification is to allow Z-Homing without the BL-Toutch and insted use the Z-Linmit switch.

The Sources for the official firmware with laser module are here: https://github.com/CrealityOfficial/Ender-3S1/tree/ender-3s1-lasermodel We must port the Laser code without affecting the core Marlin code.

I will digg deeper in this topic. Can you explain, how I change the machine type in the Marlin auto build tool? I think I was building for the wrong Machine.

You must copy the correct configuration files, from the Configuration folder to Marlin Folder.

I see, but what are the diference between the xfer, maple and none? And also the 256K and 512K? I build the STM32F103RE_creality (512K) and sucessfully installed to the board. Now I'am working on the port. Thanks.

[mriscoc]

For the S1 use the STM32F103RC_creality (that depends on the type of chip that your control board has)

I don't think Z-homing is important for the laser since you need to do it manually depending upon the height of the item that you're cutting/engraving so it definitely shouldn't try to use a limit switch. When homing using the Creality laser firmware it only homes on X/Y.

You're right. At the time writing this, I don't have enough experience with it. I was thinking the additional Z-end stop is for the Laser Head. But I'm still working on this.

Hi there! I'd like to deep into the topic. I've been working into porting the code from the original repo but I'm getting this issue when compiling. I don't know if someone can give me a tip for it:

For what I understand it means that the code does not fit into the board memory but it doesn't make much sense for me since I didn't add much code at this point. Am I missing something?

[Avedena]

Hi @aydevosotros , that is right. To save some space, you can disable some UI features.

[mriscoc]

The STM32F4 boards have a large bootloader, so the program memory space is shorter than others boards.

I, too, am interested in laser support. What all would have to be removed from the Ender3S1-F4-UBL firmware to make room for laser support? How thin are we on space? Do we have laser code readily able to to be combined into a build?

Preliminary laser support is being discussed here: https://github.com/mriscoc/Ender3V2S1/discussions/62
