fritzw / xtm1_toolkit Goto Github PK

Hi I was working on a very similar project for the LaserBox Pro and somehow happened upon your work here. LightBurn supports networked grbl controllers now, meaning your app could take real time input from LightBurn, translate, and forward the gcode over the HTTP interface.

In your code comments you state that the correct Z value for a material of thickness 0 is 17, but you also say that empirically you found it to be closer to 19. What made you think it was 17? When I perform a "score" using xTool Creative Space and set the material as 3mm basswood plywood, in Wireshark I can see that it is setting a Z height of 17. This makes me think that the value for a material of thickness 0 would be 20. Is it possible you got mixed up somehow?

I thought, that the G-code from the XCS software was cutting at Z=17 for a material thickness of zero, that's where I got this value from. Also, the maximum material thickness I can set in XCS is 16. However, i may have made a mistake somewhere (seems likely, since the focus was that far off for me).

Here's a capture I made scoring a short line on 3mm plywood. The Z value of 17 is set at the start when all the other defaults are set, and then it doesn't get set again.

GRBL has some additional commands like $I or ? and some other idiosyncracies.

• Send replies to LightBurn when GRBL-specifig codes are received
• LB sometimes sends only X123 without G1 before it. Check if the laser understands this, otherwise add appropriate G command (G0 or G1 depending on the last seen command).
• LB leaves out the spaces beween parameters, like in G1 X5Y10S0F1000. Check if the laser understands this, otherwise add spaces.

Currently, m1control.py is very hacky and fragile. It can only run a single lambda function for each command line argument. There is also no way to specify the laser cutter IP address or usb connection.

Parse arguments with argparse and improve user feedback.
