Just setup - Gcode problem

Resources Common Problems
1

Hi

I have a Workbee CNC and am using Optlaser 6W.

I have just installed Lightburn and am having problems.
When running the Gcode the laser only fires on the first vector, the CNC continues to following the rest of the image but laser is not on.

When looking at the Gcode the ‘S’ value only appears in the first line of main body of Gcode i.e. not Header. I am new to this and new to Gcode.

Help please.
TIA

What firmware are you running on the Duet? And what controller type have you picked. Not certain but perhaps an incompatibility there.

Does this happen with all laser operations? Or just vector? Can you share the .lbrn file to take a look?

Hi

I have only experienced this problem with vectors?

I am not at my work laptop now so cant share .lbrn file until tomorrow.

My Firmware is
FIRMWARE_NAME: RepRapFirmware for Duet 2 WiFi/Ethernet FIRMWARE_VERSION: 3.3 ELECTRONICS: Duet Ethernet 1.02 or later FIRMWARE_DATE: 2021-06-15 21:45:03

and I am using GRBL as my controller.

I have attached Gcode if that helps.

Thanks

I think RepRap is a Marlin fork. Try reconfiguring your device to Marlin and see if that changes behavior.

Thanks, I will give it a try.
