Hi, my name is Toni. I'm testing Sheetcam. I have a CNC machine and I've adapted a diode laser to engrave and cut wood. I've created the cutting tool and set the power. Since the laser is low power, I have to make several passes. I do this by copying and pasting the operations; I don't see an option in the tool settings to select multiple passes. Regards.
I believe you are correct, there is no ‘# of passes’ field for Jet Operation when a Laser tool is selected. It would also be best to have a ‘Z offset per pass’ field such that the focal point could be lowered if the material thickness warranted such.
I’m a big fan of sheetcam. That said, I use Lightburn for all of my CNC laser jobs, CAD/CAM and even gcode sender. My CNC is multi process also, milling, laser, and plasma. It has a grbl v1.1h 4axis controller, thus conducive to Lightburn as gcode sender during laser jobs. Lightburn also supports a camera overhead of the work area, with 0.5mm image correction accuracy even to the extreme edges, removing lens distortion (fish eye effect). This allows for very accurate job layout on work material, especially remnants material. Lightburn is also my 2/2.5D goto CAD for plasma and milling/vcarve, sheetcam being the CAM, UGS being the gcode sender/UI machine interface. But I can still use the Lightburn camera during CAD if necessary.
Consider using Lightburn for laser CNC CAD/CAM. It can save the toolpath to gcode file for whatever your CNC is using for controller and sender/UI machine interface.
