Hi all, We have a Lasersaur in our hackerspace and looking to upgrade to work with blackbox and lightburn. I bought the ESP version instead of arduino and all instructions around flashing are arduino. Any advice on how to convert or load up instructions for following configuration toolsDocs/Laser/Lasersaur_gcode/technical_details.md at master · openfab-lab/toolsDocs
You wouldn't use the old software at all anymore. docs:software:overview [OpenBuilds Documentation] 1) Stock BlackBox wired up as per docs.openbuilds.com/blackbox-x32 2) Run OpenBuilds CONTROL OpenBuilds Software: OpenBuilds CONTROL and OpenBuilds CAM 3) As the Lasersaur doesn't have a Z axis, set $44=1 and $45=2 in Grbl Settings to configure the X first, then Y homing sequence 4) Set things like steps per mm, acceleration, max travel, etc based on values from toolsDocs/Laser/Lasersaur_gcode/technical_details.md at master · openfab-lab/toolsDocs - by going to CONTROL > Grbl Settings tab Avoid changing advanced values, LaserSaur configs tend to be a little over the top. Start with our CUSTOM profile, set Steps per mm, acceleration and Max Travel. Enable Homing and Hard Limits. Configure where the limit switches are in $23 Homing Dir. Set Laser Mode $32 to Enabled. Keep it simple initially, standard configs are close. Lightburn can connect to the BlackBox too: docs:software:lightburn [OpenBuilds Documentation]

That would be You do it from scratch (as its a different controller) but can borrow inspiration from the old values. Will need tweaking either way as its a different controller Reading the Grbl Wiki is also a good idea
