I think I’m continually disliking MM more and more. I typically use Gsender but thought I would try MM. I created a simple tool path. When starting it the spindle goes down. The spindle does not turn on but plunged the bit into my wood without turning
Your machine use a GRBL controller? If so, please enter $$ in the Console window and give us all the $xx parameters less than $100.
Why is this? What software have you been using beside GSender? Lightburn is different because the development environment and machine control environment is in one package. It is new and will take some getting used to. You learned Lightburn and the laser, right?
Back to your spindle motor…
Did you set the RPM in the Tool setup? That is where stuff like chip load is set.
If you imported a Tool Library, you should check every tool for the parameters that work for your application. You can have identical tools with different settings, like for wood or acrylic, or even dense foam.
When I run a new program, I ALWAYS dry run it, with no tool in the spindle. When I was a CNC Tech, I saw too many machinists break things due to program settings. Did you know a 60hp lathe spindle can snap off a 2” boring bar?
