Hello! im am having trouble with the Z axis, it goes all well while it carves, but at the end of the job it does not go up and out of the way to homing but it stays at the depth of the gcode file and cuts right through
1) Include the GCODE 2) Tell us what CAM you are using The machine just follows your gcode, so wherever you are generating the gcode, its configured incorrectly
You gcode goes to Z +3.81mm above zero at the end of the job before it goes to XY0 If you zero on top of the stock this should be safely above it. Are you sure Z is calibrated? Are you seeing any stall in Z (mechanical slip, or acceleration/max rate set too high, or spindle too heavy)
Z goes up and down smoothly when carving, if i move it when it is not running a carve i have to lower the jog rate or it slips. Should i lower the feed rate when it terminates a carve and goes to home? where can i do that?
Acceleration or Max rate too high: Grbl v1.1 Configuration G0 Moves follow the Max Rate not whatever feedrate you set for G1/2/3 Quoted from the Grbl Wiki And the line it fails at is a G0 Could also be acceleration too high: Grbl v1.1 Configuration
I lowered the speed and acceleration rates for le z axis and it goes up and down with no problems now, but it does not come up when running a job or at job done, what else should i check ? I also tried carving free hand with the jog toggles anche the z axis goes up and down with no problems
slow it down more (half the maxrate, and half the accdeleration), the jog is not at full speed, but G0 moves are at full speed, and clearly that is failing to lift the weight of the router, now do a movement test, NOT jog, opent he serial console and issue real commands zero Z about 25mm above the spoil board give the commands G21 G90 G0 Z-15 G0 Z15 that will move down 15mm and then move up by 30mm to Z15. if that succeeds then Gcode will succeed.
