ive been making some hole plugs for work. made many many many of them. now all of a sudden anytime i create a toolpath in f360 first thing it does is go to the top of Z and hits limit switch. I have no idea what ive changed but its had me stumped for days. below if the first few lines of code, any help or ideas would be greatly appreciated!
If you jog to where you think XYZ zero should be, and it isn’t showing values in the DRO that are close to zero, you’re zero isn’t set properly for whatever reason, and would readily explain why that first move wings you off into someplace you don’t expect.
@neilferreri’s comment made me remember I once had a similar problem where for some reason my GRBL has lost its G28 reference, this may have happened to you if nothing else changed in your workflow.
Quick fix: home the machine, send “G28.1” (without the quotes) using the MDI.
If as I suspect you are using the Carbide3d post.processor in Fusion, you don’t have the option to disable G28 retracts (at least the version I have installed doesn’t). You can (and should) reset G28 using the G28.1 command as decribed above, you could also jump ship and install @neilferreri’s most excellent post processor for the Shapeoko, and then you’ll have the ability to customize whether you want G28 retracts or not (as well as other options)
