General Mach Discussion / CNC Router will always fail the first toolpath

« on: September 13, 2021, 01:39:35 PM »

Hi there, I've recently bought a  Cnc Router to use it in my workshop (Woodworker & Guitar Maker). It's been working just fine until recently. I have a problem where the cutter will dig straight down as soon as it starts (the depth is always the same as the first pass of the pocket it's supposed to cut). When I add a drilling toolpath to a random place where it doesn't matter (waste) the problem seems to go away however it'll fail to run that drilling toolpath to the right location, it runs the drilling toolpath on the corner of the workpiece (where it dives down when it's not supposed to), When I say the corner of the workpiece I meant where I manually set X0 Y0 Z0. I'd like the machine to not ruin the pieces I'm tring to cut without adding unnecessary drilling toolpaths at the start of every job obviously. The way I explained thing probably show how much of a newbie I am. I use Aspire and Mach3, as I mentioned I have successfully ran more than 50 jobs before this started happening. I tried adjusting the Safe Z and Homing/Limits setting (without having any real knowledge on how they work I might add).  I'd appreciate any help at this point, Thank you for reading.

Cheers,

Mehmet Çınar
