So I’m new to CNC but over past few days I’ve been running jobs with material 1/2" thick and they ran fine. Started doing some 1/4" thick material yesterday, first project ran fine.
Now I’m trying to run this current job and all day yesterday and for some reason it’s cutting through the material. Cut depth is 0.13" material is 0.25" thick propped up on some 3/4" wasteboard. Material thickness in Vcarve is set to 0.25".
Someone last night recommended that maybe I have a bad ground or static electricity build up and it’s cause interference from carved material laying around. I blew everything off, I remade the entire vcarve file. The design, toolpaths, everything. Reran the design on an already ruined scrap piece of material and it ran perfectly fine.
This morning I’m like okay, let me run in on another new piece of material since it worked. Same exact CRV file. Now it’s cutting through the material again. Any help/ideas?
Machine is a Shapeoko 5 Pro, Designing in Vcarve 12.5, using Carbide Motion to run the gcode to the machine
Upload the (zipped) .crv file (some folks here have it) and the G-code file.
Our ability to troubleshoot 3rd party applications is quite limited, and our recommendation is to make a pair of files as similar as possible in Carbide Create and the 3rd party application — if the .c2d file also has this problem, then we can work with you to troubleshoot this, then the fix can be applied to the 3rd party application — if it doesn’t, then the G-code from both applications can be compared and hopefully the fix identified and applied.
So I’ve picked up its not file. It was the machine or carbide motion. When rapiding to my Z zero which was ontop of or just just minimal above my material it would end up running into it. I was able to correlate it with everytime it would do this it would end up squeaking at the top of it’s Z motion, I presume trying to move past it’s limit when it couldn’t. I’ve reran trying to zero the Z 5-6 more times and I’ve heard 0 slamming once it’s moved to the top of it’s Z range of motion and hasn’t been making contact with the material when I rapid it back down to it’s material. I’ve ran 2 little stars from my design as test that have carved fine and I’m now running the entire job itself and itself about 1/3 of the way through and has ran fine.
So I found the correlation but still do not know the causation. Seems to be working fine now though.
If you still have trouble, please send in the .c2d file and let us know step-by-step how you are securing your stock and setting zero relative to it and managing all tool changes, and send a photo showing the stock in place and the machine at the zero position relative to it (or a specified offset from that position) and screengrabs showing what Carbide Motion shows for Position and Machine Position (click on either to toggle to the other).
