Hi,
I am a brand new Shapeoko owner. Just got the CNC a week ago and finished setting it up over the weekend.
I purchased some plans to make some work holdings and had some issues with the L Brackets that I made. The outside contour was correct but the inside was wrong. The program is using pockets to make the holes on the inside. Looks like it’s making “outside” holes instead of inside holes.
Can anybody help please?
Not sure what I’m making wrong.
Thank you
Post the file — it could be an unclosed path or a wrong toolpath selection.
Kind of looks like you’re using a too large bit for the tool path
Im using the bit that came with my machine, #201. 1/4" endmill.
I used the BitZero to zero in X,Y and Z

Those look a lot like Myers Woodshop brackets. Mike Myers made those some time ago in a previous version of cc. Don’t remember what version I was going to make them again but I had similar outcome. However I made them with 4.74 and they came out good. Maybe it is a version compability problem. Have not tried them with 5.x yet.
Yes. They are the Myers Woodshop brackets. If I can’t figure it out with my current version I might try it with 474 as well. Is there a way to download an older version of cc?
I saw that the preview looked good. I’m not sure if I’m doing something wrong or how to fix the problem.
Since this was some time ago I cannot remember but I may have deleted the tool paths and recreated them in the current version I was using at the time.
Is it possible that the tool offset is set to “Outside” on your tool path, which would enlarge the holes?
Well, that’s what I thought. But the tool path is a pocket. Therefor there is no selection if outside or inside.
@mjmuschket Any chance the gcode you shared is not the gcode you actually used?
or, are your tool paths generated for a smaller tool than you are using?
I think I figured it out.
I did what Guy Donham suggested.
I deleted the original toolpath pockets and added them again.
It fixed the problem.
Thank you
