Attempting to cut all the drawer parts out of plywood, 2’x4’x3/8". Testing it out to see if it works easy enough.
The file is a little funny, but I created tool paths for the parts that make up one drawer first, then added tool paths for parts of the second drawer. The second set of tool paths ran incorrectly on the plywood. See attached pics and file.
Thanks Tony - I forgot to mention I have the Shapeoko 5 Pro (no belts) with Carbide VFD spindle.
It seems to have run the other things fine. However, the drawer bottom (large rectangle) on the upper right and the right drawer face (two center rectangles with pockets) seem to have moved left when the machine was cutting.
it does look like either lost steps or slippage on the X axis:
lost steps can occur if you are too aggressive on feeds and speeds / depth of cut. What settings were you using? It can happen that some aggressive settings “work” for most of a job, but are borderline too much and fail (produce lost steps) on a particular section of the toolpaths. No idea whether this is what happened here, but telling us about your cutting parameters will be useful to rule it out
slippage can happen if the coupler between the motor and ballscrew is not installed or tightened correctly. Double-check that X coupler?
