I bought the CNC router that Andrew (coldfusion) built and and I've been having lots of fun with it. I plan to use it mostly for wood. I'm using Mach2, SheetCAM and MeshCAM. I'm cutting 2-1/2 D with SheetCAM fine, but when I try to do full 3D with MeshCAM from one side of the cut to the other the Z Axis creeps up (see image).
Andrew said he did not have this problem so it must be something with my setup and not the mill. He sent me an .nc file from CNCone and I had the same problem with it so I do not think it is a MeshCAM issue. Andrew sent me his Mach2 XML config file and I'm using that.
Any suggestions on how to troubleshoot this or what the problem might be?
