Well, I fired up the machine last night for the first time. I have the @#$% slipping couplers problem. The X and Y axis’ moved very easily after tuning during the build. The couplers are crap. Actually, the bearing rail system design is crap too, but cheap I guess. I may convert it over to a linear bearing rail out of spite for crap engineering. Very disappointing to go through months of methodically building this machine only to be let down.
I’m going to loosen all the bearings today and see how it performs. Still though, not even a three star experience Langmuir. This is my fifth CNC machine. My second was a custom 3D printer that I built from scratch. I need this machine to build my next machine, a CNC router/mill.
