im not really sure how this mess of parts is possible. weird. can you confirm the gantry ball screw is not also too short and the back plat on the gantry lines up? i imagine it does, but we cant see it
easiest solution is to pocket the end frames wider on one side. leave the other alone. but youll need a mill and larg-ish vise for this.
proper solution is to cut the gantry rails shorter. but youll have to re thread the ends, the cut the back plate, and possibly shorten the ball screw. so may not be doable.
Then gantry ball screw doesn’t seem too short. This is my first CNC bios obviously so I may be wrong. Take a look at the pics and let me know what you think.
As far as the back plate.... there isn’t one. That was actually what started this thread. It seems that George left that part as well as a couple of others out.
