Well I picked up the conversion kit last Monday and overall happy with the kit. I do have some minor complaints about it.
Everything bolted up and fit as it should. I wasn’t disappointed with the cast iron bearing blocks and motor mounts and they justified the 8 month wait for this kit.
I ended up getting some cheap Nema 23 570oz dual shaft steppers instead of trying to fit the 34’s I already had. I made some adapters for the shafts to work since they were 1/4” also I could still use the hand wheels. That’s when I noticed something was off.
The Y axis ballscrew is the same hand thread as the X axis! Therefore the Y axis moves in the opposite direction as it normally would. This was disappointing, I took the extra effort to still have hand cranks but can’t really use them.
The other thing that wasn’t so great was I have approximately .001” backlash in X and .003 in Y. Not sure if it’s on the ballnut or if it on the shaft coupler. I welcome any suggestions on remedying this. I can’t pickup any axial play on the shaft.
Other than those two things, I’m happy with the kit. I haven’t installed the Z axis yet. I wanted to have it somewhat of a manual mill with contouring capabilities for now.
I’ll post some pictures of the adapters I made when I get a chance. Also when I get my limit switches mounted. I printed up some brackets and need to test fit before I make them out of aluminum.
Also printed a little wrench to snug up the lock nuts.
