Just starting my new project on the 48x30 long Mill. I’m having issues with X axis
Runs fine up to about 4” left side and stalls , and then will stall approx 12” on right side.
All wheels turn as directions- this is my second long mill - have checks backlash
Not tight
Thank you
I had a similar issue with mine upon assembly. It turned out to be the anti backlash nuts were not seated properly. Try backing off the screws completely, you’ll have a lot of slop but it should move freely without hanging up. Then slowly tighten screws a little bit at a time. Eventually it will seat into place. I manually ran the x axis back and forth a few times until it was smooth.
I did play with it a little - seemed to help a little - I will loosen up more and run back and forth.
Thank you

This can be an issue with delrin lead nuts. They are very sensitive to adjustment and wear-in. I had a similar problem on my genmitsu machine. Seems to be fine now.
I did loosen the screws, and this did help on the left side. I can traverse -
Rapid, normal and precise anywhere except 8”or less to the right end where it sometimes goes all the way in Rapid or normal but sometimes
Gets hung up and won’t move unless I push with my hand. Trying to use
Precise setting will move (maybe) but stop either left or right on this far
Right side. I did this back and forth for about 45mins
Are you able to turn the x-axis lead screw by hand fairly easily? Make sure the bolt that crosses the gap in the anti-backlash nut is also backed off (I had to back mine out quite a bit and re-adjust).
