I have had my Pro XXL for about 6 weeks. Since the initial assembly, the x-axis movement has not been very smooth. Initializing the machine created noticeable vibration when moving along the axis (compared to the y-axis). Despite this, I was able to move forward and complete a few short cut jobs over the first few weeks.
After a while, the z-axis started “slipping” when moving along the x-axis rapidly and could not complete the initialization cycle (z-axis never reaches the x/y limit switches). I reassembled the axis, cleaned/lubricated the rails with Vactra No. 2, re-tensioned the belt, and reconfigured the machine in CM. This allowed the initialization to complete, but the vibration still remained.
After about a week of minimal use the “slipping” returned. I completed the above steps again, which and had similar results. This brings us to where I am now. Sometimes I can complete the initialization, sometimes not. When I do, the machine will eventually fail during a cut job with the x-axis stuck not moving at all, just constantly “slipping” in-place.
I have provided several videos that show the condition of my machine, and what exactly is going wrong during a simple concentric circle operation I created specifically for this purpose. Any help or advice whatsoever would be greatly appreciated! There is probably a simple fix, but I am out of ideas at this point.
TLDR: X-axis movement issue. See videos at link.
