The stops are nothing to do with the stepper motors. I had the same issue, I disconnected all the steppers and the spots where it stops were still there. I adjusted the eccentric adjusters for the guide wheels and it solved it.
Can you not just move the cord so its on top of the frame? It shouldn't sag and touch the work surface then. I have watched a few videos of the P9, and this comes with 4 raising blocks that you use to assemble it. If you use them before tightening the frame up then it 'should' tighten the frame 'square' and shouldn't sag. Or you could just move the head to the end of the arm with it touching the bed before tightening and that should also make it square.
The cord isn't quite long enough to go over the frame, it will make the machine bind when it extends all the way. This one came with the 4 raising blocks as well, I used them to assemble the laser per the instructions. I think its just going to sag regardless. The beat thing to do if you're doing a larger piece is set the focus with the diode all the way out on the arm. Worst case its a tiny bit high when its closest to the frame, but it didn't seem to make a difference in my testing.
@@ReeseCustoms I received mine yesterday and set it up (still a lot to learn). The cord to to the laser i placed over the laser arm (X axis), not the main frame arm itself (Y axis). This clears it away from the laser head where it touches the work surface, and there is no way it will interfere at all. So rather than going from the socket, under the arm then up to the head socket, go from the socket straight over the arm (hope that makes sense). I will try and do a video to explain it and show it working on my RU-vid channel if it will help.
No problem. I don't mind reviewing products when they send them to me. I'm very transparent and want other people to k ow the truth about things, whether they are good or bad.
