So I recently purchased the upgrade kit since I was not happy with the reliability of my x-carve (x-axis movement and not enough power to my nema-23 motors most importantly). I also purchased the new eccentric spacers to replace the nuts I had before. The problem with the nuts, is they could undo them selfs. I’m hoping now with the nylon nuts locking them instead, this issue will go away also. I also beefed up the y axises by putting 3x L brackets on each Y axis, bolted in two places on each bracket and two places on the waste board.
Needless to say, I’m very happy with the lack of play now in my x-carve. However, my x direction is acting a bit funky and can’t seem to figure out whats going on. What it does is sometimes it will move and other times, it will not.
Here’s what I can say about it:
- First weird thing to me is I remember all axises locking once the machine is on before the upgrade. Now, all axises lock except the x-axis. The x-axis moves freely, despite the fact that it CAN, but will not always move when commanded.
- I have realigned the ecentric nuts multiple times. They are as loose as they can be while still being tight enough that they don’t slip.
- I adjusted the all of the pots to 2.8 amps, the value recommended by Inventables.
- I double checked the wiring is correct, and fully attached (no loose connections anywheres in the x-stepper motor cable)
I’m not sure what else to do. It seems weired that the x-axis motor does not lock when powered on. When I give it the command to move, it makes a noise and fails to move.
Any help is much appreciated…
