Hello everyone. This machine is quite poor. One motor is not retracting with the rest of the motors. I haven’t cut a single thing yet. The machine moved to the upper left corner, stopped moving (error code as usual) and now the motor doesn’t retract. First time running a job and I’m guessing it already died?

more likely there is something wrong with that arm (something jammed in it)
there should be a little bit of play in the spool, can you wiggle it a little
like the others?
you may need to take the one arm apart to see what’s up with it.

Thanks for the reply.
It seems that it’s a software bug. I lost count how many times I had to reset and extend and retract until the arm just started retracting again.
However now I’m have issues with one of the z motor not turning. It seems to be energized since I can’t turn it by hand, but does not move when send via the software. The other one works fine. I tried reseating the connector but nothing seems to work. Any ideas?
Does it do this even when the power is off?
Ok actually it doesn’t seem to have any holding torque at any point.
Powered off, both motors can be turned by hand. While on both can be turned by hand also (except when the one working one is turning of course lol).
This is the 2nd time I’m using it, no cuts previously only one calibration cycle completed.
That fits with what I would expect. There is a fairly common issue where we had a batch of board where some of the stepper motor drivers weren’t fully soldered. I will DM you a code for a free replacement right away. I’m sorry for the trouble!
Darn! I was hoping to get some cuts in today. Alright, not much that can be done at this moment.
If I may bar a few point of conflict I had while building my kit. Overall great kit. However, in a few point where the provided screws were used, they were too short for comfort and had to use slighter larger screws at 14 mm. Such as the two screws at the ends of each arm near the servo motor encoder plug is in.
Also, it’s be great to perhaps have a delrin spacer as to take away the empty space between the top of last arm and the plate closest to the on/off of the router. I know movement is needed but I don’t think that much slack is ideal.
Thanks for the help anyways!
Yeah, I’ve been talking to the screw manufacturer about exactly this. When we switched from the allen drive screws to the torx drive ones they ended up bing slightly shorter. Even just an extra few threads makes a big difference.
