Hey Brandon,
I’d love to, but I’m quite scared to screw this up. I found the screen to test the limit switches- the y limit registers on the right side.
Is there a link or quick description of how to isolate and test the 2 y motors separately? I have a ticket opened so I’m hoping to speak with someone in support tomorrow.
Feel free to wait for Inventables’ Customer Service to reach out to you.
If you remove power from the CNC completely for about 10 minutes and leave it powered off, you should be completely safe in touching things. I would just check the stepper connections themselves and/or look for any burned marks on the stepper driver chips on the control board. If only a single Y-motor is not working, it is likely a loose connection or a blown motor driver. Obviously, you have to be comfortable looking at the equipment, but if you are not, it might be best to wait on a return phone call.
Brandon,
Thanks again! I did check for loose connections this morning- cycled through off/on with no luck. Although the left side still has power and can be jogged, it seems that now both sides can move freely with a firm push. Neither side is locked. This is while I’m able to jog the x, z and 1 side of the y.
I’ll be patiently awaiting the call from Inventables today. Although it’s an inconvenience (and potentially and expensive one), I’m sure I will understand the machine much better at the resolution. I’ll update for the sake of archiving the experience on the forum.
Update and solution. After a brief diagnosis sesh with support we determined it is in fact a control board failure. Simply swapping the y1 and y2 cables at the ports reversed the symptoms. Right side worked, left did not- ruling out a problem with the motor itself.
For better or worse, I will not be doing the rebuild. The part is no longer under warranty, but Inventables is taking the controller back to rebuild or replace for a $100 shipping fee. It is an unfortunate situation all around- but I am happy with the response and resolution from Inventables. They are shipping me a box to pack and return the unit which will be rebuilt or replaced. I am hoping to be running again in 8-10 days.
Moral of the story- shut down your machine when it’s not in use. My controller is tucked away in a dust-protected space under my table, adjacent to my computer tower. It is inconvenient to turn either off- so I just put the computer to sleep. Don’t do this. If I had been a little more diligent I may have avoided the situation
