Has anyone tried the tension test function in the options menu where you hit the arcdroid logo 5 times? Everytime I try I get an error :M930 did not reach error threshold, arm not held or belt slipping.
I’ve tightened up the belts as @Andrew video suggests. Worried I may have gone a little to tight trying to past this test.
Also when locked by pressing zero twice it’s fairly easy to overcome the motors for the big arm by just pushing lightly on the arm, makes a clicking sound and doesn’t look like belt slipping just motor turning.
Any insight or info on this would be greatly appreciated, I started looking into this when I could no longer cut a perfect 3” square after calibrating.
That function is not really designed to be a user test. We only use that with a special fixture at the factory to confirm belt tension.
So it’s unlikely that you are going to get a good result
The best way to tension the belts is to back them off until they are loose and then slowly tighten half a turn at time until all the slack is gone at the end and then give it one more half turn and call it done.
Overcoming the motors in hold position is not too difficult if you feel that one motor is a little softer than other. Double check that your driver current is the same in machine settings.
Settings→ machine settings→ driver current→ x&y should be set to 1,600
Thanks for the reply. I’m having a heck of a time cutting a simple 3” square with square corners ever since I tightened the belts. After I tightened I calibrated the machine. Not sure if that was it or the belts. Loosened belts off and tried again with your instructions but it’s hard to tell what tightness is correct. Maybe opening up and checking would be easier? Adjusted best I could and re calibrated again…and still very sloppy 90 degree corners. I’ve been struggling with this for hours and very frustrating. It all started when the x2 didn’t light up on a cut so I decided to start doing some maintenance (adjusting) and it’s gotten worse. Not sure what the next step is. The last calibration I pulled the droid off the x2 and put on a heavy piece of plywood and screwed square down to ensure a good set point. Re connected everything and out of square!
