I presume you’re referring to the ‘motors jammed’ error and this is designed to detect when a part of a print is stuck in the tank. Generally, this gets thrown when the wiper or another motor doesn’t return to its home position in the amount of time the printer would expect. Excessive peel force can cause this as well but it tends to be fairly noticeable when the tank is struggling to peel.
I’ve seen this thrown by mistake a few times and if you checked the tank and didn’t seen anything, you should be good to go. I’d keep an eye on the print and if you notice this continuing, let me know so that I can get you in touch with our support team.
Out of curiosity, are you using limit switches to detect this, or Trinamic’s built in StallGuard?
No worries if you don’t want to / can’t answer, just being curious about the machine (as always)
We have several limit switches throughout the machine on various axis. You can see a few of them by pulling off the front cover The switch on the wiper specifically, times how long it takes the wiper to complete its path and then return home. If there’s a discrepancy in expected vs. actual timing, the Motors Jammed error gets thrown. Other axis run on a similar mechanism and the Motors Jammed error isn’t exclusive to obstructions with the wiper.
