I have contacted support but while waiting to hear back thought I’d see if anyone else has experienced this issue. I searched the forum and didn’t see anything.
Here’s the issue, about 2/3 of the way through a print I heard a grinding noise briefly as the build plate was lowering back towards the resin, but then it stopped where the print was about 2cm above the resin. And the printer continued to act like it was printing except now layers were being added due to the print being out of the resin tray.
I aborted the print, adjusted the model, re-uploaded and began another print. Same issue. No idea what’s going on.
I’m printing the test print now but I don’t think it’s tall enough to encounter the issue when I did.
Yes I was wondering about the motor skipping. The spindle is clear, clean and well lubricated. That of course doesn’t rule out an issue with motor, but with spindle clear I wondered what would cause it to skip there.
This printer is a little over year old and has been used maybe a dozen times.
The issue has been resolved. Here’s what fixed it. I removed the model from PreForm, closed and re-opened PreForm then imported the model again, auto generated supported, and uploaded to the printer.
It seems to have been an issue with the code sent to the printer that was causing the issue.
