Comment on Well that's a $70 fuck up...
JackDark@lemmy.world 3 months agoFrom context, I’m guessing that there were broken parts of the print in the back, obscured by the resin. When the bed came down to start the new print, it pushed the broken parts from the last one into the screen, breaking it.

Basically exactly what happened.
I didn’t even notice the bits missing from the print as it was still being rinsed in the alcohol.
The head of one of the minis I was printing for a friend popped off and I didn’t notice before starting the second batch of dudes and then CRUNCH $70 dollars for a new part to be on the way.

Seems like the manufacturers should be able to take advantage of the stepper driver’s current sensing and stop the movement if it detects a high load before the bed is all the way down. With Trinamic drivers you can do sensorless homing using this same load sensing feature, though in your case you’d need a homing sensor to detect whether the bed actually made it all the way down.

Yeah my filament printers do sensorless homing (they’re modded to frig) and it made me really wish my resin printer could do the same but there isn’t an open source board I could swap in there (as far as I know) so I’m just going to have to keep being careful with my current resin printer.
