Problem with the filament sensor
Hello,
Yesterday I print some of "low high" object that working correctly. After I try to print a cc. 35mm height object. About 8-8,5mm height the printer always go to filament runout problem. The filament not run out from the forwarding gear - not need to unload and load again, only need to push the button twice and load it again and working correctly again for 30-40sec.
I check the wire from the sensor the motherboard, it seems all wire good, not broken. I reconnect all connector on the mainboard and clean all contact.
But is not solve the problem.
The printer update a monts ago to multi material unit, and also modify the sensor position, but earlier working correctly. I print a new side panel for the forwarding gear, but it not solve the problem. Now I using without this upgrade, I load directly the filament to the printer head with the modify sensor position.
What can be the problem, and the solution? Maybe the IR sensor are wrong? I don't thinking it, because under 8mm are working correctly, the problem appear the Z reach this height.
RE: Problem with the filament sensor
If it is related to height. If you get past that height, does it work okay again? I don't have my MMU connected yet so not sure of the difference.
My first thought is that you have a cracked conductor that only goes open circuit when it is bent to a specific angle. These can cause intermittent, hard-to-track errors. I would replace the wiring.
Cheerio,
