I bought a Vertex Delta at Christmas time and have only managed about 4 decent prints with it. I built it myself and it worked perfectly printing the keychain and the PLA feed at the top of the printer, since then I’ve managed a couple of other things but few and far between.
Every time I print I try the calibration and 90% of the time the head crashes into the bed, I’ve replaced the build tank 4 times and trimmed it off. I’ve tensioned the belts and cleaned the printer head. Still the same result.
The printer head has chipped and gouged the printer bed.
It’s terribly frustrating; do you have any pointers on what I might need to do. At this point I’m about to replace the belts and strip the printer down and re-build it. I’m not convinced the piece sensors are working.
Do I need to reload the firmware? At the moment, apart from stripping it down and rebuilding it, I’m out of ideas.
