RE: MK4 Current Owners - Issues? [POLL]
I have had continuous issues with the MK4. I have no interest in printing PLA so I can't speak to printing the golden scenario...Prusa PLA on a Prusa Slicer...
I need stronger, solid infill Carbon Fiber type parts and enclosures and have the upgraded hardened steel 0.4mm nozzle. I have been attempting to calibrate on a more basic specialty filament (3DXTECH PETG-CF) within the MK4 Prusa enclosure and I use the recommended NANO polymer adhesive advertised by 3DXTECH.
Issues:
- critical thermistor failure requiring replacement within the first 25 attempted prints.
- z calibration has been poor, requiring manual adjustment in prusa slicer to prevent the nozzle from scraping and accumulating petg gunk on the nozzle during prints
- complete failure to print supports correctly. This has been the main issue. For context I am talking about small rectangular box enclosures for electronics that have holes for antenna ports screws, power ports ect. These are not complicated prints. I've watched the MK4 basically attempt to print supports in mid air before my eyes. I continue to try almost every possible combination of support type, speed, flow rate, interface distance.. ect with no success.
