Sounds like there could be something clogged in the nozzle, I would try pushing through some filament or nozzle cleaner at high temps (300c ish) to try and burn things out. General advice is never use different materials on the same nozzle, but that doesn't stop most of us.
This likely won't solve your z axis shift but it may help things. I have no experience with your printer or even brand though, so I cannot comment about whether the software or hardware may be to blame for some issues, but it sounds like there's more going on that a partially clogged nozzle.
I'm not sure if it's the Z or gunk building up and dragging. Also with the new nozzle it's been only PLA and no joy whatsoever.
Did you get the new nozzle in and issues have not changed?
correct. I initiated a return with amazon. I have had a 250g spool in the drier since about 10am today, and will try it this evening, but if that doesn't work I'm just returning it.
In trying to do a cold pull (which you do in this machine by attaching the nozzle upside down and manually pushing filament in), it was oozing and popping with the remnants of the previous filament, which to me says very wet filament?
I had tried drying filament for ~8hrs yesterday with no good results. Is there something else that could cause the oozing issue? My friend brought up that maybe the temperature sensor isn't working properly and it's hotter than it thinks it is?
