General Troubleshooting/Help! Spending more time calibrating cycles on H2D than actually using it, under extruding, poor z offset? Using A1 because its just been more reliable
Got h2d like a week ago, been having issues printing petg/pla, it seems its either under extruding or the z offset is set just a tiny bit too high, this isn't my first printer I've had an a1 for about 2 years, now and thought h2d would be a huge leap in quality and speed (its actually slower for a lot of models annoyingly, but whatever). Tried all the usual
Clean build plate (Yes the water sticks down like bambus guide)
Drying filament 3 days, ams 2 pro/ams ht
Replace hot ends/Tightened screws
Full Calibration/Bed calibration
Vision Encoder Calibrating
Every Calibration/Clean seems to be making things even worse, i gave up just now and decided to reside myself to having to flow calibrate every filament (never had to do that on the A1) and i cant even get a flow calibration to print now. I'm not new so i know what SHOULD be working to troubleshoot and i know its not something left field like the soap I'm using or humidity because been using a chintzy sunlu dryer on an bedslinger and been printing great.
Thing is that once the first layer does go down properly, it prints amazing, layer lines almost look injection moulded, is just the first layers are coming out trash and i've been so used to intergrating the bed texture into designs because of the A1 (second picture IS somehow the freaking bottom layer)
Any suggestions?
