Ironically haven't changed any wiring after it was working fine, just the firmware is a completely new one so it's still getting setup. The prusa calculator and all the other things just confuse the hell out of me..

I think I might have it, I think the steps per unit for Z were stupidly off.. Everything official is telling me 4000, the calculator telling me 2560, but all the forums saying 394...

Seems like 394 did the trick lol or close too it, just fine tuning now.

I often forget that there is a tonne of controls in the LCD panel, I barely even look at it because Im punching in commands to pronterface... But yeah I adjusted the E steps and the Z steps and she is printing again... This prusa has been the only pain the ass printer i've built. I swear im sticking to kossels if I can't get this sorte haha.. they are so easy to calibrate compared to this, or at least to the point where the prints are A1.

Anyone who is ever on Ebay and sees those $390 clear acrylic prusa printers.. and you think to yourself.. hmm maybe.. could it be any good for $390?? 1.75mm, 0.4mm nozzle, 20x20x20....

Well, a year later and it's cost alot more than that. A new extruder (didn't skimp, got a merlin Hexagonal) (as they sent 3mm with the kit!! ) their hotend assembly was so cheap it broke in 5 minutes of printing, printed a new geared extruder... bought new hobbed gears, new steppers etc..

Never by anything with "Sintron" or "Aurora" in the title.
