Re: new A20M couple of problems

But Geeetech all metal feeder is not geared "titan" extruder, but MK8 only... Geared Titan have much better finish of walls than "direct drive" feeders of course. But CR offer for $12 dual drive feeder which is not geared, but seems good - probably with bigger current it will work good. Have it orde...

Re: Nozzle Turning Off During Print

When I was something like this problems, then already was problem with gcode (SD card removed too early), not with printer firmware alone. Check your gcode in text editor it there are not binary blocks. Possibly it could be EMC problem, so there are one easy half- and one full solution. 1. add 100nF...

Re: White text on black surface

Use laser with appropriate material coating, not 3D printer.

Re: new A20M couple of problems

I was print 4 different and at one made very hard after-print customizations of lever and extruder anti-jamming nozzle to fit.

Re: new A20M couple of problems

Extruder lever is very weak part on all Ax0M printers. Print your own with second extruder, but you need filament blocked in bad extruder otherwise you block extruder.

Re: Massiv stringing at A30M

Black plastics is most problematic one.

Try my profile for A10M, propably you need to change build size and zero position .

For PEI sheet delete line from gcode setup
G1 X12 Y5 Z0 F300 ; stop leaking hotend
otherwise your PEI sheet will have burned hole at zero position.

Re: A20m Updated model, new Heatbed with Mylar?

You need to clean hotbed with isopropyle and leave it covered against dust. It must be clean, dark black... PEI sheet is much worse.

Re: 'Singing' (and noisy) extruder

I think that it could be mechanical reason - did you tighten your printer?

Mixing sometime does crazy sounds. Try to use rubber or cork dumper between extruder and frame.

Re: Dual Print : merge color rather than pure color with extruder2

No, it is pretty fast.

10mm3/s is not 10mm/s, but 8-30x more of print speed.

Re: Z Axes step motor issue

Hmm, I look that Geetech made very good changes to original Prusa....

At your problem - I think that it is misaligned rods.
