i am losing my mind trying to print with this blend nozzle. i have tried retraction
-lengths from 2 to 10
-speeds form 20 to 50
-temp from 190 to 215
i bought this used and the previous owner ruined the nozzle and the extruders. i have put a new nozzle and 2 new dual gear drive extruders on this.
Also
every time i do a dual print i have to edit the gcoge and remove all the M109 lines after the first one because it pauses on the print every time it changes extruders and melts a fish eye into it.
Please help me fix this.

Re: A20M dual print retraction test
well... i installed a bootloader and now i have no printer.
when i plug in the usb , windows beeps and the com port shows up in device manager as a ch340 port but cura cannot upload firmware
I also tried to flash the .Hex file with ProgISP but still no boot
Also tried Geeetech software
