Hi There
I'm new to the A20T, but not new to printers generally, however I'm stumped as to how to prevent the A20T from defaulting to mixing colours. I haven't even loaded filament into the second and third extruders but on every print it starts trying to use them and the print fails.
When the prints start running the screen shows Mx33;33;33 and even if I quickly change that to 100,0,0 it still continues trying to print with all three.
Can anyone tell me how to use a single filament by default?
Thanks in advance

Hi,

it can be done by the Mixer function of the A20t but I find it kinda difficult to set. So I recommend using virtual extruders in your Slicer software and define the mix for each of them. I use Cura, but this should be possible with any other common slicer software too.

Code: Select all

; Start Code Virtual Extruder 0

M163 S0 P1.00 ; 100% physical extruder 0
M163 S1 P0.00 ; 0% physical extruder 1
M163 S2 P0.00 ; 0% physical extruder 2
M164 S0 ; Save mix to virtual Extruder 0

For the other virtual extruders rince and repeat, just set S1 or S2 to 100% and the rest to 0%.

With this you can even define virtual extruders which mix colors. Just keep the total percentage at 100%.

Then assign the virtual extruders to the STLs within your slicer project and you should be good to go.

Be aware that with a single nozzle you have to purge and wipe material from it to change colors, either by a purge bucket or a prime tower.

Best regards,
Kash

Hi I wanted to know how I could set up a purge tower on easyprint life Beta If you can help me write me.
THANK YOU.
