2 Colour Printing Issues - HELP!

Hi All,

Hope you can help, I have an A20M (1.1.8) which has ONE Hotend and TWO Extruders (E0 and E1) - for anyone unfamiliar with this printer.

Having real issues in getting the printer to interpret the GCODE two colour file - unless I'm being really thick, I get the following problem:

a] I find a 2 colour example stl file - it has 2 clearly defined colour segments with NO graduation between the two colours
b] I load these (2) files into Cura (with A20M profile already loaded in)
c] I then assign a colour to the respective segments and merged the print
d] This I then sliced
e] Saved as GCODE ready for print
f] (only did this in case I was going mad) I then open the GCODE file in text editor and search to make sure the "M163 E1 P1.00; Set Left to 100%
M163 E0 P0.00; Set Right to 0% M164 E1; Save Mix" commands don't say anything other than either 100% on or 100% off (so either E0 or E1 are exclusively in play at any specific time) - having checked the entire file, there is absolutely NO mention of anything else (so no 50/50 commands)
g] Save this fie onto SD card and pop into A20M SD card slot
h] Select the file for print and cross fingers
I] Printer switches randomly to 50/50 throughout print resulting in something that resembles a badly printed smudge. If I'm lucky, one colour might be 100%, but the second is a 50/50 mix....

Pretty new to this perhaps, but I'm totally perplexed as to what else to do - there must ether be something wrong with 1.1.8 firmware or a command that needs to be sent to say NO DON'T MIX THE COLOURS just please print it as a solid 100%, like the GCODE told you to...

Hi, If you are referring to the need for monochrome printing,
the extruders used in each section need to be set in the setup.
If the color mixing ratio is 50/50, it is a fusion of two consumables.

If there are smears of ink on the back of your printouts, you can use an automated tool to resolve the issue.
Make sure the printer is loaded with plain white paper.
On the printer control panel, swipe the display to the left, and then touch Setup.
Touch Tools.
Swipe up on the display, and then touch Clean Page Smears.
The printer slowly feeds a blank page.
Wait for the printer to eject the blank page.
Try to print. If the print quality is unacceptable, continue to the next step to make sure you are using the appropriate paper for your print job.

Try these remedies if your printouts have improper colours: Make sure your printer software's Black/Grayscale or Grayscale settings aren't turned on. Check the nozzles on the print heads to see if any are clogged. Then, if necessary, clean the print head.
