2 Colour Printing Issues - HELP!
Posted: Sun Nov 17, 2019 3:58 am
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...
