RE-POSITIONING OF 4 EXTRUDER MOTORS
Since I had changed my cable management in a way to have all my cables in flexible carriers which did away with that wound plastic over the cables, I could not intsall the 4 extruders on top of the frame as required. I simply had to construct a bracket about 100mm rearwards and mount them on it. Luckily the cables were long enough. This however presented another problem, becasue the PTFE tubes were not long enough and I had to cut others 100mm longer. This has presented me with a problem, becasue when I load the filament, it remains unfed into the multiplexor.
I have changed all the prusa parts to alumiinium and it works like a bomb, however I have not yet printed in 4 color and have yet to try it out.
I have checked the configuratio_prusa.h file and there is a firmware command I alterd but it did not have any effect on the lenght of the loaded filament.
#define BOWDEN_LENGTH 433 //default total length for filament fast loading part; max length for extrusion is 465 mm!; this length can be adjusted in service menu
I changed the 433 into 533 but the same amount of filament was fed....
