topic_solved Setting Dual motor for Extruder
It might be a crazy stupid idea, but I wanted to try setting a dual motor configuration for my extruder. Idea is to have a strong Bondtech on the remote side of a bowden, and a very light but therefore weak cold end extruder on the platform of my delta.
This way I would have power, but also the ability to print flexible, while keeping my platform to a reasonable weight.
I'm trying to configure the board using M584 command :
M584 X0 Y1 Z2 E3: 4
It just will not work : I believe that when you do like so, you map channel 3 for E0 and channel 4 for E1. Is that so ?
Is there a work around ? Something like mapping Extruder to a dummy channel, and then mapping that dummy channel to 2 motors ? Does it make sense at all ?
Thanks for you replies,

if the extruder have the same number of steps, you can wire the motors in parallel or series.
@enggmaug do each of the extruders work by themselves? if so then what you need to do is create a tool with more than one drive:
In this case probably something like:
M563 P0 D0:1 H1 F1 ; define a Tool 0 using E0 and E1 drives, E0 heater, fan 0 mapped to fan 1
Now T0 (tool zero) has both drives assigned to it.
The next step is to set the ratio that they move. in your case 1:1
M567 P0 E1:1
At this point you will have two extruders that are both commanded to move the same amount for Tool 0. What you need to ensure is that the steps/mm of each extruder is exactly right, else they will get out of sync.
I knew I could count on you guys !
Thanks a lot, heading my way to the garage now !
It does indeed work. Thanks a lot !
