Motorized filament assistance

eranglr

I have a highly fragile filament, in order to successfully print it, I came up with a stepper motor that withdraws the filament out of the spool, and directs it toward the extruder.

I have a Duet wifi + Duex 5, and the spool stepper motor is connected to D6 on the Duex.

I've tried following this, with no success.

Here is the config file:

@eranglr you can add 2 extruders to one tool

PCR

@eranglr

like M563 P0 D3:6 H1 and then make the "mixing" ratio 1:1 with M567 P0 E1.00:1.00

eranglr

@pcr I've tried both M563 P0 D0:6 and M563 P0 D0:2, with no luck.
What's more, when I try this, HEATER 1 disappears from the GUI (I've got two independent extruders on IDEX printer).

@pcr I've added 'V' axis and I manage to control the extruder by G1 V50 for example.

@eranglr said in Motorized filament assistance:

M563 P0 D0:D2

it should be M563 P0 D0:2 remove the extra D

eranglr

@jay_s_uk I don't have an extra D in the config file.
