Control Cooling Settings per each Extruder

[4truemodels]

Hello!

I believe this feature should be included ASAP. It is awful for the ones that we have 3D printers with the IDEX system (each extruder travelling and working independently, letting the inactive one in a rest-place), to NOT BEING ABLE to set up different cooling settings per each extruder.

This put a critical limit to the use of this IDEX system as you can't combine different materials propperly.
For example: if you want to combine ABS and PLA in the same part with IDEX system, you can't do that because you are forced to set up the cooling settings for one of them. Everyone knows the big difference in the fan speed settings between ABS and PLA, so being unable to set it up differently per each extruder makes it impossible to use both materials in the same print regardless having the IDEX system.

Please change the "Cooling Tab" so it works more likely the "Temperature Tab" in which you can set up different settings per each extruder.

Thank you!

Waiting for that as well!!!!

Is it possible to use a workaround by using two different print processes, one for extruder1 and the other for extruder2 ?

Same here. I have a Sigmax and I want to print PLA with PVA. PVA needs almost no Fan.

I learned through my pre configured Sigma files, generated by Sigma Progen Tool, that you can change actually exact behaviour for each extruder.
Go to FFF Settings -> Scripts -> Tool Change Script

Mine looks like this:

Code: Select all

{IF NEWTOOL=0} T0			;Start tool switch 0
{IF NEWTOOL=0} G1 F2400 E0
{IF NEWTOOL=0} M800 F35.27 S0.0046 E9.0 P1.93	;SmartPurge - Needs Firmware v01-1.2.3
;{IF NEWTOOL=0} G1 F35.27 E1.93		;Default purge value
{IF NEWTOOL=0} M106 S85		;enable fan for part material

{IF NEWTOOL=1} T1			;Start tool switch 1
{IF NEWTOOL=1} G1 F2400 E0
{IF NEWTOOL=1} M800 F42.32 S0.0415 E9.9 P2.13	;SmartPurge - Needs Firmware v01-1.2.3
;{IF NEWTOOL=1} G1 F42.32 E2.13		;Default purge
{IF NEWTOOL=1} M107		;disable fan for support material

G4 P2000				;Stabilize Hotend's pressure
G92 E0				;Zero extruder
G1 F3000 E-4.5				;Retract
G1 F[travel_speed]			;End tool switch
G91
G1 F[travel_speed] Z2
G90

I don't want to seem like a complete idiot (because I'm still working on the complete part) but does the tool change script replace the existing code? Should it be placed after the existing code or prior to it?

This is the answer I've been thinking about ever since I started using PVA and learned that cooling may be the primary difficulty I've had with it.

At the moment I can't seem to get Tool 1 Fan to turn on.. Tool 0 turns on.. but not tool 1 unless I do it thru the printers panel.. Go to Tune, then Fan2 and then its ok.. I'm not even turning on the heat to Tool 0..
