You can use this profile: https://github.com/roguecode/CrealityCR ... y3DProfile
Download the .fff file and import with File > Import FFF profile.
Then do the dual extrusion wizard in S3D with it and then it should work. In the print preview, on the left side change the video to view the active toolhead. Make sure the preview shows two different colors (i.e. toolheads).
Does anyone else have trouble with that above FFF Profile. Seems to send out the gcode fine, but at the start of the print it seems to retract way to much filament (during the first tool change) to start the print off correct? If I open the gcode it reads to extend out 25mm of filament, then goes into a tool change prior to starting the print which somehow retracts tool 0 filament 90mm. Since tool 0 has already been primed I am very confused to why it retracts tool 0 filament to start the print.
I am having a similar issue, though not exactly. My test print came out fine, out of the box (though not spectacular). I imported the FFF (profile) as recommended from GitHub. Once loaded, I actually tried to use Extruder 2 (T1) to print my supports, using HIPS. Unfortunately, when the script kicks off, things go awry. When the target temps are reached, the axes zero out. Extruder 1 feeds in the 90mm of filament, then spits out a prime blob of 25mm. Then it moves to the starting point of the print. Here's where things get jinky: E0 RETRACT THE 90mm OF FILAMENT, JUST BEFORE STARTING TO PRINT!!! I don't get it. I'm not very familiar with Gcode, but I have a feeling I'm about to learn...
Why is my CR-X retracting 90mm immediately prior to starting a print? It is my understanding that the code is anticipating that the filament is at the zero point (retracted 90mm), upon beginning the Gcode starting script; hence the 90mm feed, immediately after homing the axes. What I don't get is the 90mm retraction. Reading the code, I thought I had located the retraction, and commented out the line (to no avail). E0 retracted, anyway. I would REALLY appreciate a hand on this. This is rendering a $700 printer virtually useless...
A little guidance, please (I've already submitted a trouble ticket, on this)?
