So, I think I figured it out:
C is the control
1 is representative of my initial attempt
2 is the same as the initial attempt with quality filament
3 is my first attempt with Orca Slicer instead of Studio
4 when I realized what was happening…
So, the first color isn’t warping during the print, it isn’t until the second color is added and printing begins that the new color deforms the original. Part cooling turns off with the pause command and the extruder moves back to the trash chute. Once the new filament is added, I click resume and printing resumes. However, part cooling does not instantly turn back on. It prints several (varying amount of??) layers before cooling turns back on. Sometimes it turns back on quickly, sometimes it does not. You can see the layer line in 1, 2, & 3 when the cooling kicks back on and the print “autocorrects” its size. In print 4, I reloaded the filament and immediately restarted the fans upon printing using the Handy app.
As an aside, I did attempt this
G28 X Y
M106 P2 S100
to try to immediately start the fans after homing, but this didn’t work. I just jacked the M106 command from somewhere in the initialization gcode that was commented “turn on the big fan” so I have no idea if that is even right.
Here is a closer look at 3 and 4:
There is a tiny bit of a lip on the new color in block 4, but I am happy enough with this result. There is a little droop in the over hang on the X, but it isn’t very noticeable on the print when holding it. Not sure if I still maybe have a slight cooling issue going on… regardless, I think the cause of the deformation is figured out.
Anyone know what might be going on with the fan situation, or any suggestions on better code to add to start the fans after a pause like that?
Also, thanks so much for all of the support, I feel kinda bad for not noticing the fan behavior earlier.
