I had the machine configured for the dual extruder only. Everything worked fine, but every time I would click Print, I would get an error saying that communication had been lost due to a loss of power or an unplugged USB cable, which was odd, because it had no problem sending temperature information back and forth. I’m sure this was some setting I was missing, but it was enough for me to uninstall the dual for the time being. I have some prints that will work with a single extruder that I need to get done. I’ll have to reinstall and try again this weekend.
I’ll have to try this code swap. I didn’t know about this method. Maybe that will get me past the communication error.
On a somewhat related note, maybe someone can give me a hint on what I believe is a filament issue.
For my first support material print, I used a combination of the ABS/ABS and PLA/PVA settings to come up with a ABS/PVA setting. I used the recommended settings for the support. I wound up with a lot of sag and bulge in the lower half of my print, which went up straight a short distance and the went out to a wider diameter with a small straight horizontal stretch and then a filleted horizontal stretch before going vertical again (picture the lower part of the head on a LEGO minifigure). It seems to me that the ABS was not maintaining its shape and sagging out into the gap between it and the PVA.
After reading some posts on this forum, I changed the support gaps to 0 and increased the infill to 100%. I wound up cancelling very quickly, because the PVA appeared to be priting over the first layer of ABS, instead of jumping over it, and mounding up in areas, causing the extruder to increasingly move up and down as it traveled over the mounded filament. This is when I decided to pull the dual and go back to the single to get some work done.
I’m new enough to this that I don’t really know if this is a settings issue, a filament issue, or something like having the nozzles too low to the bed. I could get doubled-up paper underneath each tip, but they were a little tighter to the paper than I normally set the single extruder. I know pictures would help, but I didn’t think to take any at the time.
Based on this description though, does anyone have any suggestions"?
Thank you in advance.
