Resolution will vary with you success at the head settings and minimization of variability with these units and materials. Not only do we see software issues both with the open source slic3r and the Proprietary AutoMaker but we also see some issues with print bed warping, excessive head movements or slippage in the x/y belts. Even loose lock nuts that allow some axis movement in small diameters. Often the fixes for this is to disassemble your unit and or “glue” down such components.
The sacrifice for speed is accuracy and accuracy is dependent on your particular units ability to maintain settings and or minimize these issues.
While the current layout and plan does look to support a second head, second reel and SW Support for additional materials/colors this is still likely a long way off from a “Finished” dual material dual head/dual feed machine.
I’m sure you would be welcome to test and spends moths of trial and errors as we have!
lol
From many models units I have tested, printed and worked with this is a consistent theme with any FFD machines.
Nothing prints at the edge of the highest resolutions in dual heads/materials and does it right, every print, every time much less out of the box.
You have so many variables that are not in control by you. Material dryness, temp, humidity, filament diameter etc. Much less the hundreds of settings for TWO materials with different skip rates, temps for heads and the accuracy of the two interfaces for supports etc.
Lots of worries.
There have been a lot of changes since the first production, Ed has had a few issues as he describes but I haven’t seen those on many machines even from the same batch as Ed’s unit.
