Only with small objects and not with the Multimaterial hotend. I’d be interested to see how it goes with the multi hotend given the hotends internal construction. The high tolerance tube should work well for this filament, but with a multi material hotend? Hmm . If you’ve got some, perhaps best to leave that experiment for after your printer is tuned right. From those pictures there’s still some work to do so. I’ll have a play with your gcode and stl when I get to the office in a few hours.
In the mean time. How’d you go? Find any slop? Loose hotend, belts, wheels? X axis not perpendicular to y?
