Alright, you’ve waited long enough #IGentUS is officially a plotter. Using @MISUMI_USA extrusions and @igus_Inc #Drylin bushings, it’s making lines and turning circles.

Straight lines and round circles.

Each flat of the big nut in the video is exactly 13.5 cm wide, and the circle measures 10.35cm in one direction and 10.45 cm in the other. At this stage of the build, I’ll take that kinda precision. ( 0.9% )

Hey @Mike_Miller What linear bushings are you using on the cross exterior slider. I am looking at doing the same slider method on ringrap. I would like to see what you are using.

Those are @igusInc JFM-1014-14 Drylin bushings. They’re riding on 10mm diameter igus rods that are ceramic coated, but seem to work well on other rods as well. for the perimeters, they’re using normal Ingentis parts, and teflon tape to make an interference fit. The sled was custom printed (and a V1 part)…the bushings in that case are friction fit plus superglue.

They work well with Rotational and linear friction?

So far, they work perfect…but I’m not laying plastic yet, so we’ll see about resonance and surface detail effects. I see no reason why they wouldn’t work just as well as other bronze bushing and GT2 belt printers.
