+10 on that one ^
If other materials have a bit of stringing - I’ll live with it - but if a nylon part has a lot of strings it’s basically ruined! (esp internal features)
@Phil_Hord I put the masonite board on last night, started printing, realized I’ve been lazy and haven’t put the necessary springs in place for my “Z screw” nuts (somehow wasn’t a problem until now).
I use Z-lift because I have a bowden setup and Z-lift solves a LOT of oozing / blobbing issues. The carriage wasn’t lowering back down correctly and so although I set my Z height fairly well, after the first travel move it was cactus! It was harder to see this happening on the painters tape but the masonite somehow highlighed this fact… Put springs in and hopefully now the masonite will make all the difference.
My pieces are super-smooth, do you just leave them smooth or do you need to rough them up with some sandpaper?
I don’t rough them up at all. I print on the smooth side – smooth as glass – because parts don’t stick as well on the rough side. Here’s a gallery of materials I tried: missing/deleted image from Google+
I use 20 mm/s and 1mm for ABS. I’m using 2 or 3mm for Nylon. I could do more, I guess, but this seems to have worked ok for me.
@Jarred_Baines I removed my bed springs a long time ago. Too much trouble to keep things level. But I have a Prusa Mendel, and head crashes into a hard bed aren’t so bad because the head pops easily off the X-axis rods if that happens. Not that that happens often, and when it does, I don’t think a springy bed would have helped in any case.
