The problem with initial stellar success, is that theres’ only one way to go.
I guess this weekend will be spent with a large print trying to figure out why I have y-axis slipping, 4 hours into a print.
On an up note, it wa freakin’ SCREAMING (possibly the cause of the failure)…230% of 60 mm/s (so, you know, 140 mm/s) and the surface quality was GREAT.
At least now I have a test candidate for ascetone testing.
Looks like a nozzle catch caused missed steps shifting the print?
Yeah most likely, might need to up the reference voltage a little as well. Nothing’s getting hot, so there’s space for a little more holding power.
Your linear bearings, what are they.
They’re @igus_Inc plastic bearings. I’m having some “squirrel” issues with smaller round objects,but I can’t tell if that’s an issue with them (a possibility) or belt tension on the printer.
Get in touch if there’s something we can help you with here! (also, the acetone vapor bath looks like a fun experiment!!)
Ugh. Squirrel should be squircle or squared off circles #ThanksIPhone
Does the printer have the same setup as a ultimaker. If so do you have belts on both sides of the of the shafts. i looked at a video of a print try slowing your non printing moves. Don’t make the belts to tight rather give them some slack and fit a tensioner. The spring from a clothes peg works well.
Really? That’s surprising…I’d expect any difference in tension on each side would lead to mis-alignment of the carriage creating drag…
Are those @igus_Inc aluminum rods too?
They are. Part of their free samples program. They’re VERY good. Very smooth. I’ll say that the outer perimeter stuff has has been problem free with no lubricant. The ceramic surface is vary hard and very slick. I didn’t have any problems cutting them to length, but I did have a lathe…if you do a little math ahead of time, getting @igus_Inc to cut to length is a good way to go.
@Mike_Miller Try adding some Z lift. I occasionally had axis shifts due to nozzle drag. Z lift seems to work very good on the belt driven Z.
I will, there’s .3 mm now, but I’ll go higher.
