Re: Bracket/Fix for N2 Rotating Z-Axis Ball Nuts

I don't believe my design costs any build height, as it doesn't hang any lower than the screws in the ball nut. Also, this needs to be free to move slightly in both X and Y, so a simple pivot isn't the same, although there are certainly other ways to skin this cat.

Re: Engineering plastic filament

Forum member mhayduk has printed with it. I recall that it was a struggle. Don't know where he ended up with the stuff. I have a couple samples, but have never tried printing with it. You might try messaging mhayduk (Matt) to see what his experience was.

Re: Bracket/Fix for N2 Rotating Z-Axis Ball Nuts

If the flats are a press-fit on the ball-nuts, then why bolt them in place at all? Why not just open up the holes for the top of the holding bolts, and press the piece on to the ball-huts from the top? Zero clearance is not much of a press fit. It's a very light press and wouldn't expect it to hang...

Re: Misalignment left/right extruder

Doesn't the preview always show it as aligned? If you set a corrected value the preview would do what? Show it as misaligned? You measure the misalignment on your print or the actual offset of the extruders and enter that value. Correct - the Preview assumes the alignment is correct. The trick is g...

Re: Misalignment left/right extruder

In Ideamaker under the Printer Type settings there are offset values for the second extruder. You need to tweak those values until the output from the left and right nozzles lines up.

Re: Bracket/Fix for N2 Rotating Z-Axis Ball Nuts

Thanks. I normally use PTC Creo for modeling and also like Creo for exporting STL files - I have access via the day job. I don't do anything tricky, but I model parts around the system datum planes. Maybe that makes a difference. I saw the flat-bar solution after I had started on this design. I'm su...

Bracket/Fix for N2 Rotating Z-Axis Ball Nuts

This is a bracket I designed that prevents the ball nuts from rotating, but does not restrict the lateral movement required on these printers. This should result in smoother walls on printed parts, especially when using some z-hop where I have seen the ball nuts rotate inconsistently. I printed mine...

Re: Noisy rotating bed brackets due to play

I am working on a printed fix for ball-nut rotation that will not constrain lateral translation. I bungled the first print with a typo on a dimension, but should be able to mount the parts this evening and will share the STL if it works out well. http://forum.raise3d.com/viewtopic.php?f=4&t=8421...

Re: First day, worst case ... injury

When I started in this 3D printing stuff the trash can in my office looked like a murder scene as it was filled with bloody paper towels. I was always cutting myself.

Re: Drying filament under vacuum

I use a vacuum pump and a chamber on a heat plate set to 50c to dry my Nylon, 15micron is more than enough, I only get down to maybe 50,000micron. Works well. I also line the bottom of the chamber with Silica beads so the moisture has somewhere to go. Although I'm not sure how necessary that is. I'...

Drying filament under vacuum

I really dislike having to dry filament in the kitchen oven for hours and hours. At the day job I work some with vacuum chambers. I poked around the www a bit but didn’t find much information about folks using vacuum chambers to dry filament. I’m going to give it a shot. I ordered a 3 gallon vacuum ...

Re: N2 Junk

Sounds like you have installed the new cable in the wrong direction on one end. Did you press in the connectors yourself? Or maybe not. But something is off for sure. I had thought of maybe a wiring issue, but if leads were reversed it wouldn't have started the print. The print started OK and then ...
