Re: Adjusting E-steps for the old Bondtech extruder

The old ones have different steps for left and right. It’s in the big bondtech thread, I also still have a setup from S3D at home so I can find it in a few hours

Re: Project Bondtech Extruder

That’s a good idea. I zip tied the breakout board on, wrapped in silicone, it’s working but I can’t use the back inch of the build plate. I’ve modeled an adapter that will let me keep that board in the original configuration, just need to fine tune the hole placement. I have no interest in redoing a...

Re: Project Bondtech Extruder

I just tried installing my dual direct, and it looks like it's not going to happen without a ton of rewiring, or making a new little holder for the breakout board. My breakout board doesn't fit in the bondtec little shield, and both the heater/thermocouple, and the fan wires are much to short to fit...

Re: New idea for insulating a hot end rapidly

6172T14, but the other should work just as well. I also got 88155K63 but that just wants to unravel when you look at it.

Re: Heat Shields?

When people insulate their hot ends, the wrap the top too. Common materials are Kapton polyamide, mica, ceramic, and fiberglass. All are better insulators than brass or stainless. If you want to use metal, titanium would be a good option. But you can also use some synthetic high temperature gasketin...

Re: New idea for insulating a hot end rapidly

Just wanted to build off of John's original post. The 3/4" tubing looked like it had some extra space, so I tried out 5/8", and it's nice and snug. Here's 5/8" ID silicone covered fiberglass like Jetguy mentioned earlier. Purchased from McMaster-Carr I'm not sure how it's going to hol...

And beware of the fumes from whatever adhesive is used.

Re: New idea for insulating a hot end rapidly

Typically with that sort of product it's the adhesive that has the lower temp rating. It can release gas or fail altogether at high temps. I just ordered some of the fiberglass tubing as well as the silicone coated fiberglass tubing. To try out. I have been using just high temp silicone rubber cut t...

Re: Carbon Fiber Print surface??

I ordered one of those a while back but haven't tried it out yet. I also haven't had success with hairspray though, I can't seem to find that aquanet around, but pva glue seems to wash off completely. Hairspray definitely took more than hot water to wash off, I think I used detergent and then aceton...

Re: Bondtech BMG upgrade for the N series

I haven't been using dual extrusion much. Mostly I just keep my Bowden on PLA, and I've been too busy printing production to tinker around much... but it looks like my summer project is going to be bondtech 2.0. Even though I feel like I haven't really gotten the most out of my first bondtech upgrad...

Yeah but if you're doing something that requires press fitting bearings, aligning shafts, etc... it's not such a simple task.

It's hard to argue with results especially when each go takes hours or days.

Re: Has anyone used ESUN PETG?

I was having similar troubles with XT, you may want to try glue stick at a lower temp, I'm getting best results around 45C. Success on both glass and the buildtak.

Re: Having Bed Adhesion Troubles

Yeah, I'm also thinking of figuring out how to support the part on the exterior so that a little wobble doesn't compromise the entire print. Since I'm printing a tube, even a short cylinder inside the tube can help.

Also, 20 line brim won't hurt, and it's not much more time in the grand scheme

Re: Having Bed Adhesion Troubles

That was the first thing I did. I've been printing these since I got my printer in spring. The design is absolutely unforgiving to any upward curling or overextrusion. I may be underextruding a tad, but just down enough to not get any buildup on the nozzle. And verified with a solid calibration cube...

Re: Having Bed Adhesion Troubles

The problem isn't getting plastic to stick. It's that after about a half dozen hours, adhesion goes away. In the first few hours if I remove the part the raft stays. After 6+ hours everything just loosens. And I am printing enclosed. If I can get consistent results with heavy glue at 45, then I'll t...
