Q: Is your PLA bone dry? I have seen similar kinds of artifacts caused by bubbling (i.e. a steam pocket essentially) coming out of the nozzle. I don't know about your weather, but up here in western NY it's been ridiculously wet for weeks.

Interesting. Got an pics of how you supported this?

Very clean and nice. Excellent job!

I think I may have been unclear in that last post. My understanding of the issue was that tensioning the standard timing belts imposed a high stress on the motor shaft. In my last post I talked about the metal belts as a possibly remedy, but acknowledged it would require a major redesign to...

@shiftingtech here's what Dymco said So yes, it will absolutely need larger size pulleys exactly as you note. I don't see that as an absolute death knell to using this type of belt / pulley / sprocket configuration in 3D printers per se, but certainly not in the current design paradigm that are...

Makes sense. I just pinged them for data on that, as I could not readily find this on their site. When I hear back, I'll post what they say. Gauge is likely the primary determining factor, and even a very thin hardened stainless belt would still have a pretty high tensile strength in comparison...

I'm coming to this conclusion as well. It is not designed to be that way, and making it that way is not really feasible. It would be less effort to begin with that design in mind from the git-go, and I believe this is the tack I will end up taking. I think the Voron project is a fantastic...

heh, who knew! https://dymcosteelbelt.com/new-products-2/stainless-steel-belts/timing-belts-2/

Interesting. I went and looked at RatRig's site - cool intro on the landing page. So the issue is belt stretch I assume? Any thoughts of using something like perforated steel banding and pulley/sprocket hybrid wheels for the motion system rather than toothed belts and pulleys? I recently got...

Aha! So the Stacker is not a CoreXY - learn something everyday. So this method is far superior to a Cartesian system like the Stacker. Cool, thanks for your message.

Greetings Voronians, I'm in investigation mode, and have not built a Voron yet. I'm examining the (really fantastic) Trident CAD model, as I prefer the bed to move in Z vs the XY gantry system. If/when I build a Voron, it will most likely be the Trident. I'm curious about the design decision to...

really gorgeous model - came into solidworks 2024 very cleanly. definitely hat's off to the folks that produced this model. A+.

I found the trident assy as a step file on github, so I'll examine that before I ask any more questions about feasibility of reversing the gantry assy. If anyone else has done this, please chime in though. Thanks everyone

Hi Claudermilk, thanks for responding. If the gantry assembly was to be installed rotated 180 degrees inside the cage frame, such that the extruder assembly was naturally in the back, would this still create the issue you speak of? Or would this cause a bunch of other issues? I'm trying to...

as a first step to try, maybe slowing it down would be a good idea so the filament has a chance to get heated enough. I don't use your slicer (I use S3D), but I'm guessing 'top solid' is the param here. maybe match first layer speed (30mm/s) and see what that does. So many params is like trying...
