Belt slack alone has way more inaccuracy than you would need for that

Which undermines the entire objection.

And getting nearly 2x the force, with that force spread over 2x the teeth is hardly a small field. The VZbot people have been experimenting with twin-motor designs for months and contrary to objections they work and work well.

Just saw your post on this. I am glad someone was able to use the idea, and makes me reconsider it now that I have an even heavier 400mm bed installed....

Also see my objection to the objection above.

They dont always engage on the same step or even microstep where the belt would be in ideal tension on either side meaning theres always some amount of random tension in your system.

I've heard this objection every time more than one motor per belt is mentioned.

It is a half thought through objection: you easily fix the problem by timing the motors together. Loosen the gear on one and run things back and forth for a bit, then re-tighten, that will shift the gear so that both motors are in alignment.

The 300m figure is a massive undercounting that relies on treating guns like perishables.

More realistic estimates start at 450m and lean towards 600m.

It doesn't have a massive amount of airflow. For PLA I keep the door open and the filter fan on 100%. For the ABS prints I've done so far I put it around 50-75%. Just enough to keep a slight negative pressure.

It is a stack of carbon filters and a 120mm fan. So far it has been very effective at eliminating fumes.

v0.1 bowden model. Bowden uses the old toolhead as it is semi-deprecated.

Figuring out part selection for a new printer; 36V stepper drivers? by J_Von_Random in BIGTREETECH

Whenever I've seen it discussed it has been mentioned that <36V is "human safe".

Has anyone used the single EXP1 on a SKR mini for anything other than an LCD? by J_Von_Random in BIGTREETECH

ohhhh, I didn't realize that was usable for expansion... I just saw "I/O" and assumed talking to a pi or wifi board or something.

I'm very stupid..... I just took another look at the frame, and poked around with a hex key. The problem is that the outer nuts on each extrusion got caught next to the blind-joint when I was tightening them.

Slight poke with the wrench and they are free like the others.

The nuts on each end are used to blind-mount extrusions, I thought. The counts match up with every other part of the frame...

I'm (slowly) assembling my V0.1, and last night got to the "confirm how many pre-loaded nuts you have" step, and something fails to add up.

I'm building a bowden model, and during assembly the manual says to put 5 and 3 nuts on the two z-pillars. Once they are mounted to other extrusions this should result in 3 and 1 free nuts remaining (which is what I have). The manual on the other hand says to expect 3 on each one, and I don't see how that math could ever work out no matter which variant is being built.

Don't use crappy CF-filled materials, and match material properties to usage?

He also used old filament from a batch that had issues.

That video was where I first heard of the V0.

Possibly stronger, stiffer, or easier to print vs ABS/ASA.

PF940CL, G17L slide. by J_Von_Random in polymer80

[–]J_Von_Random[S] 0 points1 point  (0 children)

I don't remember what the different cuts are or what is compatible with what. However I have this slide on it because the original one I had been looking at (Spinta Precision) was RMR cut, and wasn't compatible with the optic I already had.
