I don't actually have a clear direction. I'm mostly using it as an opportunity to practice my Fusion 360 skills.abraham.m wrote: ↑Oct 15, 2018 7:11 pmI'm curious where you're going with it. If there's some interest, it would be worth making mine more pretty - so far crickets. And in use, I've just found little to nothing wrong with mine (run the filament horizontally, flexible filaments flop around a bit more).
The right way to do the tensioner is with weights. They don't care the size of the retract and the force is steady.
Uh huh. I think if I WERE to do that (my initial thought) I'd probably use one of the really smaller bearings. But my set up uses no bearing at all, and it works just fine.
I have a SMALL angle, less than 10 degrees total. What I found was if it is constrained off to one side, even if it bows the wrong way initially, it'll flip over under tension on its own.paul.m27 wrote: ↑Oct 16, 2018 1:54 pm[*] learn about the way filament behaves on the retract, iterating to get the angles right (my initial version didn't have enough of an angle, and retract actually was able to push the filament back through the spool side of the system)
I enjoy tinkering with the mechanics/design of this all. It give me an excuse to design/print things.
I found it much easier to drop the motor current when printing, increasing it during tool changes and reducing holding current.
I wonder why a simple fix like this wouldn't be implemented by the dev team, its been a pain point on the forums forever.PJR wrote: ↑Oct 18, 2018 7:40 amI found it much easier to drop the motor current when printing, increasing it during tool changes and reducing holding current.
M911 E16 ; reduce holding current in start G-code
M912 E31 ; increase running current for tool changes
M912 E24 ; reduce running current for printing - this value can be as lower - 20 also works fine (for me)
Well, the firmware and Slic3r profiles are provided and "must" work with every PR printer out there. There are some MMU2 users who have high friction feeds, so the power is high by default. Pre R3 extruder parts also required higher current
