Love to see the new build Myles! I dont know why TH-cam didn't suggest this video when you released it! clearly I needed to hit that bell button! Its great to see the Root controller in action! I guess I need to send you another one soon with all these projects!
Stepper motors are not amazingly precise when micro-stepping. What you can do is add a reduction ratio, especially with the motor short-belt that you made. You can add a larger-diameter pulley on the rod, and keep the smaller one on the motor. That way, the motor will need to rotate more times in order to move the same amount on the XY and you can rely less on micro-stepping giving you precision.
Great suggestion! That would be a pretty easy swap over and will definitely consider this! I’m curious on the ability of motors and will upgrade if too many issues. Great advice 🤩🤩
With modern drivers, they're quite accurate as long as you don't have high load (high moving mass and/or acceleration) against the limited and nonconstant holding torque. TMCs are not like old A4988 and similar.
great project man! I've been considering building one of those for a while if you really want to go over the top with this thing, tou should consider cycloidal drives for your steepers. close to zero backlash + some reduction ratio to avoid microstep issues. is it worth the effort? not so sure, but i think would be hella fun xD and klipper of course!
When you were testing the speeds you said that there is some kind of restriction holding it back and thats correct. Most machines/firmwares have an extra parameter called acceleration. Maybe check if your firmware has that aswell and set a higher acceleration when running higher speeds.
2d bed slingers can add many static print heads for many times faster prints. use two scotch yokes to move the print bed in 2d, its more rigid than the two point beam axle mechanism. well if you want to keep the print bed static, then just use the same 2d mechanism to move a bunch of print heads at once. 2d sling print bed is just two axial rigid screws. on rails. also screw movement is a gear down ratio for high speed motors, like stepper motors. yep no belts, just two screw linear xy drives. actually, it can be fully xyz screw linear drives only. for both print bed movement or just print head plane movement. assume that the print head tool is socketed to the control point of the 2d or 3d scotch yoke intersection point. also each axis movement is controlled by one screw only, not multiple motors. preventing tilting or out of sync situations. at least the xy print bed movements are one-screw fully supported, even if the vertical print head level is using 2/4 level screws not just one. one the vertical print head axis controlled by one screw without sagging on sides, would be like an elevator with 8-point cube corner point rollers on the rails. wireless? you could use the rails as power and signal rails. just like power line lan adapters. yes the Z-axis is like a high tonnage press linear screw rail mounting. xy system being mounted in the z-rails movement mount system in the rails.
Awesome info! Thanks for this - the scotch yokes look like a fantastic mechanism for this build! I hear what you’re saying about screw driven over belt, however curious to see how the belts will respond over time… maybe I’m just delaying the inevitable! 😆😆
Look Great, exept im not a fan of closed loop belt to drive the belt, i think you create more backslash and vibration with this thing, my experience in CoreXY ( 2 Machine ) is....K.I.S.S.....keep it simple stupid...advantage with Klipper you can add sensor to check and correct the over mouvement in change of direction, we see this on yours paper at each corner. Not fan to your pen support, far from the head and with the "spring" , im sure you got lot of vibration there, try to put accelometer sensor on it. I take note of some of your idea and This give me the tempation to play with servo, i never try yet i keep my eye open for your next video

Haha! All good Pete 😂 hopefully have the next video released in 3 weeks 👍 loving the root controllers 👌👌

Cool video!!

Oh sweet!! This would be awesome! I’m always up for so crazy experimentation 😂😂🤩

I will definitely check out - I did rush the fine tuning to get up and running and may have missed this! Great suggestion 🤩🤩
Interested in the pen/servo/compliant machanism. would you share pictures/details?
I haven’t uploaded files yet, however it’s very similar to the v1engineering pen holder for the MPCNC - this is available on printables I think!
I was wondering waht type of plastic did you use for the 3D printed parts ?
Probably something like ABS or ASA
I’ve just used PLA for prototyping 🤩 however I think ASA would be a much more suitable material!
@@NEWTechCreative Thanks for your reply, on video those pieces look great, almost like Carbon Fiber that's why I was curious.
@@jmsfer I think it was printed with matte black filament… has a real nice finish 😄

@@NEWTechCreative I wonder if super fast drone motors would make the screw fly fast.
@@gsestream now that would be incredible to see!! 🤩🤩

We shall see!! Yes I agree, plenty more space for improvements 🤩 klipper would be pretty sweet to dial in the machine - great advice 👍
Bro i dont watch your full video because of your bad lightning
lol
