Those hybrid stepper motors can generate a fair about of torque! I used a hybrid linear/ stepper motor to push a 22lb load 600k times. So Nathan has it right imo!! You go boy! Edit: I live in Lexington, about 70 miles from Hackerspace & this is the first I've heard about it! Thinking about making the drive now! 😃👍🏻

I think I switched to vivid color profile instead of s-cinetone. I don’t color grade so it’s probably better this way Also the bigger space allows for some background separation and blurry background vs my smaller space

Have you thought about replacing each print head axis with 4 articulating arm style axis? That way each print head can reach the very center of the bed, and they can fold out of the way individually when they are not in use. It would basically be 4 SCARA arms with your rotating bed.

Very cool! I was initially very excited about your idea for a simultaneous multi-head polar printer, but when I started digging into it I found all the realities of polar motion systems. These motors aren't cheap, but if they can solve the steps vs circumference problem, I think it is definitely worth exploring.

A great video would be about building a small coreXY setup with jus a large inertial mass as print head to be placed between a printer and its table, which uses an accelerometer with a digital closed loop so that you can move the inertial mass to compensate (after low pass filter) for the accelerations generated by the printer print head motion. It should almost completely remove vibrations. Surely better than the "HULA" printer feet

Can your flywheel calculation software account for the moment of inertia? If you already have the data concerning the mass being added, I'd think it wouldn't be too hard to add the radius to which the mass is being added. Adding must mass won't mean a lot without knowing how it effects the moment of inertial of the item. Thanks for sharing what you're working on. I have my doubts on how it will work but I look forward to you proving my doubts are unfounded.

Yes, just multiply the deposited mass by the distance from the center of rotation. Mass alone is meaningless, the only thing that matters is the 2nd moment of inertia measured about the axis passing through the center of the bed.

I don't really understand the concept. I thought you talked about weight as being an issue but then you want to add a flywheel? Can't you just remove the speed of the inertia change with input shaping like code? Do you really need this benefit of a sudden stop? Is the reduction of the inertial mass by spreading it over time not acceptable? Is the force too large?
@NathanBuildsRobots

There are two issues with added mass. 1) it requires more torque to move. This can be addressed by making the plate thinner, using materials with a better strength to weight ratio, or adding a larger motor. The other issue is that rapid acceleration back and forth can set up resonance that can cause large structures to fail. The important equation is the definition of resonant frequency. (K/m)^0.5 Or the square root of stiffness over mass. Larger structures, assuming you use the same beams, like 40/20 aluminum extrusion, are both less stiff and more massive, so both factors are causing the resonant frequency to go down. Ideally you want the resonant frequency to be 2x higher than any excitation frequency. If you look at a printer filling out a rasterization pattern, the excitation frequency would be the inverse of the time in seconds between it changing directions. Usually this is around 10 hz on higher speed printers. Even with a very small/light load, resonance can cause huge problems for large structures.
