Stepper Currents - Input Shaper Comparison

We've talked a lot about stepper currents affecting input shaper results, so I wanted to make a post that covers it specifically.

The setup:

• 300mm flying gantry
• 4040/2040 frame, 2020 Y extrusions with backers
• LDO CNC kit in AWD
• 10mm EPDM belts @20lbs
• Experimental Monolith toolhead
• LDO 2504s @36V
• Room temp

I recall 2804s having 2-3Hz lower results compared to 2504s. I'd imagine the Krakens would beat the 2504s by 2-3Hz, but those also have some other drawbacks to them in different areas. So, I think the 2504s have a good balance between torque and top speed, even at only 24V.

I did 5 runs, each after running the motor_sync: 1A, 1.5A, 2A, 2.5A, 2.8A (dumb).
