Servo vs. Stepper - difference in sound. JMC iHSV57 vs. 2Nm stepper, Igus 10x50mm lead screw.

Interested to know how different a stepper and servo sound? I was, so I put a few clips of each together. It's nothing scientific, just something I found interesting. These machines are still in the early stages of development, made with parts on hand and frequently being swapped in and out. While this does increase noise and vibration, I prefer to keep the parts loose and easily removable. The servo is a 180w JMC iHSV with integrated driver, model iHSV57-30-18-36. The stepper in the here is a Leadshine model 57HS21A with 2.1 Nm @ 5A. The driver is an M542C. Both were powered by a 36v power supply. The servo is quite a bargain. Rated at 0.6N it easily is as powerful as the 2Nm stepper. The cost of the stepper and driver is normally around $65. The servo usually sells for $95 from G-Penny on AliExpress. While the servo's top speed is about 3x that of the stepper, steppers can be faster in reciprocating machines with better low end torque and acceleration. The top speed is currently limited by the ESP32's ability to send pulses fast enough along with other work like the Blynk IoT app. The servo should allow control without pulses, which would be a huge improvement. Additional info I've found on the iHSV57 servos regarding tuning, configuration, PC and Modbus control, software and more can be found on this link: https://github.com/MikesMachines/JMC-... Aside from the first clip of the stepper and T10x20mm lead screw, the rest use a 10mm High Helix lead screw with a 50mm lead from Igus. The screw is great, but I bought the preloaded nut because it was both the cheapest and the only one that fit the existing tube and linear bearings. I've removed as much of the preload as possible, but it's not ideal for this workload. More info on the Igus screw and nut: https://www.igus.com/info/lead-screw-...
