TMC autotune: help with motor specs and unknown extruder

[tverdyy]

Hey everyone,

I’m trying to get the most out of my Klipper setup and I’m interested in using the TMC autotune addon. To make it work, I need to gather some information about my stepper motors, but I’m having trouble finding the specs.

I’ve got the following motors installed:

• Z-Axis: Shengyang 42BYGH1634-A-20Db
• Bed: Shengyang 42BYGH3043-A-24DN
• X-Axis: Shengyang 42BYGH2265-A-24DN
• Extruder: Unknown model (if anyone has any tips on how to identify it, I’d appreciate the help)

To populate the motor_database.cfg file, I need to know the following values for each motor:

• Resistance (Ω)
• Inductance (mH)
• Holding torque (Ncm)
• Max current (A)
• Steps per revolution

Could anyone help me out with the specs for these Shengyang motors, or point me in the direction of a reliable source? I’d also appreciate any suggestions on how to identify my extruder motor model.

Thanks in advance for any help or guidance you can provide!

Thanks for the tip! I’ll reach out to Sovol at info@sovol3d.com and see if they can provide me with the necessary information. I’ll make sure to share the specs here in the forum once I receive them, so that others with the same motors can benefit from it. Appreciate your help!

I reached out to Sovol a while back and received these. While waiting, I tuned my motors another way, so I never really looked at them.
