Which Stepper-Motor should I buy

mir sind vor ner woche meine Motoren abgeschmiert, weil sie in eine ecker gerammt sind (bltouch kabel gelöst) und jetzt muss ich mir neue Motoren kaufen. Ich würde sagen ich kaufe mir einen E3D High torque für die z achse und 2 compact but powerful für die x und y achse. Irgendwelche einwände oder vorschläge was besser wäre? LG - Daniel


my motors broke a week ago because they rammed into a corner (bltouch cable unbound) and now I have to buy new motors. I would say I buy an E3D high torque for the Z-axis and 2 compact but powerful for the x and y-axis. Any suggestions that would be better? Thanks for your help - Daniel

What printer do you have, what electronics, and what stepper drivers?

I have an heavily modified Ender 3, an skr mini e3 with tmc 2208/9 not quite sure

Does it use 12V or 24V power?

it uses 24V

Both those motors are rated at 1.68A. It's usual to run stepper motors at a peak current between 60% and 85% of rated current. Above about 85% they get too hot. So for those motors, that's about 1A to 1.4A. That 1.4A is a little high for TMC2208 drivers, but possible with good cooling. Should be no problem if your drivers are TMC2209.

my drivers are tmc 2209 i looked it up in the specs, so should i buy them?

Yes, those motors should work well with TMC2209 drivers.

Sorry, "chidaoking3" was a spambot. Removed and deactivated.
