UM2 homemade, feeder goes double speed...

[mcmarkus 0]

Hi,

after 2 years with my original UM2, I've made a clone.

Now I'm facing a strange issue with the feeder.

The feeder motor goes double speed, to print I need to reduce Material Flow down to 50%, otherwise it clicks continuously. I've tried with another stepper, with no results.

Does anybody suggest me something?

thanks,

Marco.

Maybe your motor it's 1.8 degress 200step revolution. Um2 feeder motor it's 0.9 400steps/rev

Yes! You're completely right!

I figured something similar. I did not know the steppers were different, so I've used the same type for all of them.

Thank you very much,

Marco.
