extruder calibration issue

Hello,

I just bought my first i3 Mk3s and build it over the weekend. Everything went perfectly sofar. After a clogged nozzle and a broken pice of filament (which broke right at the bowden tube end) I had do disasample the hotend and put it all back together. Now I recalibrated my e steps and got values which are totally different but work. how could that be? Did I do something wrong? Right now I am printing with an e steps value of 282. Thanks for helping me out!

Re: extruder calibration issue

Iirc, default Esteps are 280.

Don’t calibrate esteps on the mk3. There aren’t any unknowns to calibrate. If you get answers close to the default values, you’re probably measuring noise. If you get very different numbers, you’re probably wrong.

Thank you for your reply. I am still a little confused. You are saying that default e steps are 280. I just did a factory reset and its back on 180 and vastly underextruding.

Definitely 280.
