Microstepping issues causing inconsistent extrusion? Folger Tech Prusa i3 variant Getting inconsistent extrusion width on prints: [attachment 76249 20160209_043741205_iOS.jpg] [attachment 76250 20160209_043752271_iOS.jpg] I have a Folger Tech RepRap 2020 Prusa i3 Full Aluminum on Marlin firmware. I'm suspecting there's something wrong with stepper motor not moving smoothly and extruding in "steps". It's causing the infill to be pretty poor as well. And I'm worried my prints will break apart easily. Am I on the right path? How do I verify and how do I fix?

@Danikin: thanks. What is your extruder steps/mm set to?

en the LCD shows 90steps/mm
but is 900steps/mm in the firmware]]> Danikin Printing Sat, 16 Apr 2016 18:58:50 -0400 https://reprap.org/forum/read.php?262,650798,653100#msg-653100 Re: Microstepping issues causing inconsistent extrusion?

the problem was too many steps/mm. try to change it from the LCD, or in the marlin firmware.

good luck.]]> Danikin Printing Fri, 15 Apr 2016 15:08:18 -0400 https://reprap.org/forum/read.php?262,650798,652433#msg-652433 Re: Microstepping issues causing inconsistent extrusion? Folger Tech Prusa i3 variant https://reprap.org/forum/read.php?262,650798,652433#msg-652433
@bryanandaimee: nozzle is 0.4mm, layer height is 0.2mm, extrusion width is 0.5mm. I'm actually not sure how to check for the microstepping of my extruder driver, can you give me a link on best way to do so?
