Hi Guys!
I’m new around here but i found this community great :slight_smile:
I am currently working with Zonestar P802M (Prusa i3) and I hope I can get your help with an issue i experienced. i have decided to upgrade my melzi controller board to fastbot bbp1s

The Fastbot controller runs Octoprint which is amazing but also very frustrating because there are so many advanced configuration i dont know how to configure and it damages the prints heavily. here are some things:

  1. Extruder is working “too fast” - after 1-2 minute of printing standard pla, every seconds of extrusion the extruder hiccups once (like it cannot push down the filament) and then continues until the next one
  2. the printer becomes faster as printing time continues (believe me it becomes very very scary, you could swear things will start flying in the air)
  3. there are inconsistencies with the extrusion of the PLA - most probably due to the speed of the system.
  4. the 3d printer has a size of 220x220x220 - when i put a file in the middle of the bed, it still starts 30-40% to the left

can anyone help translating the old configuration to the new one (they are based on Repetier-Firmware V0.92 and can be found here:
