M569 P3 S0 Extruder motor(3) goes backwards M569 P2 S0 Z-axis motor (2) goes backwards M569 P1 S1 y-axis motor (1) goes forwards M569 P0 S1 x-axis motor (0) goes forwards generated by RepRapFirmware Configuration Tool v3.2.3 on Sun 14:42:48 GMT+0100 (Central European Standard Time) Here's my config.g Configuration file for Duet WiFi (firmware version 3) The rods are straight but bought on AliExpress. I have a 5mm aluminum bed with a 4mm mirror on top which makes the bed heavy.Ĭould the brass nuts be the pitfall here? They are not very tight. I also added an extra grub screw (triangle wise) to the belt pully to get it centered as I saw it was a bit off center when turning a revolution. I use 2 8mm lead screws, 2mm spacing, set to 400 steps/mm in config.g. The stripes are about 4mm wide and it's even. So in the middle of a print I simply turned of the heat and it made no difference over the last 60 layers, still banding or whatever it's called.

I checked out if it had something to do with the 40A SSR as I'm running a heat bed on 200 volt and the temperature is fluctuating a degree celsius intermittent over a 2-3 minute period. E3D V6 0,4 nozzle and a Bondtech original extruder. I have a Capricorn bowden tube that's 650mm. I'm using 0.2 PA and about 2 mm retraction, retract speed 100mm/50mm. I don't have these problems with other stl's only the ones from 3DLabPrint which are very large parts(printing a spitfire 1700mm wing span). It's dialed in but with those 3D lab print files with 1 perimeter 0,42 thin wall and plenty of retractions on every single layer anything can happen anytime, so I have to watch the print and dial in manually when it suddenly is getting under extrusion on layer 142 or whatever happens.
