@BoA my extruder Setup:

Original Bondtech BMG with a E3d Volcano with 0.4 mm micro swiss nozzle and titan heatbreak. 40W Heater and Thermistor 100K
0.9° Pancake Stepper

bedheater: 220V AC1.2 kW Keenovo Silicone Pad 400x400

Response: Extruder 0 has no Filament Sensor

BoA

@Frederik BMG with 0.9 stepper + 16 microsteps should have 830steps/mm

Frederik

i will try it. on moment

BoA

@Frederik Paste Your config.g only and result of

this section is still in your config twice

Frederik

config (1).g

wow, i dont know why its doubling these lines ?!?

Frederik

in my normal config. in DWC there is this section only once

BoA

@Frederik drag and drop file instead of copy paste content

Frederik

ok.
i restartet my DWC and now it looks good i think

i get always the error M591 no pin name given.

do i have to use the m950 command befor to create a pin ?

BoA

@Frederik M591 D0 P5 P"io3.in" R40:120 E3.0 S1 should be
M591 D0 P5 C"io3.in" R40:120 E3.0 S1

Frederik

WOW, Thank You soooo much.

Now my Z Axis working almost spot on...only minor adjustments needed.

Your Tip with the Extruder E steps was perfekt.

now there is only the error message from the filament Sensor ,

and i have to try if the auto bed leveling with the 3 independet z motors will work as expected with my BLTouch.

What Slicer do you use or recommend ?

I tried
Cura 4.8.0 and Prusaslicer .

Simplyfy 3d looks also realy nice, but i cant find a demmo version or similar. Its a hefty Price Tag for a Slicer and when i am reading the reviews on the internet ,i dont know if it is good at the moment with 4.1 or should i wait till the new update is released ?

Frederik

@BoA Thank YOU
