After Micro swiss DD upgrade,Extruder skips steps

Phaedrux

Yes add to config.g

0.15 seems like a very high PA value for a direct drive extruder.

@Phaedrux i have insert the lines you written.

Thats the result:

Veti

can you reduce the e steps by 10% and try again?

lui2004

@Veti no problem

with which temperature,what do you mean ?

Veti

@lui2004
any and see if that improves the stringing

lui2004

I have print by 215°C
Retract distance 1.5mm
Retract speed: 35mm/s

@Veti soo after i watch the Video and take the Profile from the Video, i have no stringing but little gaps or ooze i dont know what it is ?!

Edit: With Layer height: 0.2,215°C i have no stringing
with layer height 0.16,215°C again a lot of stringing

what cause this problem ?

After a second try with 200°C i have a lot of stringing

@lui2004

how confident are you in your e steps?

M92 X80.00 Y80.00 Z800.00 E139.19 ; set steps per mm

marlins default for the ender 5 is 93.

i have the Micro swiss Direct Drive, micro swiss gives me a start steps about 130 with 1.8 angle motor.

but since Saturday i have the E3d 0.9 Angle motor and after calibrate the Esteps i have E277.89

Veti

can you print with cura or prusaslicer?

lui2004

@Veti yes of course i have both

i try now prusa slicer alpha2

lui2004

@Veti now i have print it with Prusa slicer

the curling at the base suggests to me that you are printing to hot

@Phaedrux said in After Micro swiss DD upgrade,Extruder skips steps:

double checking your extruder calibration.

@Phaedrux Extruder was Calibrated yesterday all fine 110mm messured and 100mm was forward.

lui2004

@Veti i think i have solved it !
i have a all Metal hotend from micro swiss and it was recommended to increase temperatur 5-10°C so i have tested it with 222°C and i have no stringing just a little bit but its ok.

what i can print now to check if its all ok with my setup ?

Edit:

I have a 0.4 Nozzle which Extrusion Widht did i take ? in some how to and youtube Videos they say take EW: 0.45 another Video says take 0.48 Etrusion Widht, its a little bit confusing
