After Micro swiss DD upgrade,Extruder skips steps

[lui2004]

@Veti 210°C its PLA

@lui2004

try printing at 200 and 190 and go down and start at 1 mm retraction again.

[lui2004]

@Veti ok

You can try adding this command to your config.g M204 P500 T2000 which will maintain your current acceleration for print moves, but allow faster acceleration for travel moves. This can help a bit with oozing by shortening the time of the travel moves.

This would also be a good time to look into tuning pressure advance and double checking your extruder calibration.

3.5mm seems high for a direct drive. I would use the micro swiss recommendation of 1.5mm distance and 35mm/s speed for retraction, and then tune pressure advance. Since it's a direct drive a good starting value would be M572 D0 S0.05.

@Phaedrux i can add it somewhere in the config ?

I will recheck the extruder tommorow

I will recheck the PA value my actual value is 0.15

Thanks

[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

@lui2004

what slicer are you using?

[lui2004]

@Veti i use Simplify3d

@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

[Veti]

@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.

[lui2004]

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
