After Micro swiss DD upgrade,Extruder skips steps

@lui2004 said in After Micro swiss DD upgrade,Extruder skips steps:
is it more accurate for extruder to make x128 ?
In some very specific cases where there is very small amounts of extrusion it can help, but in normal cases, no. Stick with x16 and interpolation. Using a 0.9 degree motor and a geared extruder should already get you up to around 800 steps per mm which is a lot of resolution without even changing microsteps which aren't as accurate anyway.
-
@Phaedrux my E-Steps is : E137.78 and for the new Steper that i order the E-Step is Double also 275.56, make somthing wrong ? you wrote somthing about 800 steps
-
800 steps are for 0.9 + bmg extruder.
i would suggest that you start with x16.
print a benchy
change to x128 and print the same benchy with the same filament and same settings.
compare the print and decide for yourself if the print quality has increased. -

it was just an example, sorry for the confusion.
For what it's worth, I use x64 microstepping on my Ender 3 to get the steps per mm up a bit on the stock extruder.

@Phaedrux no problem
I have mount today the New stepper and the prints looks a lot better.
I got a free runout filament sensor and i have connect it on E0 stop but i dont know how to make the M591 for RepRapFirmware for Duet 2 WiFi/Ethernet 3.1.1 (2020-05-19b2)
Ps: i got it i must switch the Red and Black wire
Thanks

ok thanks i have install it with success !
i connected on E0_stop and insert M591 in my config like this:
;Filament Sensors
M591 D0 P2 C"!e0_stop" S1 ;Extruder 1(0) -
Last question
I want convert the x axis with linear rails mgn12 bit i dont found nothing for mounting for micro swiss direct drive, anyone habe a link to stl file?
Thanks in advance

after i have changed the steppermotor this is my first benchy
i have a lot of stringingmy benchy:

increase the retraction distance until the stringing stops
-
The retraction speed is ok ?
In the manual of micro swiss direct drive os wrotten maximum distance 1.5 and max speed 35 ,can i go higher without Problems?
-
print this
https://www.thingiverse.com/thing:2563909until you get no stringing.
stay with that retraction speed for now
-
@Veti which max distance i should 2.0 or 2.5 ?
-
go up in 0.25 increments until the stringing stops
-
ok mate thanks
i still print the restraction stl
-
@Veti i am now retraction distance of 3,5mm at stringing is always on prints
is 3.5mm to much for direct drive ?

M308 S1 P"e0temp" Y"thermistor" T100000 B3950 ; configure sensor 1 as thermistor on pin e0temp
did you change the thermistor when you switched to the micro swiss?
Are you sure B3950 is correct? -
@Veti yes i have changed it like in the docu like this:
i have changed only the bed its a silicon bed with 100k NTC3950

@Veti i have checked the marlin source and there is for hotend thermistor:
100k thermistor - best choice for EPCOS 100k (4.7k pullup)
is config correct ?
