After Micro swiss DD upgrade,Extruder skips steps

@lui2004 said in After Micro swiss DD upgrade,Extruder skips steps:

you wrote somthing about 800 steps

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.

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:

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

@Veti

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

increase the retraction distance until the stringing stops

lui2004

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?

Veti

print this
https://www.thingiverse.com/thing:2563909

until you get no stringing.

stay with that retraction speed for now

lui2004

@Veti which max distance i should 2.0 or 2.5 ?

Veti

@lui2004

go up in 0.25 increments until the stringing stops

lui2004

ok mate thanks

i still print the restraction stl

lui2004

@Veti i am now retraction distance of 3,5mm at stringing is always on prints

is 3.5mm to much for direct drive ?

did you change the thermistor when you switched to the micro swiss?
Are you sure B3950 is correct?

lui2004

@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 ?

Veti

what temperature are you printing at? what material?

lui2004

@Veti 210°C its PLA

Veti

@lui2004

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