After Micro swiss DD upgrade,Extruder skips steps
-
is it heating up fast enough? then you dont need to change it.
i use these.

i have strange temperature printing pla with 250°C or is it the thermistor that make problems ?
-
what do you mean strange temperature.
pla does not normally need 250c to print
-
i know, usually i print with 200-205°C
you think is a thermistor problem or i need a new heater cartridge ?
i have remake pid tuning ,still the same i can print pla only with min. 250°C

pid tuning does not change the reported temperature.
this is an indication of a wrong configuration.
which thermistor are you using at the moment and what is your config line for it?
-
I have this :
M308 S1 P"e0temp" Y"thermistor" T100000 B3950 ; configure sensor 1 as thermistor on pin e0temp M950 H1 C"e0heat" T1 ; create nozzle heater output on e0heat and map it to sensor 1 M143 H1 S300 ; set temperature limit for heater 1 to 300C M307 H1 B0 S1.00NTC-Thermistor 100 K 3950
Thermistor Cartridge: Size: 1.25mmx2.0mm glass bead High accuracy: 1% Resistance value at 25°C=100K Wiring length: 1m / 39.3" Operating temperature range: -40 ° C + 300 ° C Rated power: 45MW -
yeah that is why i dont like B3950 thermistors. the reported temperature can be way off.
-
@Veti so the Problem is the thermistor?
So i will wait the New one
-
most likely yes.
-
i have installed the new thermistor but i can print pla with 235°C i dont now why
-
@lui2004
its not uncommon for the 3950 to be off by 20Cdid you change the beta and C value?
-
i have installed the Semitec 104GT-2 today
my config for this :
M308 S1 P"e0temp" Y"thermistor" T100000 B4725 C7.06e-8 ; configure sensor 1 as thermistor on pin e0temp M950 H1 C"e0heat" T1 ; create nozzle heater output on e0heat and map it to sensor 1 M143 H1 S280 ; set temperature limit for heater 1 to 300C M307 H1 B0 S1.00 -
thats the thermistor: 104NT-4-R025H42G Semitec Thermistor 100K - NTC
i checked the datasheet and the B Value seems to be: 4267 ?

B and C change the algorithm to steinhart hart. its more accurate.
see the table
-
the config is also ok like that ?
-
yes, but its still strange that you need 235 to print pla.
do you have a steel nozzle?
-
yes, hardened steel with Micro Swiss all metal hotend
-
@lui2004 ]
ok steel nozzle a very bad for printing pla. the thermal transfer is very low.
unless you are printing abrasive materials, a brass nozzle is a lot better.
or if you want a much better nozzle, there are copper plated nozzles

i print only PLA and Petg
-
then there is no need for a steel nozzle
