@Phaedrux Titan Aero Extruder on a Dbot frame, .5mm e3d nozzle at .35 layer height. Let me know if any more info is needed

your thermistor configuration is wrong. B4138 is the default.
but that should not cause layer shifts. -
@Veti if it works is it wrong? i dont ever have temp issues.
-
@Turbo
you might be printing at the wrong temperature. -
@Veti what would be the correct value?
-
@Turbo
what is the exact type of thermistor you have? -
@Veti the one that comes with the e3d v6 ecosystem of hotends. nothing special.
Seems to be 104gt from google results -
if its a genuine e3d then its B4725 C7.06e-8
-
@Veti so would the code just look like...?
M305 P1 T100000 B4725 C7.06e-8 R4700 ; Set thermistor + ADC parameters for heater 1also what about the bed heater? its a keenovo assembly
-
in rrf2 yes
-
@Veti newbie question but how can i tell if i have rrf2 or not? thats the code on the printer in question, and this is the code on my other printer. Different M commands
M308 S0 P"bedtemp" Y"thermistor" T100000 B4725 C7.06e-8 ; configure sensor 0 as thermistor on pin bedtemp M950 H0 C"bedheat" T0 ; create bed heater output on bedheat and map it to sensor 0 M143 H0 S120 ; set temperature limit for heater 0 to 120C M307 H0 B0 S1.00 ; disable bang-bang mode for the bed heater and set PWM limit M140 H0 ; map heated bed to heater 0 M308 S1 P"e0temp" Y"thermistor" T100000 B3988 ; 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 280C M307 H1 B0 S1.00 ; disable bang-bang mode for heater and set PWM limitalso i now realize i have the bed therm for this config set as an e3d therm and not the actual one. i think theyre backwards.

@Turbo said in Identical artifacts/issues on two parts on the same print job:
M906 X1000 Y1000 Z1000 E850:850 I50 ; Set motor currents (mA) and motor idle factor in percent
what motors have you got?
-
FIRMWARE_NAME: RepRapFirmware for Duet 2 WiFi/Ethernet FIRMWARE_VERSION: 2.05.1 ELECTRONICS: Duet WiFi 1.02 or later FIRMWARE_DATE: 2020-02-09b1 -
so you are on rrf2 here.
-
@Veti mototrs are part no 17hs19-2004s1.
I dont think theyre the culprit because i have had good prints before with them. The printer sat for 6 months or so so i came back to a bunch or random issues and not remembering much about the printer -
@Turbo said in Identical artifacts/issues on two parts on the same print job:
17hs19-2004s1.
those are 2A motors. you are running them with not enough current. set the current to 1500ma
-
@Veti done. would that cause my issues or could there be more? its ran fin on 1000mA current since i got it, but now that i think of it, the prints were never perfect.
-
it could.
-
@Veti also would you know where i can find a chart or something for setting thermistors? i need to adjust both of my printers. this is the bed heater NTC 100K thermistor ( Beta 25/50 3950K-1%
