Identical artifacts/issues on two parts on the same print job
-
These were printed at the same time on my single extruder corexy build. The issues are consistent and appear on both objects. not sure why. is this a slicer issue? it seems too consistent to be something like a blob or extruder malfunction. The same object prints fine on my other printer. although they're pretty much different in every way.
Im having a rough few days with things going wrong if you've seen my recent post history lol.

@Turbo Bumping because i was able to upload the picture finally.
-
Would need to see some more information to get any real feedback.
Details on the printer (extruder, nozzle, etc etc)
slicer settings and config.g settings, etc.Just based on the photo, printing too fast?

@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

@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 -

those are 2A motors. you are running them with not enough current. set the current to 1500ma
