Extruder temp reads 273 at room temperature

by SvdSinner

My CR-10 recently started showing my extruder temperature as 273-274C at room temperature. I have checked the thermistor with a multimeter, and the resistance is appropriate. I even followed the circuit back to the mainboard and confirmed the resistance there. I even tried flashing the firmware to see if the firmware had somehow gotten corrupted but the new firmware still shows the same extruder temps.

Is this a fixable issue, or is my mainboard toast? (I've got a spare MKS Base 1.4 that I can try rebuilding it with, but obviously, I'd rather get the existing board back to working.)

Layer Shift, PLEASE HELP

by qwiktune

So i'm trying to print a mandalorian helmet (in 2 halves) on my CR10v2 (brand new) and i got to about 40% and it looks like my layers started shifting in a bit of a stair case effect. Does anyone know what might cause this? It's rafted to the bed so not moving at all, belt seems tight. I checked all the bolts and rollers seem good. I'm not sure what axis is shifting, but my assumption is the Y since its shifts backwards on the Y axis.....I printed a collapsible katana that goes up pretty high with no issues previously, granted its not nearly as wide.......I pulled it off the bed and took the picture of it sideways so you can see the shift better so that shift (on the left in the pic) is actually the top and the shift seems to shift further backwards on the Y as it goes higher.

CR-10 V2 BLtouch Firmware Update retracts the filament

by askdba

Hi, I've just installed BLtouch sensor and the firmware CR-10 V2TF1.1.6.0BLTouchV3.1PowerLossContinueFilamentCheckEnglishandChinese.hex to my CR-10 V2. As soon as I start printing it retracts all the filament and continues to try to print without it.

Did anyone face this strange behavior?

Thanks,
