so it would not reflect the z position in dwc?
it is hard to tell if the baby steps did take effect

That's correct, the Z position displayed in DWC is the commanded Z position, not the Z position after allowing for tool offset, workplace coordinate offset, bed compensation, axis skew compensation or baby stepping. However, DWC shows the current baystep offset on the Status (or Print Status) page.

upgraded from 1.21rc2 to 1.22, and it seems no matter how i tick baby steps it doesnt show on Z axis.

well 4hrs into printing, i think the e3d sensor (blue wire) did the trick. odd though cause when i measure the resistance its like 70k-100kohm and not the pt100 value of below 100ohms. its now cleaner than ever. i also replaced the cartridge and moved back to a newer 24V 50W ceramic type with 100% pwm.

if it happens again, i think the heatblock screw holding the sensor is not gripping correctly, but that is a long shot. (my theory that is.)

@dc42
new thermistor, on that pic..
i replaced it with the one included in e3d v6, seems stable so far. but i didnt connect it to the daughter board as its not giving any values.

okay its happening again. now im not sure if my duet is broken

Thanks @dc42 @deckingman @T3P3Tony
i fixed it, seems like the thermistor is getting pulled and something was shorting the 5v rail. still using the new cartridge and ntc sensor (the pt100 was giving 2000degrees, but rtc1 is working when i place a 100ohm resistor) will troubleshoot that in a new chapter.
oh and a new psu too, seems like the psu was heavily grounded.

@deckingman
rewiring is the same..oscillations..will try using e3d generic 24v 30W heater..then tune to max P1

thats the thing. it was working for the past few month, didnt touch anything print print print. now this giving me that erratic motion is weird. so i replaced the sensor same output, and did the stuff recommended here.
just finished rewiring really, so im testing.

@deckingman

i think my issue is more than that..while printing it gives out erratic values from 210 down to 160-140, stopping the print
