heater fault when print starts
-
@Veti i tryed this it did not work i have even replace the thermistor and autotune it and it still dose it (i had sock and fan on when i auto tuned and fan off when printing. it is as soon at the steppers start to move the temp starts to drop quickly

@Government_Bacon Looking at your config.g file, it seems that you only have a single tool defined and that is tool#1. So my best guess is that your slicer puts a TO command in because tool 0 usually the default. Try either putting a T1 command in your slicer start code or better still, define your one and only tool to be TO instead of T1.
-
@deckingman the tooling is set up right.

the temp starts to drop quickly
how quickly? can you show the graph?
-
@Veti i think i have fixed it i droped the motor mA down and i has been stable
i guess not it still drops -

Heater 2 model: gain 368.8, time constant 138.3, dead time 6.4, max PWM 1.00, calibration voltage 12.1, mode PID, inverted no, frequency default
Computed PID parameters for setpoint change: P10.5, I0.352, D46.9
Computed PID parameters for load change: P10.where are you saving those values? there is no M501 in your config.

@Veti I noticed that it wasn't there and I tried adding it but didn't work is there a line of code I should put in?

What didn't work?
After running the auto tune, send M500, then in config.g at the bottom of the file add M501.

-
@Phaedrux i did that and this what i got
-
That looks right for the first part. Now you need to edit config.g and add the M501 at the end.
-
@Phaedrux ok got the m500 to work and it still heater falted you can see at the end on the chart it drop really hard and then wasnt droping as hard
-
Just to verify can you post your config-override.g?
Is the part cooling fan running at all during that drop?
Did you run the tune with the part cooling fan on at normal print speeds?
What kind of hotend and thermistor are you using?
Have you physically checked the wiring? -
@Phaedrux the cooling fan was running full blast on the auto tune and i have a sock on and the fan was off when printing

i am using the bond tech cr-10 direct drive it has a e3d v6 and i have checked the wiring and my heat bed is independent from the main board

what do you mean by independent of the main board?
-
@Veti it is its own system you plug it in to the wall and set it manual
-
What is the heater fault error message shown in the console?
-
it was printing fine and then just drop temp
-

Is the thermistor cartridge and heater cartridge secured firmly? Have you removed them to check them?
-
@Phaedrux yes the thermistor is brand new and the heater is good and both are mounted good
i am useing this settup
