M303 H1 S200

i try

lui2004

i got this

23:13:25Auto tune phase 3, peak temperature was 221.4
23:13:19Auto tune phase 2, heater off
23:10:11Auto tune phase 1, heater on
23:10:05M303 H1 P0.5 S240
Auto tuning heater 1 using target temperature 240.0°C and PWM 0.50 - do not leave printer unattended

You have multiple mistakes in your config file:

; Axis Limits
M208 X-34 Y-1,5 Z0 S1 ; Set axis minima

M143 H1 S28 0 ; Set temperature limit for heater 1 to 280C

whats wrong here ?

@lui2004 Possibly the comma instead of a period. , versus .

Now i See my mistake.

And for E3d-v6 What i can do to solve my problem any idea?

Phaedrux

If it really is an authentic E3D hotend and thermistor I think your M305 settings are off.

You have M305 P1 B4725 C7.060000e-8
But should have M305 P1 T100000 B4388 C7.060000e-8 R4700 Or at least that's what the configurator gives for the semitek thermistor E3D uses.

ok i have change it

send this gcode for autotuning:
M303 H1 S240

result:

Warning: Heater 1 appears to be over-powered. If left on at full power, its temperature is predicted to reach 472C.
Auto tune heater 1 completed in 223 sec
Use M307 H1 to see the result, or M500 to save the result in config-override.g

Gcode M307 H1 Result is:

M307 H1
Heater 1 model: gain 447.7, time constant 133.2, dead time 13.0, max PWM 1.00, calibration voltage 12.3, mode PID, inverted no, frequency default
Computed PID parameters for setpoint change: P4.1, I0.098, D37.2
Computed PID parameters for load change: P4.1

Have you double check voltage of termopar/PSU printer?

Phaedrux

That looks like a normal warning. Is the temp stable now or does it still fault?

lui2004

till 5 minutes 235C stable

i will make a test print

lui2004

seems to be ok still print the calibration cube

other thin my print is not in the center of my bed

I assume you fixed this one too?

M143 H1 S28 0 ; Set temperature limit for heater 1 to 280C

lui2004

Yes i fix it
