Paneldue issue

antoine.voiry

All,
I have ran heater tuning as follow

M303 H1 P0.5 S240

And got

Auto tune of heater 1 with P=0.50 S=240.0 cancelled because temperature limit exceeded. Use lower P or higher S in m303 command.

If then I try

M303 H1 P0.4 S240

I get
Auto tune cancelled because starting temperature is not stable

StephenRC

Between each M303, you have to wait for the heater to cool off to room temperature.

Thanks
with M303 H1 P0.15 S240
I get

Warning: Heater 1 appears to be over-powered and a fire risk! If left on at full power, its temperature is predicted to reach 982C.
Auto tune heater 1 with PWM=0.15 completed in 561 sec, maximum temperature reached 165.9C
Use M307 H1 to see the result

And

Heater 1 model: gain 962.1, time constant 198.2, dead time 6.1, max PWM 1.00, in use: yes, mode: PID
Setpoint change: P6.0, I0.03, D25.7
Load change: P6.0, I0.36, D25.7

I enter
M307 H1 A962.1 C198.2 D6.1 B0 ; PID settings for extruder 0

Any clue on the frozen paneldue?

Update your PanelDue firmware to the 1.15beta version, if you have not already done so. It includes a workaround for a bug in the gnu C library that later DuetWiFiFirmware versions seem to trigger.

A reading of about 535 from the IR Z probe is normal when it is triggered.

If the thermistor you are using is the Semitec GT104-2 (the same one that E3D supplies with their hot ends), you should change the B parameter in the M305 P1 command to 4388.

Hello
I just did the upgrade while searching, thanks that works (thanks to your doc at https://miscsolutions.wordpress.com/paneldue/))

Summary
~~- the PanelDue is not responding,

the z probe is reporting 536 (not sure this is an issue)~~

I still need to investigate based on the information you provided.

I have heating issue,
I get a lot of communication issues

I am able to print, now, the heat bed is slow to get to PLA temperature but it works.
So this is looking like this can be closed.

I now have to calibrate the jerk, acceleration and retract (probably not in that order), but that's business as usual

What power supply are you using? If is is a 12V LED-type power supply, then there is a pot at the end of the terminal block to adjust the voltage. As long as you have spare power capacity, you can turn the voltage up to 13 or 14V to increase the heater power, A 10% increase in voltage increases heater power by about 20%. If you do this, you should retune your hot end heater because its power will have increased too.

Hello,
I am already running at 13.8V (13.5 under full load). I don't want to get higher than this.
I had the same issue with the bed before, it takes 60/80 sec to go to 60°, in all cases, that's so short when you print for 4h.

Is that right? E3D say to use 4267K:

http://wiki.e3d-online.com/wiki/E3D-Lite6_Assembly#Configure_Firmware_.28Easy.21.29

And the Semitec datasheet seems to agree:

http://www.atcsemitec.co.uk/gt-2-glass-thermistors.html

It looks like 4388K is for the GT204-2

I have already explained this in the wiki page on connecting thermistors. I already updated the E3Dv6 firmware configuration instructions, and I have just updated the instructions for the Lite6 too.

Ah, gotcha, sorry. I only noticed because I happened to swap my J-Head for an E3D v6 Lite last night. I had used the instructions for RepRapFirmware on E3D's website which says to use the book value for RepRapFirmware.
