ToolBoard: 2 wires fan, heater fault and how to extrude ?

Veti

same thing happens on the first board?

Pseud3mys

@Veti yes, even with no heater connected

Veti

ok this is one for dc42 what the hardfault means.

Pseud3mys

but when there are no target temperature this not happen.
I checked, the board reset.
I would also like to add than I didn't load filament, I put the temperature by hand.

sorry, I didn't understand ? what is dc42 ?

Veti

just for testing execute

M307 H2 A597.2 C231.1 D12.5 S1.00 B0

and try heating again

Pseud3mys

@Veti
raise this:
02/12/2020 à 19:50:36 M307 H1 A597.2 C231.1 D12.5 S1.00 B0
Warning: M307: Heater 1 appears to be over-powered. If left on at full power, its temperature is predicted to reach 622C

Veti

the question would be. who is @dc42
https://forum.duet3d.com/user/dc42

but can you heat afterwards? i thought you are trying heater 2

Pseud3mys

@Veti ah okay.
I tried, heater keep running a little bit longer but the same issues appear.

@dc42 Hello, I have a fault with my heater (on Tool 1LC), with no error message. After a fews seconds when I start to heat, the heater pass in fault statement and in beta4 the tool board reset one second after the fault statement.
Can you help me ?

Phaedrux

What does your heater graph look like when you get the fault?
What shows up in the gcode console?

Pseud3mys

The graph start just ascend (like 10/20°c) and then the heater change to fault state and the graph start slowly getting down.
And I have nothing on the console, no error just the heater with "fault" under it.

Pseud3mys

@Phaedrux and with the beta4 the toolboard reboot when I get the error (so the temp is 2000°c for the graph)

R25 (kΩ): 500 ± 3%
β25/85 (K): 3800 ± 2%

I find this for the thermistor.
M308 S1 P"121.temp0" Y"thermistor" T500000 B3800
so I put this, the temp is 12°c when it must be ~19 I think. I have always the fault, do you now what I nead to change ?

At low temperatures, high resistance thermistors like that one have poor resolution and accuracy. So your settings may well be correct. You may be able to reduce the displayed error by adjusting the H parameter in the M308 command for that sensor.

Are you sure that you are running beta4 on the tool board? Use M115 B# (where # is the CAN address of the tool board to check). If you are, then after the tool board resets, please run M122 B# (where # is the CAN address again) and post the results here.

EDIT: no need, i see that you have posted the M122 report already. I will look into it.

Yes I read this on an other post in this forum, so I change this config with the default one in RRF configurator tool for my thermistor. Where there is a "C" param.

Pseud3mys

@dc42
This is my new config for the thermistor:

M308 S1 P"temp2" Y"thermistor" T500000 B4723 C1.196220e-7

Pseud3mys

the doc say:

Lnnn ADC low offset correction, default 0 (ignored if the hardware supports automatic ADC gain and offset calibration)
Hnnn ADC high offset correction, default 0 (ignored if the hardware supports automatic ADC gain and offset calibration)

but I don't understand, do you have an example of use ?

Pseud3mys

@dc42

(the Heater 2 is not connected, it is just the heater 1)

M308 S1 P"121.temp0" Y"thermistor" T500000 B3600 C1.196220e-7 H-7	; configure sensor 1 as thermistor on pin 121.temp0
M308 S2 P"122.temp0" Y"thermistor" T500000 B3600 C1.196220e-7 H-10 	; configure sensor 2 as thermistor on pin 122.temp0

I modify the config, now at 20°C it return 20°C but je same fault accure after ~30°C..
