Printing temperature drops down
-
@Pertti
I also have problems with the thermistor, I think it gives too high values, 260C seems to be good for PLA, resistance at 26C is 108000 kOhm. That's why I want to have a higher temperature. -

For starters I suggest you update to firmware 2.05.1.
Upload this zip file as is (don't extract it) to the /sys folder via DWC.
https://github.com/Duet3D/RepRapFirmware/releases/download/2.05.1/Duet2Firmware-2.05.1.zip
-
OK, firmware now 2.05.1. Thank's for smooth installing.
I repeated printing, but sorry to say, nothing changed. -
@Phaedrux said in Printing temperature drops down:
Is it actually set to 200? Your chart looks like it may have had a temp excursion and then dropped. Do you see any errors in the gcode console?
Can you share your full config.g and a sample gcode file?
What firmware version and DWC version are you using?
Please post the results of M122 and M98 P"config.g"
Config.g and sample gcode please
-
Ok, tomorrow.

@Phaedrux said in Printing temperature drops down:

I can avoid the problem by writing lines M104 S250 to the Cura machine settings/extruder starting code.
That means that I have to configure a new printer for every material, but that is actually good, because then you have all things set up for every material. -
You've got some problems in your config.g

Error: G10: Attempt to set/report offsets and temperatures for non-existent tool: 2
The tool definitions are incorrect and may be part of the problem with cura. The second tool has a G10 targetting T2, but there is only T0 and T1.G10 P2 R140
That should beG10 P1 R140 S0
Plus you have a redundant tool command for T0 at the end.; Tools M563 P0 D0 H1 F0 ; define tool 0 G10 P0 X0 Y0 Z0 ; set tool 0 axis offsets G10 P1 R140 S0 ; set initial tool 0 active and standby temperatures to 0C M563 P1 D1 H2 F0 ; define tool 1 G10 P1 X0 Y0 Z0 ; set tool 1 axis offsets G10 P2 R140 ; set initial tool 1 active and standby temperatures to 0C M563 P0 D0 H1 ; tool 0 uses extruder 0, heater 1 (and fan 0)

Your fan settings are unusual. You've defined fan0 and fan1 twice, but differently. The second definition overrides the first.

Plus, the way you have the fans setup with fan0 and fan1 being thermostatically controlled, but your tool definition has fan0 as the part cooling fan. So you need to decide what your intention is and wire it correctly. Which fan is on which tool? Which fan is thermostatically controlled for a heatsink, and which is a part cooling fan.
Your slicer start gcode sets temps using

is that where you see the temp drop down? That would match your graph.

Thanks a lot, Phaedrux. You gave me a good lesson. I think I need a couple of days to handle this. Anyway, line "G10 P0 R140 S205 G10 P1 R140 S205" has been there before I changed machine settings in Cura. The temperature matches reality.
The fans are something I need to take a look at. My previous board did not function these things at all, so I connected fans to the power supply.

I think if you remove those G10 lines from your start gcode you will solve the temperature drop problem.
