Tevo Tornado Cura Duet Temperature reset and fan control issue

Phaedrux

Can you confirm that the part cooler is plugged into fan 0 and hot end fan connected to fan 1?

Also I wasn't able to get the config link to load from that website. Can you post the actual contents of your config.g to check over?

In your config your hotend fan (P1) is monitoring heaters 0 and 1. (H0:1) This should be H1 , so its monitoring hotend only.

Thank you for the responses.
I followed the suggestion from Phaedrux. The behavior did not change. After the hot end reaches temperature (after the print command is given).... it resents to 0 and cools down and fails.

You have 3 fans it looks like the third has a ; this will ignore that line.

The first fan what is that? you have a setting of s0.3 that will reduce it's max speed to 30% and will probably conflict with print G-code and possibly cause it to run all the time.
Have you attempted to PID tune?

What are your voltages during warm up?

What is your start g. in the slicer?

Your parts cooler fan should remain OFF until the G-code commands it on- if it's on all the time you have a configuration issue.
Which looking you have H0:1 I don't know if that is an actual setting as mine is H1
Also your parts cooler should be S0, not S0.3

This is my config

@culbert425 said in A curious resetting problem:

give it something to print --> starts normally... then
it gives the message:
warning: Tool 0 was not driven because its heater temperatures were not high enough or it has a heater fault
... and so the nozzle heater quits and the print fails as it cools down, ALSO, after it transitions to print - the default ON part cooler fan goes OFF (then comes back on after you quit the print, and stays on during all non-printing times).

Please post your slicer start GCode, also the first 50 or so non-comment lines of the file you are trying to print.

Your fan configuration in config.g looks OK to me.

Phaedrux

It looks like config-override.g is being loaded (M501 at the end of config.g) can you post the contents of that as well? I'm guessing it will just have PID tuning values for your heaters.

What slicer are you using? Do you have any layer change gcode configured? Seeing an actual sliced gcode file as David has requested will be helpful.

@culbert425 It would appear that you're not using the right place holders for Cura to interpret. Or rather, it looks like maybe you've got the wrong bracket type. I think Cura might use curly brackets {} instead of square brackets [].

SOLVED SOLVED SOLVED

First... what a KICK ASS community - ya'll came to help a n00b quickly - provided good advice and examples

Extruder Temperature reset to 0 when print started
Cause: these three lines in the printer profile from Cura

M104 S[extruder0_temperature] 
M109 S[extruder0_temperature] 
M109 R[extruder0_temperature]

**Fix - Comment them out. **
changing [ and ] to { and } didn't help

Part cooler fan not on at beginning of print
Cura had a deep setting under cooling for first layer fan % - it was set a zero - this put a fan off command (M107) right before the print started... caused problems. Change that setting to non-zero.
Changed title of this thread for next guy who Duets his Tornado and uses Cura. It's working like it should now and I don't have to fiddle with anything before I send prints. I have completed the Duet Tevo Tornado Cura transition. (I tried to put "solved" in the main thread title and it got flagged as spam).
Thank you folks in this thread for the help!
