Printer don't heat after longer in IDLE state 3.4b7+1

Alex.cr

@SIam Similar problem but mine is on a Duet 3 platform.

@dc42 I can confirm a similar issue. In my case I have a 6HC+3HC+1LC. The only board effected is the 1LC. I am getting the exact same behavior as described above, except that a reset will not solve the problem.
I can check with and M105 and everything will show correct, but my hotend on the 1LC will not heat. I get the same behavior from Beta7, 7+1, and 7+2. I do not see this issue running Beta6.

In my case the only way to fix the problem is to use an M303 command to get the heater running above idle. Then I perform a reset and can send the heating commands as usual and everything will work.

With the 1LC heater on and commanded to reach 150C (heater 1):

This is the same error we reported here: https://forum.duet3d.com/topic/26463/bed-heater-stops-working-after-being-idle-for-some-time

For me it is happening on both Duet 2 wifi and Duet 3 Mini 5+; I'm pretty sure it was not always both heaters (Bed & hotend).
I don't remember having the issue on b6.

MikeDC

Its also happening to me with firmware Beta7+2 using duet3 + 3HC

I just finished one print job, loaded up another, had a cup of coffee and then clicked start.

20 mins later it still wasnt started and the bed was cold yet the print status was in printing state

kr15_uk

Same here, after one print is done I can not heat up hotend nor bed (from drop down menu and/or sending M104/M140)

Duet 2 WiFi fw3.4b7

Quite convinced I didn't had this issue with fw3.4b6, to confirm this I've downgraded now and will print a thing or too. Will report back.

Also I'll upgrade my Duet 2 Ethernet tomorrow or so and see if that's the case with Ethernet variant too.

dc42

All those of you experiencing this issue, please can you answer the following:

Does this issue only occur after you have done a print and then left the machine idle for some time?
Does it affect the bed heater, the tool heater, or both?
How does your GCode print file end? In particular:

Does it turn off the bed heater using M140 ?
Does it turn off the tool heater(s) using M104 ? Or does it set the temperatures low using G10? Or neither?
Does it use M0 ?

What (if anything) do you have in your stop.g file?

MikeDC

@dc42

no, it has happened to me if i have left the printer on for a long time without printing and it has happened after a print if left powered on for a long time before starting a 2nd print
its only affected the bed heater for me
end g-code
M122 ; debug following print

Also,
I have a macro to turn on off my heatebed contactor, even turning the heatebed contactor off/on with m42 it still will not heat the bed.
i have to power off/on the machine.

@dc42 said in Printer don't heat after longer in IDLE state 3.4b7+1:

Does this issue only occur after you have done a print and then left the machine idle for some time?

Yes, but I have to say that I don't have tested it without a print this I can do today I will post the result this evening

Does it affect the bed heater, the tool heater, or both?

in my case, Both

How does your GCode print file end? In particular:

G90 ; Switch to relative mode
G1 E-5 f3600 ; retrac filamnet
G91 ; Switch to absolute mode
M104 S0 ; turn off extruder
M140 S0 ; turn off bed
G91 ; use relative coordinates
G1 Z5 F1200 H2; lift nozzle by 5mm
G90 ; use absolute coordinates
G28 X0 ; home X axis
G1 Y195 ; move Y axis to end position
M106 P0 S0 ; Bauteilkhler aus
M106 P2 S0 ; beleuchtung aus
M107 ; turn off fan

Does it turn off the bed heater using M140 ?

Yes

Does it turn off the tool heater(s) using M104 ? Or does it set the temperatures low using G10? Or neither?

Yes

Does it use M0 ?

No

What (if anything) do you have in your stop.g file?

stop.g is empty

ÖrjanE

@mikedc M140 S0 and M104 S0 will not turn the heaters off; only change the target temperature to zero. Could it be that this generates a heater fault when it fails to reach that temperature? The release notes mention that earlier versions did set the heaters to the "off"-state after a finished print while the current (beta) version does not if there is a stop.g file present.

kr15_uk

@dc42

Haven't tried to do next job earlier than 30mins after 1st finished, I'll see if I can spot next print finish to test straight away.
Both, although I haven't tried cold bed print, always both heaters are on.
Just M104 and M140 to zero, XY home and M84
This is fairly new build so it's as generic as it gets out of online configurator.

On the previous post of mine, after downgrade to 3.4.0b6 on Duet 2 WiFI it works fine and 3.4.0b7 Duet 2 Ethernet has the same issue.

@dc42 My printer was 9 hours in idle state without a print job and the heating works

Alex.cr

@dc42

Basically, if the temp of the hot end goes below 18C or so. If I remove power for 24+ hours and then fire the machine up it will occur.
Mine just effects my hot end on my 1LC. My bed heater on my 6HC works fine.
Yes to all 3 questions.

I finished a long print around 3 hours ago today and left the printer idle afterwards.
I have just tried another print,
My main contactor does switch on but the bed is not heating.
i cancelled the print and thought i would do a couple of tests.
I can heat the nozzle manually and disable the nozzle heater
I have full control of it from both paneldue and dwc

the bed heater no control on temperature
i can manually turn the contactor on and off both by the paneldue and dwc
i can appear to enable / disable the bed heater
but it just doesnt heat up.

Only a full power reset will allow it to work again

dc42

@mikedc This is fixed in 3.4.0beta7+4, see https://forum.duet3d.com/topic/26787/unofficial-rrf-3-4-0beta7-2-files.

MikeDC

@dc42
is this a different b7+2 to what i am on ?
I used b7+2 to fix the z on expansion card issue but i still have this issue with bed not heating up after idle

jay_s_uk

@mikedc yes. the latest builds on that thread are now 3.4b7+5

MikeDC

@dc42
ahh now b7+4 thankyou :)))

I will install after my print has finished

SIam

@dc42 It looks good ! Thanks for fixing this issue

bastien

for me, b7+4 don't resolve problem

Fred-Y

@bastien New version have been published since b7+4, I believe the last one is +7
I don't remember having this error lately.

You should be able to download b7+7 from here:
