PT100 sensor on Duet2 sporadically hunting for target temp
-
that fluctuation of +/- .5 degree is normal
-
My macros don't seem to progress. They are stuck waiting for target temp to be reached. Do I need to specify a tolerance somewhere?
I am also still getting heater faults when printing. I will try to capture that data if I can ever get my bed leveling macro to run.
-
post the macro
-
It isn't any one macro. It is all of them.
As an example:
M291 P"Preheating the bed to 60 and nozzle to 210 for accurate probing" T0 M104 S210 ; Set nozzle to 210 and release M190 S60 ; Set bed to 60 and wait M109 S210 ; Set nozzle to 210 and wait
As just one example, the macro I am running now can never get past the M109 command as it doesn't seem to think that hotend has landed on 210C event though it is +/1 one degree.
-
@mitch
that should finish.whats the next command?
-
It doesn't get past it in any of my macros. It just sits and hunts for temp there.
I have print statements, tones, you name it. It never gets past setting temp in the macros.
example from the video:
; Preheat to probing temps ; M291 P"Preheating the bed to 60 and nozzle to 210 for accurate probing" T0 M104 S210 ; Set nozzle to 210 and release M190 S60 ; Set bed to 60 and wait M109 S210 ; Set nozzle to 210 and wait ; Tone to get user attention ; M400 ; Clear movement buffer so tones play reliably M300 S666 P500 G4 P501 M300 S1111 P300 G4 P301 ; Move nozzle to center of bed at Z10 and drop to Z1 ; M291 P"Nozzle will now move to center of bed and move close to the bed" T0 M98 P/macros/general/1_Center_Nozzle ;P move to bed center ; Reset z to 8 to allow jogging up to touch bed to nozzle ; G92 Z8 ; Dialog to allow user to job z to touch nozzle to bed gently and then move Z down 10 ; M291 P"Carefully Jog the Z Axis until the bed and nozzle are touching and click OK" R"Setting Z=0" Z1 S3 G92 Z0 ; set z = 0

@mitch said in PT100 sensor on Duet2 sporadically hunting for target temp:
I am also getting heater faults during prints because it is not staying on temp.
please post the exact message you are getting.
did you use a special M570 command?
-
I apologize. Let me be more clear.
I believe I have two heater related issues.
-
It seems to not progress in my macros because it is hunting to hit target temp even thought it is within 2.5C
-
I have sporadic heater faults during prints. I need to capture more data on this to troubleshoot it. I have just returned to prints to find the print paused and a heater fault.
Special M570 command?
-
-
-
@Veti Thanks,
Nope, no M570 defined in config.g or config_override.g files.
-
but it does get past the M109 when you print something?
-
Yes it does.
I commented out the Tone generation and I saw this particular macro get to about line 79 and then it just drops out. Again, I think I have a few issues going on here so the troubleshooting is a bit confusing. I am trying to rule some variables out.

This is just acting really strange. I can put the lines into the console one by one starting at line 79 and it all works fine. But when I run the macro it just seems to get to around Line 79 and then just exit. No errors or warnings.
-
you don't have your macro in line 80 in ""

After trying numerous times the macro just started running. Part way through I got the heater fault.

@jay_s_uk Thanks,
I updated the file. Seems to still run the same. But I will make sure to find all the macros that have this command and add the quotes.
Just seems like sporadic behavior.
-
This may be a combination of some macro issues due to recent firmware updates as well as an intermittent connection near the hotend probe.
Thanks for the help. I am going to try to nail down the probe issue first to start to rule out some variables and make this easier to figure out.
-
post a picture of the temperature graph
-
I am attempting to run a print right now. The blips in the graph are heater faults I have had to clear. The temp just seems to stay on and then drift, clear it, it works again. Not spikes to 2000 or anything like that.
-
those are spikes none the less.
this points to either noise in the pt100 cabling. try to isolate the cables from other cables especially motor cables.
