Temprature sensor error unknown temperature sensor channel

Are you printing over USB or are you uploading the gcode to the duet using the web interface?
Do the heaters work otherwise?
Have you PID tuned your heaters?
-
@Phaedrux uploading the file through web interface.
The heater can be set manually and work fine and i have PID tuned them. I upload a gcode file then click start print and i get this error message,
Warning: Tool 0 was not driven because its heater temperatures were not high enough or it has a heater faultthe printer will continue trying to print without heating the extruder so i just stop it. if i heat the hotend first then start a print it will print as i'm manually overriding the temp settings.
i think? -
Upload a sample sliced gcode file please.
-
@Phaedrux i'm not sure how to do that?
-
@Phaedrux its a huge file to cut and paste?
-
@Phaedrux i assume you only need the start file?

@Phaedrux this is the last code:

I think this is an issue with simplify 3d targeting the right heaters.
Try this, go to stay folder and create a new file called start.g inside it put T0 and save it.
-
@Phaedrux In my config file?
-
Well you should have a T0 at the end of your config file as well.
But I mean creating a new file in the sys folder called start.g with T0 in it as well.
Start.g gets run when you start a print.

@Phaedrux Thanks so much mate, ill try it out

M104 S285 T0
M109 S285 T0I would suggest editing your slicer start gcode to remove the T0 from the end of those commands. And put a T0 at the very start of your slicer start gcode.
-
@Phaedrux I have tried changing the T0 around and no difference really. I keep getting a M140 error which is the heated bed which i don't have connected. I would start a print and ill get these errors which i close and resume print as its been paused automatically due to a heater fault. if i start the print it will run for 600 seconds and stop. the strange thing is once that occurs as long as i dont switch off the printer or reboot the board i can send a file to print and it does without a problem. Maybe i need to disable the heated bed?

Ok, so you don't have your heated bed connected? Well that would certainly cause an error since it will try to heat it, see that the temperature isn't rising, and through a heater fault.
If you don't have it connected remove the commands to heat it.
-
so delete the M140 command?
-
The easiest way would be to just tell the slicer you don't have a heated bed so that it doesn't generate commands to heat it.
-
Thats gotta be it ! i never realized the slicer was sending a command to heat the bed. The printer i have been using must have the heated bed disabled in config as its a mains supply heated bed. I have a print running and in about an hour i will delete the heated bed command and see if that fixes the problem ! thanks so much for the help !
One thing that frustrates me is the homing of Z is really slow its showing as 2mm/sec how can i increase that speed? The initial raising of the bed is at 2mm/sec but after the probe has been activated the movement is much faster. It moves down then moves up to meet the nozzle faster than the initial z axis movement up. i looked in the config files M558 which shows
M558 P9 C"^zprobe.in" H5 F100 T2000 ; set Z probe type to bltouch and the dive height + speeds
Is the H5 the speed setting for the initial probing?
Thanks in advance
-
You can modify your homeall.g files to add a faster probe first and then a slower probe afterwards.
Where you have a G30 to probe the bed, change it to add a M558 F command to change the feed rate, then probe. First fast, then slow. Like this:
M558 F400 A1 G30 M558 F100 A5 G30The A1 says just do it once, the A5 says probe until two consecutive results are basically the same up to 5 times.
