Dead duet?
-
one of the v+ port has gone bad on the psu
the other works finne now
duet is up and runing again
thanks again!hopfully this is the end for all my problems for now
-
how bad is this ?
Supply voltage: min 20.8, current 23.7, max 24.5, under voltage events: 0, over voltage events: 0do i need to get a new psu ?
-
You might want to measure the voltage with the bed heater fully on and with it off.
-
DC42 I think this may be what has happened to meas well. I got a reading of 1.4-1.7 ohms from the VSSA to GRD, too low? I have 2000c on the hot end connections, but the bed reads normal room temp.
-
Check your M305 P1 parameters. If they are correct at least approximately, then a reading of 2000c on a thermistor channel normally means you have a shorted thermistor, or a short between the thermistor and ground.
-
The line is set up for the E3D thermistor, double checked it to be sure it still the way it has been. all the VSSA read the same with a meter, However when I plug the hot end on to the bed slot it reads normally. I found the Wiki page on the fuse: https://duet3d.com/wiki/Connector_and_spare_part_numbers#VSSA_fuse
I know I could solder the fuse like in the picture. the side with the resistor would be a problem for me going to the endstop ground. My hand wiggles on a good day, and shakes on the not so good ones. those terminals are pretty close together. I think I end up making a mess of things. I looking for someone who could do the work for me with the proper tools. Could that ground go to a different spot ( or is that just the closest. place)
I found one of the part numbers for the fuse, there are a lot of resistors on there that are all 10k is this one acceptable or is there another one they carry that would be better in your opinion?
-
Yes that 10K resistor is fine. Or you can leave it out, but then the firmware won't tell you if you get another VSSA short.
