Attempt to move motors when VIN is not in range DWC shows 0.5V
-
Unsure what DWC is in the context?
The VIN terminals er screwed down tight
I see green (3,3V) , red (5V) and blue ...
I have switched it now to USB to interact via USB instead
M122 reads as:

DWC in this context is the Duet Web Control. The web interface you connect to. The machine status box shows the current VIN.
The M122 results will be more informative if you gather it right after the problem has occured.

you have no 12V or 24V. so when you try to move the motors they wont move.
-
@phaedrux ah! Right will look after work when i get WiFi connection again.
-
@veti the data is useless... I pulled it while it was connected with USB. I will pull better data in about 8 hours.

@phaedrux
So! I am home from work now, and I plugged in the DUET to my Ender 3 power supply which supplies 24 V (I just checked with my Multimeter and it confirms that part.The DWC interface says I have 0.5V and the M122 prompt says the same.. For shits and giggles I looked at the fan pins and they also say 24V. I have had issues with my hot end fan not working when I plug it into the board so that is my next issue after getting the board to function again.

check the fuses if it is blown
-
@veti I just checked the fuses with my multimeter, they all read 24 V
-
you measure a fuse by measuring the resistance across it while its out of the socket.
-
@veti Huh? But then there is no current to the fuse?
Edit: doh... ignore this
-
@veti Sorry mate, my bad... I took them out and checked them one by one and they are all fine.
-
@magnusjen said in Attempt to move motors when VIN is not in range:
@veti Huh? But then there is no current to the fuse?
Correct. Measure resistance, not voltage or current. Should be zero for a good fuse.
In fact, measuring 24V across a fuse that is IN CIRCUIT is a strong hint that the fuse is "blown". Meaning open. Meaning no current able to pass through. If you think about a good fuse IN CIRCUIT, it should read very, very, very close to zero V 'across' the fuse, because a good fuse is not 'blocking' anything, i.e. not blown. So the 'voltage drop' across the fuse is (almost) nothing.

"Good" as in "Zero Ohms"? (When out of circuit)
-
@danal Was to slow, I took them out and looked at resistance across and they all hit zero
-

Perfect... then they are OK.
Hmmm.... DWC still shows just 5V?
-
@danal Yes still shows 5V, I even pulled out the fans just for ease of work with the board.

With USB UNPLUGGED, and 24V reading across the pins on the green connector that is circled, which lights are on?
-
@danal
Power in is in the correct spot Check
Power reading across reads as 24V check
USB not plugged in Check
Wifi Blue light check
3.3V green light check
5V red light check
VIN blue light check
Z,Y, X stop red lights check -
Interesting....
Just as a final check of inputs and fuses, take a VOLTAGE reading across the two red circles (heater E0 VIN and ground on the big green VIN itself), with USB unplugged and 24V in on.
Should read 24V. Probably will. Still, with that confirmation, we can move on.
-
@danal Reads 24V indeed mate
I really appreciates the help! It happend quite sudden, I had the motors working and homed and when I had been working on wiring the fans (with the board turned off) it started with that error.
