High temperature in driver 2
-
good morning, yesterday I set out to mount the duet wifi that replaced me with one that had a critical error in one of its drivers, I put the duet on its box and I only connect the endstop, thermistor, fans and z-probe without connecting the motors , I am ready to turn it on and enter via web contol and only the high temperature message is repeated in driver 2, which may be causing this failure without the connected motors? I have in my possession several boards and if they work with the same components, it is a little strange the problem of high temperature without the engine connected, I hope you can help me, thank you very much.
pd: duet wifi, firmware 1.19.2, web control 1.19.3. -
Here are some likely possibilities:
1. That driver chip is faulty. Perhaps it really is getting hot, even without a motor connected.
2. The chip select signal isn't getting to that driver. In that case, a motor attached to it will not work.
3. The data out pin isn't connected. That will typically cause the driver to report everything (over temperature, stall, standstill, and short to ground).

Good night, I have connected the engines and the engine z is stuck, I turn off the duet and I disconnect the engine starts the engine again, if I change the shaft the engine works, I do not know what that is. ?
-
I think you are saying that the Z motor doesn't turn, but if you connect it to another driver output then you can make it move. Is that right?
If you have only one Z motor, do you have 2 jumpers in the second Z motor connector?
-
the second connector of z is bridged, if I connect the motor of the tower z in x the motor turns without problems.
-
I'm sorry, it sounds as though either the Z driver on your board is faulty or (more likely) it is not receiving its CS signal. Please ask for your Duet to be replaced.
-
Could you remap the firmware to disable driver 2 and pass it to driver 5?
-
I presume you mean driver 4. Yes, you can use M584 X0 Y1 Z4 E3 to remap the Z driver to driver 4 (labelled E1). In recent 1.20beta versions of the firmware, you can stop driver 2 producing messages by sending M569 P2 E-1.
-
good night, when I insert the command to stop the driver I get this message
M569 P2 E-1
Error: M569 no longer accepts XYZE parameters; use M584 instead -
I'm sorry, it should be R not E:
M569 P2 R-1
-
good morning, after putting the commands that you have indicated this is the message sent me G28
Warning: Error: Short-to-ground on drivers 2
Warning: Warning: high temperature on drivers 2 -
Are you using the latest 1.20 beta firmware? The R-1 option doesn't work on firmware 1.19 and earlier.
-
yes,using 1.20
-
Which particular 1.20beta is it? Run M115 to find out.
-
FIRMWARE_NAME: RepRapFirmware for Duet WiFi FIRMWARE_VERSION: 1.20beta8+1 ELECTRONICS: Duet WiFi 1.0 FIRMWARE_DATE: 2017-11-18
-
Strange, in that release M569 P2 R-1 should suppress messages from driver 2. I'll test it when I have a suitable faulty board.
Just to be clear: you are using these 2 commands in config.g:
M584 X0 Y1 Z4 E3
M569 P2 E-1Yes?
-
Good afternoon, I had all the commands on but the driver keeps warming up and as a precaution I'm going to replace it, thank you very much for all the help provided.
