low motor torque

Neufra

I have NTC100K thermistors.
If you mean wich motors have little torque, it´s all of them. If you mean wich one stopped working after moving M584, it´s the second Z-Motor (connected to E0)

that just says it has 100k restistance at 25C nothing more. you need a specific type defintion of the thermistor like semitec-104gt-2.

for testing can you disconnect the duex5?

Neufra

I don´t know wich specific type of thermistor my bed has, it just says: "Thermistor 100k". (My hotends have those "Semitec-104gt-2" thermistors you mentioned)
When I disconect the duex, do I have to change something in the firmware as well?

if its a chinese bed. its most likely a B3950.

the semitec is B4725 C7.060000e-8

no

Neufra

Soo, disconecting the duex doesn´t seem to change anything, the Motor connected to the E0 output still doesn´t move.

About the thermistors, I put in the correct values for the Hotends.
(I have this heater for my bed. I will contact their support and ask them about the thermistor type!)

Veti

ok connect up the duex5 again and remap the second z to one on the duex5

The motor works now, I can´t reverse it, but it works. (I just flipped the connector)

Veti

@Neufra
reversing the connector should only change the direction. maybe a bad crimp job?

Neufra

No. That´s not what I mean. The motor works, independently of the connector direction. But I can´t change the motor direction through confi.g, only by reversing the connector.

are you restarting after changing the config.g?
are you editing the config.g in your sys folder?

also try M98 P"/sys/config.g"

Neufra

well, DuetWebControl asks me the following, after any change in config.g:

Reset board?
Would you like to restart your board to apply the updated configuration?

I click "yes" there.
And on top of the config.g editor it says:

0:/sys/config.g

Your command gives me that:

M98 P"/sys/config.g"
HTTP is enabled on port 80
FTP is disabled
TELNET is disabled
Writing to file: 4 S1
Done saving file.
Error: Bad command: 560 P5 S1

SIam

please post your new config.g again

by the drives you have four times M569 after that you use M560 this is wrong and should be M569

Neufra

ohhh, I overlooked that. Thanks
Edit: now the reversing of the motor works!
