short-to-ground reported by driver(s) 2 4 9

[3dprintingnut]

hello, everyone

I have a customized 7 axis board based on duet 2 wifi & duex5, it keeps showing below errors as long as turn on power:
Error: short-to-ground reported by driver(s) 2 4 9
Error: over temperature shutdown reported by driver(s) 2 4 9

is there any way to fix it by revise the config.g? it's really boring to keep popping up the error.

are those physical chips getting hot?
does it report this straight after power up or after first movement?

If you are getting those errors without even enabling the drivers, it probably means that the SPI communication to those chips is not working.

yeah, I haven't enabled 2 4 9 drivers, coz I only need 7 axis, and used 2 drivers on duex5, so the rest 3 drivers were removed on board. is there any way to stop popping up the error?

@Veti those chips are not hot, they are not being used. it reports error as soon as power up.

you physically removed the chips from the board?

[3dprintingnut]

@Veti yeah, that's right.

@Veti yeah, that's right.

I expect you'll need to disable SPI poling of those chips in the firmware. I don't know how to do this.

You can use M569 with parameter R-1 to disable monitoring of a driver.

When I had this error message it was a broken cable (one of the 4 cables to the stepper).

Having it on multiple steppers might be caused by another reason.

[3dprintingnut]

@dc42 it's fixed, thank you very much.

[3dprintingnut]

@dc42 another issue, it shows below warning as soon as turn on power, do you know why and how to fix it?

[Veti]

that is normal for e3d hotends with silicone socks.

what hotend do you have?

[3dprintingnut]

@Veti yeah, I use E3D V6 hotend with silicone sleeve, is there any way to close the warning?

@3dprintingnut
FYI, I've seen this error when the drivers don't have any power... (on Duex due to a blown fuse)

It's simply telling you what you can expect from a runaway heater condition. It can be ignored but it cannot be suppressed.
