Driver 121.0 Errors

TRATOON

I am using Driver 0 on one toolboard for my xtruder motor. I keep getting this error: Driver 121.0 warning: phase A short to ground, phase B short to Vin, phase A may be disconnected How do I fix this?

Phaedrux

The obvious thing to check would be the wiring to ensure the phases are properly matched. But all 3 errors together hints at perhaps some damage to the driver.

Double check your wiring.
What are the specs of the motor?
Please share your config.g and the results of M122 and M122 B121 after the errors have occurred.

TRATOON

@phaedrux The wiring is correct, I am using an E3D Hemera. The two wires for each phase are continuous.

My toolboard is mounted directly to the E3D Hemera

Phaedrux

Can you please try adding a G4 S5 command to the start of your config.g? This adds a short pause to allow expansion boards to startup before the config is executed.

Did this driver ever work? If it had, has anything changed or happened recently?

When and where did you get the toolboard?

dc42

@tratoon said in Driver 121.0 Errors:

The stepper wiring is correct.

I'm sorry, but given that incorrect wiring is a known cause of this type of error, we need supporting evidence such as photos. If we can confirm that the wiring is correct, we will replace the boar under warranty.

TRATOON

@dc42 I can send photos. I plugged stepper motor cable to another tool board I am using and it works so I will send photos of it connected to first board that has errors

TRATOON

@phaedrux driver never worked got it a few weeks ago from filastruder

TRATOON

@dc42 I have the pictures:

I just swapped the toolboard for another one I had on hand and it works. So it is probably that the toolboard had a defective driver.

@phaedrux Hello, I also have another Duet tool board! that has an issue. One of the pins for the VOUT selection for OUT 1 & OUT 2 came soldered improperly. Here is an image:

I am hoping to get a refund/replacement for this one

Hello,

It seems you have:

1x 1LC with no issues
1x 1LC with a short to ground issue
1x 1LC that is working, but one pin header is slightly slanted

Is that correct?

I can only find two boards ordered by you from Filastruder.

@elmoret One has a defective driver. I will look more into if it is improper soldering or bent pins on the other one. I would l like to return the one with driver issues while receiving replacement instead of sending both boards at the same time so that way I minimize downtime of my printer. It is 2 toolboards, you listed 3
