Getting phase errors for extruder motor

bwenig

Hello, I just wired up my duet to a new printer and have successfully homed x,y,z axes. I am now trying to test my extruder motor. I am running a macro with

T0
G1 E10 F60

When I run this macro, I get the following error from the console:

Warning: Driver 3 warning: phase A may be disconnected, phase B may be disconnected

It will repeat this error about 20 times in the span of a second and there is no movement by the extruder motor. I have checked and replaced all of the wiring and connections. Not sure what the issue might be?

Thanks, Ben

Try mapping the extruder to another driver and test again. If it works as expected, you may have a damaged driver chip. If it doesn't work on that driver either but that driver works with other motors, then it's likely a wiring issue.

It would also help to see your full config.g and the results of M122.

@Phaedrux So I tried another motor on the same driver and got the same error. I mapped the extruder to another driver and got the same error. Tried a new motor on the new driver and same error.

Here is my config.g file:

I also get this error when nothing is plugged into the drivers

@bwenig said in Getting phase errors for extruder motor:

I mapped the extruder to another driver and got the same error.

So it follows the motor and the driver?

Did the new motor you tried on the new driver use the same wiring?

So you have two drivers now that are not working?

So which drivers are the ones having a problem?

Have you tried one of the drivers that is currently working on one of the existing axis like X?

@bwenig said in Getting phase errors for extruder motor:

E15360.00

This is a very high steps per mm. What kind of extruder is this?

Can you post some photos of the driver chips?

bwenig

@Phaedrux
Yes, it follows the motor and driver.
Yes I used the same wiring, and tried switching the A and B as well/
So now I have two drivers not working: E0 and E1.
I am hesitant to try the motor on a working axis! But I will test it now.

I am using a Replistruder. I got the config.g file from a research paper.

Here are some pics of the board:

You should use new wiring.

bwenig

So plugging the extruder motor into the x axis results in the same error, but I heard some clicking out of the motor, it tried to move a little bit.

I plugged the x driver back into the x motor and luckily everything still works fine.

I don't know what that is, but 16000 steps per mm is insanely high. How fast are you trying to command the extruder to move?

bwenig

@Phaedrux My extruder has very fine movement, so I think 160000 steps might not be too bad? Here's a video of me moving it manually: alt text

Phaedrux

Well it may limit speed.

bwenig

@Phaedrux Should I try a much smaller E value? Not sure what else I could try to get these drivers to cooperate

Phaedrux

Do the drivers work if you move the X/Y axis to them and remap?

bwenig

@Phaedrux No, they throw the same phase errors

Phaedrux

And if you put the X/Y motors on the drivers you were using for the extruder and remap do they work there?
