Added Duex5 - Really need some help

One other thing, for the Duex wiring do you have the power leads wired as shown here? https://duet3d.dozuki.com/Wiki/Duex2_and_Duex5_Features#Section_Wiring
-
Update.
I tried to use driver 5 (on the duex) in place of driver 4 on the duet. That eliminate the overheating message on driver 5. However I didn't think I needed to change the U designation in the configuration since the docs say U is always the first extra axis. But with that I got the no movement which I did find out was from my homing sequences all calling for Z to raise 5mm to start.; homex.g

M584 X0 Y1 Z2:4 E3 ;two Z Motors connected to driver outputs A and E1To this:
M569 P5 S0 ; physical drive 5 goes backward
M584 X0 Y1 Z2:5 E3 ;two Z Motors connected to driver outputsbut that didn't work
Thanks again
GeorgeHere's a late thought. Is driver 5 that the error referring to the 5th driver on the duet or driver 5 on the duex??? Could it be reporting on the duex driver even though nothing is attached to it?

Maybe? I'm not exactly sure how the duex drivers are numbered, but I would think that driver5 would be the E1 driver.
Question is, do any of your drivers actually get hot? The warning temp would indicate that they are too hot to touch.
I'm still not clear on how and when you are using the U axis. You don't have a U axis endstop defined, so I don't think you're using it for leveling.
-
None of the motors or drivers get hot as this this error appears as soon as I turn the machine on. I'm convinced the error is from the duex. Here is the link on driver numbering. https://duet3d.dozuki.com/Wiki/Choosing_and_connecting_stepper_motors#Section_Stepper_Driver_Numbering
Which tells me I have a bad duex2. If I disconnect the duex the error goes away.
I am using the U as a second Z motor to get independent leveling using the BLTouch. When I home Z it will home in the middle, then go to the right edge and home, then go to the left edge and home, then either the left or right motor will be adjusted, then it will go to the center and home the last time.

You do not need a U axis to do that.
https://duet3d.dozuki.com/Wiki/Bed_levelling_using_multiple_independent_Z_motors
Can you post your homing files and bed.g so I can see what you're actually doing? I think you should remove the definitions for all the U axis as I think it may be causing problems.
-
I cant find the original thread that I followed when I originally set up the independent Z probing that showed using U. I have a print going right now but when it is finished I will comment them out and see what difference it makes.

The creation of the U axis is only needed when doing leveling using endstops. The Z axis is split into Z and U and each side is leveled by homing to the endstops. But you are using a probe, so no U endstop, and so no need for a U axis. None of your files even call to move it.
When using the probe to level as described in that link you only need provide the locations of the lead screws with M671 in config.g, assign your motors to the Z axis, and then in bed.g probe close to the lead screws.
Your separate issue of the driver overheating warning on the Duex is of greater concern. I would suggest that you connect a motor to each driver on the duex in turn and configure it and test movement to establish whether your duex drivers are all functional.

Isn't the BLTouch acting like an endstop? I just changed the config.g with all mention of the U parameters deleted. When I rebooted I still had the driver 5 error. Also I got no movement from any axis when trying to home. That is because the homing calls for the Z to be raised first. So, since I have the Z defined to include two drivers, the Z does not work without the U parameters included. I purposely skewed the table to the side a bit and when I restarted with the U parameters included, it homed and leveled the bed perfectly as it has been doing all along. From what I understand, the adjustment done to either the Z or U axis is done automatically after it is probed on both the right and left side. It is not a movement called out in the config.g file, but in fact I can visibly watch one or the other motors adjust after the probe.
I am first to admit that I am a novice at this, but I can confirm what has been working and what hasn't been.
I am now going to disconnect the duex and see if that eliminates the error.George
-
I disconnected the duex again. The error went away. I reconnected it. The error is back.
Do we need to get David aware of this in order to OK a replacement? Not sure of what the procedure is except I remember another thread where a customer said he needed David ok to get a part replaced.George

No, it's acting like a probe.

That's not how it works.
M584 X0 Y1 Z2:4 E3assigns the drivers to their axis. Now when you set values for the axis they apply to all drivers assigned to that axis. So any command for the Z axis applies to both driver 2 and 4.https://duet3d.dozuki.com/Wiki/Bed_levelling_using_multiple_independent_Z_motors
Please read that link and you'll see what I'm talking about. The only difference between what's described in that link and what you have configured is that you've also added commands for the U axis, which doesn't exist because it was never created with M584.

I'm not a novice, but I'm not omniscient either. Together we can work out what is happening and understand why.

For now that is a good idea.

Yes, that's what's happening in your bed.g. But there is no U axis.
-
@GeorgeM said in Added Duex5 - Really need some help:
I just changed the config.g with all mention of the U parameters deleted.
Can you share that version of your config?
-
Ok, I went and changed it line by line. I am able to get rid of all the U parameters except in M92. If I delete them in M92 it will not work.

What exactly does it do?
Where are your motors plugged in?
With the U stuff completely removed and the Duex disconnected what do you get when you send M98 P"config.g"?
-
When I try to home it stays busy and the arrow circles spins and then I get a homing error.
Same with either x or y. Same if I comment out the raising of z before I home.Motors are plugged into:
X in 0
Y in 1
Z in 2
E in 3 or E0
U in 4 or E1Well what do you know. With the duex removed and U removed from M92, it homed correctly.
With the duex reconnected and U removed from M92 - no movement and driver 5 error is back. -
I need to leave for about 90 minutes
