Brake motors 1XD

3Dream

Good morning everyone,
use of duet 3 + 1XD to drive closed loop stepper motors.
On the Z I mount 4 motors of this type, but with brakes.
Sometimes (not always) it happens to me that by doing the Home of Z the engine starts before the brake releases, sending the engine into alarm.
I would need a slight brake release delay before the motors start.
Can you tell me if it is possible? I did not find anything reading.
Thanks to everyone and have a nice day
David

@3dream the easiest way would be to use M17 Z followed by a short G4 delay command in your homing file, before the homing move.

@dc42
a thousand thanks
very kind as always

@dc42
Good morning DC42,
even after inserting home Z and home all, M17 (not specific Z) and G4 P800 in the file, sometimes (not always) only 2 or 3 Z motors start. I switch the machine off and on again and everything works correctly. Can you give me some other solution to this problem please? Thank you

dc42

@3dream do you have a G4 delay call near the start of config.g, earlier than any commands that refer to devices on expansion boards such as the M569.7 commands used to configure the brakes?

3Dream

@dc42
I put G4 S2 as the first line in config.g

3Dream

@dc42
Perhaps I have not explained myself well, I mean that in the config.g there is already the G4 command in the first line. Maybe I need to insert it just before M569.7? or even before M569?
Thanks

G4 S2 at the start of config.g should be enough, but perhaps try increasing that to G4 S4 to give it another couple seconds just in case it's a bit slower.

3Dream

@phaedrux
ok, I'll try thanks

@dc42

Good morning,
even after inserting a 4 second pause the problem persists.
It would seem that the problem is always at the first start in the morning where 1 or 2 Z motors don't want to go.
I switch the machine off and on again several times and the problem disappears. The problem occurs only if the machine remains off for a few hours. Do you have any other ideas please?

These are incorrect. Only multiple extruder motors require multiple values. If the axis is made up of multiple motors, there only needs to be a single value for the axis, not for each motor. So remove the duplicate Y and Z values. I don't know if this would cause an issue like what you are seeing, but it isn't helping.

You can also send M98 P"config.g" to get a syntax check of your config.g file.

It may also help to see the results of M122 and M122 B# where # is the can address of your expansion boards.
