Using variables with M584 doesn't work

CarlosR

@dc42 Hi, we are testing this with 3.4.0beta2 version, but doesn't work.
We tried:

M584 E{var.driverZero+0.0,var.driverOne+0.0,var.driverTwo+0.0}; extruders drive mapping

Where var.driverZero, ..., are integer values (20,21,22)

And we also tried to store the float value itself in an aux variable manually to test if the command recognise the params:

var driverZeroF = 20.0
var driverOneF = 21.0
var driverTwoF = 22.0
E{var.driverZeroF,var.driverOneF,var.driverTwoF}; extruders drive mapping

None of them worked...

@carlosr

 M584 E{20.0, 21.0,22.0}

didn't work either

@carlosr have you verified using M115 that you really are running firmware 3.4beta2?

Marcossf

@dc42 @CarlosR I've checked the version for you. Hope it can be solved.

By the way, it's SBC mode.

@carlosr we have confirmed that this is a problem. It will be fixed in the next 3.4beta release.

Do you have an estimated date when version 3.4 will be released? We had to stop the project due to the problem of the use of variables with 3.4.0b2 and SBC.

I can provide you with a preview build if you like. Which Duet are you using?

Marcossf

@dc42 We are using Duets 6HC, 1LC and 1XD boards, as shown in the versions above, in SBC mode.

If you can anticipate the new beta release, @CarlosR can continue developing the configuration for this machine. So, we will also see other possible problems that we will undoubtedly find after that step.

Obviously it will be delivered to the client when it is at least a stable version, hopefully 3.4 soon.

Thanks!

@marcossf you can find an unofficial 3,4beta2+ build for the Duet 3 main board at https://www.dropbox.com/sh/cq7q3g8coymo9s3/AABtPYEzV1_unETpKEMPInSia?dl=0. The 3.3 firmware for the 1LC and 1XD boards will work with it.

Marcossf

@dc42 OK, huge thanks. We will test it asap.

It's necesary to back the 1XD and 1LC boards to version 3.3 or would be valid leave it in 3.4b2?

For the 6HC, upload the bin and map files to /sys from DWC it's enough?

dc42

@marcossf if the 3.4beta files are working for you on the 1LC and 1XD boards, you can continue using them. However, a small number of users have reported issues with inaccurate temperature readings on the 1LC using 3.4beta firmware, which I have been unable to reproduce. If you experience this, then I suggest you downgrade the tool board firmware to 3.3.

Marcossf

@dc42 OK, thanks.

Temperatures aren't our concern now. Were still far from heat up or print despite having all the hardware finished

We saw some temp variations/inaccuracy with 3.3 and 3.4b2 during previous tests.
