@mfs12 I've tried following the instructions but it doesn't seem to do anything.
i've got this on the configure tab

And then I switch to the record tab, hit run, it homes the machine and then nothing.
What am I doing wrong?

mfs12

@jay_s_uk did you configure your accelerometer? does it show any error?

jay_s_uk

@mfs12 it was an accelerometer issue. It didn't show any errors.
I've managed to get it to run. I did get an error telling me the auto populated frequency of 7 was too low. Increasing this to 10 allowed the test to run.
I also noticed that the progress counter lagged behind by one. So when the 3 run was being recorded, it showed it as being on 2/4 rather than 3/4

@jay_s_uk

can you describe the problem you solved with you accelerometer?
on my machine 7 is the lowest frequency i can enter. what RRF version are you using?

The process counter shows the number of completed test runs. Not the current one.

@mfs12 also, the plugin is fine for capturing data on Z on a delta but its no good for capturing data on X and Y.
This is because it homes the printer and then results in the printer trying to move out of range.

I think automatically homing the printer to run the test is a bad idea

mfs12

@jay_s_uk interesting feedback. I have no experience with delta printers. I will check this.

jay_s_uk

@mfs12 I'm running the STM32 version. I can run with 8 but not 7.
also, I created 2 sets of initialise for X and Z. I ran Z and it completed successfully. X wouldn't complete due to the issues described above. I then went back to the Z to run it again at a lower frequency from 10 and it had changed the axis from X to Z
And, when I had them all set at 7 and it wouldn't run, I changed them all to 10. It ran the first test but then threw the too low error, indicating its not respecting the value in the box when its overridden.

then should it say completed rather than progress?

@jay_s_uk can it be that you need to lower the z height first?
On a delta in homed position (zmax) you can not make a big move in x/y, because one or two rods will reach the end of the tower.

jay_s_uk

@cosmowave you don't get a choice. the plugin automatically homes and then runs the test

cosmowave

@jay_s_uk Ah ok. Sorry for that.

jay_s_uk

@cosmowave no need. I obviously wasn't clear enough in my original post

mfs12

@jay_s_uk if i understand you correcntly because of the implicit homing testing on a delta doesn't make sense right now. So for delta or in general the initial homing should be optional.

jay_s_uk

@mfs12 yes. the previous plugin was much better in that it allowed you to set the position of the head yourself. optional homing would be great

which parameters would you like to set? Having also a start position shouldn't be such a big deal.

jay_s_uk

@mfs12 to ensure you get full movement in Y, its best that the effector is at 0 in X.
Don't forget on a delta, the bed is round so only has full movement across the centre.
You also need to be able to set Z to an appropriate height to ensure the towers don't come into contact with the endstops

jay_s_uk

@mfs12 also, the input shaping type doesn't appear to being passed through when I get the F is too low error

jay_s_uk

@mfs12 Consulting with @gloomyandy he said

The Duet3 boards use a step clock of 750KHz we use (as in STM32) 1MHz the Duet 2 and Maestro boards use 937.5KHz. This gives a min F value of 5.72, 7.63 and 7.15 respectively. So I suspect that the Duet 2 and Maestro won't work with an F value of 7 either

You therefore may want to consider upping the default frequency to 8

sorry that I have to ask that. I'm doing something wrong. I now get to the point where he tells me that "InvalidOperationException in InstallPlugin: Command cannot be executed because the plugin service has not started".

jay_s_uk

@heartleander81 sounds like you're on an SBC and don't have the plugin service installed
see instructions here https://github.com/Duet3D/DuetSoftwareFramework/wiki/Changelog-DSF-3.x#version-330

Heartleander81

@jay_s_uk yes I use sbc. I look at the link thanks
