@pcr Sorry for the wait but here it is:
There's a STEP file in there too in case anyone wanted to play with a solid model file.

My uSD card died so I thought I'd try the RRF configurator to speed up setup.

Heater 1 has a PT100 on it and I set up what I thought was the correct setup. RRFC spit out this line:

M305 P1 X200 R2200

It should have been:

M305 P1 X200

RRF seemed to get confused with the 'R2200' parameter. Once I removed 'R2200', the sensor worked fine.

For the moment everything else seems fine.

I’m of two minds about it. Closed loop offers intriguing possibilities but it has to be done just right to be any improvement. The biggest issue is it will cost more money, be more complicated (and more parts to fail) and it isn’t guaranteed to be an improvement. Unless you’re a big name manufacturer, add $30 per motor on your machine. I’ve even seen a few different examples where closed loop feedback made the print finish look worse.

Also, TMC drivers have eaten away some of the features once thought exclusive to closed loop.

The Maestro docs say nothing about how to turn on the 12864. I haven't actually tried "just plugging it in" but I assumed there's something to configure as it seems like everything else on Duet needs to be configured before using.

Apart from one page on how to write your own menus, this seems to be the only meaningful thing in the Maestro docs about the 12864:

The Duet 2 Maestro also support the PanelDue colour touchscreen. Connectors for a 12864-type mono graphics display and rotary encoder are also provided (these are not yet fully supported in firmware).

I haven't actually started setting up the Maestro but I've set up a DuetWifi and DuetEthernet a year ago.

@deckingman I dug it up here: https://somei3deas.wordpress.com/2017/04/18/stepper-motor-and-electronics-cooling/

@jrdm I designed and printed one. Works surprisingly well.

I'd like to set up a Duet3 board to run a step motor in a constant RPM indefinitely (or until I request a different RPM), where I set an RPM not a distance.

If this is already available I'd appreciate a point in the right direction, I couldn't find it in the docs or the forum.
