Ocho Camino on the discords.
My #1 feature request is an option to sort the gcode filenames by date. 99% of the time I want to print the file I just uploaded.
Scrolling thru all the files, while trying to remember what I just uploaded is pretty annoying. I end up with a lot of gcode files that look like aaaaaaSomeobject.gcode with the aaaaaaa to get it to sort at least to the first page. Obviously this isn’t a very good workaround.
I have a machine with 1Z cantilever bed. I'm using a Stepper Online 10:1 precision planetary gearmotor for Z.
I'm measuring a backlash of 0.044mm. (which is about 80% of the datasheet max backlash). 22% of a standard 0.2mm layer height
With a M425 Z0.044 S1
There's too much lag in compensating the backlash to make bed mesh really useful.
Ideally i'd like it taken up as fast as the stepper motor driver can take the steps on the reversal. Can we have an option for that? Like -S0 says do the backlash comp as soon as is possible?
I got significantly better layer stacking with my Delta with LDO steppers when i upgraded from OMC (same as ones linked above).

Filastruder carries them.

TBH it is easier to make slicer name file with YYMMDDHHmm prefix
Unfortunately PanelDue sorts A-Z so the most recent files are at the bottom, requiring scrolling.
Would be really nice if PanelDue allowed you to set the sort order.
The current RRF documentation for M593 indicates that there's a single frequency selectable for the input shapers. Will this be changed to support independent frequencies and shapers per axis? Machines are far from iso-resonant, so choosing one frequency and shaper for both axis will yield a sub optimal result.
Bedflingers in particular have radically different resonant frequencies.
On my crossed gantry 500x330 printer, one axis is best served by a 46hz ZV and the other by 68hz MZV shaper (according to klipper recommendations).
@dc42 if ram is a constraint, then that's an acceptable reason for duet2. But, i'd prefer if some other features were limited (like the LPC port does) to free up ram to support it.
If there isn't 2 axis input shaping in rrf3, I will await the klipper port to duet3. Duet3 mini port has been completed.
Input shaping is THE killer feature. And 2 axis is essential for it to work well.
@dc42
So i did another round of tests with a better setup.
Backlash is approx 20-24 microns with empty bed weight 1.2kg. With 2.2kg on the bed the backlash is approx 14 microns. Backlash is pretty much the same (within 10%) when reversing either direction.
200 step motor, 10:1 reduction, 20T pulley at 16i means 800 steps/mm
.024 * 800 = 19.2 microsteps = 1.2 full steps. Could that be applied instantaneously without issue? M425 with S0 could enable this if feasible from a code standpoint.

Adding a 2.2kg load to the bed (which weighs approx 1.2kg) changed the backlash from about 22 microns to about 14 (there's a variance of a few microns).

I should try the same shaper and freq for both axis to see how that impacts print results. Away from printer until monday...
Some before and after pix (ignore the schmoo near the bottom. i have a fan connection that is wonky). 2K to 14K accel at top. 200mm/s

We have reduced the stepper driver support from 5+3 to 5+2. T
Deal killer for me. Oh well. I was excited for this board. It was going to be the recommended board for CroXY.
I'm using a hemera on my d300 (with linear rails). it works fine and gets great prints.

I'm using tricklaser arms which don't pop off like magball arms do. I'd be very hesitant to use magballs and a direct drive extruder.
