Duet maximum achievable step rates

@dc42 I mean the interrupt rate. But don't waste time, I can do it myself by recompiling the firmware. Only if others have the need, it would be interesting.

Woah, hold on a minute. Are you seriously suggesting that increasing the maximum step pulse frequency is a), only beneficial to users of mixing hot ends, and b) a sub optimal thing to do for all other users?
Setting aside the other use cases for higher micro-stepping such as users with very small nozzle and/or layers heights or users with 0.9 degree motors or more recently 0.45 degree motors, possibly in conjunction with fine lead screws, how can having a lower maximum step pulse frequency be beneficial (or "more optimal") for other users?
All 0.45° motors (nema16-18) I got quotes for are "way north from" ca. 100euros, if they are marked "Don´t use for new design" they are slightly cheaper - maybe a little below 100 (oh and min quantitiy is 5 or even 10...), but maybe that is just me having not found the right place to ask or something like it (I only know of ec-mot... and lin-enginee... (sorry for obfuscating the companynames but I do not want to get banned from the forum) to have those)... So I guess as long as not some company rolls the market new, I personally will stick to quality 0.9°-steppers with higher gearing ratio (currently in my personal calculations cheaper). If anybody does know of a cheaper source for 0,45°-steppers please share!
That said I am also in favour for higher-step-rates
+1
but out of a total diffrent usecase: High-speed-printing (single-extruder-single-colour, e.g. e3d-(super-)volcano or maybe one day the newer slice-engineering-mosquito-magnum(+)) for lots of lots of series production parts...This post maybe a bit off, but I hope you do not mind - after all it is a public forum... ah and thanks for your hint above in your answer! I think you have a really cool use-case with your printer

Sounds like a net positive to me!

I run toolboards (not the 1LC, but inspired by) over CAN with klipper
thanks for bringing this up, looks very interesting!

Hi duet-team,
I am interested in a build of a bigger core-xy (450x450) with either the duet3-mini oder duet3-6hc. The build is optimisted for very-low-moving-mass for very high accel/jerk vals. Are you still updating the values for the alpha 3.3 for those 2 boards here when released in that chart?
Best regards

Good point, we need to measure them all again for 3.3.
