@chrishamm Thanks for the reply.
I was thinking of faster streaming, maybe something along the lines of 100Hz. The added difficulty might be that i'm using CAN Connected boards.

It would be an alternative to making custom boards.

@NineMile thanks, I've included this in 3.6.0-beta.1.

@amimafe If you save a position, check G0/G1 for the R parameter to move back to that position, you can also use offsets to for example move to a Z pos above the previous pos, and then move down into that position.

@dc42 The Adafruit documentation is ambiguous because it's internally contradictory by one byte. So I don't know.

@gloomyandy i did look , great 🙂

@moth4017 What you are seeing is the current expected behaviour, there is a feature request to change this, but I do not think it has been implemented yet (or if there is any commitment to implement it).

@droftarts Awesome! Thanks much!

@oliof Deltas would likely want wildly different IS compensation for Z versus XY since Z is the one axis where everything's going the same direction, but assuming per-axis IS settings become a thing in RRF, there might be a case there!

@dc42 I don't use an accelerometer to tune IS, but the caliper method.
I've now switched from ZVD to EI3 and do some test prints.
IMHO belt teeth cogging would have a much higher resonance, more like VFR-artifacts?

@droftarts Do you need quicker cycletimes than 0.33 to 5ms?
And yes this is the entire purpose of this question.

@Dep There is a feature enhancement request for this already, along with various side issues, see:

T3P3 created this issue in Duet3D/RepRapFirmware open Feed hold #745 T3P3 created this issue in Duet3D/RepRapFirmware open Controlled deceleration when a homing switch is triggered #746

@DonStauffer I think there's enough drivers and I/O on a Duet 3 Mini 5+ with Duet 3 expansion Mini 2+ (to give 7 motor drivers) to drive your setup.

@bug2k22 Moved to firmware wishlist.

@gloomyandy For example, the Protocol 2.0 used by DYNAMIXEL XL330-M288-T, PWM servos cannot be used for torque control and speed control. Two-way communication can be used not only for servos maybe digital sensors or other non-real-time device control.

@LindsayC Ditto!!!!

Bambu Lab may also use a similar algorithm to achieve flow calibration.

I checked the code and it is consistent with your guess. Automatic calibration uses DFT to determine frequency and amplitude, and the golden section search algorithm iterates.
Without developers have no chance.
