@dc42 Awesome news, thank you and congrats to Louis as well!

@dc42 Hey David,
What kind of current rating are you thinking for these boards?

@dc42 Hey David,

TristanUp to 6.3A peak (4.5A RMS) @ up to 50V.
We have the new hardware prototypes running now.

@dc42
I am adding cnc capabilities to a manual Lathe at work and was intending to use 2, 4'ish amp Closed loop Nema 23's from Stepperonline and a Duet 2 with expansion board for control. After reading this I would much rather use a MB6HC and the new expansion board. If I could get my hands on one of your new prototypes that would be great. Please let me know if you are interested in dedicating a board for cnc testing. I can be ready in as little as 3 weeks -
@3dpmicro depending on what else you want to drive, it is may be that a Duet 3 Mini + the closed loop boards would be sufficient for your system.

@dc42
Not much else. Spindle control at some point. I can see how the MB6HC would be a bit overkill for the application. -
@dc42 Hello dc42, it is that time of the month and I am as excited as I have been to take part in field testing the new closed loop controller and steppers. How close is Duet3D to coming to market? As always best regards.

@supertb1 we'll be starting the beta test phase shortly.

@dc42 I am interested to test, willing to pay for the hardware

@dc42 I'm with Martin7404

Sounds neat. What MCU do they use?
I'm definitely in for beta, if you're looking for volunteers. I have machines that are heavily EMF-limited at 325mm/s+, have stepper analyzers, and run 15k accel. I'll make sure they get the hot supper they deserve, and finally max out my Magnum+ with a .4mm nozzle.

I have a professional IDEX printer prepared for closed loop with Nanotech motors featuring integrated encoders. Since all the cabling is already in place, only the closed loop controllers are missing... I would be very happy to support the beta testing.

@dc42 I would also like to join the beta crew, and would purchase several once everything is refined.
Thanks -

Great news! I assume the intern? has had fun getting the code up and running
I'd be interested in taking part in the beta as well.
Looking forward to seeing how hard I can push the polar printer bed!

I have 7 x 1xd boards for my 5 axis 3d printer build will these new boards work with them?
These are for my 400 watt jmc servos. -
@hoops40 if you are already using servos with step/direction input then the 1HCL board is not what you need. It is designed to control a stepper motor in closed loop mode. the documentation is here:

For those people interested in beta testing the 1HCL boards please see this forum post here:

@t3p3tony thank you for your reply.
Will there be an update for position feedback for the 1xd boards? -
@hoops40 the 1XD board is designed for external motor controllers (which can be either open or closed loop). Position feedback would be handled by that controller not the 1XD.

@t3p3tony understood thank you.
