closed loop nema 17/23 driver/controller for Duet 3 6hc board

Re: More Information for M569.1 Stepper driver closed loop control
I am interested in purchasing a duet controller for these https://www.ananasstepper.com/store/products/ananasstepper
have there been any developments or are there any plans that could take advantage of the tech? -
I have emailed them asking whether the CAN port supports CAN-FD.
-
@dc42 Hello, I am following up on this, any good news or ideas?
-
@supertb1, they have replied telling me that it does not supported CAN-FD. Unfortunately this means that the CAN interface is not suitable as the sole interface in 3D printing applications.
We have a closed loop expansion board under development, but it won't be ready for several more weeks.

@dc42 When will the closed loop Board be available? Can I already order some

@dc42 That's great news. Any idea on price point?
I'm currently favouring the ustepper, I have a couple of other cheeper brands that I've tried but a CAN interface that's directly compatible with the Duet ecosystem would be very welcome, especially if it's integrated with the external driver only Duet 3 board I think I saw mentioned a while ago.
-
@dc42 we're all excited
-
@dc42 I can't wait!!.. I would love to be on the preorder list should one become available
-
@dc42 +1 for pre-order
-
@dc42 Hello again, I am following up on this topic, have there been any developments?
very much looking forward to purchasing this new controller that has been in development over the last few months. -
@supertb1 we are currently designing the second prototype of that board using a more powerful processor, because the original processor had an undocumented quirk that proved problematic.
-
@dc42 That's great news.
I was just wondering what the score was with these myself as I noticed a reference to them in the documentation when I was setting up my Duet 3 mini this afternoon. At least I know it's still on the horizon.
It'd be great to keep my build totally within the Duet3D ecosystem, especially as I'm starting to get interested 3rd parties so may eventually be making more printers than I expected. Definitely want closed loop on one axis l, if not 2.
Please add me to the backorder when you are ready. Is there any forecast on unit cost?
I also remember a mention of a driverless control card, is there any follow up on that too?
Many thanks for all your efforts!

@dc42 Hello, following up on progress of the closed loop nema 17/23 controller for Duet 3... any good news?... can I start sending Duet3D my money yet?

We are awaiting manufacture of the new version with upgraded processor, and we have an intern scheduled to work on completing the firmware under my supervision starting later this month.

@dc42 Hello DC42, the suspense is breathtaking on the completion of the closed loop duet stepper controller... any good news?

Yes. The new hardware prototypes are being manufactured and should be available soon. Meanwhile the closed loop firmware is being developed on the old prototypes.
-
@dc42 I would be willing to pay $200 US for the controller, has there been a price point discussed on this yet?... I would love to be a (beta tester/youtube unboxer) tester of this controller. Also what are you using for steppers, or have you come up with a duet closed loop nema 17/23 motor for this new board?
-
@supertb1 we are testing with Nema 17 and Nema 34 steppers with built-in encoders from StepperOnline. Price will be higher than a tool board but I expect it to be lower than a 3HC. We will also offer an optional magnetic encoder + magnet to go on the back of a standard stepper motor.
-
@dc42 set it to preorder somethere %-) willing to put some buks there

This is amazing! I was already looking into ways to add encoders to my Bondtech LGX extruders. Thank you for your hard work!
