Any updates?

[LazaroFilm]

Any updates on this project? An estimated release date? Also will you be able to use Klipper on this? This seems to be the perfect platform for it.

[AcrimoniousMirth]

Seconded.

Third-ed. This is an amazing controller that I would love to implement in my new printer. When can we expect a saleable release?

[eliasbakken]

Sorry that this is taking so long. It's way over due with an update and I don't mean to string anyone along. Its not clear how much longer it will take, perhaps months since we still have to do CE and FCC before releasing the final board. To give a preview of what is going on, 10 boards have been made for software developers, but there was an issue with the input stage causing the board to become too hot at high currents. A new revision has been made, but it needs to be tested and then we need to do a small batch to do CE/FCC. If the tests go well we still need some time to finalize the flashing and testing jigs and then start the 30 days pre order.

Been looking around for a second platform to use alongside Duets and this is interesting. Does it support PT100 sensors either directly or through daughter boards? Is it likely that two boards could sync together to get more steppers? Max step rate to 6 drives? Heater fault detection/protection?

[eliasbakken]

PT100 is supported through an external PT100 amplifier board, which is the right way to do it. You can not sync multiple boards with the same accuracy as the steppers have between them. I don't know of any board that can do that though. There are 6 internal steppers with two external steppers as well as an addition. Max step rate to all synchronously. Heater fault detection is a software issue more than a hardware issue I would say. For details on that, please refer to the Redeem project.

Kind regards, -Elias

Thanks for taking the time to respond.

When you say external amplifier board do you mean one that inputs a digital signal or fakes a thermistor input?

So something like this:

https://www.adafruit.com/product/3328

...rather than:

https://e3d-online.com/pt100-amplifier-board

[Casey7747]

Hey DocTrucker, Both of those are PT100 compatible boards. Not sure what you mean by fake a thermistor so I'll say this.

Adafruit -2/3/4 wire PT100 -SPI Comms output. It looks like there is no specific header made available for additional equipment on Revolve but one of the two external stepper ports may be able to be re-purposed for what you want. @eliasbakken please confirm. -May need additional programming, but not too much, to communicate with Revolve. -This is a higher quality design unit compared to the other. -https://www.adafruit.com/product/3328

E3D Online -2 wire PT100 (3/4 wire probe will still work but the system is generally less accurate.) -Analog Output(0-5V), needs to be connected to an analog input pin. It looks like all 8 Analog inputs have been used on board revolve. -https://e3d-online.com/pt100-amplifier-board

Hope this helps

Felix

Edit: Changed info based on what I could determine from PCB design A5

[DieKatzchen]

How goes the CE/FCC testing? Any updates?

[eliasbakken]

@DieKatzchen the project is cancelled and replaced by Recore: http://www.thing-printer.com/recore/
