Mapping PT1000 sensors on Toolboard to Heater Outputs on 6HC
-
I am very close to having my machine ready but I am running into one issue. The sensor appears to not exist to the system when mapping my two PT1000 sensors connected to my Toolboard and my two heaters on my 6HC. I get "M308 S1 H999
Error: M308: Sensor 1 does not exist" and "Error: Temperature reading fault on heater 1: unknown sensor" when trying to interact with them.

As far as I am aware, this is a current limitation imposed by RRF. Heaters and their sensors must be present on the same board to function correctly. (I am trying to find the documentation that explains this in detail.)

@alex-cr Damn! That may be a serious issue. I cut my PT1000 wires for Toolboard length. I wanted to run the heaters separately, mainly for safety, as it is 100 watts of heater.
-
@alex-cr Maybe running one PT1000 off the Toolboard and then running one back to the mainboard...hmmm idk. I wonder if there is a trick to override that.
-
The only real way around it would be to drive the heaters with an external mosfet off of the toolboard. This way the toolboard does all of the work but power could come from some place besides the toolboard itself.
Edit: Somthing like this. link text

@alex-cr Well damn...seems just running the PT1000s back to the board is the only option, really. The mosfets would defeat the purpose.
-
Not entirely. You can still drive all of your fans and temp sensors from the toolboard itself. The power wires that run to the toolboard could be branched to power the mosfet. This way you don't need to rerun any major wiring back to the mainboard. That being said it might be easier to extend the wires for the PT1000s and call it a day.

Do you mean these limitations?
