Hi can you please provide specific information how to wire up and configure the pulsar on the 6HC duet 3d board. I followed the pulsar documentation, but it lacks the details how to configure the fan and pellet sensor.

Here are my specific questions:
1. What the recommended voltage for the fan? Is it ok if I plug it to Out 7 on the 6hc board with 5 volt output?
2. Can the 3.3V IO (IO_0 to IO_8) outputs on the 6HC board control solid-state relays (SSRs) for 230V heaters, or would we need to step up the control voltage to a higher level to ensure reliable operation?
3. Where to plug the pellet sensor and how to configure it?

Hi Václav Musil!

Thanks for reaching us!

Here are the details:
1. If you are talking about a fan, I guess you are using a Pulsar Atom. You can check on the wiring diagram the details for it:

2. Yes, the SSR are rated for 3.3VDC.
3. The pellet sensor can be wired to the Duet according to Duet standards, here is our wiring details:

If you have a pellet feeding system, you can check more details here: https://docs.dyzedesign.com/pellet-feeding-system.html#what-s-in-the-box

I hope it helps!
