HM4.0 vs 4.1?

[Matt Birmingham]

I am looking to build a HM, and I was going to go the HM4.0 route because it looked like there are some issues with the probes with 4.1. So...which build is more solid/has a lower default rate right now, 4.0 or 4.1?

I have a 4.0 and have issues with the thermoworks probes.

If you have the time,,, Wait for 4.2 it should be available soon and will support a K Thermo Couple for the pit temp.

If you have no plans for servo use out of the gate, then you'd be fine with the 4.0. You can also use a servo with 4.0 with a minor amount of soldering, which a few of us have done.

4.1 has fan + servo support via the on-board cat5 jack.

If it were me, I'd probably go with the 4.1 board

"Soon" is relative . Another member has all the parts here for a 4.1 but this thread has me worried. I could get it all w/in a week and have it up and running, which is compelling.

Re: the K-type thermocouple, what's the benefit? I tried to find info in this forum but my search-foo isn't well tuned enough to find it. (Sorry in advance if there's an obvious thread somewhere.)

v4.0 is pretty solid and slightly cheaper than v4.1. If you're fine with the positioning of the connectors, and the lack of integrated servo support, v4.0 is your huckleberry.

The advantage of thermocouples is that they can take higher temperatures than regular thermistor probes. The have the potential to be more precise, but not in a HeaterMeter because we can't get that sort of resolution out of them practically.
