Seth I can help you but I need some more info on your particular setup for your air intake and exhaust. What size and how much are they opened/closed.

Sorry I haven't replied back recently, but I did finally get things dialed in on my UDS. I will list the steps here just in case it may help someone else. This method may or may not work for other setups but for me using a rotodamper (Ralph’s model) and a 5cfm blower, this is how I set it up...

@David great point, I have done most all of my testing with an empty grate. I will definitely add some mass and play some more. I noticed last night that if I completely removed the damper and just used the fan, that I actually had very good control. Maybe the damper is just overkill, but its...

The one thing I feel certain about is that the range of motion of the servo should be tweaked to create an opening at 100% that is very close to your maximum air intake. After my first few failed attempts, I realized that my damper opening is MUCH larger than the volume of my 3/4" air intake. So...

@David I am doing a ton of experimenting so I will let you know what all I try. @John, so 28cfm @30% would mean about 8cfm at 100% (that sounds like a lot) my blower is only 5cfm and I have it all the way down to 50% max. Your PID setting look interesting. Can you clarify what HM ver you are...

hmm.....I might have stumbled across part of my issue. I just started thinking about the output size of the damper. When I tuned my rotodamper (for range of motion) I tuned it to open the crescent full at 100% and close the crescent fully at 0%. But since the damper opening is much bigger than...

Guys I run a UDS (55G steel drum) cooker. I just got my HM4.2 built and I am running Ralph's Rotodamper and a 5cfm blower (same size output opening as the standard HM blower just less cfm). I ran a couple of "meatless" test cooks and am not getting anywhere close to where I need to be in...

Hey guys could someone please shoot me a copy of your .rrd files from a recent cook. I dont have my HM built yet (still waiting on a couple of parts) but I do have my RPi up an running with the HM software installed. I have been playing with some customizations to the web interface and wanted to...

Yeah Ralph I never found a Prime dealer for the metal gear servos, but I found one with free shipping and thought it was a US dealer, until I bought it and got an estimated delivery date for late October. I just bought a couple from the link Steve posted and I should have them monday.

lol, thanks for the link, Amazon Prime has brainwashed me I guess. I was so concerned about finding it in Amazon, didn't even think to look for a US seller on ebay.

I have every other part I need for my rotodamper build but the servos are coming on a "slow boat from China". Would anyone be willing to sell me a one and ship it to me in Alabama?
