Hi there. Does anyone have an equipment profile for the custom 20gal Brewhardware setup? Been trying to dial it in and my mash volumes are so messed up in Brewfather.

Might help to post the profile you're using and how your mash volumes are messed up. Maybe post a sample recipe with your setup too.
For starters: make sure your "Mash/Sparge Water Calculation Method" is set correctly (should be "No sparge" for full volume BIAB) and that "include grain volume in mash limits" box is checked.

Here is the profile currently used, I had way too much water in the mash (about 3 gal over) which needed to be boiled off, the mash was super thin:Might help to post the profile you're using and how your mash volumes are messed up. Maybe post a sample recipe with your setup too.

Was going to ask about this but looks like you caught it and changed "sparge" to "mash".
Heading out for a few - will look closer when I get back.
With full volume BIAB your mash will be very thin. Still, something does not add up...
At what point were you 3 gallons over? Did you measure and record pre-boil and pos-boil volumes?
Are you boiling with no lid or are you using a steam condenser?

My pre-boil volume was 3 gal over. I had to boil off all that extra.
According to recipe, your total mash water was 15.01 gallons and pre-boil volume should be 12.59 gallons. 3 gallons extra would be 15.59 gallons which is more than you started with. One of those two measurements can not be correct.
Just to clarify - did you sparge at all or add any other water?

It's partially the absorption ratio. BIAB is closer to .23 qts/lb. You had yours at .383 so .383 minus .230 is .153 x 30.5 LBs of grain calculates to 6.4 quarts too much water.
The profile suggests 10.5 in the fermenter.
Add .15 gallons for trub loss and that's 10.65.
Add the 4% cooling shrinkage in the kettle and that's about 11 gallons.
Add 1.5g boil off and that's 12.5 gallons preboil.
Add .230 qts/lb absorption rate at 30.5 pounds = 1.75 gallons so that's 14.25 gallons of starting water.
So if anything you should have only been high by .75 gallons if all the other profile settings are correct.
Other thoughts. I would expect about a gallon of trub loss whether you leave that behind in the kettle or if you transfer all of it to a conical fermenter and then dump a gallon of settled trub before pitching. In my case, I would either change the trub loss to 1 gallon if you leave it in the kettle or set the into fermenter volume to about 11.25.
Are you using an open boil or lidded steam slayer? If the latter, the boil off should be set to .75 GPH.
Totally unrelated to the question at hand, did you really pitch or plan to pitch only one pack of lager yeast in a 10 gallon batch? That beer needs something like a 5-6 liter starter.
