Your setup is amazing! Are you accepting spectators? I'm apparently not too far from you, unless we all wash away from Sandy!

Half-step it. Hell, 16th step it. you'll quiet it down a fair bit.

Can't believe it has been over a month since my last post, work is taking priority right now

I half step currently. There is a trade-off between microstepping and torque, especially at higher RPMs. Now that the control software is becoming stable I will try a few different microstepping options to see what produces adequate torque while making the motor quiet and smooth.

I purchased a Chugger SS pump to use for CIP and sanitizing. It is mounted under the bottom shelf of my stand:


When I ran out of kegged beer I completely tore apart my keezer down to every washer fitting. Cleaned it all and reassembled and then pressure tested. Made a keg of Rootbeer and tonight I am kegging a Honey Ale.

The brewing room was a bit disorganized so I bought some sliding drawers to sort out all the various parts:

Very satisfied with the results, no longer will I be digging through boxes to find the right item during brewing.

While trying to expand the functionality of the system I found a couple of HW errors on one of my PCBs. Turns out the board house I outsourced to had difficulty with my close signal lines. A couple of the lines were shorted together. Didn't take too much to fix the HW issues. I have also been working on the LabVIEW SW portion of the brewery. The brewery controller can now tell if a temperature sensor has been disconnected, temperature values will hold for 10 seconds before becoming disabled. The solenoid valve controls are also almost compete.

I have the week of Christmas off and my goal is to brew 3-4 batches to catch up. I also intend to keep working on the software.

Just wondering FB, do you have a way of automating your strike volume, if your hlt is not being filled by the pumps the tachs on the steppers won't be able to estimate this for you

Not FB but I have contemplated the use of digital scales under the all 3 vessels to calculate liquid volumes. Would this type of input work with Lab View (I believe that's the platform you're using)? If so I would think it would be very precise way to set strike volumes, track boil off rates and fine tune the sparge. Thoughts?

To use mass to calculate volumes, you're going to need the specific gravity of the liquid at any given moment in order to account for differences in density.

I will eventually have a way of metering the strike volume, actually two ways. The plumbing plan has strike water leaving the HLT and traveling through the HEX coil in the HERMS tank before hitting the top of the grains. The peristaltic pumps might prove accurate enough to measure strike volume.

I also have a backup in the works. Check out the ultrasonic liquid level sensor I picked up a couple years ago from eBay. Eventually I found three in total, one for the HLT, MLT, and BK. The HEX tank has a simple float switch for level control. My control board is built to accept the 4-20mA current loop sensors. All that is left is some cabling, mounting, and calibration.
