I wrote more control software. I'm happy with it so far, but still have not documented it. Driver software is rather stable as of late. Controller software is getting there.
Did some temperature testing and the results look good. Replaced all the coolant tubing with 3/8" ID, and have much better flow. Have a relay set up to control a chiller, but have not wired the chiller yet. I will publish results when chiller is in the loop. C
Building a box (2x4's and BE" plywood) to sit in my driveway, as it became painfully obvious that I would never complete the 'observatory' in any reasonable amount of time. This should allow for engineering data until the observatory is built. I'll probably have to sandbag it in place to keep the winds from pushing it around (it's on wheels). I should have the MarkIV in the driveway by the end of the month. This will allow straight up and north views, with south views dependent on how far I can put the box away from the house (control cables - computer will stay in the garage).
