That’s pretty damn cool right there if you ask me!

The enclosure I built has worked great for setup and practice but I think I am ready to start designing my permanent CNC enclosure. I think I would prefer a flood coolant system over a mist system. Have any recommendations on that? I'd also like to add spindle control to the Mach3 and a quick tool changer.
My new enclosure is built with flood coolant in mind and I'm still hesitant to get it functional.
Plus, I have my mist system functioning pretty decent now so it's working for the small stuff I do at the moment.
Flood coolant is going to be a mess and so I'm holding off because my shop is attached to my house and I don't want the smell or mess to spread inside.
You avoid that issue being in a trailer but it' still going to make a mess and you will have will be aware of what you are breathing in while you are working.
A mist system is worse in that regard so you should already have some sort of air filter or do you wear a face mask with cannisters?
If I do go that route, I'm going to start off fairly small and have found a few decent kits on Amazon and eBay for under or around $300.
It may, considering my enclosure doesn't have a ceiling.
Well that changes things
Always landing on 0 moving the same direction does not indicate 0 backlash, set your steps/inch in mach3 using as close to the full travel of the machine as you can to minimize error. Setting steps/In over .05” and adjusting steps to compensate for backlash is for sure what’s throwing you off, .9mm of tool deflection would be a broken tool unless it’s a 6” long 1/4” end mill. Once you have steps/in close you can set backlash by moving against the lash one direction, and stepping until you just move your indicator the other direction, or by the method you already stated and using difference in commanded and actual position

Yes, pretty sure I understood what you were doing, you cannot move out and back to the same position and expect to measure backlash. The difference between your commanded .05" and what the dial indicator is reading is your backlash but you should properly set steps/in as I suggested first. PM me if you're still having trouble, but doing what I posted should get you much closer than you are. No matter what trying to set steps/in over .05" is a bad idea.I was adjusting for backlash by using a dial gauge and using g0 x0.05 and g0 x0 to move that 50 thousands. Every time I move it using both moves, it lands on 0. That is why I think I have the backlash adjusted correctly. I can change the steps per to basically any number and if I make a + and - move I end up back on 0. That is why I don't think the issue is the backlash.
The issue I am having is that the g0 x0.05 move doesn't end up at .050 on the gauge. If I adjust the steps per to make it land on .050 and 0 after every move, it actually makes the Y axis more out of round. Maybe I am doing something wrong and need to try something different, but again that is why I don't think my backlash is the issue.

Nothing crazy, but I did make myself a new shop stand for the superjet. My old one was like a foot off the floor and working on it was killing my back. Now it's at a nice level to work on while standing up straight.

I have a design for an adjustable height
ski stand similar to what we used to use for our sleds. I even have the worm gear that allows it to raise and lower with a cordless drill, I just don’t use a stand enough to warrant building it yet.
Basically keep the base and ski bunks and add a scissor mechanism in the middle.
