I have uploaded new video about the machine but basically I have wired all solenoids to 12V and the ground to SSRs which are controlled by 24V outputs from the UC300. a. Separate cabinets for controller, VFD, and pneumatics b. Yes exactly. Basically have relays wired to the RJ45 boards. Pin 1 is 12V and every other pin is a ground connection that goes to relays. c. In the new video you can see the setup of the VFD. I think I'll keep it with the AC line-in filter and also a large ferrite core that spindle wires wrap around. Small things as well like shielded wiring for serial wires going between VFD and PC. No plans on adding output line reactor.

So there's some research you'll have to do first when deciding on the radiator. In order to avoid galvanic corrosion from mixing metals in your loop you'll have to determine what metal the inner watercooling jacket is made out of. I know that lower-end spindles may have an aluminum jacket inside so an aluminum radiator should be appropriate for you. My spindle the manufacturer informed me that it's chrome plated steel inside, a copper/brass radiator was suitable. My 240mm I saw temperatures incrementally rise from 18C to 26C over less than 20 minutes of spindle operation. The manufacturer actually suggests an ideal delta difference between ambient and coolant of 10C so 240mm seems to be right on the money, but I wasn't comfortable that this rise happened quickly and with the longer jobs I have planned I upgraded it to a 360mm. The manufacturer of my radiators is XSPC, they're good if your on a budget. Their low-end EX radiators aren't very efficient since they cheap out on the fin thickness but these were essentially free for me.

It's like a kitchen/utility cart from Ikea, don't recommend it it's too flimsy.

Thanks and honestly I haven't, the B version I simply found a good deal on. According to the datasheet: "FN 2060 filters are also available as B versions without Y-capacitors for medical applications as well as A version with low capacitance for safety critical applications with necessity for low leakage currents" It seems to have to do with safety standards, Y capacitors seem to pose a risk in regard to leakage current across ground and the power lines so they aren't used in machines that make contact with patients, and the A version has small capacitance to limit that current to a safe level. Seems like both would do the job.

Honestly haven't tested that yet I always default to 20-24k for the speed. I think you'll be very happy with the UB1 and servos, good luck configuring everything!

Original stepper was fine just slow, I think AC servo let me increase Z axis feedrate by 800%. The stepper had better holding torque when unpowered; the Z axis sags when you cut power to the AC servo. For this 6040 frame a 1.5kw spindle is more than enough. If I could buy a spindle again I would go with more RPM. For single flute and small endmill work especially. Originally I purchased the 1.5kw 24KRPM model because the faster 30K and 40K spindles actually increased in diameter to 100mm at the ATC piston. I wanted to avoid modifying the Z axis assembly and further reducing the work area so I chose the 80mm OD spindle model; it was a direct replacement of the original spindle. My advice is to keep the spindle 80mm OD (1.5-2.2kw) and go high RPM.

Thank´s for your help.

That would make for a pretty big list, anything in specific you're interested in?

spindle is from jiangen, JGL-80 1.5R24-20, I recommend buying their larger units if you can accommodate the diameter. The toolholders with the golden nut are from Parfait a Taiwanese brand sold by the spindle company, they were expensive at $100 each. The rest are generically purchased from Aliexpress from various vendors, they all seem identical and runout of them is satisfactory so at this point I shop for the cheapest ones, they're much better at $20 each. Much bigger difference comes from the collets, Techniks are what I've settled on.

@@NikitaLab thanks so much, for your very fast answer

I estimate $7k will be the final cost. Good question about if I would do it all again. Honestly no good options existed out there for something I could accommodate in my house. While it has certainly been a great learning experience and that has value in it of itself I would have bought something premade if it existed. The closest pre-made machine would be the Datron Neo but I needed a cheaper machine to prototype and enter small scale production for my parts before locking myself into $2k monthly payments. I expect to use this machine to test the waters with a new line of products I've been working on and if all goes well I fully expect to have a much nicer machine very soon.

@@NikitaLab how did it go

Upgraded, it’s the JGL80 R24 - 20
