Today I researched couplings for the ball screws and servos. Man there is a lot of stuff out there. In the process, I realized I somehow ordered keyed shafts on the 750 watt servos and a smooth shaft on the 1.3kW motor. I finally decided it would be better to have them all be slotted in case I end up going that route. In talking with DMM, they didn't have any of the slotted 1.3kW motors in stock and offered to just send me the 1.8kW motor instead as they had them in stock with a keyed shaft. So now, I have their largest servo coming for my Z axis. Sheesh.
The VFD showed up today from PM. It's a Hitachi WJ200-015SF. I have to say, there is NO comparison between this and the VFD that came with my router. None. Tons of inputs on it, configurations, etc. Super well built, at least from what I can see.
I also put the head back on the 940, thinking I might have some time to play with the VFD and the mill. Unfortunately, I didn't. I also took it off and put it back on again tonight. Just trying to get things aligned. I have to use it to make the mounts etc. It's not difficult, just put some blocks under it and set it on the table, slide it out with the Y crank. Nothing new to you guys I'm sure.
I did decide to run some power over to it temporarily.
I couldn't resist. That little motor for moving the head up and down does just fine. In fact, just to see what it would do, I leaned on the head pretty good. (the top of it) and the motor barely changed pitch. I put enough weight on there I wasn't really comfortable with the scenario...
Anyhow, it was surprisingly strong.
Seeing things light up and move was pretty awesome.
