I had about a month of anxiety waiting for that moment. It went mostly smooth. What I didnt think of ahead of time is that with the knee all the way down the screw goes down slightly below the lip of the casting but not far enough that it goes past the mounting pads. that created an oh **** moment when I had it in the air and couldnt get it to lie down flat on the cribbing. fortunately a slight adjustment of the cribbing fixed that.The pics of you getting that thing off the pallet brought back some memories of my experience with my 935TS. Thanks.

Finally done. Took a lot longer than I expected. Changing speed with the turn of a knob is mind blowing. And it is remarkably quiet--at least compared to my prior machine. A couple of questions--what is optimal belt position for everyday use? I have mine at second to fastest and i can get up to 1800 rpm (max Hz set at 90). Where do yall normally keep the ram for regular use? By my estimation flush to the front seems to give most Y travel. Thanks again to everyone on here for the help.

yep, 1800 is great.. that way you can go low or if you go over your 60hz (I go to 65) I can get a little more, after that I need to change pulleys (RARE)
Looks nice, DID YOU PRINT THAT BOX????

Nice job. This took me back to memories of my own 935 customization. I have not needed to change belt positions ever with my setup and I posted some speed test videos about it here:
As you can see in the video, I get a range of 54-3800 spindle RPM with the belt in a single position shown in the photo below.
yep. just grey PLA and some heat inserts. Will see how it holds up. I have a lot of other stuff in the garage that are PLA, they do just fine.

that must be a big printer.
Thanks David, I think I was wrong and I have mine on third fastest--Ill change it to how you have it and try. do you know what max Hz your VFD is set to? And thanks for all the info you put on here, and on flickr, it was a great help.
Just a regular Bambu, but used almost all the print bed

If I remember correctly, the max VFD frequency I have set to 100Hz. A bit higher than normally recommended, but I only run the spindle above 2000 RPM when machining softer materials like aluminum, and even then mostly on finish passes to size with minimal DOC. So far, in 7 years, the stock 3-phase motor hasn't complained a bit. On my 1340 lathe, I installed a Baldor vector-rated motor that I run up to 120 Hz (very infrequently).
