Excellent work! I completed the X and Y ball screw installation on my PM728VT about a week ago. I still need to do the Z axis though. It is interesting seeing how you did it, since the kit comes with nothing more than an expanded parts list and I couldn't seem to find any additional info, or videos. On the Y-axis, I was lazy and found a way to install the ball screw without removing the saddle, or disconnecting the oiler hoses. When I got to removing the crank wheels, I had the same issue you had, but after hitting the wheel a few times I realized it was difficult to remove because there was a hex screw clamping it to the shaft key. I could use the fusion model if your willing to post it somewhere for download. Thanks for posting this video!
Thanks for taking time to comment, it is alwayts hard ot know if this stuff is valuable to people I had already stripped the machine down to completely seperate compnents including removing the Z-axis column (do not do this - there is no nod ajustment for tramming the milling head so you have to shim it) so i am gld you found a faster way ... After exploring some ways to ship the CAD files, I am beginning to think email may be the besty way to hanlde this
Could i get a copy of the mill model? i've got the same model and while i've already converted mine to cnc, it will make designing my own upgrades so much easier, holy shit Just a .step file would be awesome I'm even willing to pay for it! a part i recently designed for the 728 was a bolt on mount so i can have a small high speed spindle attached on the side.
The download site video will be up in a couple of hours - but it looks like the F360 CAD files may have been corrupted - I am going to try to recover them from back over the next few days - sorry 😢
