Sounds/looks like we are about in the same place in this journey. That could be helpful. I'm trying to keep the manual functionality of my mill since I don't want to program something quick and simple like milling a quick flat or slot on something so I am planning to mount my x motor on the left. I got my z axis motor in the mail today so I have been messing around with it and trying to figure out the cam software some more. I have to take my table apart to measure everything so I can model it (I've only gotten the y so far ),I mostly know what I want to do but still a pain. Especially since I still need it here and there. ( wish I had two mills). I want a complete mill model in my inventor program so I can toy with designs and improvements without waste. Kind of a pain. Been thinking about how to do the z axis too. I think I'm going to utilize the fine feed screw on the x2 mill. Has a ton of backlash but I think I can compensate on the software side. Might go into the arduino Code if I can't fix it in the firm ware or cam generator. I don't want to go to ball screws just yet. What kind of mill are you working with. Looks like it's a much bigger table than the x2. Might move on to my lathe if I get this working satisfactory.

My y is the same. I was surprised to see it had no bearings at all. I think the x has two thrust bearings but I might find a surprise there too? We will find out real soon. I think both. Acme screws kind of free float after they pass through the nut on mine but my x screw is slotted on one end for a drive. Might come in handy??

Yup no bearings on the shafts - - For the end user to install . .

Same kind of mess to figure out - don't want to just start hacking away at the existing structure - Gonna have to stare at it for a while and see what turns up . . . Fortunately the belt pulley is robust enough that it can be adapted to take some bearing . It's the stepper side - don't really want to load its shaft with the tension load of the belt, so will have to find room to mount a bearing shaft for that . . .

Well after tearing mine down....first time in about 8 years. X has two 52100 (10mmbore26x11mm)thrust bearings but y has none. I bought a 5200 axial bearing for the y but still not sure I want to use it. Bigger than I thought but I can always use it on something else if I don't use it for this. Almost done modeling.

Well got a little more done. Mounted the x axis. I put a 12-24-6.35 thrust bearing on the machine side of the y mount. Prob going to add another to the motor side tomorrow. Prob going to remake this mount but going to run with this version to see what problems I can uncover.

Did bring it to life just to prove to myself it would work. Noticed some binding on the y so I'm going to add another bearing on the motor side. But happy to see it move. Have a video but dot think I can post it.
