Interesting that the torsion arm created problems with your Z Axis. I made a setup with a cheap ball screw and 3.0 amp 269 oz motor and it works fine with the torsion attached. I know this is old video but I’m always mining for ideas.
Good to know you were able to make it work. I sometimes wonder if adjusting the preload on the torsion spring would have made a difference. In any case, its still going strong after 7+ years.
Thats what happens when you mount the lift on the side it pulls the head to one side the ball screw should be mounted in the middle of the slides and should be using nema 34 for z axis due to weight
Awesome, I have just been rebuilding my SX2 after one of my original motors died. I ended up purchasing a set of closed loop motors and drivers from en.jstuoge.com/index.php/Show/index/cid/200/id/294.html Dam they are fast and super accurate but having the same binding issue on my Z, thanks for the refresher in setting that up. It had been so long that I had forgotten just how to do the adjustment.
Could you help me? I have a couple of Servo motors like the one you have, I have some Gears which can be used on them. I would like to use them like your mill, but I dont have any ESC's r ( Motor Controller ) and I dont know much about CNC and where to start looking and learning about it. Do you have any idea's for someone like me who dont have much to buy a kit but in the same time I have the servo motors and a little bet of know how? Your help will be much apprishiated (sry my English ). Thank's
Mini mamo, I recommend the Synthetos grblShield for the stepper motor driver and then a PC running Universal Gcode Sender as the machine controller. However, you will need to be sure you have stepper motors and not servo motors. The motors I have are stepper motors. The grblShield does not work with servo motors. If you have other questions, feel free to email me at Tim@DIYmachining.com

You are correct, that's the risk with this lift mechanism design.

Andrew, glad the video helped!
