Glad it was something simple and it's up and running again.

Me too. Just another reminder of how much I have to learn....

I had a go of cutting some aluminum with it and seeing the chips fly made it all worth it.

Something else that is a little unusual with what you have done is the 20mm pitch Ballscrew for the Z axes is a much higher pitch than the norm most don't go over 10mm pitch but I guess with the gas spring there is not much work for the motor to do so will be able to move supper fast in the Z axes

Yeah speed is not going to be an issue with this machine. The Z axis seems to be able to move as fast as the others. I am impressed by how much torque and acceleration you get from those Nema 34 465 oz in motors. I have no doubt that they could handle a lot more.

I got mixed advice on choosing the ball screw pitch but I was under the Impression that using a slower pitch on one axis would limit the overall speed potential of the machine. I guess it doesn't matter now as all three of my 20mm pitch ball screws work well.

Now that I have done some test cuts, I can see that the limitations of the end mills and work holding make any other concerns about not having enough speed or torque irrelavent,
