Counterweight is a pneumatic system right? How do you figure that one out?

Yeah, i like pneumatics...so i guestimated how much my Z-sled weighs and then i took a pneumatic cylinder that could pull twice that at around 5bar. There is going to be a chain between the aircylinder at the back and the sled at the front. One end is attached directly to the Z-sled and the other end loops down around a sprocket on the cylinder and then back up. This gives me a 1:2 ratio and less movement in the aircylinder...

Also, from left, that's a line filter? and a resistor for each drive? So instead of having a filter for each drive you do one big for the whole setup?

Yeah, i had major EMI issues, so i added a 2-stage 30A line filter and some huge ferrit cores to the motor-cables. Mounted everything in the chassis and the noise problem (almost) disappeared. The manufacturer recommended one line filter for all drives...so just did that...

The resister is a break resister for each drive to make the stop faster...
