2 + 2 slave axis

hi i want to have dual steppers on y and z axis. in mach3 i can only see setting for slave for one pair of motors for one axis. anyone no how to get around this.
thanks

Maybe use closed loop steppers and simply common up the STEP and DIR inputs to the drivers????

You could change to LinuxCNC v 2.8 but that's a bit drastic!
I used commoned connections in the past as Voicecoil suggests without any difficulties. The only problem is you don't have any auto-squaring and will have to manually square up the axis if you accidentally turn one of the leadscrews.

If you want to go down that route I started a thread last year about installing LinuxCNC and updating to the version that allows auto-racking and setting it up. Clive C is a knowledgable user and added a lot of very useful help.

You've probably also seen the ongoing discussion about it in the thin clients thread.
