Thread: 4th axis brake enquiry

I was in the workshop today trying to learn how to program simultaneously 4th axis and had a bit of wood on the 4th. When I put some pressure on the edge of the wood I can see a small amount of movement at the motor. I’ve got a digital driver on that 4th and wonder if it might also ‘have a go at’ self correcting, not as good as a closed loop thought i’m sure.
From the movement I could see it looks like the wee pulley on the motor needs some mechanical advantage help so I think your idea of the rotary table might be better. I see people using 30:1, 100:1 gearing, what kind of gearing is on a rotary table. At this point I wish I knew more about mechanical engineering. ..
All things considered was pretty surprised my attempts without using specific kinematic actually worked to program some simultaneously 4th axis action just using a basic mach3 post processor?!
