Laptop for CNC Controll

[JAZZCNC]

Hi chaps,

I've read a fair number of people saying USB to parallel port adaptors are unreliable.

How about PCMCIA to parallel port? Is this better?

I'm wanting to change my old PC to a laptop for controlling the CNC mill.

Thanks

If your running Mach3 then just using a Laptop with parallel port is hard enough let alone using any port converter. I believe PCMCIA it's not actually possible but don't quote me on that.!

Only reliable way is to use an external motion contoller. To be honest I've had so much hassle with the Parallel port I hate the bloody things so now will only use external motion control cards has they work so much better and give much smoother running of the machine/motors plus are far far more reliable.
They also take much of the workload away from Mach3 and PC so much lower spec PC's can be used and still get top performance.
