Isel 4433 - Can I use Mach3 with it?

[AndyUK]

If anyone could aid me in finding a way of getting a copy of KAY for cheaper/free

Hello?

Don't think Mycncuk will be able to help much with that request, but there are certainly a few free alternatives around. I think the general userbase on here is either Mach3/4 (which most people buy after trying it for a month figuring that the £200 odd is worthwhile) or LinuxCNC (which is free, but has different operating principles, which means that a machine is typically designed with one or the other in mind, so its hard to swap).
