KmotionCNC with Cheap Mach 3 Boards?

[Tim G]

I was hoping to pick somebody's brain a bit about the possibility of using a really inexpensive stepper motor and Mach 3 control board kit with KmotionCNC. I would like to start dabbling with building a small CNC router for a friend of mine and wanted to keep things extremely cheap. The hope is that it will outperform the super cheap lead screw or belt driven setups on rollers we option see for under $1000. My idea is to make the cutting area around 20" x 30" max, and use a cheap 700w palm sized router as a spindle. I found this 4 axis Nema 23 stepper kit with a simple Mach 3 control board, and I was hoping I could use KmotionCNC to run it, repurposing the A axis as a slave for the Y to do a dual Y cheap ballscrew setup. I've sourced some inexpensive ballscrew and linear rail kits I'm planning to use. Here's an example kit I'm hoping might work:

Hi Tim,

You will need to purchase a KFLOP or Kogna for KmotionCNC to work.

Good to know, thanks! Did a quick AI search and it suggested KmotionCNC might work with Mach 3 boards, so thought I'd check. Would definitely prefer KFLOP, just trying to save a little on this cheap build.
