Suggestions on easiest kit to impliment.

Hello.

I have just finished putting together my 3 axis cnc. Well the basics. I have not purchased the motors or 3 axis cnc board.

My unit is made from mdf and is roughly 24 " x 18 ". So it's pretty small.

My question is for hobby cnc ez kit.

Does it have easy to use instructions to wire, and then enter in the needed parameters for the mach software?

The Hobby CNC kit has very good assembly instructions and all connections are well marked.

Mach3 motor configuration varies due to stepper motor size, type ,screw starts, threads per inch etc...

Mach3 home and limit switch configuration also varies due to type of switches and if you use a switch for limit and home or separate switches.

Each machine will have its own unique setting in Mach3.

There a wealth of information here as well as the Hobby CNC User Forum.

Between the two you will get plenty of help so there is no need to be worried.

So If I buy the 20 threads per inch, how would I be able to tell the screw pitch?

Sounds like I would need to know the brand of threaded rod, and then go the the manufacturers web site?

TPI = Turns Per Inch

a 20 TPI = 20 turns of the rod per inch of travel

Sorry for confusing you, screw pitch and TPI are redundant as long as you are using a single start screw.

The vast majority of 20 TPI screws are single start.
