Retrofit for what? That kit could either too much, or not enough, depending on what you are retrofitting.

Hi Mark, sorry I didnt has all the information there. Im retrofitting my tabla top mill (RF-30) I been reading alot and I think those size stepper motors are big enough to move the machine.

Thank you

I did my rf-30 conversion with the 540oz/in nema 23 motors and a 381oz/in on the quill. (48V)

I have never stalled in a cut and can do some pretty nice rapids, but I am using the stock screws so it might depend on your leadscrew pitch.

Hi, Im thinking of using some Nema 34 906 oz-in stepper motors for X,Y and Nema 34 465 oz-in on the quil. It nice to know that yours work ok with that size motors. cause i dont want to spend the money and only works half way right. Im also using the stock screw for now they are about 11 TPI so hope it works ok, but im not worrie too much about the rapids for now aslong as it cut ok. What material are you cutting?where did you get the stepper motors?

I've been running the mill on cnc for about a year now and cut tonnes of aluminium as well as some pretty reasonable cuts in iron and steel.

I've got some pictures of my conversion here:
buildlog.net • View topic - CNC Conversions
And it cuts some iron and steel in this thread:
Ryan's g0704...

The quill will start flopping around long before the steppers stall.
The conversion was originally supposed to be as quick and dirty as possible so I could do a g0704 conversion, but the rf-30 has proven to be very capable even with the stock screws.

I used this stepper/driver combo for the x and y axes:

Hi that looks nice. I hope to buy my motors some time this month and hope to get everything ready so I can use my machine as a cnc now. what kind of parts can u make with the MACH3 program? do you need a second program to make the drawing there first and then send it to the mach3 program. or you can make the program there on mach3 , or you can do both ways ?

Thank you for all your help

Jaime

You need three seperate programs.

CAD to make the drawings, CAM to convert the drawings to g-code and them mach3 to execute the g-code on your machine.

You can also write g-code by hand which is a good skill to have, but realistically cam is very useful for more complex parts.

Hi, I have AUTOCAD LT at work, and I make programs all the time, we have a CNC brigeport lathe, but it is an EZ path program . I still remember little about CAM and G codes from school long time ago. I need to look for all my notes and books. but i still remember things about it, so it shouldnt be hard. The motors and programs you have they are USA made or China.

Thank you for you help
