Mach3 and G-Rex / Newbie help Please!!!!!!

« on: February 02, 2010, 04:40:25 AM »

Hi all,

I've built a 3 axis CNC table and it works fine but i was wondering if it was possible to have the home position in a different place.

At the moment when i press ref home the motors move to the bottom left hand corner, just like what is shown on Mach3.

What i would like to do is have the home position at the top left hand corner. The reason for this is if the table is at the home position at he moment it is very difficult to place anything on the table as the drill covers the working area.

What would be ideal is for the table to go home first on pressing the ref home and the for the y axis to move to postion y250 x0 then i would be able to get at the surface area.

I hope someone will be able to help me.

Regards

Rick

General Mach Discussion / Scaling Problem - Help Needed

« on: October 13, 2009, 08:37:10 AM »

Hi all

I need help with scaling :

I have set up my milling machine using Mach 3 software but i've come across a scaling problem between the X and Y coordinates on the screen and the X and Y coordinates on my milling table.

For example : a movement of 200mm on the table relates to 0.9mm on the DRO's

How do i set the correct scale on both X and Y axis so that 100mm on the DRO's equal 100mm on the table.

I've comfigured the software in mm's and i've set the milling table size in the Homing/Limits page.

Kind Regards

Rick
