General Mach Discussion / A axis trouble calculating help!.

« on: March 21, 2012, 09:15:59 PM »

Hi guys,

I have my chinese machine working fairly well untill  I installed the A axis motor

gearbox is 50:1  motor is 200 steps per turn ..1.8 DEG  microsep is 8 and I want the a axis to be angular.

I am trying to set a axis steps per  to the right value

I have set a axis angular .In tool path a-rotations enabled

I did (200 x eight) x 50 /360  

I tried running these numbers with no success . 222.222222 (the result) is nowhere near right in practice
I then tried the trial and error and found that 229 is almost right but has a small error.

x,y,z are all spot on ..well .01 mm.. ok for wood

I am surely doing something wrong or not clicking something I should .
Its driving me nuts knowing that my machine is not really "notational l control "

General Mach Discussion / mach3 and monstar 6040

« on: March 02, 2012, 09:55:55 PM »

Hi all ,

First post here

I am just starting with this huge hobby and my ignorance may be astounding ..If this is a stupid question just ignore me .

My machiune is a Monstar  6040 with" a" axis chuck and it will arrive in a few days (hopefully)

The mach 3 setup in the manual does not allow for the a axis .

I wonder if somebody has an xml file to share  that works with this machine ? Of is there one here that I am too lazy to find?

Of course Ii will have to fine tune it but it might be a safer starting point for me
