General Mach Discussion / Re: Y-axis confusion

« on: December 29, 2009, 05:21:17 PM »

I still don't get it. My X+ is table moving right to left (as you say) but Y+ is table moving front to back so tool is moving back to front - that is where the "problem" seems to be. The Mach3 display makes sense for X movements but is backwards for Y movements. At the end of the day, the object being cut is a mirror image on Y. That can't be right.

cheers,

General Mach Discussion / Y-axis confusion

« on: December 29, 2009, 03:55:13 PM »

Ok, I completed installing a CNCFusion kit on my MicroMark (X2) mill. That all went smoothly, electronics working, etc. Then I started configuring Mach3. Worked through the videos (which were great!) and the docs. I do not have home or limit switches on my mill at this time. But, I put machine zero with the X table all the way right, Y table all the way forward, and Z at top.

   soft Max    Soft Min
X 8.50"        0"
Y 3.90"        0"
Z  -8.40"      0'

This all makes sense to me. When I jog, everything moves in the correct directions and I understand the movement. Now for the problem:

I created a little G code to draw a rectangle with a pencil chucked in the mill.

G00 X2
G00 Y1
G00 X0
G00 Y0

I then set the wok coordinates to the middle of my table and set X=Y=Z=0 (pencil touching the paper). When I run the code the table moves towards the + direction (the same direction that the -> arrow key makes it move) for 2". Then, the Y moves. It moves in the direction the ^ up arrow key moves it. But, on the Tool Table display on the Program Run screen, the Y moves up on the display - which is the opposite of what the Y is actually doing. So, I end up with a figure that is flipped in the Y direction.

I've messed with reversing the Y, etc but can't figure this out.

thanks in advance,
Michael
