homing a bridgeport cnc converted machine
« on: November 04, 2020, 05:35:18 PM »
Hey guys Newbie here, just bought a Bridgeport with CNC conversion running Mach 3.
 I'm trying to set up soft limits and G54 home point, I've watched the videos on YouTube and gone through the process multiple times but I cannot get my Table and my current job display to correspond with reality. The work is outside of the soft limits area...If I do get them set up visually how the table is I end up with no travel in the direction the Gcode program wants to run.
To be clear I am trying to set up my G54 home as the top left corner on my table meaning that the bit is as far right as it will go and as close to the y axis handles (machine front) as it will go.
It feels like the system is backwards because my cutter is stationary and the table is what moves.
I'm sure it's something easily fixable in a options menu or something but I cannot figure it out.

Which way is the table moving if you enter this into MDI and press enter

Standing in front of the machine long axis running left/right

Assuming you are using metric, if not replace X5. and F50. with X.200 F2.

G01 G91 X5. F50.

X axis should move to your left.

G01 G91 Y5. F50.

Y axis should come toward you.

G01 G91 Z5. F50.

Z axis should move up.
