Mach3 and G-Rex / MachIV motor reversal ?

« on: May 05, 2006, 04:28:59 AM »

Hi,

I need to have Z axis direction reversed, DRO´s and jogging are ok but machine movement is wrong direction.
In Mach3 you could just set dir pin active low to change direction but it does not change direction in MachIV? am I missing something, are pin settings not effective in MachIV?

Thank you,

Regards Mika

Post Processors / My notes for 5 axis post

« on: February 07, 2006, 12:58:02 PM »

In attachement I have compiled information I have collected for my 5 axis postprocessor.
My machine is gantry with 2 axis head.
Head have B axis (rotates around Y axis) and C axis (rotates around Z axis).
I did choose easiest way and did make adjustable head geometry so that B and C axis intersections eachothers, this way it is only needed to calculate X, Y and Z axis transformation according tool tip distance from pivot point and rotary axis angles.

Some problems are still not solved eg. tool tip following error changes according tool lenght.
