Title: reversed image? in mach
Post by: Biggo1 on March 15, 2009, 03:51:43 AM
1. After MUCH messing around I have finally got my system to run.
however. one minor glitch - my axis all run in the right direction - ie: left button moves x axis left, right button moves it right, up moves y axis up, etc, but the trouble is that in mach i see the reverse for the x axis in the table/work view screen.
that is, when I move the x axis to the left, it shows on the screen as moving to the right, and vice-a -versa.
What is going on???
there is no need to move the motion allocation for the keys, either on the keyboard or on the virtual jog control as they are all working correctly - it is just the visual window in Mach that wants to see things the other way around.
2. Does anyone have a good schematic for limit switches as I don't appear to be having much luck with mine. They are always either 'on' in the diagnostics, or do not work if I reverse their active high status.
help

Hi,

You need the jog keys to control the cutting tool movement, not the table. On my mill, the left button moves the table to the right so that the tool bit moves to the left. Similar thing happes on the Y axis.


Cheers,


Peter.

As Peter has said when the table moves to the left the cutting tool effectively moves to the right of the work, which is what the Mach screen is showing. It takes a bit of getting used to but think of the jog keys as moving the cutter on the work instead of watching the table movements.
