General Mach Discussion / Re: Mach3 Rotary Axis: how to return to zero position from -500k degree position...

« on: April 26, 2018, 01:44:24 AM »

Some Gcode you could try...

G1 A *********x  (where *********x is a multiple of 360 and a number close to the existing A axis DRO reading)
#99803=0
%

This should rotate the A axis to a multiple of the zero position with minimum rotation then reset the A axis DRO to zero.
You could then goto zero on the other axes in the usual way.

An echo from the past.

This demo was made in the early days, before the M62/M63 commands were included within Mach4. The laser was switched using the A axis direction pin and machine control was by the LPT parallel port using Darwin.

General Mach Discussion / Re: m10 m11 commands

A couple of points that may help...

All Mach3 Gcode must finish with a CR so it is usual to insert a null character such as % at the end of every file. If you do not do this then the last line of code will be ignored.
The Diagnostic LED's do not always work as expected so a Meter (or similar) connected to the mapped Output Pin may provide a better indication.
You need to be using Mach3 version .056 or later.

Those commands only take effect at the instant of axis (any axis) movement.

For example, the Gcode;

G0 X0

M11P2
G0 X1

Would turn ON Output #2 at the instant axis X starts to move to position X1 and;

M10P2
G0 X0

Would turn OFF Output #2 again at the instant axis X starts to move to position X0.

There are more details here;  http://www.cooperman.talktalk.net/files/27_files/Page652.htm

Hope this helps,

I am not sure my family would fully understand but this guy deserves every credit for his determination to build the CNC machine of his dreams. I certainly wish him every success and hope all goes well with the build and also that he manages to find some space to put it when it is finished.

Your Gcode runs just fine here so I am out of suggestions, sorry.
