Scale Button and the X & Y max. DRO's duly added. 

Excellent thought Terry.

Many thanks.

A BIG "Thank You" to OzzieII for the original idea and BR549 for all the work he has done on this screen / wizard.

I had to move around some of the components to avoid conflict with my global screen items but this has now been added as a page to my standard Mach3 screen 1024.set

This method is so quick and easy to use, with existing tool-path files, it is just amazing and once again, thank you TP.

As Ray has said.

Just as a general method the Velocity and acceleration are increased, in stages, until the motor stalls (squeals) then the settings are reduced by at least 30% (sometimes by as much as 50%).

Hi Regularjo,

It is best to place any questions as a new topic in the General section as this is only the place for introductions.

Mach3 will accept .txt / .nc / .tap file extensions - so as long as your GCode is in the right format for Mach to understand there is no problem.
If your code does not run you will probably have an error message in the status panel (bottom of Mach window) and this gives the clue to the reason it will not run.
Perhaps take a look at the sample GCode programs (Mach3 / GCode folder) and verify that your GCode is in the same format etc.

Check that you have the correct Port & Pin allocation for Step and Direction for each axis (Config / Ports & Pins / Motor Outputs).

As Hood has said.

May be best to Zip your code (assuming it is lengthy) and add it as an attachment in addition to your .xml file.

As I see it  possible causes could include;

a) The drill bit moving in its collet.

b) The Z axis loosing steps (possibly due to the velocity / acceleration settings being set too high for that axis).

(Assuming there are no positional errors for the X and Y axis, which may be difficult to see, then false steps caused by electrical noise could be considered unlikely).

It might be a good idea to also post what Mach3 version any project was developed with and any version it was tested with. History has proven things pop up to cause issues with some versions.

I was using Mach Version R3.043.066 with a kernel speed of 25kHz for the tests.

Hi Terry,

I changed the rotary Vel. & Acc. within the button to get my feed-rates equal on X & A(Y) and it's perfect.

My congratulations. 

(I'm on holiday now until the new year so will have plenty of time to play and do some more testing with this excellent idea of yours).

Hi Terry,

It didn’t quite get the steps per unit right (should be a rectangle) but I could easily adjust that.

As you suspected - the main snag appears to be with the rapids (G0) as the Y axis Vel. & Acc. are applied to the rotary (A) axis and the A axis Vel. & Acc. are applied to the Y axis. No problem if the rotary will run as fast as the Y axis but unfortunately mine is a bit slower. Again that is easily adjusted but it would be nice if the Wiz. did it automatically.

Great work my friend.
