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.

Hi Terry,

Looks good to me - I will try it out later today and report back. 

Just one point - the wiz transfers the Port and Pin assignments correctly but not the Low Active state.

Hi Terry,

I think the wizard approach would be the easiest for the inexperienced to understand and use so may appeal to a greater cross section of Mach3 users (myself included).

Hi Terry,

I think it is a great idea and look forward to following your progress.

Hi RG,

No its' not a dumb question at all.

It is probably better that you get the information first hand by downloading the manual http://www.machsupport.com/docs/Mach3Mill_Install_Config.pdf
then checking the Limits section 5.6...

You will be an expert in no time at all
