I have finally figured out the three axis and every time I try to flip the fourth it bomgs.  I have a sherline 3700 on the fourth axis on a minitech 2 machine.  I finally figured out how to configure the other three axises(sP), but when I sent a jog or flip to the fourth axis I have an external stop.  I have tried setting the limits to 360 plus and minus and it still bombs. Also, under the diagnostics I have tried moving the a axis and have an external stop everytime I pass 10 degrees.   I have searched the tutorials and videos and can figure this one out.  What can I try next.

Hi, Jimmy

What ver. of Mach3 are you using, Look under Help, About for the ver #.

Is there a green border around the Soft Limits button ? , If it is green, Turn it off by clicking on the button and try it again.

Do you have a list of your pin settings or could you Post your xml file your running Mach with, Use the REPLY button and Attach it.

The xml is probably Mach3Mill.xml make a copy of it and re-name it to Jimmymill.xml.

The xml is located in C:\Mach3 folder, If it's a standard install.

Thanks, Chip

Chip, thanks for taking the time to help me.  I have attached the screen shot and .xml file.  I am running R2.63.

Hi, Jimmy

It seemed to work hear for me.

There were a couple pin's that were set to MPG 1 set to 13, 15 in conflict with your limit sw's but the mpg was set to off.

Turned on the Auto-calculator feature and set A axis in Tool-path seting screen.

Give this xml a try, if it still messes up try turning off/checking your limit's wiring.

Thanks, Chip
