4th axis not turning

Post by danh84123 »

I have a Stepcraft D3.840 with the 4th axis attachment using the A axis on UCCNS.
The attachment works and turns with manual commands through UCCNC.

I am using Vcarve Pro V12.006 using g-code arc mm.

I have a 1.5" x15" piece of stock on the Y axis that I want to use the rounding toolpath gadget on. The program creates the toolpath and the preview looks good. When I start the project the program it follows what should be the correct path and X and Y axis but it does not turn the 4th axis.

The A axis has been checked both on and off for rotary

I don't know G code but I cannot see anything in the code to tell the A axis to turn.

You need to use a different post processor for rotary work.

This thread may help: UCCNC Post Processor

Here is another discussion that took place recently. It had me tearing out what little remaining hair I have.

Thanks to your replies and several different wrap post processors I finally got it to work.
I used Mach 2/3-WrapY2A ATC

Thank you
