General Mach Discussion / Mach3 Rotary Axis: how to return to zero position from -500k degree position...
« on: April 25, 2018, 09:05:00 PM »
Hi guys, bit of an unusual one here...
I am using Deskproto as a g-code generator,
on an x-carve modified with an A-axis.
running G-code for a tutorial you can find here: https://www.deskproto.com/gallery/venus.php
On the clearing pass I am using a milling strategy called 'helix' where the g-code essentially runs from one end of the workpiece to the other in a long single pass.
sort of like Meg Ryan peeling the apple in Sleepless in Seattle, in one long cut of the knife...
On a test run I noted that the A axis accumulated a very significant value, on the order to -500k, after about 50% of the g-code lines.
It made me wonder how I will be able to set the axis to zero when the run is finished,
without having to 'rewind' all those turns, which is what would happen if I simply issue a command for 'g0 a0'
anybody have any advice on how to return to zero easily when the A axis value is significant?
Thanks in advance for any help...
