Long carving job with multiple tool paths

Machines (Original/PRO)
1

I have a 2 sided 3D carve, with a roughing and finishing tool path. (as well as dowel holes)
each toolpath is several hrs long (especially the finishing pass)

I seem to remember a post where the OP was able to shut down the controller and restartat a later date.
I understood this was between tool paths.
Seems there is a way to record the absolute, or offset settings so you can restart the job later?

maybe someone can refer me to the correct post, or share this info.

Thank you

Mike

Hi Mike!
There are several post that come up when searching Keeping zero power down. @Aiph5u’s reply in Pause during carve might be what you were seeking.

All I do is before power down, send the machine to my work offset (0,0 of the workpiece) and take a photo of the 1F webpage noting the absolute XYZ positions.

Upon power up and after homing the machine, I issue the following:

G90G0X123.45Y67.89Z3.14

which translates to:
G90: Absolute mode
G0: Rapid movement
X123.45
Y67.89
Z3.14

For extremely detailed carvings, even this is not guaranteed to be dead on and I suggest doing an air carve first.

Here’s another option to avoid stall homing repeatability issues.

  1. Face your stock for correct thickness / Z-height.

  2. Profile the front left corner of your stock using the machine. Make sure you actually get the edges to achieve a machined surface and establish a clean reference.

  3. Shift your CAM origin to this location for subsequent toolpaths.

  4. Use the touch probe on this machined corner to re-establish your origin each time you fire up the 1F.

I did this recently and worked great.
