V25, 4th axis basic. Odd things. see screenshot, post processor and code.
Here's the issues-
1. if I set the stock wizard for a cylindrical workpiece and then generate code to cut a shape inside it (as pictured in the screen shot) why will it just generate code off the parts geometry. Shouldn't it allow me to generate code starting at the boundary of the stock and machine into the stock until I reach the parts geometry?
What's the point of being forced to run the stock wizard, if the code fails to see the stock as stock to be removed?
to run this part, without being able to start at the stock is irritating. I can only start at a level I pick for the start, BUT that level is dependant upon the Z location of the geometry underneath it. SO...I am stuck with cutting huge amounts of stock on some parts in a single pass, and very little stock when cutting at Z locations with a higher Z value of the part geometry.
2. I am using a Mach3 PP written by bobcad (attached) it seems to send the tool to Y0 after a program completes. How can I eliminate this in the PP?
3. The simplest part of my part geometry (pictured) is the cylinder at the base of the skull. This should be the fastest part of the program. The cyl is concentric with my A axis, and should cut quite quickly seeing as it only has go to Z(location) and rotate in the A axis.
Instead it seems to break up the cylinder into many many different segments (not of consistant angular size mind you) and this takes forever to cut. Oddly, the coordinated Z and A cuts for the skull seem to go much faster than the cuts for the cylinder.
4. I seem to have the A axis's rotation stop after every line of code that uses it. I would think that their would be a way to have it more smoothly flow into the next line. Is this a PP issue or one in Mach3?
The machine is a BP with a peiseiler 4th axis all running steppers/SmoothStepperUSB/mach3.
Thoughts?
