HIYA YA-NO, Looks good, please drop off a copy of this in the MACH TOOLBOX it is a section setup to SAVE things such as this to help others

Tony I ran your code and it looks good.  If you are interested you might want to consider building your application as a mach WIZARD. It could generate and LOAD your gcode program.

I have not been smart enought to figure out the Wizard creation so it is best left for others(;-)

Tony to run correctly you need to set the Axis diam correction to the same as the pipe diam. This way the A and X/Y axis feedrate willl be calculated better. AS is mach will only go as fast as the slowest component(normally A axis in deg)

Look on the settings page and input the tube diameter in the Axis DRO for corrections to apply.

I have a frontend macro that runs from inside the Gcode to program the parametric side  AND set the diam setting in the DRO

Hi Tony, I have a parametric Gocde program already done and it works very well. I am waiting on permission from the math author to use his calculations.

THe equation that works the best is #6 from the deriative math.  It best suites the plasma process and straight cuts based on the 90deg angle of Z and XorY

A axis is controlled in deg of rotation.   YorX axis is controlled in programed units (inches or MM)

F###  sets the feedrate

Are you doing it as a VB macro or just using VB to create the Gcode file??

Here is what your code looks like on a running machine. Notice the change of code required to "make" it run. The original code as you posted it is an error with the 3rd line. Also note that the G42 has NOT been cancelled.

You would NOT run it as a macro. It would be a Parametric Gcode program that has a programable front end.

YOu would set the parameters such as

P1Diam
P2diam
Angle
Offset
Thickness

Then as the gcode file ran it calculates each point on the fly and does the move to the next point.

Mach does parametric Gcode VERY well.  Mixed VB gcode??? NOT so well(;-)

I think the idea was to input 5 values and cut the tube (;-)

The math involved can be seen here:    Http://metalgeek.com/static/dan/derivation.html

It can be made simpler than I stated earlier as the formula calculates the Y as every 2 deg rotation of the profile so that will translate into a rotary A axis directly.Then it solves for a X displacement to create the profile.

Scott(popabear ) Is the one you need to talk to he can set you right up with a bar puller page and process setup.
