Yep - rip off Britain. i read earlier this month that the Chinese were complaining about our import duty and that it was harming our economy.

##### G-Code, CAD, and CAM discussions / Angle calculations for G-Code?
« on: January 25, 2014, 12:12:24 PM »
I have been searching for a while on how to calculate and angle in g-code.

e.g.

Stock - 50 diameter

I want to cut a a 45 degree angle

The mach3 wizards with cut a taper but the g-code overshoots the end. So if I put a x as 10 and z as 0 the the code will go to -9.5 (example), this is OK if it's an end angle but not if it's like the picture.

Questions:
I've seen a couple of wizards that ask for angle and then start z and end z. Isn't the z end redundant? e.g if i wanted a angle from x=0 z=0 @45 degrees to a stock diameter of 30mm then put in a z end of 500mm the angle using the z end would not be 45 degrees. I would have thought it would be either an angle or point to point and you get what angle comes out.

Anyway I would like the formulas for working this out myself - arc formulas would be nice as well.

thanks

Mine is set exactly the same - however it will only output G03 code. It will not output G02.

very perplexing.

Tried that - couldn't even get a price or help with program output.

Thanks - tried all combinations, it will not change from G03.

Checked and the option was already ticked. So un-ticked it and the wizard code does not change (still using G03). However the path generation now looks like this:

I guess the worst bit is that the Denford data website that has a dedicated section for the QT software doesn't even respond to questions.

Thanks for the link - I went direct to warp9 and they pointed towards syil - I guess they don't care much about the UK market.

Thanks again Jeff

Exactly - didn't know it existed and that is the trial version! A trial version where you cannot actually trial anything! Brilliant eh?

It's just the initial interface I like - perfect for turning, but then you can't see anything else work.

Shame really - it makes you wonder how they sell anything at all with trial versions like that.
