Some Gcode generating programs

[Jonathan]

I've written a few little (and one not so little) programs to generate Gcode for some common tasks. I'll post them here gradually...

'Mad Professor' requested I make this one about half an hour ago - so here it is:

CNC HOLES GRID2.zip

It cuts a grid of holes within specified spacings and limits. Now outputs "hole grid.nc" in the same folder as you run the program from.

Please note I don't tend to bother with error checking! Put sensible numbers in and you should be fine.

[B]Let me know if there's any little program like this you want me to write.

Just tried running your hole program and it failed to start saying salflibc.dll could not be found.

Ahh, thanks for letting me know. Here it is:

salflibc.zip

Unzip and copy it to the same folder as the program or your windows/system32 folder if that doesn't work.

Hi Jonathan,

Thanks for that - that did the trick.

Cheers,

Looks like a very handy and quick program to use.

But could you also please add, Plunge Rate, and Spindle speed.

Best Regards.

For those Mach3 users not aware Mach3 does have a hell of a lot of wizards built in.

Jonathan not dissing your efforts maybe you would be better writing wizards that are not available built in, no need to waste time reinventing the wheel.

The feed rate it prompts for applies to plunging. I'll add the spindle stuff in a few minutes.

I didn't realise that there was a similar wizard in Mach3 until after I'd written this program!

Can you think of anything that's not already in Mach3 that you would like?

Not me personally I don't use the wizards but thanks for the offer.

If your at a loose end look on the Mach3 forum for any that are wanted, if you can do you will become very popular.

Well here's something that's not in the Mach3 wizards...indeed someone charges for a very similar program.

4 axis Gcode generator for XL timing pulleys. Mills the trapezoidal tooth profile using small endmill. A axis is used to rotate pulley allowing the 25 degree angles to be milled for the precise tool profile. Needs 1.3mm or less endmill for XL...I've got a 1mm.

PULLEY GCODE.zip

Consider this an alpha release. I see no reason for it not to work, the gcode looks fine in mach 3 (be sure to set the A rotations display and the A offset to the radius of your pulley) however I have not tried it on my milling machine yet! Again, no error checking yet!!

I've coded it so that all the dimensions are calculated from the few dimensions that define the trapezium (lots of trigonometry & scribbling)- so I can easily add other pulleys such as metric T series aswell as L, MXL etc...if anyone's interested.

(I know a form tool would be a quiker way of making these, but that's difficult to grind.)

Hi Jonathan,

Have you looked at Gearotic, a program being developed by Art (founder of Mach). He uses similar methods for cutting spur, helical and bevel gears and includes some pulleys too. Take a look http://gearotic.com/, it's a work of art - pun intentional :) There's also an excellent forum.
