Mill Wizards
« on: July 24, 2014, 11:15:07 PM »
I have my CNC mill up and running thanks to several of you who gave me advice recently.  I now want to start using it, but am not familiar with the array of CAD/CAM programs yet.  The first project I want to do is to make a front panel for the CNC control box.  This will involve cutting holes of different sizes in various locations in a flat piece of metal.  Is there a mill wizard that will simplify this operation for me?  I know I can do each hole individually with MillWizard, but I'm thinking there might be a library created by members of user groups somewhere.

thanks, rex

Hi Rex, I do multi mill wizards by copy and pasting the previous wizard using the edit page on the Mach mail program page. Every time you construct a circular pocket copy and attach it to the next one you do. I have attached a program of what to copy, obviously you don't need the command and end lines every time you copy and paste.
Have a look at this. its for 3 holes using wizard then copy and paste into the next one you do. Hope this helps.

Awesome; thanks Jim.  That's the approach I'll take.

In general, are there any wizard libraries that users post to so we can leverage off each other's work?

Hi Rex, don't think there are any threads on wizard linking applications, someone will tell you through the forum members if there is. Obviously the next step is to use a CAD/CAM software program to construct your programs. Remember as you progress with your programing skills there are lots of tricks you can use. I have tried several free download of CAD/CAM software but find using them causes more problems and broken cutter for the occasional user. I'm a hobbyist CNC and a pensioner so thing don't stick in my memory banks as easy as youngsters.
However I have used wizard part files to construct quite complex programs that include pockets, text, hole centres, slots and other wizard options all linked in the same program. It's a challenge and sometimes I loose the lot and have to start again, that's why I have a folder in which I save each stage of my modifications, so I can go back a step as every time you call up a wizard it removes the last program and give it a new file name.  My machine is down the shed (workshop) so I use a second computer in the house to experiment with program construction. Good luck with your CNC programing and remember a "Dry Run" might take time but could save you a cutter, a component or machine damage. Jim

The Mill Wizards from New Fangled solutions do exactly what you want and are not too expensive at $75.

I've done quite a bit of G-code by hand and with various wizards and such. But I have to tell you I get a lot more done and enjoy it a lot more since I got CamBam. 40 sessions to prove you'll like it before you buy.  I almost felt guilty at the amount of stuff I machined before I bought it.

Yes, I have those.  They work fine if I'm going to mill one hole, and I know I can manually put in coordinates to move from one hole to the next.  I was just wondering if there's a wizard that supports milling x number of holes in defined locations.  I'm going to follow Jim's advice of using the circle code from NF Solutions and string instances of it together to make my arrangement.

Gary, I have a demo version of Cambam and other programs.  I'm kind of overwhelmed right now with trying to figure out which one to invest my time and money in.  It seems to me that Cambam has only rudimentary CAD features?  I'm not at the level yet to know what complexity I can get to with that set of features.  Maybe it's all I need; that would be nice.

Not sure I really follow, if you do a hole and post then another at a different location and post etc etc etc you will end up with a gcode file that contains all the operations.

I was talking about the next level up, perhaps a wizard in which I would merely tell it the x, y and r coordinates of each hole in the work space and it would generate the final code, and perhaps draw the pattern for me.  If patching elements is SOP, then that's what I'll do.  I have seen the wizards that place holes in circular and rectangular hole patterns, but my pattern will be more complex.  I'm in education mode, finding out what's available and what people typically do.
