General Mach Discussion / Re: Help with Tool Offset

« on: August 06, 2009, 10:06:13 PM »

If you machine without the G41 or G42 in your code, the program will take into account the center of the tool, regardless what is the diameter of your tool.

With the G41 or 42 code, the program will take the tool diameter into account.

So what you can do, put code in your program to get close where you start to machine.

Place the G41(climb milling) or G42(conventional milling) into your code.

Put the minus Z value you want

Machine your part.

Lift the Z

Put the G40(remove the offset diameter or the tool)

And that's it.

But mach3 must know what tool number you're using, and it's diameter

Just look at second picture, this is an example where to place the G41 or G42 code.

And take a look at this website, click on G41 or G42(white letter) This will explain better than me

Hope this help, Jeff

You will need to add a G41 or G42 code to your GCode in order to cut outside your line.

The G41 or G42 code depend if your are climb milling or conventional milling or to the right or left of your line.

I'm not sure if my reply will help you but this sometime happen to me.

If I load the program I want to work with after all the homing routine and zeroing the part on the table, those weird things happen to me too.

So now, I load the program before doing all the homing routing, this solve some problems, for me at least.

Thanks for the reply, would something like it would be more suitable, I've seen some model like it on the web.

Just did a quick drawing with SolidWorks.

Thanks Hood for the pic, what is the purpose of all these coil ?l

Are they special coil that can't be found on the market ?

Hi Hood.

Could it be possible to see you coil winder in action, it would be very interesting.

Nice work, Jeff

General Mach Discussion / Your idea for a good Vacuum table (with Plexyglass)

« on: August 02, 2009, 06:28:57 PM »

Hi,

I have 2 sheets of 1/2 inch Plexiglas, 36 X 36 inches.

I would like to build a vacuum table for my CNC router.

How would you built it, would you use both sheets one over the other with spacers between and hook up vacuum hose between too.

Would you build 2 or only 1 ( 2, I could place both on the table if I have bigger board to machine)

Which is better, equally spaced holes, (if yes, what diameter should they be drill) or machined slot and put rubber material to be equal to the dimension of the board I want to machine.l

Would like to get your ideas because I would not like to scrap my material.

Hope to receive some good advice,

Thanks, Jeff

G-Code, CAD, and CAM discussions / Re: Importing a part into MasterCam

« on: July 30, 2009, 01:55:37 AM »

I don't know what version you have but normally, importing files from SolidWorks into MasterCam is quite easy

Select OPEN.

Bottom of window, select the drop down menu and choose :FILE OF TYPE

Select Solidworks files (*.SLDPRT; *.SLDASM)

Also choose OPTION and check  " Import SolidWorks History "

Normally, this will work but sometime, it will not, don't know why

Hope this help,

Jeff
