Title: Finding the middle of a circle.
Post by: Smackre on May 28, 2007, 06:05:12 PM


I have these 1" Dia. X 1" Long Plastic Peiced I mill a oval threw.  But the Oval has to be in the middle.  I think there is something in the offset page about finding the middle of a circle but I dont understand how it works.  So if someone can please show me how it works.  Pretty much all I want to do is use my electric edge finder to locate the middle of a round bar.

Thanks Eric,

There is a wizard for this, not used it myself but it looks straightforward enough.

I Dled the file.  But what do I do with the file?  I clicked on it and it said Wizard Installed.  But when I try and use it in mach3 it says file missing.  I might be doing something wrong.

It should be placed in your Mach 3 Root folder. Double click on the probe plug in while in the Mach Folder. It should place a Dll file in your plugins folder. You have a to go into ports and pins, inputs and enable Probe. and assign a pin. Reboot Mach and you should now see a 3d probing tab at the top beside the help tap.

I do not plan on using a probe.  I plan on using a Edge Finder.  I dont think this will work with a Edge Finder.

It works pretty well, I have seen it with my own eyes.  ;)

The wizard I am meaning is the circle centre wizard, it is quite possible that it is not included with the standard Mach instal but it should be on the ftp or the yahoo files if its not. I will have a look when I get home from work if you are not soted by then.

When I go to that wizard hood it looks nothing like that.  Any suggestions?  Maybe you have a higher verison than I do.  I will look around and see if can DL a high verison of this wizard.

Ok due the lack of sleep and being alittle bit rushed I clicked on the wrong wizard.  I have now found the wizard you are talking about.  And it looks exactly like you showed it to be.  Thanks for the help.  I am going to go try it and then prolly go to bed !  Once again thanks for the help.

When you go to the wizards do you see the same as I have in the first image, ie circle centre V1 by German Bravo ??

ahh ok, sorry missed your last post, let me know how you get on. I have not used it as I cant use the MPG to jog but I must modify the screen so I can do so as I think I too will find it a very useful wizard.

It works very well.  I milled a 1" slot in a peice of wood. and put a 1" steel pin in it.  Then i found the middle and it was within .002 of the center if the hole.  As accurate as I will ever need it.  I will be using this alot now that i know how useful it is.  This is the first time ive used the Mill a Circle wizard to.  It worked nicely to.  Saves alot of time when all you want to do is mill a slot or hole or something and dont wanna half to program it.

Thanks for all the help.

Thanks for the info, this has spurred me on to modify the screen so I can use my MPG in the wizard, also I will have to finish my probe/edgefinder now LOL
