SmoothStepper USB / SS and Laptop
« on: February 22, 2012, 04:23:11 PM »
Hello,

I am looking at getting a new computer for my 4x4 cnc router.  Right now I am using a win7 desktop but am planning on switching to a laptop.  Was wondering if all laptops work.  Also what specs should I be looking for?  This laptop would only be used for mach3. 

Right now I am looking at standard 14" screen laptops from mostly Dell.  Looking at right around 6gigs ram.

Also is there any advantage of using Win7 home or Win7 Pro?

Thanks Eric,

Well even when I turn on cutter compensation it does not seem to work correctly.

Here is that program with cutter comp turned on.  And In mach3 I told it the cutter was 0.055" dia.  It cut the part as if there was no compensation turned on.  0.0313" larger per side.

General Mach Discussion / Wear Compensation - Mastercam 9.1
« on: February 15, 2012, 11:22:43 AM »
Hello,

I am trying to get wear compensation to work on my 3axis cnc router.  But every time I turn it on and I 0.01" or -.01" in for diameter wear in Mach3 it does not change the cut size of the part.  I have tried wear and reverse wear in mastercam.  Is there something special you gotta do in mach3 to get wear compensation to work? 

Here is my program:

General Mach Discussion / Re: Mach3 and a Laser.
« on: January 31, 2008, 04:21:15 AM »
to be exact.  I need to be able to engrave steel with cermark spray.  Engrave logo's. 

Now all the laser powersupplies I see say they run off a PWM or 0-5v signal.  The spindle I run atm runs off a 0-10v signal.  Can I run the laser off this 0-10v signal to control the power?

All I want to do is Cut and Mark.  but marking is the big thing.  Cutting would just be a extra.

Anyone have any other suggestions?  Like how do you usually control a laser with mach3?  Right now I have a spindle controlled threw my com1 port.  If I made a second profile and etc.  Say I bought this laser.

how would I go about controlling it?

Also does anyone know a good cad/cam for lasers?

If I understand how these lasers work.  You usually have a table that moves up and down for focus length.  Well my table don't move.  Couldn't I just move the focus lens up and down with Z axis.  Have a mirror shoot the beam down and have the z axis focus the lens to my part.

I am just wondering if anyone has had any experience building a laser engraver using mach3.  Also how hard would it be to have a router/laser into one machine.  Maybe have 2 computers and 1 machine and have a router and laser head mounted on there. 

I already have a cnc router that runs off mach3.  And it dont run all that much.  And we need to get a laser engraver.  And its either spend 10,000$ or buy a C02 laser and put it on my router if that is possible.  Also what kind of software would u use to program for a laser.  Right now I have mastercam for my mills/router and lathes.

General Mach Discussion / Re: Finding the middle of a circle.
« on: May 29, 2007, 04:07:00 AM »
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.
