FAQs / Re: Can Mach3 Do PCB Drilling using an NC file

« on: March 09, 2012, 02:45:41 AM »

Hi rcheng111,

No problem.

You could use the free program Eagle and it's associated processor to create both the PCB and the drill file but there are also many other alternatives to choose from.

Here is a link to get you started http://pcbgcode.org/

A possible cause is that you have not declared a feed rate for the G01 move.

Try putting F600 before the G01 move.

Hi jurbanek,

It would help if you could perhaps post a picture showing the stripe problem you are having.

That's good to hear Fred - The CNC Cookbook site is indeed filled with much educational and inspirational material.

FAQs / Re: G-CODE NOT WORKING, JOGGIN IS OK

Hi Intarsica,

From memory the standard Mach install sets jog rates to 80% of maximum. Try holding down the Shift key and then jog,  if this produces problems then you will need to reduce your Velocity settings by at least 20% in motor tuning for your X and Y axis.

You are very fortunate Russ. The work of Marcel is indeed truly wonderful.

Show"N"Tell ( Your Machines) / Laser Lenses.

« on: March 04, 2012, 04:05:26 AM »

Many of the focus lenses used with CO2 and other lasers are of the single element Plano-convex type. As there have been some discussions recently, in various forums, regarding the orientation of these lenses I would like to clarify the situation.

Whilst this type of lens will operate in either direction the focal point will not be as sharply defined unless the convex surface is placed towards the photon source and I have tried to illustrate this point in the following photos. (Please ignore the backscatter from the test lenses as they do not have the customary anti-reflection coatings).

Basically, the tighter the focal point the greater the concentration of photons the greater the power and thus the greater the efficiency.

Hi Fred,

There is lots of useful information on Bob Warfield's site http://www.cnccookbook.com/CCCNCGCodeCourse.htm

A Google search for GCode tutorials should also bring a good return.
