General Mach Discussion / Re: pocketing and profiling

« on: October 18, 2015, 02:52:21 AM »

It takes some trial and error to initially find the right settings but for inlay work I create one Gcode for the 'pocket' cut on the inside of the line and the Gcode for the 'inlay' flipped and cut on the outside of the line with the line width (being the kerf width) determined in the .dxf artwork. Difficult to explain but try it and I am sure it will make sense. This approach works equally well for laser as well as rotary cutting.

Hi Nick,

My recommendation is to just connect the shields to Earth (a star type earth tag) at the controller end only.

When I was a youngster, ( now retired ) there were " wood burning kits" for kids to use.  The hot end was VERY similar to a soldering iron. Don't know the wattage, but expect it to have been in the 60 to 75Watt range.

Those hand tools are still available and in turn led to homemade versions, the development of the software G-Ray and a great deal of experimentation before producing very acceptable results as shown in this thread. http://www.microsofttranslator.com/bv.aspx?from=&to=en&a=http%3A%2F%2Fwww.microsofttranslator.com%2Fbv.aspx%3Ffrom%3D%26to%3Den%26a%3Dhttp%253A%252F%252Fhobbycncart.com%252Fforum%252F46-234-1

Also since I purchased this mill with a licensed copy do I still need to order my own licenced copy or is it transfered since I'm buying the machine and control?

The official line is that the Mach3 license is non-transferrable. However this is not cast in stone and there are many instances where a transfer of license can be acceptable. Please use the contact form to contact licensing for full details. http://www.machsupport.com/contact-us/

Hi my name is Kevin iv'e been a machist since back in the mid 80s when my father my brother and myself started a company manufacturing medical research equipment. we needed a new CNC machine to make small parts on and after loking around at what was out there decided to make our own

Hi Kevin,

Welcome to the forum.

We look forward to following the progress with your machine build. Please be sure to post some pictures during your progress (we all love pictures  ) in the Show'n'Tell section. Any questions you may have just ask away - best to post questions as a New Topic in the general section.

Go to the Settings screen and click on Set Steps per Unit (bottom left).
Follow the instructions and repeat for each axis - this should tell you the correct steps per unit you should have set in Motor Tuning for each axis.

Sounds good to me. 

I use an external HD to perform exactly this same task.

G-Code, CAD, and CAM discussions / Re: Problem with my X & Y

« on: October 12, 2015, 02:41:34 AM »

There are always exceptions but it is usual to configure a machine’s axes with relation to the position in which the operator will stand.
The axis moving left – right being the X axis and the axis moving toward – away being the Y axis.
The physical direction of each axis is defined in Mach3 according to the direction the tool moves over the work.
The tool movement to the right of the work is +X
The tool movement to the left of the work is -X
The tool movement to the back of the work is +Y
The tool movement to the front of the work is –Y
And just for completeness…
The Z axis movement with tool moving away from work is +Z
The Z axis movement with tool moving towards the work is –Z
And X0 , Y0 is in the front left hand corner.

Please check out the Mach3 Manual for more details. http://www.machsupport.com/help-learning/product-manuals/
