Hi Stew,

Just my opinion...
Looking at your .pdf you must use fully supported rails (unless they are upwards of 25mm diameter) otherwise you will regret the flex. Ballscrews are good but remember that they can backfeed particularly on the Z axis so if the motor is disabled a brake can be useful.

I look forward to seeing Scrappy MkII.

Mach4 General Discussion / Re: M codes and mach4, is there still a hesitation same as m3? (Except m10/m11)

« on: October 18, 2015, 03:01:46 AM »

Hi Rob,

If it's any help, the Mach4 equivalent to the Mach3 M11Px/M10Px commands are...

M62Px turns Output# x ON
M63Px turns Output# x OFF

There are no delays associated with these commands as they take effect coincident with axis movement.

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

General Mach Discussion / Re: Best digitizing kit?

« on: October 15, 2015, 01:47:28 AM »

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/

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.
