Tangent Corner / Cabin Fever Expo 2014 York PA
« on: April 16, 2014, 11:19:36 AM »
Some of you may know that Mach4 was demonstrated at Cabin Fever Expo in York PA over the weekend of the 12th April 2014

Here are a few pictures of the development team :-

Picture 1, shows Brian in full swing explaining the finer details of the blocking move to be used when attacked by savage monitors.

Picture 2, Steve puzzling over all the lines of code that make up Mach4

Picture 3, Todd waiting for coffee as Brian answers Email.

Picture 4, Paul trying out the 40% power saving claims on the monitors, 2 minuets later he was asleep, we concluded the claim was true

what you are talking about is what lathes with milling do when they do not have a Y axis, most lathe CAM can do XC or polar milling so lathe may be the place to look for code creation.

In lathe mode Mach3 will change tool on a Tnnnn command e.g. T0101 for tool 1 offset 1

Yes and no, Mach3 and Mach4 are closed loop if the external controller supports closed loop.  Using the parallel port nether are.

Yes its possible, not easy but possible, Mach4 will do it much better and with greater ease.

delete the Mach3.lic file from the Mach3 directory and start again making sure you don't have 2 installs on that computer, check using the properties of the Mach3 icon on your desktop for its location on your hard drive.

Yep, got it

You will need a large bin for specials (otherwise known as scrap) a small area for displaying perfect examples, over time the sizes of theses can be reversed.

A swear box with a large capacity, useful for replacement tool purchases.

A swivel chair is always good for the long running jobs, plus a copy of popular hobby magazine.

Tea or coffee making machine, again this can be replaced with beer, wine, etc but only as experience allows.

An understanding wife, girlfriend, partner and bank manager are always an advantage.

You can use subs and absolute code, you just need to use G52 to set the local offset position and then you can use G90 absolute code at the new position

E.g.

%
G00 G90 X0 Y0
M98 P1
G52 X20.
M98 P1
G52 X20. Y-20.
M98 P1
G52 X0 Y-20.
M98 P1
G52 X0 Y0
M30

O1 (SUB)
G00 X0 Y0
G01 Z-1. F100.
X10.
Y-10.
X0
Y0
G00 Z1.
M99
