General Mach Discussion / Re: Need help setting up Mach 3 for my table.

« on: May 25, 2013, 01:01:06 AM »

Hi Tony,

Basically, when you open Mach3 the title bar will show "Mach3 CNC Licensed To: <your name>". If it shows something other than your name or the unique serial number which you purchased then it is a pirate license.

Hope this helps.

Hi Guys,

It is usual practice to fit a reverse biased diode across a relay coil in order to suppress the high voltage spike (which occurs during the magnetic field collapse) when a relay is switched off. (Just for example;  http://www.hobbyprojects.com/the_diode/diode_protection_circuits.html)

Thanks for the answer. But once I could use Mach 3 on a laptop. Maybe there's something about laptops hardwares.

Could be that your original laptop had a 5 Volt TTL parallel port and your new laptop has a 3.3 Volt TTL parallel port - not all stepper motor controllers will accept the 3.3 Volt standard.

Hi David,

Welcome to the forum.

Unfortunately, licenses purchased with Chinese machines almost all turn out to be pirated but you can check your licence by contacting Scott  at license@machsupport.com. he will be able to verify it's authenticity.

Steve,

It's a long shot but assuming you are using 'normally closed contact' limit switches then check that there is not a wire off (disconnected) or that one of the switches is not stuck open circuit.

Hi Daryl,

Open LazyCam then open your .dxf there.

There is a LazyCam manual in Members Documents which gives details of it's use. http://www.machsupport.com/forum/index.php/topic,12078.0.html

Edit; As Brett has said LazyCam is basically dead and there are much better CAD/CAM products available but it works OK for simple .dxf drawings but the more complex they become the longer it takes to complete the job.

Now give me directions to the thread that discusses a touch block for zeroing axis.

DMF,

If you return to the main page and do a search for Auto Tool Zero you will find many threads there.

General Mach Discussion / Re: SIZE

« on: May 19, 2013, 09:16:38 AM »

Quick question is, in case I switched from metric to inches after I set MACH to metric in the original config. which I do not think I did. The vid said not to do it but it can be done. How does one do it before I reload Mach and start and config again.??

Do not change the Mach3 configuration to switch between Inches and Millimetres use the G20 / G21 commands, as appropriate, at the start of your GCode file.

I set Vcarve to a 5" on the X AND 4" on the Y When Mach cut the plexiglass which it did the size came out on the plexy 1" x 1" aprox. It all sized down

Could it be that you have set your 'Steps per Unit' incorrectly in Motor Tuning ? (if you input G0 X10 in the MDI screen does the X axis move exactly 10 inches ?)
