General Mach Discussion / Re: Tool plunges into project too deep

« on: June 05, 2017, 03:52:34 AM »

As you suspected, there is nothing wrong with your Gcode - it runs just fine here.

Check that your cutter is secure in it's collet and not moving.

When the problem occurs stop the work and check your Z zero position.
If Z zero is now below the work surface a likely cause is loosing steps on the +Z travel - try reducing your Z axis Velocity and Acceleration settings in Motor Tuning by 50%, save the changes. Then, does the problem still exist ?

If you zip and post your Gcode file then that can be checked and at least rule out one possibility.

Mach3 under Vista / Re: Driver Test Will Not Work in Vista

Have you followed the advice given in this post ?   http://www.machsupport.com/forum/index.php/topic,2385.msg14328.html#msg14328

Does your PC meet (or exceed) the minimum requirements ?

Requirements if using the parallel port for machine control:
Desktop PC (Laptops are not supported) with at least one parallel port
32-bit version of Windows 2000, Windows XP, Windows Vista, or Windows 7 (64-bit versions will not work)
1Ghz CPU
512MB RAM
Non-integrated Video Card with 32MB RAM(Large G-code files, especially 3D files will require a video card with 512MB RAM or higher)

It is possible that you have a corrupt installation, in which case try deleting the Mach3 folder and reloading Mach3 from scratch (make a backup copy of your original Mach3 folder first).

You need to connect a protection diode across the relay coil and also check the model / rank of the PC817 opto as their maximum drive current rating varies from 2.5 to 30 mA and this will determine the type of relay you could use.

Maybe better to purchase a ready-made cnc relay board ( ebay from China ) ??

Hi Shanren,

I think that line of code should read :-

Code: [Select]

Do While Getvar(3) < 360.000 * Getvar(8)

Hi Jeff,

Perhaps take a look at and run some of the practice Gcode files in the .zip file here: http://www.machsupport.com/forum/index.php/topic,18345.0.html  - it may help you to get to grips with using Mach3.

General Mach Discussion / Re: Z Axis Brake - AC Servo Motor - Let drive do it or use Mach3?

« on: May 28, 2017, 01:45:15 AM »

It was common for a spindle brake to be used to enable faster tool changes to be made on the ATC equipped machines but changes to certain industrial regulations have now made cutting device brakes mandatory on some machines (typically, circular saw benches) - perhaps check the regulations in your country.

I would be inclined to let the drive control the braking.
