General Mach Discussion / Re: 3D-CAM needed

Personally I think MeshCam is pretty good value for money but you may also like to check out DeskProto.
Both have trial versions so you can 'try before you buy'.

Hola Ninus,

Mientras objetivos, de cada eje se mueve para disparar su interruptor de casa, entonces retrocede lo suficiente para restablecer el interruptor (que es entonces su posición inicial).
No hay manera de ajustar la distancia del eje retrocede el interruptor (que sólo se mueve hasta que se restablece el conmutador) que es la forma Mach3 ha sido diseñado para trabajar.

General Mach Discussion / Re: I can only see 2 decimal places on feedrate window

« on: January 25, 2013, 03:49:41 AM »

Hey Tweakie, 3 dec, places on the manual screen and the auto screen but when I press cycle it goes to 2 dec, places.
First off it would be nice to see the feed you asked for and second I am still having problems with the feed rate in inch/rev so I need to see when I ask for .015'/rev I only see .01

Hi Ray,

It's all Daves's fault 

Attached modified .lset file (I am no expert at this so hope it works OK).

General Mach Discussion / Re: delay in PWM pulse (LaserMode)

Hi bdn,

Fortunately, I have not had any problem with EMI radiation but my tube is mounted within an aluminum faced enclosure which is grounded to the machine frame and in turn bonded to Earth.

I am not sure that wrapping the tube with foil would be such a good idea but it would be nice to see some pictures of your setup / layout etc.

General Mach Discussion / Re: spindle relay

Hi Rhys,

That's good news, I am pleased that you have got it working OK.

(It's possible that Pin 1 of the LPT parallel port somehow got hung up and was not toggling on / off then restarting the PC cured the problem).

Hi Ron,

If you post your question as a new topic in the General section I am sure there will be some quick responses with suggestions that should resolve your problem.

Hi Rhys,

Obviously, if you are connecting your relay between Pin 1 and GND and using Output#1 for the switching then this Output# has to be configured for Active High (as you have in fact done).

The only thing I can suggest is that you check your Mach3, Ports & Pins configuration to make sure you have not used Pin 1 anywhere else (for any other functions) and created a conflict.

General Mach Discussion / Re: Changing computers

Jim,

I vaguely remember something that came up years ago where a PC, that had been previously used with a printer (connected to the parallel port) still had a document waiting in the print queue.

Windows, bless it’s little heart, chose every quiet moment to try and communicate with the now non-existent printer thus causing problems with the logic state of some of the parallel port output pins.

Just maybe, perhaps ?
