General Mach Discussion / Re: Need help with ports and pins

« on: March 24, 2017, 03:08:36 AM »

The Port 1 Pins Current State Led's don't always work as expected so they should be ignored.

If Output#3 LED flashes then that is OK.
When you measure the output voltage on Pin 17 the voltmeter should be connected between Pin 17 and Pin 25 (or any pin between 18 and 25).
Check that you have not allocated Pin 17 to any other functions within the Mach3 set-up.
Check that Signal GND (LPT Pins 18 to 25) is connected to GND on your breakout board.

You cannot duplicate pin number functions without causing a conflict. If you are using Port1 Pin2 as your Spindle Step pin then you cannot also use Port1 Pin2 for Output#1.

You have probably seen this already but by far the simplest solution to using PWM laser power control is described here :  http://www.cooperman.talktalk.net/files/27_files/Page1020.htm

I now understand about the rem's 

The only thing that the M10 / M11 are required to do is ActivateSignal(9) / DeActivateSignal(9)

Hi Bruce,

The taig.xml is not configured with any data so it is definitely not that one which you should be using.

Your Mach3Mill.xml runs OK here and there does not appear to be any problems (although you have an unusual pin allocation for the Step and Direction signals).

Does you machine move if you enter G0 X5 in the MDI (Alt-2) line then press return ?
Does the X axis DRO now read 5.0000 ?
Do the DRO's change when you use the keyboard arrow keys ?

General Mach Discussion / Re: Harbor Freight Mini Mill Relay Spindle Motor

« on: March 22, 2017, 03:09:00 AM »

if i were to put a relay in series with the DC Motor would MACH3 turn the relay off and on

You would need a relay which has a coil capable of handling the current of the DC motor.

I assume its a 5 V from MACH3.

Not sure what you mean by this

Set Output#1 to the port and pin number which is connected to your laser trigger. Set active High / Low, as appropriate.

This Gcode will turn on Output#1 and activate the pin number you have specified above.

G0 Z0
M11P1
G0 Z1

(the G0 Z0 is only there to make sure that G0 Z1 is an actual movement as far as the DRO is concerned)

Can you explain what you mean by "when I look at the m11 m10 commands most of them are rem out"

Mach3 under Vista / Re: Scripter Compile Error

« on: March 22, 2017, 02:34:02 AM »

Hi Jay,

It's a text file so you can open it in notepad.

Correction to my earlier post as you may be using a profile other than Mach3Mill...

Bottom right of the main screen is your Profile: the M3.m1s file you need to look at is in the  Mach3 / macros / <your profile> folder.

Mach3 under Vista / Re: Scripter Compile Error

« on: March 21, 2017, 11:35:01 AM »

Hi Jay,

In your Mach3 / macros / Mach3Mill folder is the file M3.m1s

The contents of that file is usually   DoSpinCW()

If the contents of that file have been changed and the syntax is incorrect then Mach3 will report the "Scripter Compile Error, In:M3.m1s" when M3 is called in your Gcode or MDI instruction.
