General Mach Discussion / Re: x axis direction question mach3
« on: March 28, 2019, 11:37:20 AM »
is there a way to change the x axis direction on the screen in mach 3. currently on my screen when I move the x axis in the positive direction  the cursor moves from left to right   but I would like the cursor to move from right to left in the positive direction. I have played with reversing the motors and reversing in homing/limits  and the screen allways moves from left to right? 
X axis moving in positive direction should be left to right - that is the correct convention.
Tell us why do you want to change that as changing to something wrong  is easy.

General Mach Discussion / Re: Another C11G spindle Control issue..
« on: March 28, 2019, 11:21:21 AM »
Spindle Pin 14 - did you tick active low or not?

The 0 to 10 Volts must be measured between 0-10V connector and "Analogue ground" beside it (which is not the same (nor connected) to digital common ground.

(Or try to follow page 9 and 10 of c11G manual attached)

Now a little problem that I have is that I can't seem to enlarge the Mach3 display to fit the screen. If someone could help with this in a simple way it would be much appreciated.

Again help would be appreciated with a nil-low cost program that will allow me to crave photos to wood.  I thank you for your time reading this and look forward to any help that is received.
Hello Nick
1. Enlarging Screen
Go to config | general config
At the bottom under Screen Control
Tick High Resolution Screen and Auto Screen Enlarge
See attached
2. Carving from photo
I would recommend (freeware) Dmap2Gcode & F-engrave and G-code ripper
from https://www.scorchworks.com

God bless

Please download the manual for C11G.

If you can get Mach3 to change analogue voltage from 0 to 10,
using M3 SNNNN command, you can wire the 0 to 10 volts between the ground and the wiper of the Potentiometer - if you already have a speed controller with Potentiometer.

e.g. M3 S24000 gives 10V
and
M3 S0 gives 0V

For DC motor to be able to be controlled by MACH3
you need something like

General Mach Discussion / Re: Limit switches and PWM for laser
« on: March 27, 2019, 07:31:37 PM »
You board has ONLY 4 inputs.
One input (pin 1) must be used for E-stop

Would you sacrifice the use the probe input (pin 4)  so that I can have 3 separate X Y Z limit switches?
If so follow attachment for wiring.
If not you have to combine all X Y Z 6 switches in series into 1 input say pin 2.

The default profile from CNC4PC I think assumes that the spindle will be controlled using Pulse and DIR method.
I don't know why you want the analog 0-10V since you did not say whether you are using a VFD inverter or not and have not named the brand and model.

Anyway, I am showing you how you can get 0-10V - just follow my 2 uploaded attachments.

Mach4 General Discussion / Re: Mach4 Parallel Port Legacy Plugin
« on: March 27, 2019, 07:07:40 AM »
Mach4 printer port (darwin) has some limitations when compared with Mach3 with parallel port
e.g
no Plasma THC
no Backlash compensation
no  threading

If those are no needed as yet, it is OK to use Darwin Mach4 printer port (Darwin) first.
THEN
Save up for
Warp9 ESS which appears to be the most promising motion controller so far.
(Maybe it's better to avoid the USS and ALL other USB based motion controllers.)
ESS should be able to connect to your 1 (or 2 or 3) parallel port Break Out Boards (BOB) so migration from parallel port (Darwin) to ESS should not be too hard assuming you will continue to use Mach4 on Win 7 (32bits).
I think US$25 for Darwin and $180 for ESS is not too expensive.

2000pulse per rev is only correct if you have a 0.72deg stepper motor.
360deg /.72 give 500 steps per rev
4 microsteps then gives 2000 pulse per rev
