General Mach Discussion / Re: Name of this controller? Manqls for it?
« on: June 06, 2018, 09:03:27 AM »
Among seafarers, there are those we call Shellbacks who have been formally indoctrinated into the Solomn Mysteries of the Ancient Order of the Deep.
Picture an aircraft carrier, such as the vessel I was on at the time, the ultimate expression of a countries naval power, costing billions of dollars to run and carrying billions of dollars of aircraft, stopping for the day and ceasing military operations to perform these ancient ceremonies.
The naval tradition is simply crossing the Equator while at sea, and the Shellbacks among the crew are in charge with, in my case, thousands of terrified Polywogs about to become men.
Aye, and there are things about which we do not speak.
Among the Shellbacks are those who have been granted the secret knowledge into the ways of Man in the hallowed city of Olongapo and whom are revered by common seaman and landlubber alike in tales of Legend.

Are you a shellback irL?
I got mine on the Kitty Hawk.

I got it now.
I just finished a first-timer scratch build mill so I'm kinda into it.
Can't you just use the jog buttons on your Mach screen?
I made a joy-stick 4-way switch for x-y jogging at the machine, but seperate ON-OFF-ON momentary switches can be used for each axis. If you have spare inputs available, two per axis.

Ahh.  So.
The beige box. No mfr logo. Can you open it and take some pictures of the guts?
Note to self ... Read the manuals and reviews before buying.

Seriously, if you can't find a suitable plug-in for Mach you have little choice but to put a domestic motion controller in there and treat it like a scratch build.
I'm picturing a rectangular sheetmetal box on the top surface to contain the mc and bob.

I have an ESS smooth stepper and C11G BOB.  How do I create more inputs to accommodate that many switches?

If you want discrete inputs, you can use a C10 bob which comes with a db25 plug to parallel port cable and use port 3, and set up the pins as inputs.
The C10 requires 5v supply voltage from external source.
I use a C25 bob plugged into ports 1 and 2 directly, and a ribbon cable-connected C10 on port 3.
The C25 is quirky and I modified mine by removing the input led's.

I use a C10 bob on my port 3 with a short ribbon cable connector and it's fully configurable as to ins or outs and setting common as 5v or ground.
I use it mostly as an input bank for a joy-stick jogger.
Highly recommended at $23

Mach4 General Discussion / Re: Z Axis Homing setting

Al my setting are set under Homing and soft limits.

You should set the INPUTS homing points also.
In my case I have six end switches, normally open to ground and the inputs are pulled up. Z Home  and  Z++ are the same,  X Home and X- - are the same, and Y Home and Y++ are the same.
When homing, the limit function is ignored, after homing the limits are active.  Setting Z Home POS, it homes upward.

Also, have you set the pull-off distance?
With my setup, it is a setting in the motion controller plug-in config, not Mach config.

This is the unit I believe.
Do you have two or three wires?

Note;  Correction to my above post. It was the BOB that had the led's on it, not the Stepper3 motion controller.

here is a diagram for the three wire type npn proximity sensor with a 10k internal pull up resistor.  When measured at rest there will be V+ on the black wire, so you shouldn't hook it directly to an input with a pull up. (will have Vcc on the input pin at rest)
