General Mach Discussion / Re: Looking for good DIY controller kit supplier
« on: November 28, 2020, 01:45:53 PM »
The BOB that I use is perfectly suitable for a beginner and intermediate user.
Nothing special on it. It has a possibility to "control" 5 stepper motors or 4 motors + spindle.


As you can see from schematic, if jumper is placed on dedicated pins it controls the relay which can be used for switching spindle On/Off. PWM is available at the terminal P1 buffered from pin1 of LPT port and as 0-10V at dedicated output near relay output.
So it is Mach3 that controls spindle THROUGH BOB  ;D

Another thing, this BOB needs two power supplies. One 5V connected to PC 5v and PC GND and a second one, 12-24V (if stepper supply is not higher than 24V it can be used), for input side (Home/Limit/Probe).

Chinglish? Attached manual is quite easy to understand.

Just to tangle the strings a little bit :)

Controller is, in case you are using parallel port, your computer running Mach3 or similar software which generates Step/Dir signals. In case you are using USB or Ethernet devices, these are controllers as they are generating Step/Dir pulses derived from data that your computer sends in form of PVT (Position Velocity over Time).

BOB: in case of parallel port, a dumb piece of electronic circuitry for interfacing between parallel port and motor drivers and various switches (Home, Limit, Probe, ...). In case of USB/Ethernet, those controllers are BOBs at the same time.

Mach3/4 are open loop controlling programs so you can not use encoders that are mounted to the motors.

If you want to use MPG with Mach3 without external controller, you will need a second parallel port and some "brains" to be able to use it (I do have it on my machine).

Encoders for what purpose?

Mach3 running on a bit older computer with Win XP, or as a last instance Win 7 32-bit

If you want to stay on cheap side, buy TB6600 drivers and 5 Axis Mach3 breakout board (LPT) in well known Chinese supermarket.
My homemade CNC ruter has that configuration and cost for the above was cca. 40€. Add ti that a power supply and you are good to go.

Strange :(
Did you install Mach in the default folder C:\Mach3 or somewhere else?

General Mach Discussion / Re: Mach3 combined Tool and Work Offset probes
« on: November 11, 2020, 04:14:27 AM »
Try to find Big-Tex tool setter screen set.
There is the exact functionality that you are looking for.

Initial setup: Use your ruby tipped probe for initial setup, machine will first touch off your stock, then it will travel to fixed probe location and touch off the plate.
Change the probe with your first tool.
Zero tool setup: machine will touch off fixed plate and you are good to go :)

For all subsequent tools, only use Zero tool setup button.

As you will be using touch probe, set plate offset to zero (0)

Scripts that are behind these buttons work in metric and imperial units.

FYI Fixed probe location coords are in MACHINE COORDINATES so your machine should be properly homed.

If you have a line then your laser is out of focus.
Move your laser up/down or move your material accordingly.

Mach4 Plugins / Re: Plugin for Mega 2590 Ramp 1.4 running GRBL

Why you want to write a plugin for Mach4(3) to "degrade" it to an ordinary G-code sender?

You should look in Mach3 General settings:

Just to conclude this:

I've changed the confuzer :) and no more "gained" steps.
