Long time user of Mach3 but new to Mach4.  I keep seeing references to the Mach4 "Customization Manual" in the Operators and Scripting manuals.  Where can I find this? ???

Thank you for the usefull info.  I am using a PMDX424 motion controller for this project.  Perhaps I will post something on their forum and see what they suggest.

Well I just measured the speed of the Z-axis cranked all the way up and it goes about 250ipm.  There is a hard stop we use for grinding up to a shoulder of a c'bore to prevent the wheel from crashing into it. 

Here is a picture of the current control.  It has an upper limit and lower limit setting for the stroke.  It works fine, but I would like to be able to program the machine to rough multiple holes if I have a bolt pattern to grind.  I would need the Z to return home for the move from hole to hole.

Mach4 General Discussion / Controling pneumatic Z-axis?
« on: May 02, 2016, 11:54:09 AM »
I am in the process of re-retrofitting a Jig grinding machine I did a long time ago.  The machine is sort of a hybrid between the old control and Mach3.  Mach3 controls the X,Y and U (wheel outfeed) Axis.  The old control still handles the Z axis which is pneumatically driven with glass scale feedback.  I would like to take control of the Z in Mach.  This axis does not need to be precision controlled, I just need to be able to set and upper and lower limit so the Z axis will reciprocate between those limits.  I have done something similar in LinuxCNC using a Moog hydraulic servo valve with glass scale feedback to control the position of a hydraulic cylinder, but I have not done this in Mach3 or Mach4.

I am thinking I should take control of the relays that operate the pneumatic solenoid and use a script to monitor the position of the axis.  Once the position hits the upper or lower limit it would activate the relay to change direction.  Does this sound feasible? Is there a better way to do this?

 ;D success!

  I shut my system down, double checked all connections, booted back up and single step/multistep worked with the mpg. Not quite sure what the problem was. I was stuck in velocity mode for some reason.  Thanks for the Help! :D

I see mpg window, I flip through the different jog modes, but x1 x10 and x100 do not change anything?

All jog modes give me the same result. I look at the function of the brain and I can see it switching from x1 to x10 to x100. It does not jog any different though.

Arturo,
I have configured the x1 x10 and x100 as shown is lpt2 Mpg-2 setup manual under general configuration screen.

X1     is .0001
X10   is .0010
X100 is .0100

Hello,
    Trying to Jog with cnc4pc mpg-2 hooked up to lpt2. It moves all axis but I cannot adjust the increment it moves per click of the mpg. x1 x10 x100 are all the same amount no matter what I do.  Seems like I am stuck in velocity mode or something.

Any Ideas? ???
