Mach4 General Discussion / Cutter compensation

« on: November 21, 2022, 09:07:59 PM »

If I program to use control for cutter compensation I have a couple of issues. The first is that when the program first starts to run it will drive the z axis below the set Z zero. The second is if I put a diameter in the tool chart it will give an offset error or make mickey mouse ears. I have also tried enter a small value in wear and still get a cutter comp error.

This is the second program I have written with the same issue.

Another problem I had after stopping the program is I entered MDI command of G0X0Y0 and the received an error the cutter comp was still active. So I entered G40 on the first line and the G0X0Y0 on the second line. Pressed cycle start and the x and y axis moved as expected but the z axis also moved to -0.06 which was well below the top of the part (note the spindle was about 2.5" above the part when I pressed cycle start). Good thing there was a hole there already.

Mach4 General Discussion / Spindle Brake Switch

« on: June 08, 2020, 12:37:03 PM »

HI All,
I am looking for a way to add a switch to my spindle break that will prevent the spindle from starting while it is engage. I have a linear actuator that is manually controlled and if I forget to retract it after a tool change and start the spindle the VFD faults out. I am looking to add a simple limit switch to notify Mach4 whether or not  it is OK for the spindle to start.

How would you add this to Mach4? Would you need a special LUA script or is there something in there already? Maybe like a door interlock type of setting.

Any help would be appreciated.

Stay safe

Mach4 General Discussion / Override control hardware

« on: September 14, 2019, 12:17:15 AM »

I am looking to add some override knobs to my Mach 4 for Feed, Spindle rpm, and rapid. Is it better to use an encoder of potentiometer type rotating control. What is the best way to wire it and configure in Mach 4?
I am using ESS, and PMDX-126.

Thanks Jeff

Mach4 General Discussion / Lua Error Code on Start up

« on: March 03, 2019, 10:47:47 PM »

I was editing a screen set for Mach4 Mill. And now getting an error when I start up. I have tried editing the ScreenScript.lua but have had no success. Figured I better ask for some help before I really screw it bad.

Any help would be greatly appreciated.

I have attached a screenshot of the error and the Screen Scrip lua file

Thanks Jeff
