General Mach Discussion / Hi Guy's

« Last post by RuddyCrazy on July 29, 2025, 03:05:59 AM »

Well I first built my CNC back in '11 and ran it with Mach3 on XP, well doing my first circuit board got 95% done then the computer decided to die on me then 64 bit came along. So moving forward to today after trying a few control boards finally got one that works.

Now this board to my surprise only has 4 inputs and no socket to connect with the ground of my cnc, so getting my limits to work has been very troublesum to say the least and still no joy.

Anyway calibrated all the axis using my DMM over 2mm and got each axis to 0.01mm, did a few checks on the X axis and all appeared to be true. So made a gcode to drill some mounting holes and found 100mm was actually 102mm. So more calibration will be needed.

Now what made me give up today after running the CNC and stopping the code the X axis when I write Ggode just won't show up in the Mach3 screen did several reboots with no joy so not sure why it is doing this. Now when I do G01 Z 10 it shows when I do G01 X 100 no G01 X is shown.

Mach4 General Discussion / Re: Y axis stepper not smooth / missing steps?

Hi,
you say the data cable?

Have you trued swapping the stepper drive. I rather suspect the fault is the stepper drive rather than mach or the PC, but you need a test
to confirm that. I'm not sure that swapping the data cable adoes that.

I swapped data cable inputs to the X and Z motor drivers. Problem was on Z.

Hello everyone, does anyone have a script for finding the edge of the workpiece in 3 points and rotation like in this video

General Mach Discussion / Re: Mach3 will only home Z axis

« Last post by barmanlasting on July 25, 2025, 03:37:05 AM »

It sounds like a config issue. Since Z homes correctly, the hardware is likely fine. Check these:
Reverse motor direction (if jogging moves opposite) in Motor Outputs.
Home Neg setting in Homing/Limits — only enable if axis homes in negative direction.
Make sure limit switch inputs aren’t shared or misassigned.
Disable soft limits temporarily while troubleshooting.
The mirrored cutting confirms axis direction is reversed. Fix that first, then recheck homing.

Hi,
I very much doubt that its a problem with your PC or Mach. The fact that you transfer the cable and the fault follows the cable suggests that the stepper driver is faulty.

Whatever you do.......don't do a scatter gun approach, it seldom works and more often than not you introduce a second problem and that becomes very VERY much harder
to diagnose. Try swapping the stepper drivers between axes. If the fault follows the driver, then the driver is faulty.

Mach4 General Discussion / Re: floating head for plasma table

« Last post by Tweakie.CNC on July 24, 2025, 07:36:40 AM »

Hi Don,

You need a carriage return at the end of your GCode file. Just add the character  %  as a final line.

Mach4 General Discussion / floating head for plasma table

« Last post by Don C on July 23, 2025, 03:44:58 PM »

This is the gcode I am trying to use but it doesn't like the last line and doesn't show up in the screen.
g031 z-8 f20     " probing"
g092 z0          " zero z axis"
g0z1.71          " running my z to cutting height"
g092.2 z0        " rezero my z axis"

any help would be appreciated

Mach Screens / WX4.Set Screen

« Last post by tbadger on July 20, 2025, 03:19:35 PM »

I see in many online demo and/or tutorial videos that the wx4.set screen is a light grey background, which I like. But the version of wx4.set I'm using is the darker grey. I do see that the Engrave_Marking.set screen is the light grey screen. Where do I find the light grey wx4.set screen?  In the demo for the Touch Module Mach 4, for example it is a wx4.set screen in light grey. Is it because it was modified by Warp 9?
