Homing an axis moves away from home switch!

I have LinuxCNC set up for a 30-year-old 3-axis (XYZ) CNC router machine.

I can jog an axis and the home and limit switches work fine.

However, when I attempt to move an axis, the axis moves away from the home switch and then finally presses the limit switch.

The axes normally move in the correct direction (pressing left arrow moves the X axis left, etc.).

Why is this happening?

I have a separate home switch for each axis.

Each home switch has its own wire leading to the beakout board.

Each home switch is also the minumum limit switch.

I also have maximum limit switches that are all wired in parallel.

Here's the pinout of the input pins on my PMDX-122 breakout board.

Pin 10: E-Stop to PC (Internal, Works great)
Pin 11: Home X and X-axis minimum limit
Pin 12: Home Y and Y-axis minimum limit
Pin 13: Z-axis minimum limit
Pin 15: Maximum limit for all axes.

I know all switches work fine )

My machine is set up so "Home" means the tool is at the bottom-left corner of the table. (Y axis.)

Can you post the ini and hal files.

The machine does not have internet access (I blacklisted e1000e on Debian).

Ubuntu (the PC is dual-boot Ubuntu 24.04 LTS (for everyday stuff) and Debian LinuxCNC) has internet access, but it is annoying to copy the file.

I don't understand why it does not work with just the stepconf config.

Why is LinuxCNC so stupid?

I have the axis travel set to 20 inches in stepconf.

I have the home switch location set to 0.

Why does it move away from zero and toward 20 while homing????!!!

You are not helping yourself with comments like this.

As said already. Post the ini and hal files

Boot into Ubuntu, mount the linuxcnc partition and bingo you have access to the files.

But if you can’t do that what’s more annoying, copying the files or not being happy with your machine ?

If you want to be helped you need to provide the info.

Without the info it’s hard to impossible for those helping and you don’t get the answers you require.
