Turn off the limit switch signals in ports and pins and see what happens when you just have the home switches enabled.

Get into the habit of using the "Input +" button then it just updates the current value by the amount you enter in the box, so if you need to adjust by .001 or -.001 enter that in the box and click "Input +".

The worst you can be out is .001

Have you got good earth's?

Is the PoKeys in a steel earthed box?

What type of switches are you using?

Do you have power wires mixed in with the home switch wires?

Are you using shielded cable for the home switches?

General Mach Discussion / Re: Mach 3 Soft limits problem (I know, I have seriously tried everything, 5 days)

The first thing to do is make sure you do not have any axis reversed, if you do on steppers swap 2 wires on 1 phase of the motor and clear the reversed tick in homing and limits, do this for all reversed axis. Servo systems its an option in the drive or 3ph AC servo motor swap any 2 of the 3 motor wires. DC servo swap the 2 motor wires around.

Once this is done make sure machine homes the correct way, on a mill this will be table moving to the front and left and z moving up.  Router, spindle to rear right end and Z up, this point will be machine X0, Y0, Z0.

1. Home the machine.

2. Select Machine coordinates, Red ring around button when machine coords shown.

3. If Z axis can move up a small amount this will be your Z max value, then Jog Z axis down to required position. Note the DRO value this will be Z minimum.

4. If Y axis can move to the back a small amount this will be your Y max value, then Jog Y axis forward to required position. Note the DRO value this will be Y minimum.

5. If X axis can move to the right a small amount this will be your X max value, then Jog X axis left to required position. Note the DRO value this will be X minimum.

6. Set your slow zones speed to 20% and the length at 2" or 50mm for a start then adjust it up or down to get the minimum distance to a smooth stop.

If any axis is reversed the values will need to be reversed to.  Better to not have reversed axis.

Mach Screens / Re: 1 Axis touch screen design

I am not sure what is going on, it works fine here but I will check it on another PC.

Check you have these settings in general config set.

Have a look at this, its one I did a while back it was for an 800 x 600 screen size, I have stripped all my custom stuff out of it but it works and you can put your code in the start button to do whatever you need.

Extract the Mach3 folder from the Zip file and drop it over your Mach3 folder to merge them together.  Run Mach3 loader, ChopSaw should be listed.

It only acts as a keyboard input for the length the rest is up to you,  the length is stored in UserLabel1 so you can get at it with something like this in the START button VB code :-

length = Val(GetUserLabel(1))

No warranty given or implied, if you loose bits its your fault as its just a keypad right now nothing more.

If you need mach3/4 to control the spindle speed then its complicated if you only need the spindles to run at a fixed speed and Mach turn them on and off its easy.

Screw compensation is per motor not per axis so each screw can be calibrated individually.

You can start and stop many spindles, but you only have one 0-10 volt output so the two spindles would need to share the speed signal and be tuned to the same rpm.  Matched spindles would not be a problem.  if you wish to run one then the other that should not be a problem with some change over relays.
