G-Code, CAD, and CAM discussions / Re: Mach3 G54 to G55 issue

The only thing I can see is you have no M06 on tool 7 in the first profile.

Mach3 will not display the fixture offsets in the correct place due to a limitation in the way it works, the tool will be in the correct place just the graphics are messed up.

If you have mechanical switched it could be you need to up the debounce in config. or it could be noise on the switch wires, they should be twisted pair shielded with the shield grounded at one end only.

Or it could be a loose connection that is triggered by the cutting resonance.

Mach4 General Discussion / Re: Spindle Brake Switch

Yes but with a double pole switch you can signal Mach that the switch is open and in the M3.m1s macro check the switch.

The safest way is to wire the switch into the spindle run relay so it can not energise.

Mach4 General Discussion / Re: EMCO 6P CNC retrofit - M6 Issue

This is a Mach3 M6Start.m1s file for an Emco that I did some time back, you should be able to replace the relevant calls with Mach4 ones and I am sure we can help if you get stuck.

Code: [Select]

    ' new tool required
    If NextTool<1 Or NextTool>8 Then 'valid tool check
      Message("Next Tool out of range")
      Exit Sub
    End If

    ActivateSignal(OUTPUT4)   'rotate Turret

Mach4 General Discussion / Re: Mach4 Macro - Automatically load next Gcode file

Why not do it in g-code with an M98 and the file name, store the programs in the subroutine folder inside mach.

Was the code written for G41 from the start or have you added it later?

Gaining steps is usually noise on the step wire, are you using shielded twisted pair cable on your signal wires grounded at one end only.

Mach3 under Vista / Re: Soft Limits Issue

« on: June 03, 2020, 08:55:44 PM »

Softlimits work off the machine coordinates so if your machine is at home in picture one then switch to machine coords and move to the opposite limits and that will be your min values minus xyz, home should be your max values.

Mach4 General Discussion / Re: Steps per unit output will not change axis Movement

« on: May 29, 2020, 08:45:57 AM »

When using servo motors the steps per is based on the encoder pulses so a 1024 per rev encoder would be 4096 steps divided by your pitch and drive ratio.
