In the Mach4Mill \ Backups folder see if you have an Machine.ini file which is dated before the bad shutdown - if you have then try using that and see if it resolves the issue.

Hi Martin,

If you have a problem which directly relates to Mach software then I am sure we could help you but Gnexlab controllers are perhaps stretching it a bit.

General Mach Discussion / Re: Phantom Limit Switch

« on: March 17, 2016, 10:46:34 AM »

It’s impossible to be absolutely sure but from what you describe (having ruled out vibration) it is more than likely electrical noise from the VFD being picked up from the limit switches / inputs wiring (including e-stop, touch probe, etc.).

My opinion which is basically the same as others have said in your earlier thread…
If you haven’t done so already, create a single point Earth at the controller, connect this point to the incoming Earth and connect the shields of all inputs cables to this one point (leaving the other ends of the shields unconnected. Re-connect 0.1uF ceramic capacitors between each used input to the BOB and the single Earth point.
The wire from the VFD to the spindle motor also needs to be shielded and again the shield is connected to the single point Earth and left unconnected at the other end.
If found necessary, re-route the wire from the VFD to the spindle motor separately to the other cables. Check that you (or the Chinese) have not created any GND loops or Earth loops in any of the wiring (these make wonderful antennas).

Hope this helps,

Tweakie.

An option perhaps worth considering ? http://cnc4pc.com/motion-control/motion-controllers/smooth-stepper/c25-smooth-stepper-terminal-board.html

if i was to go smooth stepper i could use more than one breakout bored for auto tool change and other stuff

Mach4 General Discussion / Re: Mach4 Spindle setup

« on: March 16, 2016, 12:43:30 PM »

As you have started a new thread I have closed the previous thread to avoid duplication of answers.

Example Scenario: If i set min spindle speed to 0, and Max spindle speed to 5000, and the Max Motor Speed to 3600. will mach figure out how much voltage (between 0-10V) to send the vfd using some formula and the 5000 and 3600 values from the Max Spindle and Max Motor Speed, if i command an m3 s2500, or m3 s950

Mach4 does not in itself send a voltage (between 0-10V) to the VFD.

The frequency output of your VFD and thus spindle speed, is determined by a 0-10Volts input. This 0-10Volts is generated by a digital to analogue converter which is part of your C32 BoB. This voltage is in turn derived from the PWM signal that is produced by your ESS. The range and scale of this PWM signal is determined by your Mach4 spindle settings and the appropriate S#### command which are then sent to the ESS.
