General Mach Discussion / Re: How to wire proximity switches

« on: July 24, 2011, 01:41:27 AM »

I think most proximity switches can handle 12 volts (think I read that somewhere). There must be a way to test the switch to see if it's NPN or PNP? 8 switches at $75 each isn't going to happen, must be a way to try and wire up one switch as a NPN and try it, if it doesn't work then it must be PNP?

Sound like an excellent way to make expensive smoke.

Hi Nigel,

Exactly as Hood said. 

(It will show as 0xE800 and this just indicates that it is in hexadecimal notation).

Hi Nigel,

ECP will do just fine.

Go to the printer port properties in device manager to see the port address (typically 0378) that you need to enter in Mach Config / Ports and Pins / Port#1.

Very good suggestion and really great for X and Y probing moves but it may be a different story for a -Z overtravel.

The info presented in this document may be of interest to you.  http://cnc4pc.com/Tech_Docs/C10R10_USER_MANUAL_V2.pdf

You need to establish the voltage and if they are NPN or PNP. If this information can't be determined then it may be wise to replace then with new parts of known specification.

Hi Alex,

Welcome to the forum.

If you click menu  Config / General Config then set the "IJ Mode" to the opposite of what it is currently set to - that should cure it.

Ernie,

Just tried it again and it is OK.
Perhaps reloading Mach may cure the problem you have with your spindle speed DRO.
