General Mach Discussion / Re: Computer problem after running mach3

Hi Nigel,

Sorry that I cannot suggest a solution.
I am sure you will get there in the end but just how complicated can things get ?

Hi Mark,

Thanks for drawing our attention to a potentially dangerous situation.

I agree with Jeff's comments 100% here.

If it is possible for something to go wrong then sooner or later it will happen and personal safety should always be paramount in our minds at all times.

Hi Nigel,

I just made a special trip to my workshop to check the PC connected to my router which uses two parallel ports.

It has Award BIOS and under;
Integrated Peripherals
Onboard Super IO Device
Parallel Port mode

It allows selection of the onboard pp mode between ECP/EPP/SPP/ECP+EPP

My second pp card, as mentioned earlier, was set as EPP 1.9 during install.

Don't know if this helps.

Could this be related to the same problem we have just started to see occurring with Mach3 Mill ?    http://www.machsupport.com/forum/index.php/topic,18990.0.html

Hi Nigel,

This is totally untested but you could try uninstalling the device then - Control Panel / Classic View / Add Hardware wizard to install it again, inserting the disk when prompted. (if you remove the PP card and insert it in another PCI slot it should be seen as a new device without uninstall).

Hi Nigel,

You are correct, I was wrong   

I just checked the G540 data and yes it does require the EPP mode to communicate the stop / reset in Mach.

When I last installed a parallel port card the ECP / EPP option was a choice during install but I used an install disc that came with the card. I don't know if the standard windows installer will give you the option.

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. 
(Who knows, you could just be lucky).

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.
