Title: Help with duel boards
Post by: AROCKY on December 09, 2015, 10:25:22 PM
Hello

I have a dilema where I run functions such as auto zero, spindle speed, mist/flood, water cooling, etc. Currently I operate all these manually as there is no free pins on my breakout board! I have a cheap breakout board lying around and am thinking of installing another parallel port in my comp and run this board as additional so I can utilize the pins for these functions.

My question - Is this possible?

I have noted that in the ports and pins config in Mach3 it allows for a second port to be selected, is this intended for this purpose? or is there a completely different path I should be looking at to utilise the second port function when adding pins?


Can anyone pass on some info?


Thanks Guys

Hi Arocky,

Yes, it is possible to do exactly as you suggest.

When you purchase the new PCI parallel port card it may be best to get one which has 5 volt TTL outputs (as opposed to 3.3 volt TTL outputs). This thread may be of interest to you https://www.machsupport.com/forum/index.php/topic,11300.0.html
