Hi Guys, this is my first post so be kind please!!
I am currently rebuilding a Newing Hall Millgrav to run from Mach3, with 4 axis control 4th being a rotary head.
I am using the Smooth stepper and high speed spindle and inverter, butů having read the threads on many forums I have made significant EMC shielding arrangements and decoupling with mains filters and moving the inverter as far away from the SS as physically possible,, we will see later if it is enough.
My question is about setting up the hand held pendant using the SS and port two, and three My pendant is identical to the circuit described here http://www.markusmechatronics.com/HandradAnschluss.jpg
On the SS pin functions page I can see the two lines port 3 changing state as I turn the hand wheel, also I can see the lines on port 2 change as I move the switches, I have configured pins 2~9 as inputs with connection 14 as above high so switches pull up lines as the switches rotate.
But how do I configure Mach3 to recognise these inputs and do something useful with them
I have tried to find the information on this site but i would be a very old man if i read every thing.....i am not too young at the moment either!!
Many thanks for your reply's
