Hi,
I've recently changed my CNC computer and installed a motion controller UC300-5LPT as well. I'm using a homemade gantry router type machine.
I have imported my .xml profile from my old computer but the CNC is not behaving as it did before.
When I try to do a "Ref all Home", the Z axis travels up to it's top limit switch, and then the Y axis starts, when it gets to it's limit switch, it over rides it and keeps going, like it doesn't notice that it has been triggered.
I can back off it with the jog button, and it travels rapidly away from the switch. Before it would travel slowly when it was at this point, and I would have to reset it again when the switch was un triggered.
I was sure this is a simple problem to do with active low/high settings so I have adjusted everything I can through trial and error but I can't seem to work it out.
I had to go through the settings when I fitted the motion controller and change them to port 2 instead of port 1, but apart from that I don't think I have changed anything from my original machine set up.
I only have a very basic grasp of what all the ports, inputs and output configurations in Mach3 are about as you can probably tell.
I'm a bit stumped, can anyone help?
Thanks
Joz
