General Mach Discussion / trouble with touch probe - Port 1 pins current state not showing (cnc 6040)
« on: November 25, 2019, 08:11:10 AM »
Hi all 
used many hours and now I need help! I've got a CNCz 6040 China Machine, Mach3 and a windows 7 computer.
I can move my cnc, run programs and stuff- spindle works, but when I go to Mach3 Diagnostics there are no green lights showing at Port 1 pins current state? How is that? I ran a monitor program to check my ports activity and could see there were some ports that were red and some were green.
Well all this began because I wanted to use my touchplate probe... I can press the auto tool zero button- but I doesn't stop it movement down the z-axis when it touches the plate. BUT----I can only use the auto tool zero if I have my active low unchecked- as soon as I check the active low setting in ports and pins input for the probe it doesn't work. I can see the digitize light is green when active low enabled. And it doesn't flash or turn off when i test the probing plate. What is wrong? Could it be a missing ground connection in the controller box for the probe? Or electrical noise? Or my setup? A bios thing with printer port?
I know the CNC 6040 are not the best built machines, but it is all I could afford
I hope I dont need to solder stuff and rewire, as I am not so proficient in electrics.
Kind regards
