Mach 3 with usb controler
« on: May 10, 2019, 02:30:16 AM »
Good morning
(I'm a newbie)
I know this is not a forum for chinese cnc's. I just can not find help anywhere.
I'm using cheap 3040 cnc router. The usb controler is bl-usbmach v2.0 d1712 . The controller has a probe for z auto tool zero wich I cannot get to work.
I have done the following:
Traced the wires to the controller
Check the voltages (5v) on the point where wires terminate
When touched together the input on the board change.
I have programened the macro
Set the probe setting to active on inputs
I presume being Usb controller no lights on diagnostic screen lights up at all so I cannot see if the program see the correct pin for probe.
This happens:
When the outo zero button is clicked the z axis moves but does not react to the contact on the probe.(does not stop)
Is there any way that I can detect where my usb probe pin go into the Mach3 software.
Any help will be apreciated
Regards
Cobus
