I also have failed to understand the correct Setup for Ports and Pins when using USB. A return picture for comparison may be asking too much but it sure would help! There are some other iffy-looking connections but I would be grovellingly grateful if someone could compare their working setup with the attached photograph and perhaps enlighten me on what's good and what's not.
I'm guessing the xCM might be Analog and Digital Common. My problem is that I have no way of finding out the meaning of AVI, ACM and DCM and what their connections should be. Looking at the wiring, and referring to the scant information available on line, I have some doubts about the correctness of the connections to the PCB.įor instance, there is a link between the ACM terminal and the DCM teminal which does not appear on the diagrams. What we have is a failure to communicate. I can get the spindle to run under manual control from the front panel so it basically works. In fact there is zero activity between the items. My problem has been the complete failure of my computer to connect and control the drives via the USB cable. Initially I was impressed with the overall build quality, pretty good wiring quality and beefy power supplies and stepper drivers.
I have been trying to connect my Widows 7, 32 bit Toshiba laptop to my new 6040Z (allegedly-) USB controlled CNC machine.
