Hi,
I have just purchased a Shopbot CNC router that was setup to run on Mach3 in lieu of the Shopbot operating software. The previous owner disconnected all the homing and limit switches on the machine when he converted it to Mach3.
I have watched the videos on the Mach3 support on limit switches, homing etc.
If I hook up couple of wires to one of the inputs of the CNC4PC C-10 Breakout board it works as one would expect (i.e. normally open or normally closed) getting the desired lights on the Mach3 diagnostics screen. However, if I hook up the Proxmity switches that came with the Shopbot router the LED on the Proxmity switch lights up when the switch comes with the designated gap of the proxmity plate but does not send a signal to the control to disable the axis movement. My assumption??? is that being the LED light on the Proxmity switch comes on they are working correctly. Maybe, they need a different activation voltage etc.
?
Any of you guys out their with converted Shopbots that may have already encountered this issue and found the solution.
Also, my pulse frequency on the diagnostics page is reading around 45K instead of 25K. Any ideas on how to correct this? I ran the Driver test and got an excellent report but got a message saying that the pluse rate was too fast.
The machine is running but just wanted to fix this issue.
Any help would be appreciated.
Thanks,
John
