CNC test / prototype macro testing boards
Posted: Sat Mar 23, 2019 12:52 pmI have a spare uc400eth and given I spend evenings doing macros wizards and the occasional plugin, I've been dabbling with the thought of making a lpt test board / emulator, hence this is what I came up with.
PCBs are so cheap to have manufactured now I can't see the point in milling them any more.
Like I design most of my PCBs given you end up with more boards than you may need, I try to design the multi purpose .... Sometimes this means I make them mirrored so I can install components both sides of the PCB... Like I did with a steering wheel that had button controls and paddle shifters..... And in this case I designed the boards with jumpers so that the buttons can be set as active high or active low to emulate no or NC switches and inputs.
There are also a couple of dedicated test points which I'm awaiting some loops to install in so I can connect oscilloscope probes to or frequencies counters etc and made the programming of macros, wizards and plugins a little more easy to do sat away from the machine or away from someone you may be trying to help.
Presently trying to help someone with an ATC that uses a Geneva drive and a single rotation pule index per slot and another per ATC revolution that uses the constructor macro to home the ATC and does various other checks and will move the ATC in the shortest direction to the required tool. I'll post it in the toolbox when done.
