Re: OPCON and USB-BOB
so an 8 switch joy stick would be used? is there such a beast?

Re: OPCON and USB-BOB
It might be harder to find an industrial joystick with octagonal gating but it is really easy to find arcade sticks with interchangeable gates. To me, the main challenge would be writing the PLC such that two jog button inputs translate to the appropriate diagonal jog button input.

Re: OPCON and USB-BOB
we already have diagonal on the VCP, one button for each diagonal. so that is not an issue , no need for two inputs on at same time.centroid467 wrote: ↑Tue Apr 02, 2024 9:24 amIt might be harder to find an industrial joystick with octagonal gating but it is really easy to find arcade sticks with interchangeable gates.

Re: OPCON and USB-BOB
I'm just saying that it might be easier to have two inputs on at the same time than to find a suitable 8 switch joystick.cnckeith wrote: ↑Tue Apr 02, 2024 2:00 pmwe already have diagonal on the VCP, one button for each diagonal. so that is not an issue , no need for two inputs on at same time.centroid467 wrote: ↑Tue Apr 02, 2024 9:24 amIt might be harder to find an industrial joystick with octagonal gating but it is really easy to find arcade sticks with interchangeable gates.

Re: OPCON and USB-BOB
If you want a physical joystick to do diagonal jogging, then you need a joystick with 8 contacts (which you could network to 4 PLC inputs, using diodes).
To do it with an 8-position 4-contact joystick, you would probably need some convoluted interface electronics or PLC logic, to ensure that both axis-jogging requests are processed in the same scan of the PLC program. I.e., either both inputs need to close simultaneously +/- 1ms, or the PLC program needs to hold off all joystick jog requests for ca. 100ms, while it waits to see if a second axis jog request is going to arrive to go with it.

Re: OPCON and USB-BOB
Two inputs on at the same time does work just fine, as long as they both close in the same scan of the PLC program.
Since diagonal jogging was added to CNC12, it has been possible to do diagonal jogging with a Centroid jog panel (e.g. pn11077) with no special PLC support. You just have to press both buttons at exactly the same time. This is, of course, hit and miss.

Re: OPCON and USB-BOB
Hi, i just saw this thread and i am wondering, why i did not read earlier about that.
This Bob looks really great. Exactly that what i am looking for. Is there an Information, when it is available? Or do you still need beta tester?
This is my acorn Projekt and i need a lot of Inputs/outputs for hardwired Switches, additional encoder Port for quick control of tailstock, Status LEDs, coolant, etc.
