Since the pi version of LCNC has been thrown under the bus due to the poor reliability of the odroid that was building it, I'll have to either start building LCNC from sources, or change back to something like this to run my Sheldon lathe. If my other business takes off, I should be able to do it with something like this.
The 7i90 with its stack of 7i42's works very well, and gives 72 i/o lines to run the lathe with all on those little green screw terminals, very handy to wire up. The 7i76e doesn't need the 7i42's for noise protection, but the d version I put into the 6040 build doesn't have enough encoders to do what I'm doing with the pi-7i90 combo. I have a pair of the $20 MPJA dials on the front of the apron for x-z jog drive since cranks were removed in the conversion, with variable jog per click set up in my .hal, feeding two of the encoders in the 7i90, but the 7i76e only has one encoder unless I can find a 5i25 file that puts 2 more on the P2 connector, not in used ATM as the 7i76d is handling it all and still has some i/o left. So I'd better checkout the other two cards you mentioned to see if duplicate resources are available. I just did, and the 7i90 is it, no other board or board combo does enough encoders AND stepgens, I'd like to use the 7i76D, but I'd have to see if Peter could assemble a PROB_RFX2 file with 2 more encoders on p2. Or has a daughter card for the 7i76d that would supply the encoders. How many ethernet ports does it have, the pix aren't that explicit, all my machines have at least 100Mbit net connections to the world thru my main router too. It seems rather a kluge to hit the gigabyte switch in the garage just to hit another cable coming back to an e-net mesa card an inch away. If it only has one port, what happens to the connection latency when there is traffic from the other 3 machines out there now if such a hookup involving that 8 port switch was done? And what happens if that switch has to talk to a 100Mb target at the same time. I might have to upgrade all my net stuff to gigabyte. I think the 2 D525MW's have gigabyte ports, but the old Dell running the G0704 might be 100Mb. My net connection is only 10Mb down. None of that appears to be a problem, but we aren't controlling heavy machinery with it either. Thanks Mark, for materiel for future ploting.
