Re: [Emc-users] MESA card suggestions
Hello Alan, You can start with one 7i96s. Then you can add one 7i84. Then you can add 7i74 for 8 pieces 7i84. Or you can start with 7i96s + 7i74 + (2 to 9) * 7i84 imidietaly. I dont like sharing inputs. For control panel you can use input matrix.

The 7i96S is available (unlike the 7i76E, which would be another good choice) but it is a little short of IO, having one input fewer than you require.

But it's asking for trouble if you get stuck on one. Separate positive and negative limits is nice to have, as it allows you to jog off the limits. That said, if you have good homing you should never end up on the limits unless something goes wrong. -- atp "A motorcycle is a bicycle with a pandemonium attachment and is designed for the especial use of mechanical geniuses, daredevils and lunatics." — George Fitch, Atlanta Constitution Newspaper, 1912 ___ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users

I am looking for a suggestion for the best MESA card to be used with an ethernet connection 4axes Teknic servo / stepper taking a step/direction input of 5 to 24V Ideally this would be in a format that I could mount in a simple enclosure. 3digital inputs per axis, so 12inputs 1 additional digital output. I will be using a fresh build of linuxcnc on a 64bit Ubuntu platform. Thanks very much, Alan ___ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users As Andy suggested, a 7I96S is close but shy of one input. If the three inputs per axis include limits, you could save inputs by sharing limit inputs between axis, In addition you can share a limit and home on the same axis. With maximum sharing you could get away with only 5 inputs (4 home switches and a combined limit input) Peter Wallace Mesa Electronics ___ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
