Solved it myself, had to set sserial_port_0=00xxxxxx

Hello, can I connect both 7i83 and 7i84U to Mesa 7i95t? I need analog output for the spindle and 7i84U for IO expansion. If I connect them both, only the card in the first port gets recognized.

If we are speaking about communication delays, we also have to speak about communication delay between PC and camera.

After all, what is the speed requirement of the belt after all? Is it 0.1m/s? Is it 1m/s?

I use Mesa myself, and my motivation was not to spend hundreds of hours just to save 50 bucks on Mesa.
Mesa is the only turnkey solution here from what I can see that does not require JTAG programmer to start . I wanted to see what options would I have if for some reason Mesa will not be available in some future. I would hate to see it happen, but boy haven't we seen enough world craziness lately.

I admire all the people dedicating their personal time for the common benefit here. 

>>I think the real question is, why arent i mining crypto when my machine has downtime? make the mesa fallback to a crypot miner

how do you know Peter is not doing this secretly while we sleep? 


 

Thanks for your input Langdons.

I used shielded on the encoder feed and analog control lead. The IO's I left unshielded. These looms are wired up and ready to go.

Little bit of progress. Got the control panel assembled with touchscreen and computer. It's definitely not a small screen....
The DB37 breakout units arrived, which will allow me to use the existing Heidenhain control cables to feed the relay board from the Mesa cards.

I just wanted to check VFD speed control wiring. The Delta data sheet only shows external speed control using a potentiometer. Can I wire it like below, using the axis 4 or 5 on the 7i97t to control it?

I'll activate the FWD/STOP, REV/STOP and OUTPUT SHUTDOWN via outputs on the 7i97t.

Thanks!

The nice thing about linuxcnc is you can call a python program from gcode, have it do whatever you want.... Options are endless really..... Then take that data and keep going.

Ask chatgpt how to do it, it's not that bad takes a bit to setup the m codes, O codes, and python program but is very doable especially with AI now a days

I have the basics built but not completed yet.
