Can updating the 7i96s to recognize the 7i77 disable the TB2 connector encoder?

Hello, I have 2 7i96s boards. The first one has the original factory firmware and is used for lab testing. I tested it with THCAD2 on the encoder input and was successful in receiving the frequency and reading it, showing the frequency speed. However, to my surprise, on the client's machine where there is another 7i96s that was updated to work and recognize the 7i77 plus the 7i84, I did not get the same result, it cannot read the frequency. After much analysis, the only thing different in the HAL programming is the configuration sserial_port_0=3000, which is different to enable recognition of the 7i84. Setting encoder-mode to 1 did not help. Why am I not getting the same result? Is there some configuration that I am forgetting to do?

 

You have 1 encoder on Mesa 7i96S and 6 more on Mesa 7i77, so you can use any of those for THCAD.
The issue of it not working might be changed encoder number in hal in the firmware, so use the "show hal configuration" from the "machine" menu to check what number is assigned to Mesa 7i96S encoder, should be 0 or 6.

The 7I96S_7I77 configuration moves the 7I96S encoder to encoder 6 (and aliased encoder 7)
This was done to be compatible with 7I77 configurations that expect the 7I77 encoders
to be encoder numbers 0..5

Note that you need to set num_encoders=8 (or leave the num_encoders
out entirely) to access encoder 6

 

Good morning, ,Mr. Tommy, light thank you for your reply, but the available encodes for 7i96s are:

 

and for 7i77 they are these:

 

What could be the reason why this 7i96s board cannot read the frequency but the 7i96s in the laboratory can read it?

Did you set the number of encoders to 8 in the hal file?
Enc0 and Enc1 are MPG encoders as you have the Mesa 7i77 set to mode 2 or 3, that makes the total number of encoders 9, 1 on 7i96S, 6 on 7i77 and 2 of MPG on 7i77.

Thank you very much Master PCW I performed the following procedure to find the signal:loadrt hm2_eth board_ip="10.10.10.10" config="num_encoders=8 num_pwmgens=1 num_stepgens=5 sserial_port_0=3000"setp hm2_7i96s.0.encoder.00.counter-mode 1setp hm2_7i96s.0.encoder.00.filter 0setp hm2_7i96s.0.encoder.00.scale -1setp hm2_7i96s.0.encoder.01.counter-mode 1setp hm2_7i96s.0.encoder.01.filter 0setp hm2_7i96s.0.encoder.01.scale -1setp hm2_7i96s.0.encoder.02.counter-mode 1setp hm2_7i96s.0.encoder.02.filter 0setp hm2_7i96s.0.encoder.02.scale -1setp hm2_7i96s.0.encoder.03.counter-mode 1setp hm2_7i96s.0.encoder.03.filter 0setp hm2_7i96s.0.encoder.03.scale -1setp hm2_7i96s.0.encoder.04.counter-mode 1setp hm2_7i96s.0.encoder.04.filter 0setp hm2_7i96s.0.encoder.04.scale -1setp hm2_7i96s.0.encoder.05.counter-mode 1setp hm2_7i96s.0.encoder.05.filter 0setp hm2_7i96s.0.encoder.05.scale -1setp hm2_7i96s.0.encoder.06.counter-mode 1setp hm2_7i96s.0.encoder.06.filter 0setp hm2_7i96s.0.encoder.06.scale -1setp hm2_7i96s.0.encoder.07.counter-mode 1setp hm2_7i96s.0.encoder.07.filter 0setp hm2_7i96s.0.encoder.07.scale -1

the result was satisfactory: 

 

the result came out on encoder 6 and 7 of the 7i96s, thank you very much, I will follow the next recommended steps for this to be recognized as Z movement.
