7i97T+7i74+7i84+7i73

Hi guys
I'm a beginner with Mesa electronic boards and I'm retrofitting a Realmeca T200 cnc lathe ( analogs drivers ).
The configuration I'm implementing is 7i97T+ 7i74+ 7i84+ 7i73 with the bin file 7i97T&7i74d
I have a PWM version error, and I need to find the latest version of the bin file 7i97T&7i74d
Can anyone help me?
Thanks
 

Moved to "driver boards".

While waiting, you can use 7i84 OR 7i73 with 7i97T for testing or anything, without the 7i74, meaning only one at a time.

Here is a PWM version 1 of 7i97t_7i74d.bin




(Version 0 PWM will work but lacks the dither option)

thank you PCW I'll try it out

with this firware which version of linuxcnc works. does it work on raspberry PI?
Estou a usar linuxcnc 2.9.1 e Raspberry Pi 4 8g

The firmware doesn't care about the host CPU
2.9.1 is pretty old (about 1.5 years)

Not sure if 2.9.1 supports PWM dither (V1 PWMgen)
as dither was added in Oct 2023 and 2.9.1 was released
in Nov 2023.

Options:

Update LinuxCNC to current (2.9.4) or use the firmware with V0 PWMgen

 

hi guys i managed to get the communication between Rp1 7i97t+7i744+7i84+7i73 working
Thank you for your help.

My test bench
I know it's nothing to you experts, but for me it's a big step.

Hi guys
I want to connect two MPGs to the encoder inputs of the 7i73
My MPG has A+A-B+B- OV5V e and use two analogue inputs.
To do this, I'll have to use mode 1 on the 7i73 board
Has anyone configured this board in encoder+analogue mode?
Thanks
