I believe that is a smart serial communication error.
IIRC that can be cable problems, marginal power supply problems...

But Peter from Mesa or Andy could probably advise better.

i tried another PSU and cable.

also the 7i73 was working i can swithing the I/O`s
now i have to order a new 7i76e i killed by testing but it`s my fault.

Almost always the "DoIt not cleared" error is cause by latency issues on the host PC

To verify this, run the command:

halcmd show param *.tmax

This will show the individual and total ( servo-thread.tmax ) times used by LinuxCNCs real time functions. These times are in CPU clocks, to get an idea of the total clocks time per servo thread period, look at motion.servo.last-period

Also what host PC hardware are you running? If you have a Intel or Qualcom MAC you must make some driver setting adjustments with the ethtool utility

halcmd show param *.tmax need some parameters

Hmm halcmd show param works for me:
