New ethercat / probe basic control for minimonster

I have had to set some register in the drive to make it use Modbus.
Could be permission problem, almost anything.
Load the modbus driver only using halrun and diagnoze from there.
Something like this  forum.linuxcnc.org/24-hal-components/310...-speed-control#75848
but for your Modbus drive, not the huanyang.

i'm not in linuxcnc yet. i'm testing it on windows. Drive settings are right. Its not receiving any data back of any kind. Feels like a cable thing. hmmm

so its not talking to my delta vfd either... so im guessing its not the vfd side thats the issue. hmm

maybe  www.com-port-monitoring.com/ or similar?

Hmmm. that's helpful thanks. its doing... something in both directions. so maybe the issue is the spindle talker 2 software.

Any advise on another way to check functions?

So, its definitely doing something different when the drive is on vs off. So that's a start. It does show exception 1 a fair bit.
