Many thanks for feeding back this.
I am sure this wont be an isolated issue and others will benefit from your follow up reply.
Strange there was no mention of the C controller (which you say you have success with).
I know there are several versions of KRCC and K-IDE (I assume) will be using the latest version which as they say may not support D controller firmware.......still vexes me a little as to why you have success with C controller though.....
Still good to know............
My pleasure
At this point, I'm not absolutely certain that it actually was a C controller. What I can tell you is that the controller didn't even have an Ethernet port to connect to, so I used the COM port instead. That's why I just made a guess.
The only thing I did to that robot was uploading a backup.
According to such backup, the firmware version is AS_01G0031S.
