Hello,
I posted last week about a UART problem I am having with my Anilam Crusader 3 Axis Mill.
It worked fine several weeks ago and then last week it would not upload and gave me a UART Fail when I did a loop back test.
I have since replaced the UART chip which was an NEC 8251 chip (UART Chip) and also replaced the Intel 8254 chip (Programmable Interval Timer). I also checked continuity from the DB25 connector the the card connection and all is good.
I still get the error.
Anyone have any idea how to troubleshoot this? Would bad capacitors on the board possible cause this?
Thanks,
Steve
