Being that this is my first post I would like to say hello to everyone!!!!
This site is invaluable to anyone in the cnc world.
I have an arrow 750 with an a2100 control.
2 months ago the RT board failed.
I ordered a new one ($4700.00), plugged it in and the machine started.
Today the machine gave the same error with the red light on the bridge board indicating that the RT board failed again.
Has anyone had the same issue?
Could the bridge board be taking out the RT?
A while back the power supply fan failed and smoked the supply.
I replaced it and all was well for months.
If anyone has any ideas I would be extremely grateful.
Thanks,
Ed
