We have to shut machine off and restart.
Any suggestion would help

Multicam shut down last friday
Restarted Mon. morning, ran for 20 min. and same screen appeared, When I tried to cancel out, this screen now appears

DNC Error deteched
DNC # 2
Err: Modbus Timeout
Slave : 20

if I try to continue, I get the same screen with a different DNC # From 1 -13

Any suggestions on what going on? Thanks

Sounds like your Rio board is having some issues, your rio board is located in the carriage head, at the top of your carriage in the same locations as the belt for the z-axis, look to the rear of where the belt loops around the motor drive pulley, (the rio is a small green circuit board, approx 3x3 in size)two possible remedies:
Make sure the you turn off your machine before you do this,if you do not you will fry the rio board for sure.

1. With the machine off, and you locate the board. You will find a couple of plugs connected to the board, disregard the ribbon cable. Unplug and reconnect the plugs(not the wires)make sure they are seated firmly. Power-up and run your machine, also depending on the age of your machine, Multicam replaced these plugs( bad batch)if they are blk in color, these plugs need to be replaced, if they are orange or green then the plug are fine.

2. It could be your wires between the Rio board and the control board, there could be a break some where in the e-chain.

3. It could be the Rio board itself.

One other thing; make sure that the Rio board does not have a nice warm blanket of dust covering the board, heat kills circuit boards

Hope this helps

My plugs are black and seem loose, and we did have some dust up the top of the circuit bd. machine is a 2006

The black plugs are the defective one, that Multicam replace a few years ago. If you give them a call they should be able to give you a pn# and price for the correct plugs.
