Hi! This is my first post here and I hope someone will be able to help me.
I bought an old PRT standard with a PC. It was working fine when it was demonstrated. Nothing except the connection to the PC was disconnected for transport.
When starting Shopbot3 I get then message Comm Port Seems OK, but No Connection to Control Box Made (port3).
I am using a USB-Serial converter and it is connected to port3.
I tried wiggling cables, changed serial cable to a brand new one, checked for loose wires and disassembled the E-stop. Nothing seems wrong.
I tried to look at firmware and attempted to do a download, turned off the Control Box for 30sec and then back on. Now the steppers started making sounds, but not moving. The LEDs on the control card randomly flashed as the steppers were engaged. I never received a confirmation that the Firmware had been downloaded and shut it down after an hour of flashing and stepper sounds.
So, although Shopbot3 can't connect there must be some connection.
I am at a loss and not sure what else to try. Can anybody help?
