I am a media artist from Germany and I work a lot with technology.
I got a UR5 CB2 a while ago for little money and want to work now with the robot together with a dance company to create a theatre piece.
Unfortunately the motherboard display output fails from time to time thus I cannot work properly with the robot. The official repair would be way to expansive for me.
Thats why I am asking if someone has an old motherboard to sell for me? Especially if it was replaced due to empty BIOS battery.
The board is not useless, BIOS can be restored.
I hope someone can help me out, as the CB2 is not longer supported by the official support.
You can use a CB3 motherboard for CB2. You’ll have to flash a new PolyScope to the USB drive and transfer programs and calibration files from the CF memory card.
Your local distributor should be able to help you.
Did you manage this? I have attempted upgrading our original CB2 motherboard with a fresh CB3.1 motherboard but having a fault C201A1: Setup of safety control board failed when trying to power up/initialise the arm
Yes, I’ve done it many, many times. It sounds like you’re using PolyScope 3.X for your CB2 robot. You will need to flash PolyScope 1.8 to the USB memory.
I did manage to get the old motherboard working again following a “Fix CB2/2.0 - controller that won’t turn on” guide where you replace the 3v battery with a new one and short a couple of pins to get it to boot. It says its a permanent fix but seems once powered down, even with a fresh battery in there is needs the pins shorted and BIOS settings restored
