Original Roland GR-640 / GR-540 / GR-420 Main Board CG1107 – 6000003126

The Roland main board 6000003126 (ASSY,MAIN BOARD CG1107) is the central control board of the CAMM-1 GR series wide-format cutting plotters. It fits the GR-640, GR-540 and GR-420 and replaces the board fitted at the factory. This is a genuine, original Roland part – not a copy or compatible replacement.

The main board receives cutting data from your computer, controls the feed and scan motor circuits and runs the operation panel. When it fails, the usual signs are a cutter that will not power on or freezes on the start-up screen, USB or network communication errors, random resets in the middle of a job, or motors that no longer respond. If the power supply and cables have already been checked and the fault remains, the main board is normally the next part to replace.
