Original HIWIN runner block, type CGH20HA, for the linear guides of the wallPen. It carries the moving unit on the rail.
Replace it when the block develops play or no longer runs smoothly – both show up in the print as blurred edges. A worn rail wiper is the usual cause, so it is worth replacing that at the same time.
- Type: CGH20HA
