E3D v6 Robo R2 shroud with new IR board

thingiverse

Goal: Find an IR board for Robo R2, as mine died and Robo had none in stock. I resorted to using a E3Dv6 clone heat sink, which required switching to this shroud. You can still use the old Robo IR board with this setup, as I think I've configured it properly. I prefer the clone heat sink over my original one. The clone uses a 30 mm fan, is more rugged, and allows for easy adjustment to be square with the bed. The shroud's hinge notch is high enough to trim to fit the IR board using one of the three included spacer pairs. A light pipe lets you see the led on the larger IR board from the front when printing with clear filament. I've tested various combinations of clone heat sinks and throats, finding that overall length varied from 63 mm to 64.5 mm when using a 13 mm nozzle. The shroud should accommodate any combination. My previous shroud has instructions for forming the shield at https://www.thingiverse.com/thing:3063864 I've added two hex files: one is the original R2, and the other is modified to match the Chinese 3950 thermistors supplied in E3D clones. I reduced the Z size by 5mm to account for longer hotends and x size by 3mm to accommodate my new gantry bearing holder. Insert the hex file on a USB drive, navigate to it from the LCD, select the desired file, and load it.
