I got my R1+Plus last January and have been following this forum regularly with great interest. I have made some hardware mods but mainly focus on the Marlin Firmware Upgrade 1.1.0 RCBugFix (Post RC7) (For R1 & R1+PLUS) thread. I tend to print objects that are challenging and then bring it work, needling my colleague to do the same on his non-Robo3d printer. Good times!!!!
