@Michael Woodward This is a complete new firmware, beyond what Robo offers. They have frozen the R1 series at Marlin version 1.0.0 and this is based on Marlin 1.1.7. There have been a lot of changes and there are many more options enabled in this firmware than in the original Robo firmware. Both @danzca6 and I believe this version of the firmware makes all of the R1 series printers better. It is not endorsed nor comes from Robo. This firmware has been community driven. If all you really want is what you mention in your post and nothing else then consider self modifying the Original Robo firmware.
