Marlin 2.0.8.2 for Robo 3D R1

Download Marlin Firmware. Reset settings with M502 and M500 after flashing with new firmware.

Setup

This is for a Robo 3D R1 with the following mods:

• Garolite Surface
• 300mm Y-Axis Linear Rods
• RepRap Smart Controller
• OctoPrint

Notes

1. Glass bed had a small chip so the garolite sheet was a quick and easy fix.
2. 300mm rods were a little shorter than the stock rods so we had to move 2 bed magnets to accomodate. Y_BED_SIZE was reduced to 200 for this reason.
3. Some Robo R1 (non +) models use a different Z lead screw. STEPS/UNIT for this model is 800 and not 2560.
