not meant for purchase here but part of the patronage ---- Sept 25th update: added REVO version ----- Step included Smart Orbiter v3 Beacon probe (standard) (only tested Rev H, but I think Rev D should work too) or Cartographer Probe offset: X 0mm, Y +18mm requires a top mounted linear rail MGH12H (300mm on ender3, about 400 on ender3max) Requires heat inserts: M3x4mm long, either 4.6 or 5mm outer diameter Needed screws are mostly M3x6 and M3x8 (maybe M3x12) with a couple M3x20 MGN12H top mounted might work with stock endstop, but just in case included an X motor cover No print support needed!! (except for the optional fan noise reducer) On top of the linear rail mount are two optional m3 heat inserts holes 20mm apart and zip tie holes for any type of cable management.
