ANET AM8 Notes

Assembly notes (both A8 & AM8)

  • Reverse cross brace on heat bed H frame as this flatterns the belt path
  • The extruder fan can is only fixed by the 2 M3x45 Cap Head Socket screws, so add 2 M3 screws through the fan guard and fan into the heatsink fins
  • The heat break needs to be firmly abutting the nozzle, so loosen the nozzle, and get the heat break in just far enough that the nozzle butts up against it and the block, takes a few goes to get it right
