I just replaced the extruder hotend with a brass nut so it doesn't drag on the second extruder if not perfectly leveled. For my use I don't really need to print with two different heads/colors. Also the roller spools are kinda garbage at first I tried to just print a riser and a spool coupler to accommodate the bigger spool size. But the armature itself is just too weak and bends towards the underside of the bed. So I replaced them with a simple aluminum one and used M5 threaded inserts solder melted into the existing holes and an additional hole I drilled so now it will support a larger filament roll. I also modified the print bed leveling with a nut screwed against the bed with enough clearance left on the bolt to still adjust the bed. The top nut provides greater stability from the bolt to the bed. Otherwise it's an excellent machine easy to setup and go that prints well for the price.

@flashforgesupport4043 Where can someone get that leveling jig shown at 6:58? It says nothing about it in the video description.
