FLSUN V400 E3D Revo Micro (High Flow) + Bondtech LGX Lite extruder conversion

prusaprinters

As I really loved the E3D Revo hotend on my Ender and they recently came with a High Flow version, I decided to make a conversion kit for the V400. I admit, it is not cheap and it does not print much better than a Volcano, but it is very conveniënt, reliable and I can use the same nozzles on both machines. As extruder I used a Bondtech LGX Lite, strong, small and very lightweight. I used the original motor from Flsun. The cooling fan is also stock. For part cooling a 5020 turbo fan is used.Note: The stock effector needs irreversable modification for this mod. Or you can print one.Advantages:Easy swap by hand;No clogging anymore;No flimsy m2 screws;Lightweight;Super fast heating;Easy to clean;Reliable;Excellent customer support;Total weight: 360 gramPlease see attached pdf for simple instructions.Software mods Klipper (printer.cfg):Change E-steps (rotation distance in Klipper, see below for my setting)When Flsun motor is used, the direction should be reversed (see below)Change distance from probe to nozzle (see below).

I use stock Klipper, so I don't know how it works with Flsun modified Klipper.
