AnyCubic I3 Mega (S) Direct Extruder by MaKr78

Last crawled date: 3 years ago

This is more a collection of what parts I used for the direct extruder mod. I mixed parts from different remixes and made a new pcb holder with drag chain mount point. Here is a list of the parts I printed and additional stuff needed for the mod:
Printed parts – Thank’s going to the designers of the parts mentioned below:
carrier plate with Bltouch support and fan duct:https://www.thingiverse.com/thing:4299180
belt tensioner:https://www.thingiverse.com/thing:4361102
pcb-holder with drag chain mount (I combined the pcb-holder from 4299180 with a chain link from 3207171):
At least for the AI3MS you have to cut the middle fin of the upper bearing holder to get the pcb-holder fit in place.

Parts to buy:
You need to replace the heater cartridge and the thermal sensor, because the stock parts have to short wires.

For the connection of the motor you have to find out. The colors on the connector where different than on the stock motor. I tried and found that the colors should match, no matter if they are on a different pin than on the stock motor.
Additional stuff:
6x M3 nuts for the belt tensioner
2x M3x10 screws ISO4762 for mounting the belt tensioner to the carrier plate
4x M3x22 screws ISO4762for the belt tensioning
4x M3x12 screws DIN7380-2 for the cooling fan
1x M4x20 screw ISO4762 for the part cooler
1x M4 nut for the part cooler
I used some of the nuts and screws from the stock hotend housing.
I also bought a glassfiber GT2 6mm belt, to upgrade it since you have to open the belt anyways.
