This is an upgrade kit for stock FBG5 printer.
You need:
1(2)pcs TMC2209 stepper motor driver
2pcs 4010 turbines
Lightweight NEMA17 17HS4023 steppermotor and a little welding.
Use driver for Extruder motor (and Z axis optional). Keep in mind that drivers should be installed according to EN(able) pin! Otherwise you can burn driver and/or board. Also you need to invert axis direction anyhow. Next step is to check and correct current. Motors should not be hot.
 
Petg is fine for all parts exept Nozzles.
Use ABS for Nozzles.
Chain and chain links should be printed 18pcs each
