Printer "leaks" a little bit of filament before each print

by Hollandator

Hello, I own a monoprice maker select v2 (same as wanhao duplicator i3) and before every single print job run, the extruder pushes out like 4-5 mm of filament on its way towards the starting point of each print job. Does anybody else have this problem, and does anybody have a solution to it?
All help appreciated. thx

Continuous Blockage

by stepea

Having major problems unloading filament - it's getting stuck in the guide tube and the only way to remove it, is to cut the filament then push down the remaining filament by poking the wire down the hole to force it through the nozzle. I'm having to do this each time.

I have had to recently replaced heater cartridge, thermistor, hot end block mount, upper bar mount & guided tube. Not sure what else I can do.
