Geeetech

I have problem with making filament clog in hotend. What troath is on geeetech a10? I assemble the hotend im this step. I insert the nozzle to the end, then make half turn back, insert the troath with radiator, make 200 C and turn nozzle max. But when i start. Printing on few minutes i get extruder to tick and when i disassemble hotend i see not meltedv filament down in troath near nozzle. I think the ptfe tube goes to end od troath and is cut correct

I'm sorry I didn't understand what you mean, is it that the hot end can't be heated? Can videos or pictures be provided?
