I've purchased and assembled a MakerFarm 8" Prusa i3v printer. I'm now trying to set up a first print, but when I run it, the printer won't extrude enough material to even lay down. I can't retract the idler and insert the filament because it won't catch on the hobbed bolt when I use pronterface to try and extrude filament. I can only get filament to feed into the hot end and extrude by removing the extruder from the X carriage, removing the spring-tensioned bolts from the idler, and threading the filament through the hole and reassembling the whole extruder. Then, I can finally get it to extrude some material, but it won't extrude fast enough to print. After manual extruding 25mm (which is pulling in more like 15mm or less), it will stop pulling and the filament won't move. I've marked the filament to test this.
I'm using a 0.35mm J Head hotend, which seems to be a mistake being that this is my first printer. It seems like that nozzle is suited for more advanced users being that the nozzle diameter is smaller. The whole filament issue is really annoying and kind of disappointing being that the build guide includes a video where Colin at MakerFarm simply threads it in and starts printing.
Any help would be great! I'd be happy to include images or video of just about anything you need.
