Oops, I think I did jump this step... Where set I this 'configuratioin.h'? Is it on pronterface? Do you have a link with instructions?

I'm currently calibrating my extruder.

I've told it to print out 100mm but it actually printer 185mm

How do I correct for such a big difference?

What a difference calibrating makes!

It is in merlin FW. Open it in adruino IDK and there you will see configuration.h tab. there search for serial rate.

Can someone recommend me a better hotend? I'm having so many issues with this one such as I spend about 15 minutes trying to get new filament inside the hole, and it clogs and backs out frequently, doesn't feed correct length no matter how many extrusion steps I take, and so on. No a single print is the same... I tried a lot of things for the many months that I had this printer, that I'm now convinced it's the HE that's the problem...

• When I withdraw filament, I just loosen the screws holding the filament against the drive gear, with the extruder up to temperature. Then I pull it out. At the end, the tip of the filament is pointed.
• My filament hole in the extruder and in the hotend don't line up. I find the easiest way to reinsert filament is to keep the pointed end from the step before (I used to trim it off). Now when I insert filament it just guides itself in.
• Make sure that you have a fan for PLA. I tried printing PLA without a fan and it was very tough to get things to work out.
• I have been running my printer for 3 months with spacers instead of springs on the tensioning screws that press the filament against the drive gear (picture later tonight). It has worked very well and very accurately.
• If the print comes out wobbly, try replacing the screws that hold the hotend in place with slightly larger screws (only if the hotend wobbles when you pull on it). Worked wonders for me.
