Okay so here is my current situation... I can print these spikes out but only at a very low temperature. I start it off at 185c for the first layer, and then have it go down each layer by 5c until it reaches 155c. That is the only way I can achieve that print without really bad stringing. However, I attempted to print out a figurine (It is a Dungeons & Dragons figurine of a goblin), and it failed badly. The arm it was printing stuck to the nozzle and failed to print out at all. So I assume this is due to the extremely low temperature. I have a feeling that something is wrong with the temperature sensor, so I am going to purchase an infrared laser thermometer (Hopefully today) and see if I can get a reading of what the actual temperature is.
Also, I attempted to do an extruder calibration. I marked the filament at the base of the extruder and measured out 150mm and marked it there. I sent a command to extrude 100mm of filament at 30 mm/s, and after measuring, it extruded about 96.5mm. So it is underextruding a bit? From what I have been reading, I need to change the extruder steps per mm, but I have no idea how to do that. Would anybody know how I would go about that?
As for the optimal temperature, I will be trying that and will get back to you once I figure that out, as well as measurements from the thermometer. I really appreciate all the help you guys have been giving me. Some people also recommend I do the whole 20mm cube measurement and change the offsets until it measures exactly 20mm with a caliper. Is this a good idea? I wont lie, this has become somewhat frustrating, but I won't give up until I figure all of this out.
