Here is about 0.5G of plastic that needs to be used up Print time takes just 3 minutes, but a working printer is required Need some filament and it works great with 20% infill speed, plus fast honeycomb structure This thing measures 10x10x5mm in size, with a hollow center and dimensions of 6x6x3mm When it comes to adhesion tests, use the Z axis - try adding one at each corner of the bed Please remember that kapton tape and hairspray won't do any good if your nozzle is too high from the bed; this test helps you determine if everything is okay - Here's how to use this: First of all, make sure the nozzle is just about touching the bed (you can use a piece of paper underneath it for that) If the paper slips or moves at all when nudged - that's perfect - then MAKE SURE ALL THE CORNERS ARE LEVEL! And make sure there is something flat on top (like a glass or metal, and a PCB will NOT do) -Add one in each corner of the bed -print with layer heights set to 0.2, nozzle size of 0.4mm Adjust your printer settings accordingly based on the results WHEN ADHESION WAS TOO EASY - WHEN THE OBJECT DIDN'T STICK TO THE BED If this is what happens, you need to adjust the Z endstop so that it's lower by half a millimeter - take another look at the paper you used in step 1! When plastic doesn't come out of the extruder - it stays inside: Move the Z axis up, heat it and let some filament come out -You may need to damage your extruder - just use about one centimeter of that The "origin offset" probably got messed up; find its value in your slicer's settings Adjust your layer heights for this print setting, then WHEN PLASTIC IS TROUBLESHOOTING: DOESN'T COME OUT PROPERLY OF THE EXTRUDER Just add a 0.2mm increase to the beginning height of each object and continue from there, adding increments until you have good adhesion You might want to consider what will happen when plastic sticks too much - that can cause problems removing the thing from the bed altogether Temperature testing will tell us if things are right -If temperatures were set way off either too high or low layers would be all uneven Change your temperature settings 5ºC at a time for maximum effect AND don't forget this one fact - if you really want to have awesome prints quality, remember the fan needs cooling those hot wires so turn it on right after you're done. I do the same by placing it in between each part and getting wonderful results that were always just out of my range before but that doesn't seem true now Printer details Printer brand - Reprap - The specific printer model we are using here is Graberi3
