About this deal
Heat the spray head to 230 degrees Celsius and keep the same temperature to remove the spray head kit; and then remove the heating block and throat separately. Compared to the Prusa Mini and the KP3S, the Ender 2 Pro has a smaller build volume on the X and Y axis. It is recommended to adjust the printing speed to 30%-50% of the normal printing speed by rotating the knob when printing the first layer.
After assembling the printer, check that the printer’s three eccentric nuts are perfectly tightened to allow the X and Y carriages to move smoothly without wiggling back and forth. It’s also worth pointing out that most Capricorn tubing kits come with a few meters of tubing and a PTFE tube cutter. As you might expect from a budget 3D printer made by Creality, we get the same Creality PTFE lined hotend like in other printers like the Ender 3. But if you look at the Z seam in the back of the model, you can see the inconsistency I was mentioning.The bed was only set to 45deg and I did notice that I had the fan from the PSU blowing onto the part.
The filament seemed a bit suspect, so I threw it away and loaded a fresh spool of Matterhackers Build Series Blue PLA.The soft magnetic sticker/carbon-silicon crystal glass is smooth and non-stick, try to apply solid glue evenly on the glass plate/or stick a layer of masking tape before printing. It has stronger anti-interference, faster and more stable motion performance, silent printing, and low decibel operation.
