Hi, I bought a Creality Spider hotend for my Ender Neo, oops apparently its not supposed to fit - well read on.
I followed the instructions and fitted the great looking Red spider hotend, all went as instructed, however after doing an “auto Home” I realized my mistake, the Spider is around 6mm shorter and therefore the fan would hit the bed as the nozzle is too high!
I had a think and then realized if I took a nozzle from my K1 and reduced the nozzle length by 6mm (on a lathe) the height is now correct.
performed a manual and auto bed leveling, z offset etc.
Tried a few prints - not very good, until I increased printing temperature by 10 degrees.
It works great - by the way i did not perform any calibration it works straight from the box…
will try increasing the print speeds next.
I installed my new spider v3 tonight. I found quickly that it was shorter also. I found on printable.com a fan and cr touch mount that I printed on another printer. Fit everything right up. Ender 3 v2 Neo Spider Hotend Adapter Brackets by Retro Hipster | Download free STL model | Printables.com
After that I did a PID calibration and set my E-steps. Adjusted retraction length and speed. Sliced a retraction test model and it was very smooth. Abd ran great. Pleased so far. I will start playing with flow and speeds next.
