The top of the pipe has to insulate from high temperature for assembly with other parts. I tried several insulation materials, but it was not very effective. Then I decided to cool that part by using the fan. It it was very effective, but it took longer time to heat the hotend. But this can not be helped.




【What I will have to do】

• I will assembly this parts with other parts. Before that, I should make the other parts...
• I have to connect the temperature control unit with display unit and stepper motor unit in network and communication week. Befor that, I have to make stepper controll unit.
• I need a sleep and rest...

It is still a long way to completion....
