Are you using Sprinter or Marlin firmware just out of interest? Chris |
| Monkey with a mill:
I am using sprinter. |
| raynerd:
Yes, same here. I gave Marlin a go but couldn`t get it running configured despite all the people using it. |

All the electronics are working great but now I am having an unusual problem. As the extruder runs, the nozzle is slowly pushed out. I am wondering if any one has any advise on the best way to stop this. The hot end is my take based on other peoples designs. The standoff/ thermal shield is 1 piece of round teflon with a 1.75 mm hole drilled through. The heater block is threaded to the outside, and the nozzle is threaded inside the teflon, with a washer used to transfer heat from the block to the nozzle. It works great as far as the heat transfer is concerned, and the threading on either side of the teflon was meant to put pressure on it to keep it from slipping, but somehow I need to lock the nozzle in place. |

I found a way to stop the nozzle from rotating out. By drilling a hole perpendicular in the heater block and through the teflon, then tapping the hole, I was able to use an 8/32 socket headed bolt as a friction hold. Here are some pictures, sorry for the quality, I took them with my phone. It is holding well. The problem now is that the plastic that is being printed is not sticking to the platform, but rather balling up and sticking to the side of the nozzle. Any suggestions on how to solve this ? |
