Issues with Rostock 301

[mosterkamp]

Thank you in advance for any help. Some issues I am facing and cannot figure out:

1) During testing, the extruder seems to work and flow. When printing, it does not flow well, and comes out of the gaps between the extruder and the heat sinks - it seems to be leaking. I am using the default speeds provided by the config fine.

2) I calibrated, and everything is level. Slight sticking at Z0.00, and moving at Z0.20. When I attempt to print anything (elephant sample), not only does it not print well (#1 above), the motors will jump and start lowering to the board (Z-0.1) and start removing the tape. Not sure why this is happening. It provides the initial layer just fine and occasionally a few slices. Then, it decides to start dropping and tearing apart the tape. It seems like the stepper motor decides to go in reverse on Z sometimes.

Anyone have any ideas on why this could be? Using Repetier/Slic3r software.

Again, thank you.

Hi,
1、The reason why filament come out of the gaps between the extruder and the heat sinks is that the nozzle have been clogged inside.You need to disassemble and clean it or just to replace with a new one.
2、As to the second issue,could you take some video showing the details?
