2. The starting point of the printing interface is leaking and cannot be connected.
First confirm whether the print head has been disassembled before, and then
modify the parameters. Before modifying the parameters, confirm whether the
interface leakage is caused by a lot of wire drawing the day before yesterday. If so,
adjust the wire drawing parameters first. , if there is not too much wire drawing
and it also causes interface leakage, you can adjust the software parameters to set
the additional loading amount to be larger or the compensation length to be
larger.
3. If there is no problem after adjusting the previous parameters, but the printing
interface still cannot be connected and leaks occur, and the print head has been
disassembled before, you can check again whether the print head is installed
properly and whether the nozzle is loose or sliding down. Check whether the
Teflon tube under the extrusion is inserted all the way or if the tube is short.
