I have set up the start script to prime and nozzel right on the edge of the bed, so to not have to run a skirt to prime...
It has proven to work well, but randomly... The extruder motor turns the wrong way... Instead of pushing... It will pull for the whole duration. Of the prime process when it lays down filiment into the bed....
Meaning for 2 good prints then, it will reverse... Then good... Then.... Good and good.... Then reverse.... Etc... Very Unpredictable.... But you notice it right away..
The only way out is to, release the spring on extruder and push by hand.... Which can lead to a blob start point on your print... As you are regulating flow by your hand pressure as you manually push..
Once the start script is finished the ext will work as normal to print... Which doesn't work as the filiment is already pulled out!
It is random... I can't seems to find out what is causing this? Any insight?
I will post the script shortly.
