Blue PLA does not stick to base plate: "spaghetti" on extruder

Recommended Posts

Hi to all,

I am looking for help to solve a problem with PLA not sticking to the base plate. Instead, the extruder head pulls the material loose and a big "Spaghetti" ball is being formed on the extruder head.

The problem started after having placed a new reel of blue PLA material (1616)
Before we used a reel of gray PLA material (supplied with the machine) without any problems.

Already we have done the following steps without improvement:
* factory reset
* cleaning the nozzle
* checking the temperature (nozzle 210, base plate 60)
* adding a layer of glue to the base plate

No solutions up till now.

What to do next?

Thanks in advance for suggestions
Regards,
Silvio Rademaker

Hi MechDesigner,

 

Thanks for tape tip. I will certainly try it out.

 

Today I got a print running with increased tip temperature (from 210 to 230). Also I have cleaned the base plate thoroughly. Seems that the glue trick doesnt work for us.

 

We have the printer on a school so I suspect that the heavy use leaves a residue that hampers the sticking.

 

Instead of cleaning with windowfluid (scary combination with electronis) I think the tape is a clever solution. I might even try to lower the temperature.
