I’m new to 3D printing. I’ve dedicated many hours of reading and, as a result, have a good understanding of printer anatomy, associated terminology and slicer settings.
My TAZ 6 worked well right out of the box. I’ve got a couple hundred hours on it with no problems. Recently I started having first layer issues. Before going nuts changing parameters in the printer, slicer, etc., I figured I’d better calibrate everything and proceed from there.
So, I’ve been following this write-up:
I’ve completed steps 1-4.
During the printing portions of the steps in the write-up and during most all of my prints with this printer I notice that there is a long delay between when the tool head begins following the print path and when plastic starts to extrude. In a few rare cases filament never began to extrude so I cancelled those prints within the first minute or so. This isn’t so much an issue when printing a large skirt or brim as the hotend will eventually prime itself and begin to extrude. But, on smaller prints such as the temperature calibration towers in step 5 of the write-up, the issue becomes more pronounced since filament is not being extruded once the actual model begins to be printed.
Is it possible this issue is related to excessive retraction during the beginning of the bed calibration sequence, possibly adding to the time it takes to pull filament back into the hotend and, subsequently, delaying extrusion?
Would love to get some input on this.
