First layer issues
January 06, 2015 07:27PM
Odd issue that ive been having.
After 2-3 layers its perfectly fine so im assuming its something with my printer.

The first picture shows the 1st layer with auto bed level on, on the left. Normal Z home is on the right.


Second is a "light through" shot showing that when the print starts its spaced so far I have gaps, then in the center its perfect and on the end of the first layer its all bunched up!


I hope someone has seen this before and can help.
Using 3mm ABS at 230c and bed at 110c

This looks like your bed is not level. The side that is bunched up is too low and the other is too high and you get spaces.

Thats what I thought. I was a bit disapointed that the ABL was off more than eyeballing the flatness.

I just went over it again manually with a sheet of paper...Im warming up for a test print now on a 100mm circle.

Not good again...
Starts out spaced out then gets good spacing and ends with it bunched up.
I checked the level after homing in about 9 places on the bed before starting this print. The nozzle is .1mm from the bed after home.
Also note that the cube was in Slic3r and the disk was in Cura. Both pieces of software are the latest version.
