Tips on getting a really nice first layer? I've got a robo3d printer, and the first layer is always a little rough. I have a heated bed, using pla 70c on the bed 215 on the pla. Using hairspray to make it stick better. First layer always seems to have skips in it and doesnt seem to adhear well. I do skirts around the object which has helped a lot. Right now I'm printing some add ons for the printer itself, so I'm not that concerned, but I'd like to get it fine tuned...

I just found this, and it should help me out a lot, if I can make the adjustments. Mine most closely resembles:

My first layer looks very similar - rest of the print usually is ok, so it seems like a bed leveling issue.

I'm using mattercontrol and it has an auto bed leveling guide where its using a sheet of paper to calibrate the bed/nozzle spacing. I'll see if I can find the actual values.

Its actually in the middle of a print. I made some adjustments - I relevelled the bed again, I also found out that my nozzle is .4 mm, not .5mm. The raft and first layer look the best I've seen, but I wont know till it actually finishes. I also changed the slicer engine from mattercontrols own to cura3d. I really want to do that t-rex skull you linked to earlier, but once I get everything dialed in.

Have you used any of the exotic filaments yet - flexible, wood, etc, and where are you buying them from?
