Can you adjust the bed on Taz 6?

This came up during another discussion I had but I'm wondering is it possible to adjust my bed to try to get it more level than it is now? I can tell that it isn't level looking at it and I know other printers have adjustment knobs. It does auto leveling just fine and prints but I can see where it c...

Re: Major PLA curling issues

I'm currently updating cura to the most current version as well as my firmware. Hopefully that will do good things not bad. Have all my configurations ready to reinput them after the update.

Re: Major PLA curling issues

Wet sanding has always been superior to dry sanding. You only need a little water, either dip the sandpaper in water or use a spray bottle to spray on a little water. Of course, do this with the printer off. Dry sanding you may end up with dust on your electronics and axis rods, so.... choose your ...

Re: Major PLA curling issues

Well looking at your picture your Z-offset needs a little adjustment, but if you have been printing CopPoly(NGEN) filaments there is probably a little still left on the bed. PLA does not stick well to it, so you will need to wet sand it lightly with around 2000 grit paper. The wet sanding helps to ...

Re: Major PLA curling issues

Just checked my zoffset.. It is -1.520 Again that is what was set at the factory and u updated my firmware recently so put that and the estep values back in from the paper provided by the lulzbot testers. If you think I need to lower it for better adhesion, I'd there a setting in Cura that allows t...

Re: Major PLA curling issues

Here is a photo of a failed part. I laid it back on the bed for reference. As mentioned, this happens when the part is thing like maybe 8 layers in but because the bed was full of parts, the layers are taking a long time.

Re: Major PLA curling issues

What's your Z-offset? It might be too far away. Mine is set too -1.50. I bottom out at 1.56. Also, It sticks too much, sometimes its hard to get the print off the bed at 60C. I set my bed at 55C. Another thing is if your PEI surface is too smooth, wet sand it with 1500 to 2000 grit sand paper. The ...

Re: Major PLA curling issues

Post a picture of the print bottoms. Why are you printing the first layer at .425 when your layer height is .15? Maybe I'm getting the settings confused, but the first layer is usually a fraction of your layer height to promote adhesion to the bed. Yes.. The initial layer height defaults at .425 an...
