I have been playing around with the bed for a while and I still can't get the first layer to stick properly. I think I am getting the bed leveled good, I use the paper method. But yet I find myself with the filament lifting off and getting pulled away with the nozzle or some balling in rare situations.

I use masking tape, which I found for $3 at Dollar general. I heard something about shine being a factor, but why is that important? And is more expensive masking tape worth it? I don't want to buy it because I would hate for it to tear when I take off a print.

I also use some glue stick, which seems to sometimes not help, almost like it doesn't allow the filament to stick. I don't think I was adding too much, maybe I was. But is glue stick needed? Does it really make that much of a difference?

So other than that I don't know what to try. I can't get the first layer to work properly. Maybe it is my speed, what is a good speed to print at for the first layer, I am doing 60 mm/s, just like the rest of my print.

Any advice from there with first layers would be great. I am tired of wasting time and filament over failed first layers. But when I do get the first layer done, the second+ layers all work fine, no issues.

Here are the specs of my printer, that should be helpful for people:

  • Printer --> Anet A6
  • Print area --> 220 x 220 mm
  • Heated bed? --> Yes
  • Bed temp --> 50°C
  • I use masking tape on bed
  • nozzle dia. --> 0.4mm
  • Nozzle temp --> 210°C
  • Print speed --> 60 mm
  • Material of choice --> PLA
  • Fan is on after 3 layers

I think that covers everything, Let me know if I need to add anything else.

Masking tape (and blue painter's tape) is coated with a wax-based release agent in order to prevent the tape sticking to itself on the roll. This release agent must be removed with an organic solvent in order to obtain good adhesion. Isopropyl (rubbing) alcohol is good for this. Acetone will also work, but it is a much stronger solvent (which is not necessarily a good thing).

For blue painter's tape, rub freshly applied tape with solvent until the blue dye starts coming off. Then give it a quick wipe between prints to remove any fingerprints, etc.
