Problem with small objekts on bed plate ...

[arnaas1 0]

Small objects (ø8) are loosen from bed plate during start of print. Have tryed lowering bed temp to 0, 30,40 and 60 C. With and without glue. Nozzle temp 210, 215 and 220 C. PLA AND Um2. Any tips?

Hi and welcome to the forum

For PLA put the plate to 60°c with a little glue applied with a slightly wet cloth. (Not too much).

If it gets detached then you might need to relevel a bit closely

How does your first layer look? squished or not so much?

First layer and up to 1mm looks perfect.

About 1mm it goes off the bed plate.

In Cura add a large brim (20lines) you find that setting in the first tab in adhesion type. It will help a lot.

The first layer needs to be very nice to make it stick well.

Based on other posts I found in this forum, I switched from glue stick to using http://www.amazon.com/Aqua-Net-Unscented-Aerosol-Spray-11/dp/B002K33AFM/ref=sr_1_1?ie=UTF8&qid=1420937948&sr=8-1&keywords=aquanet+hairspray+unscented for PLA, along with 60c heated bed. It's the purple-ish can. I spray onto a paper towel and wipe across the glass just so it looks wet. I haven't had any problem with PLA sticking since using it. Never spray the can directly onto the glass while inside the build area! Don't want hairspray getting over any moving parts.

After running out of the supplied glue stick from Ultimaker, I found a few posts suggesting that http://www.amazon.com/gp/product/B000U6FJQE/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1 works great for ABS and I agree, it does. However, I also built an acrylic cover and front door for my build area, creating a heated chamber. That also helps in printing warp-free ABS.

Make sure your first layer goes down with the plastic slightly flattened and not simply laying on top of the glass. If it's not flattened slightly, go through the leveling process again. You don't want to print too fast either. There is a setting for the first layer speed. I typically set this to 20mm per second.
