ABS printer bed glass is different

Hi all,

I received my April tier printer last Tuesday. Finally got a chance to get it hooked up and try some prints over the weekend. Successful in getting it hooked up and moving, but not successful with prints sticking yet.

I noticed that my glass bed is very different than what is shown on the website and different than that shown in this Robo 3D video Installing Boroscilicate Glass (sic) from only a month ago. My borosilicate glass appears to be the ONLY bed, and the heating element is directly attached to the glass. The glass bed does not have the printed clips that the video shows, and is not quickly removable.

I've had a Solidoodle 2 since December 1012, but that printer has a heated bed with a Kapton tape surface. Very easy to get prints to stick. Sometimes it is not so easy to remove the prints.

I've not had a glass bed before, but the consensus over on the Solidoodle forums seems to be that removable glass and cheap hairspray is the goto method. I still haven't tried using the blue painters tape yet. It would be great if the Robo boys would make a video showing how to get prints to stick to this new style of glass bed.

tesseract,

Thanks for the quick reply!

OK, so no blue tape (wonder why the Robo boys showed it in their video?). Couple of quick questions:

1. What temp are you using with the hairspray? 100C?

2. Brand of hairspray? Lots of people say some brands work better than others.

3. This is the biggy: How do I keep the hairspray from going where I don't want it to go?

For the ABS guys and this new bed, the Robo guys will save themselves a lot of tech questions and new owner frustration if they make an updated video for ABS printing... Just saying.

Thanks!

For PLA, been experimenting 50C bed temp using Aquanet Extra Super Hold I found at Walgreens .

The addition of bed temp seems to activate the hairspray giving it extra good stick. ABS 100C initial bed temp. Sticks like glue. Put down three rings around the part using the options in Slic3r for the first layer. It is useful to measure the thickness of this first layer after the print completes to help with Z height adjustment. See my post on Z-math.

 

To Stop the hair spray from getting on every thing I drape a paper towel in front of the extruder and move the bed all the way to the front.
The paper towel is wide enough to caught most of it.

 

Out of curiosity, why not? I had some problems with the prints not sticking even with the correct Z-axis height (flat first layer), so I put some blue tape on the print bed. The print stuck much better to the tape, though it still had issues with warping and popping off.

 

I'm at the point where I'm going to try hairspray. Something I never mentioned but I think must be pertenent is my first prints tests were successful using the small amount of blue filament (PLA) that came with the printer. All my issues have started when I ran out and went to a new roll of white PLA from Robo. I used blue tape with the blue filament. The white doesn't stick at all on the tape. I got what I think is a real good first layer, it is flat but doesn't stick at all, it just drags behind the extruder. I tried some hairspray that was laying around the house on the tape and that didn't work, pulled off the tape and sprayed directly on the glass and still no stick. I'm going to get some Aqua net and give it a shot tonight. Any reason why I should expect better results?
