Gene: Send me your USPS address and I'll mail you a free glue stick that's 99.44% coronavirus free. :-)
Or buy a glue stick on Amazon. https://www.amazon.com/Elmers-Strength-Washable-1-4-Ounces-E590/dp/B008M56Z0O Coronavirus not withstanding, it's seldom worth me making a 15 minute trip to buy something like this when I can buy it online in a minute and it's at my door a day or two later. Can't wait for Amazon Prime drone delivery in 20 minutes. Use a nylon bristle brush to distribute the tiny bit of glue stick and water on the glass plate, immediately before printing. I think the scrubbing of fresh glue and water results in a high surface energy that's needed for a good bond. The white glue experiments I tried resulted in something analogous to a slick non-stick surface. I was surprised by that. It may have been the result of the 110C bed temperature I was using for ABS. I didn't try it with PLA or TPU. It failed with ABS and that's all I needed to know. The glue stick and water works very well for ABS, PLA and TPU. I hope you enjoy glass & glue stick 3D printing as much as I do. The trick is to get good adhesion to a hot bed and good release from a cold bed so there are no failed prints and no need to hack and pry the part off the build plate that results in a loss of bed level that causes subsequent prints to fail and possible damage to the printer... or at least damage and degradation to a plastic build surface. 3D printing requires some patience because it's slow, but it shouldn't require much labor and the process should be repeatable and reliable. That's definitely an attainable goal, because I'm doing it. Others have already done a lot of 3D printing process development. It's inefficient and frustrating to ignore the work of others and repeat the painstaking development yourself. At this point, most people buy a cheap 3D printer from a known good source (Sainsmart should have been good to go), watch a few YouTube videos, and have reasonable success out of the starting gate. It's been painful for me to see you struggling with this.
