I am new to 3d printing and have a Creality 3 V2 printer. I decided to run a test on a part of the B737 Checklist. As you can see from the attached screenshot, it's not working too well. It seems the base of the excursion is not sticking to the heat plate. I first tried a test using Hatchbox PLA and it drastically failed as it kept clumping the filament when it started to lay the filament, and it would not adhere to the heat plate. I have cleaned the heat plate with 60% rubbing alcohol in case fingerprints were affecting the adhesion.
Anyone have ideas?
The glue stick and the CR Touch has done the trick for me. I always clean the glass plate before I start a 24+ hour build. so far, I printed one part from the motorized throttle small and one from the MTU v7 parts list. All look great.
Feeler gauges to level up and hairspray works for me
Thanks everyone for the advice. I used the glue and started to build part for the Z-axis motor on thingiverse. After I learned to rotate the part in the slicer, the build went well.
I use Loreal Hair Spray (Extra Hold) on my glass bed. You will always get the best results with your own tuning of the profile, every printer is ever so slightly different, despite being exact builds.
Speed is also very important, don't go too fast and you will get much better results (from my own experience).
Thanks everyone for the suggestions. I am going to clean the heat plate as suggested and try the glue stick i ordered off Amazon. It's suppose to arrive today. I did order the CR Touch Kit. Not sure if any have tried it or not..
I have the FDS Dual Seat MIP and Pedestal. My main goal for the 3D print is to build the TQ and sidewall parts. Figured I'd start with something small like the checklist. I'll post my progress in a couple of days.
Welcome Steve to a whole new world in 3D printing.
The comments above are all critically important as the bed MUST BE LEVEL and is as simple as to do as suggested using an A4 piece of paper. Important when doing the levelling is to also do so with both the bed and nozzle heated to operating temperatures as they do expand. I found a great levelling program that I downloaded and use which is excellent.
I now have a CR10 v2 but used to have an Ender 3 Pro and got the glass bed for it. I don't use tape or glue but cant emphasis that the bed MUST be clean with no fingerprints etc on it. The skin will leave an oil residue on the surface and wont stick on it. Prep the bed as suggested above by others remove and wash it with hot water and couple drops of dishwashing liquid that should get rid of any oil on the surface. Wipe it dry with paper towelling and again make sure you do not handle the surface with your fingers Put the plate back into the printer and do a final clean again with paper towelling and some Metholated Spirits and wipe clean. Once dry spray some 100% Rubbing alcohol onto the surface wipe dry with a fresh paper towel. The bed should have a sterile and clean surface. Then run the levelling test and you should be good to go after that.

You might also find a full guide to the Slicer/Print settings in this thread which might also help you https://www.737diysim.com/forum/need-help/cura-settings-1?appSectionParams=%7B%22origin%22%3A%22member_comments_page%22%7D
It shows an issue a member was having trying to get a good print and pics of his effort and subsequent print results after using those setting. I think the pics speak for themselves.
Anyway good luck and there are many on here that will give good advise if you want to find anything out
A good indicator to whether you have the bed leveled to the correct clearance is to check the shape of those first lines that it lays down. It they are round then there is too much gap. They should be more oval in shape (you can feel it) amd if it is a flat smear with not much height then the gap is too small. That test strip it runs down the edge of the print bed to ensure that the filament is flowing well before the print starts makes for a good check.
If the bed is level with the right amount of clearance then there are ways to enhance the adhesion. One popular method is to take the common blue painters tape and cover the print surface with that (one layer thick with no overlaps). It does a good job for helping with adhesion. The only downside of that is the part might tear the tape when removed so it has to be replaced with a new strip.
There is an alternative using a glue stick and applying a light coating. I have used the purple glue stick and it does work well. You need a good scraper like a putty knife to clean and accumulations that build up and a good wipe with an alcohol pad helps. You just need to do a little scraping between prints to ensure the bed is smooth and then reapply a little from time to time if the parts do not stick well enough.
One last suggestion is to slow down the first layer or two. I use 10 mm/sec for the first two layers and it seems to help with getting better adhesion. I know Cura has the options for controlling the speed and number of layers along with a number of other parameters.
Hope that helps.
Looks like your print height is too high. Are you printing with 0.4 nozzle??? I would take the glass bed to the sink was with HOT soapy water, dry with lint free cloth, relevel the bed with a piece of A4 paper so it just drags under the nozzle when you pull it. Do this for all 4 corners at least 3 times. Then do a calibration on the extruder to check that it’s correct (100mm).. Once you have all this done , rerun the same test print you just did. Good luck..
