So I was excited to do my first print and ran through calibration to ensure it was correct. once finished, I let cool over night but had issues getting it off. Really was stuck and took me hours to get it off. Where when I did, it damaged the bed. I still have the outline to remove on top of that. Wondering if I did something wrong I need to look out for or not. So first, how do I keep that from happening. Two, how can I get this off. I imagine I may be able to use other side if I can get off PLA. Third, what size of may is this. I measured 255mm. Website says 235x230… can I order a replacement from Amazon or do I need there pad… and if I did, would it be 235x235mm or 10x10 inch. ![IMG_20200613_100801](https://us1.discourse-cdn.com/flex022/uploads/snapmaker/original/2X/7/7d70731910bce80b7a8b08399f1325f9fb43d2f8.jpeg) Test print, fast.

Hey, till there is no print sheet avaliable at the store you need to write to the [support@snapmaker.com](mailto:support@snapmaker.com) for purchasing a new one, if needed. I have no A250, so no dimensions, sry. I think your level of the bed is a bit too tight, recalibrate and offset your calibration sheet a bit more loose. Maybe it helps to heat the bed a bit to get off your part. Hope this helps! ---

I had something similar happen with my first print. Thankfully it didn’t damage the build plate. I still haven’t quiet worked out why it happened. Since my build plate wasn’t damaged I was able to heat the build plate again and use the putty knife to remove the left over PLA. ---

I use a razor blade scraper like this one: IVY Classic 11156 Razor Blade Scraper with 5 Blades, USA, 1 Pack [https://www.amazon.com/dp/B0051XQDXO](https://www.amazon.com/dp/B0051XQDXO) You have to be careful because you can cut into the bed. Light, gentile back and forth motions with the scraper at a very shallow angle. ---

Thanks for the replies. Luckily the plate is fine just the sheet. Where I have actually built around it just fine. I still cannot get off the remainder of pla on plate even with a Razer. I did manage to get off a little where it does not appear to have damaged the sheet at that spot (the border pla). I was talking with microcenter when looking to get some kind of replacement plate for now. Where they believe the heating plate was to much. I did notice that this set it at 80c for that, where it may have melted into the sheet pretty good. My last build I did I let it run at it’s 70c it wanted at first but took it down to 60 about 10 to 15 minutes later after it finished first pass. I was able to get that off just fine. I also rubbed the surface down with rubbing alcohol prior. So. Would have been a number of things… appears I may still need a replacement from them due to design and dimensions are weird. A 10x10 is to small on side and to large on the other. (9.6 x 10.25 ) is what I measure… Now I am thinking I can use this heating mat on the snapmaker one to protect that possibly. Or if I can get the rest of pla off. I might be able to flip it safely and use that side. ---

When you do the calibration, do not make it too close. You can send an email to [support@snapmaker.com](mailto:support@snapmaker.com) to purchase the printing sheet and ask them about the size of the printing sheet. ---

I first printed this weekend and had same problem. I did calibration step by step as in Guidebook and it wouldn’t come free from bed. On third print I redid calibration, and then moved nozzle 0.2mm up so it’s not so close to bed. It still stucks a lot, but its possible to get it free.
