Good afternoon community! Being quiet new to FDM printing I hope to solve my problem with your help. The ACE is my first FDM printer. I am (was) quiet impressed by the machine, as long as I printed smaller objects. Two days ago I started a large size project and it failed in the center of the bed. Absolutely no bed adhesion. My bed leveling was in a range of 0.26mm after the initial setup with heated bed. What is strange in my eyes that the printer does a bed leveling prior every print with cold bed and my mesh is turning into a valley in the center. Is there a way to disable the bed leveling before printing? Simon ---

Filament ist JAYO PLA standard grey. Bed temperature is 60°C. Extruder temperature is 235°C for the first layer all other layers 210°C. First layer speed is 30mm/s, first layer infill 30mm/s. Other layer speeds 120mm/s. The strange issue ist that the initial leveling with hot bed was very good but every pre-printing mesh is so bad. ---

Can you post a picture of your mesh? I had very similar issues until I manually leveled the bed. ---

I heat the print bed to 40°C before printing begins. The printer then levels itself with the preheated print bed. ---

That is my mesh @ room temperature (21°C) Bed and extruder not heated ---

Well that explains your issue. See how I manually adjusted by bed [here](https://forum.sovol3d.com/t/warped-bed-question/6637/16). I’ve been printing large objects since then with perfect first layers consistently. ---

That is with bed at 60°C and extruder at 210°C. ---

Indeed, since you’re going to print on a heated bed, and heating the bed changes its shape, Sovol themselves recommends [changing your slicer’s start G-code to heat the bed before generating the mesh](https://wiki.sovol3d.com/en/SV06ACE#v170). Rather than skipping the bed mesh generation (which is useful to redo for each print since the mesh changes a bit each time you remove and replace the build sheet), just have the slicer do the pre-heat _first_. 🙂 The latest profiles in the OrcaSlicer Github have this change incorporated, BTW, so if you grab those, you should get the heated mesh “for free”. ---

I just manually preheated the bed, started then the large size project that failed before and … no issue! Obico is watching the progress and all is fine. Manual bed leveling will follow anyway. Many, many thanks to all of you for showing me the right way! ---

The advantage of changing the start G-code is that, after, the pre-heating will be done automatically with each print without any manipulation. ---

Also you do not need to worry about getting distracted and waiting too long so the idle timeout kicks in and the heater turns off. (Ask me how I know, lol.) ---

Hello again. Many thanks to the community again, especially Minaskar for the tutorial how to level the bed manually. It is definitely worth to fine adjust the bed i.a.w. the tutorial. Here my bed mesh after manual leveling. It takes a while but I can absolutely recommend doing that. ![Mesh after_040908](https://canada1.discourse-cdn.com/flex030/uploads/sovolforum/original/2X/5/5a9de18c5d9dd10eb36a7410b1bf011596842728.png)
