SM2 Bed Leveling Feedback

I’ve read @Tone, @Dojima , @NilartPax and many users feedback on bed leveling experience on forum and facebook groups. So I decided to make a Google sheet to collect more feedback on this topic and existing solutions, trying to share more insights to the team and hopefully something useful to the community. Please help to share your experience with me, whether you have encountered this issue or not. Need opinions and facts on both sides. Thank you for your support!

Hey Jade, nice idea with this sheet :+1:.

Unfortunately it comes too late for the early adopters of snapmaker.
There was a long time no willing to help us with leveling issue. If you read the old threads you know this fact.

Even i had to pay the replacement platform on my own, so this means my bed level was not bad enough btw the new design replacement platform was also not “level”.

So, now you want experience from the community to help snapmaker build another new machine and overpriced features.

There are many things to make better but snapmaker creates a new machine and lets the original and 2.0 user step by step alone in the dark.

Snapmaker has to earn my trust again.
I am looking forward to see a quickswap feature for low price and firmware anti ringing feature, then i will think again about this sheet.

Hi Jade,
thanks for showing interest! Entered my data in the sheet. My bed is awfully bumpy, and I do 11x11 calibration, which gets it just good enough to have successful prints, but of course 11x11 takes very long. I never investigated the option of getting a new platform, because I only realized very late how bad my print bed actually is and was out of warranty by then. Also, users claim that even the new platform design is no guarantee for having a decent print bed afterwards.
I’m thinking since a while now to get a decent milling bit for aluminium and use the milling head to flatten the platform myself. Was too lazy yet to take the neccessary action, I get along somehow after all.
All the best
Hauke

I find 3D printing much more forgiving than using the CNC. The way the bed is mounted means that the CNC pressing down on the extremities (front and back areas) deflect a LOT. It’s too bad a 4 point mounting system wasn’t implemented instead of just 2 points.

I’ve put in my row. Thanks for collecting this feedback. I hope it can lead to some lasting fix?

I’ve been too scared to even try the CNC, TBH. I don’t want my bed leveling when 3d printing to get any worse.

Sorry to ask, I am quite new to SM, I just tried a few small projects
in some case I found the print head like, scratching the supports and give out some scratching sound, is it possibly the leveling issue?
My last project was printing a dog with legs of about 3 mm diameter, in 10 mm height, I think the printhead crash into one leg and detach form the base. surely ruined my project.
I was still wondering what’s wrong with my setting, and I find this post today, so I ask if I am in the correct thread.
Thank you bro.

@TerryGTB
I think it should be a Material issue.
Are you using SM original Filament? If yes, please buy new one. The SM Filament likes to warp while the print. In the end, the warped edges are so high that your nozzle crashs into your printed part.

If you had bed leveling issues, you were not able to print the first layers.

Get it, I am using SM original filament
It is not a big deal, at least most of the time I can finish the project, just the scratching sound was not pleasant, especially when I was sleeping :slight_smile:
BTW, which filament you will suggest to avoid the warpping? I am open to any suggestion as I am a newbie.

@TerryGTB
I wirte you a PN

Filled in my experience.

And you should really start selling the “new” gantry (especially for us Kick starter ppl with bigger, worse, gantries) and heated bed replacement.
I now have a new gantry that solved most issues (only one area of the bed isn’t flat anymore), but I think I could get it to print better with a new heated bed. Mine is NOT 100% flat. Probably borked from the not flat gantry I had.

The way I fixed my original bed was to put it upside down on a manufactured stone surface (my Kitchen benchtop.) Then at each screw position I placed a layer or 2 or 3 of copper sticky tape to shim it. You can see the light under the posts that need shipping, there are stainless shim washers available but I have not tried them yet.

Something update:


I bet it maybe one of the leveling issue for the first layer.
I have tried auto level a couple of times, but the print head goes below and bend the heating bed at the top right corner position everytime, then it reports something gone wrong and stops leveling. Just pissed me off.
Then I manually level once…and it works, such weird.

I don’t remember ever being offered the new style support platform. It’s something I’d definitely like to try out since I still have to switch to the new linear module as well

Hi @Jade, did this data input yield any results? Would be happy for any update.

Hi @Hauke , I’m sorry to tell you that I did not come up with a solution with the survey data. The sample size is small. Combined with the information that I collected from support tickets and internal testing reports, I found that there are several causes for the bed leveling issues and they require different solutions. The troubleshooting process is quite complicated, which requires a lot of steps and time. The engineering team is still trying to see the possible solution on firmware optimization. But I don’t see any obvious progress in this method. We are also testing a few other solutions while there’s no major progress yet.
I saw that you mentioned in the table that you did not try using the new version of the support platform. There are about half of the users who filled out the survey did not try using the new version of the support platform. And there are about 70% of the users who filled out the survey mentioned that they did not contact the support team to troubleshoot this issue. However, from the support tickets data, it shows that a majority of users have improved the full bed printing results by using the replaced support platform that provided by the support team. I also know that replacing the support platform is not a 100% reliable solution since the bed leveling issue might be caused by other reasons in some cases.
From the collected info, I know that some users have given up hope of solving the bed leveling issue and they refuse to spend time on this problem solving further. There are also some users who still look forward to the day of solving it completely.
I plan to include this topic in a bigger survey that will collect overall feedback by sending an email to all SM 2.0 users. I hope that I can get a list of the affected users. Then I will be able to evaluate the scope of impact, and maybe provide possible solutions/replacement parts to them once these resources are ready.
Last, I appreciate your care on this topic. If you have any suggestions, feel free to send me messages to discuss further. Thank you.

Hi @Jade, thanks for the detailed reply, appreciate it!
Just to understand my options (and since this might be interesting for others I ask in public): How could I get the newer platform, and how much would I need to invest? I did not pursue this option yet because with 11x11 calibration I get along, but admittedly I’d not be averse to avoiding this time consuming process if the invest is acceptable and success is likely.

You need to email support and ask for the new platform, i paid about 39€ plus shipping.

One has to be said, my new platform was only slightly better than my original one.

I’ve just emailed support requesting info on the newer support platform. I have to admit that I’m just now getting back to using my Kickstarter A350 and am running into several issues surrounding bed leveling.

I recently re-read all the threads about leveling issues and about the possible need to adjust the inductive sensor on the 3D printhead.

So I took a look at that procedure and discovered that my sensor indeed had an issue. It was tilted backward slightly when I first took a closer look.

When I attempted to loosen the cap head screw (before removing the side cover) it just made a ratcheting sound and spun. When I removed the cover the picture shows what I found. The plastic surrounding the rosan insert had cracked completely and there was no way I was going to be able to adjust this sensor. I have emailed support about a replacement sensor but have not heard anything. I also ordered and received a new 3D printhead and that leads me to another question.
Do replacement printheads come properly adjusted out of the box?

And how does one adjust this sensor if the cap head screw is behind the mounting plate when the printhead is installed? Or am I not reading this procedure correctly?
