Hi, I just got my A350 and assembled it. When doing the initial calibration the laser module just smashes into the work surface repeatedly.
I have tried it a few times and it does it both when laser engraving the lines for the first test and then sometimes it will laser engrave but when the camera goes to check the work it smashes into the work surface.
I have turned it off and waited. I have unplugged the module and I have hooked it up to my lap top. Nothing seems to work.
Sorry if this is too basic and you’ve already done this, but did you take the lens hood off? It’s only briefly mentioned in the online manual. If the focal length is too low it’ll crash, and the online instructions say take the hood off first. You could also try and manually set the laser height to around 23mm, which seems about right for most people. If you’re significantly less than that it’ll probably crash.
Make sure you’ve updated the firmware. (2.9 is the most stable)
Verify that your cables are correctly connected.
Double check that you’ve assembled correctly - bed frame should be nuts down. Proper screws. Linear rails centered and properly seated. Head attached to the correct screw holes etc. (You can post pics if you want us to see if you’ve missed something)

@sdj544 forgot about the nuts - that will raise the bed several mm. That’s a good suggestion, seems much more likely it’s that.
Hi Brett,
I don’t even get to the part to measure the lines. It will laser them, then lower and smash into the bed.
I did not take off the laser module or hood.
My focal length is 24 mm.
I do not have the latest firmware so I will get that going today after work.
bed is nuts down, screws are in and everything is level.
I will take a video and upload it.
If you manually jog the controls on the touchscreen so that it’s close to the bed, Z height wise, about what Z value is that?
My focal length is also about 24mm, and if I jog to a Z height of 24 (without the lens hood on, I just keep mine off) there’s like 5mm or so of clearance.
It will not let me go up in the z position. Only down.
I don’t follow, did the machine not home?
That coordinate of Z 34 seems a little high for how close it is. I know you said the nuts are down, but could you post a picture of the platform underside anyways?
I’ll try the lens hood. It’s like it that much too close to the material
I can only move the x axis (laser module right?) down it will never move up.
I am using this to set up https://youtu.be/Spya1Zs2xsU. So I touch the laser to the work surface when setting to work table height correct.
I assume i am doing something wrong. This is my first attempt at anything with this machine.
I took the lens hood off and it lasered fine
It checked the lines and failed so I picked the best one
Then It lowered again and smashed into the table
You picked the line on the far right? The right side is getting higher, so that’s indicating it’s too close to the bed. If you picked the far left that would lower the laser closer to the table.
You can always go into the touchscreen settings->laser focus (or laser height, can’t remember the name exactly) and raise it 5 or 10mm.
Also, can you post a picture of the underside of the platform?
The far right looked the most crisp to me but honestly they all look the same but that makes sense.
I can’t set the original manually because I have to finish the initial laser set up. But in the set work origin I cannot go up on the z axis at all.
I think there is an issue where the machine thinks it is versus where it actually is.
Thanks.
I think the height is determined when you do the calibration card. I do that without the lens hood also. There very well may be something wrong, I don’t know. But just pretending the lens hood didn’t exist worked for me.
Also the auto calibration is super buggy sometimes, try setting it in the touchscreen settings to manual calibration. It’ll ask you to jog up and down to get the tightest laser spot, then do the +/-5mm pattern from wherever you set. That’s what I do because half the time it chooses the wrong line automatically. Some people here on the forum have told me it’s a firmware bug but I don’t want to downgrade since it’s like the only problem I’m having.
I am working on test laser prints and it seems to be working. However, when I over the z axis is moves 20 mm and smashes into the work bed.
It appears my largest issue is with moving up in the z axis, the machine does not do it at all, that is with the firmware right out of the box and right after the update to the newest firmware.
I had the same issue, I solved it by removing both top caps on the Z actuators, clicked the switch on each, then replaced the caps. After doing this, the Z moves both directions. Hope this helps.
Thank you! Support did get back to me and they sent me instructions on how to troubleshoot the issue. I did click the limit switch but it still gives me the same problem. I am getting a new rail via post.
I am glad it worked for you!
I typed M119 into the Code the console portion of Luban and got this: (not my pic but from support and is the same issue)
From their support told me to do this to troubleshoot:
Please follow the below instructions and send us a video of it.
Remove the X-axis linear modules.
To check if the converter or the linear modules is faulty.
So from here when I dismantled the end of the defective Z axis linear module this is what I saw. That is the Z axis limit switch activated. It clicks when pushed, and Support asked me if it did but did ot tell me what it means. Another user said he licked his and it works normally, but mine did not.
Snapmaker is sending me a new linear module. Should be sent in two weeks and get here in two weeks.
I hope this helps anyone else who has this problem. Mine was like this straight out of the box.
