Hi guys, i’m trying to mill a pcb with a Snapmaker a350 and cnc head.  
Can i calibrate z axis to avoid the problem in the photo?  
Some videos show a wood plate to mill to produce a level bad for axis z, but it’s trivial, i hope to can do it as in the print 3d mode…

This is what you are looking for, unfortunately its no ready to run solution:

> Hey guys, I spent quite a bit of time trying to figure out how to level my CNC bed. I was under the assumption that it would come levelled or there would be some auto-levelling mechanism, but there isn’t. I went through a few failed jobs before finally deciding I needed to figure out how to level my bed. Since I spent a day getting this to work, I figured I would document it for anyone else who might be facing the same issues as me. I have the [step by step tutorial with pictures here](https://chaijiaxun.com/levelling-the-snapmaker-cnc-bed/), but here’…

> I decided to add autoleveling to snapmaker for cnc, I don’t have a problem milling pcbs but I would like to make the process easier. Right now I can mill a board in 1 shot correctly, but it’s slow and loud due to having to move at 6% speed, I’ve attached a picture of the results below: This is a good result but it could be better, namely if there was autoleveling, I could move faster and also use isolation routing. Based off Lubans source code I’m trying to figure …

It can be possible, i used a cutter to levelling z axis like in the photo  
and a 0,1 mm cutter with 10 degree to carving printed circuit
