Re-adjustment flat level of x-axis, if you hit the table

[Kazuyuki]

I’m using SM2.0-A350. If you once hit the table hard by the nozzle or cnc-tool, you should level x-axis linear module again.
I found tilt x-axis when I carve the object. It cut well in the left side, but insufficiency around 0.5mm in the right .
I came back to the install manual again, remove x-axis linear module, slide both z-axis linear module to the full-top by hand. Then install them again. Finally, the level fixed again with only <0.1mm level. Is it the right way?
I remember I once hit the table hard by cnc-tool in the right side, the tool was broken and maybe the right side of z-axis was misaligned(rise), I guess. Of course you should check the table, too.

You are absolutely right.
For me it is enough to push the x-axis to the end of the z-axis by hand when the machine is powered off.

You shouldn’t have to remove the x-axis.
For me I’ve never had to do anything but home on mine, but some people have different results.
Raising the x-axis all the way to the top manually can work.
Search the forum for ‘tramming’ for the other way of doing this.

Thank you xchrisd & sdj544. I will do better way in the next time based on your advices.
I’m not a native speaker so I could not hit ‘tramming’ as a key word, but I will check!
The SM2.0 connects 2 liner module as simple parallel, we don’t have any software controlled ‘tramming’ adjustment. It’s a one discussion point against the implement costs or other difficulties, isn’t it?

@Kazuyuki

we don’t have any software controlled ‘tramming’ adjustment

And we never will. Tramming is a hardware procedure informed by measurement tools.

Hi eh9, All right, I should purchase the ‘dial gauge’.

[sdj544]

No need for dial gauge .
See post 34:

Carriage Tolerances - Unusable Over Distance >75mm From Center

Just thought I’d share a picture of how I tram X now. This is fast and precise to do before I turn the machine on and home. [image] Yesterday I deliberately left it 0.01mm low on the close side, and I could easily slide the far block under X, but the close side was too tight and the block hit the side. On the touchscreen I raised the Z height by 0.1mm and was easily able to slide both blocks in. Not making any claims on exactly how precise this is, as I’m aware of a slight rotation in the Y m…

He’s using engineering blocks but any two things of the same size (soup cans, coke cans have close enough tolerances) will work.

@sdj544

coke cans have close enough tolerances

Just make sure not to “pop” one. Imagine the mess that would be…

Thank you sdj544 & Artezio. That’s smart, I can make a good saving! I’ll try.
And I agree, handle with care if the coke cans on the machine.
I found I have spent not enough time to read whole of the forum. Thank you again.
