Z axis calibration, instructions

Hi

I noticed an error on your instructions to calibrate Z axis.
“If you turn to the right then the build platform will stop a bit higher when you perform an autohome command.”

Actually if you turn right (=clockwise) the platform will stop a bit lower. This caused me to broke the Buildtak… I hope you update instructions to prevent this from happening.

Atleast in Finland and Sweden we think right is clockwise. And turning the bolt clockwise will pull the lip downwards so platform have to go higher.

Thanks

I noticed a similar confusion. Usually you screw ‘in’ (clockwise) to make it tighter, or out (anti-clockwise) to loosen something. How this maps to ‘up’ and ‘down’ is the thing that confused me.

Perhaps it is good to add a picture or diagram to show proper direction?

I had no idea what that meant either. Does it mean facing the printer from the front, or from the back where you probably working on it?

The screw located in the Z stage moves the small plastic piece up or down. When you move it up it will reach the endstop sooner and stop the bed sooner so the distance between the nozzle and the buildplatform increases. If you want to decrease the distance between the bed and the buildplatform you need to lower the plastic piece.

I understand how it works but could you update the instructions? It would prevent people destroying buildtaks and nozzles.

Hey Velleman you have wrong instructions! I absolutely agree with Max. You have to use clockwise or counterclockwise term with this instruction. Right or left is totally wrong and can cause confusions. You can turn screw CW or CCW and there is no unclarity about it.

Just my opinion here.
If they put CW or CCW in the directions then the question will be when your looking down on the Z axis or looking up at the Z axis.

Maybe tightening the screw of loosening the screw or just put an arrow on the picture
Any way they write that part someone will be confused.

[quote=“Wrong Way”]… just put an arrow on the picture[/quote]Exactly, problem solved. But will Velleman do it? :wink:
