Hi,
I have a cr-10 se printer that I overall enjoy, despite plenty of fails. At first it was since the model detached from the bed, I increased the first layer temperature, decreased the other layers to 195 and the bed temperature is at 60. This helps a bit, but what really fixed it is printing one element at a time, rather than one layer. Still one of the prints failed, and from what I understand, the issue is that the printing head is a bit too low. Maybe 0.05m I would like to put it up but I have no idea how. I couldn’t find any real guide for that, and the printer let’s me configure it only while printing (which means that this is a per-print config).
How do I actually do this?
Hello !
From my knowledge, you have two possibilities if you can’t via the screen:
- With the slicer, in the profile profile
- or by adding a line in the start g-code. Your printer is still by default in Marlin ?
My printer is still in the default firmware, yes. I recently updated it (from the internal setting menu). I didn’t have the time or the nerves to go through the root process.

In the slicer, try to put the value you find via the screen with this code 
M851 Z-1.25 ; remember that negative = nozzle closer to bed
(replace the value after Z)
It will force this value for each print
thanks, where do I put this? That’s my main question. In the machine start g-code?
Yep in the start-gcode ! Generally after the leveling (if there is one) and before the wipe line 
I don’t see anything about leveling (the the printer does that), I do see this which looks like the wipeline to me
G1 X-2.0 Y145.0 Z0.28 F1500.0 E15 ;Draw the first line
G1 X-1.7 Y145.0 Z0.28 F5000.0 ;Move to side a little
G1 X-1.7 Y20 Z0.28 F1500.0 E30 ;Draw the second li
There is something that confuses me, after I replace a nozzle, there is no way that I’m able to reinstall it a the exact same height. Same for if I replace a printing head or a motor or what not. This is the only way I’m supposed to update the z-offset? There is no way to do this with a regular UI?
OK, something is weird. I’ve added that line. The line I’ve added to the printer is
M851 Z-0.656
However, the printer shows that the offset is -0.651.
The print itself is fine, so far
