I have a problem, when I’m printing and the power goes out, or I decide to stop the machine until the next day, when I turn it back on the printing continues in the same place, great, but it always leaves a visible mark of where it stopped and where it continued, is it possible to reduce or avoid that line?
It seems as if a problem was occurring even before the switch-off line. Maybe switching off and on has exaggerated a less-than-optimal setting.
The photos are not very sharp though.
No, there was no problem before I turned off the machine. It always leaves a line when I turn it off and continue the next day, no matter how much printing is done. I think it has something to do with the temperature, from being hot, to cooling down, and heating up again, it makes a visible line, and you can also see it with your fingertip. Has this happened to anyone else?
There are similar problems a few lines below the switch-off.
No, before and after continue printing is perfect. The line only appears exactly at the point of off and continue.
@Boxkite is from my point of view correct. Look at your second picture and you will find partial underextrusion or something similar.
If I pause and resume it wents fine every time so I think the issue comes from cooling down.
Maybe reheat your printbed to your desired temperature for let’s say 1 hour to let the print expand.
Personally i wouldn’t interrupt the print like this because of the risk of loosing the print because of thermal detaching.
The ideal is not to stop printing, but at night it makes a lot of noise, that’s why I stop it and continue the next day, but it seems that there are problems with the temperature doing that.
Did you ever try reheating the bed for 1 hour?
No, I would have to see how to warm up the bed for 1 hour
You can test the temperature more easily by stopping and immediately restarting, rather than warming the bed for an hour.
If you stop the machine and continue quickly or in a few minutes, there is no problem, everything goes well. The problem arises when you stop the machine for several hours and it cools down. But I don’t know how to heat up the machine for 2 full hours after restarting it, since it doesn’t offer that option. The machine asks if you want to continue and when you say yes, it starts printing directly, and that option or screen cannot be removed. You can try it if you want with a small piece.
Didn’t think about this…
I think you should be able if you are connected over usb using a terminal and sending the gcode directly to heat the bed.

I am not sure what would happen if you connect over wifi, I think this would abort the resume process.
i connect luban via wifi, it sends the gcode file via wifi, i disconnect luban, start printing, turn off the printer, turn on the printer hours later, then it asks you if you want to continue printing or not, you have no way to change the printer screen, you can only choose to continue printing or cancel. if you continue printing, it heats up the bed and automatically starts printing, there is not much power of decision. it is a problem that the machine can not solve this problem easily.
Idiot me. If you resume, simply press pause and it will heat further.
Yeah, okay, I’ll try that next time and see. Thanks.
I have had the same thing happen a couple of times
and you knew how to solve it?
No it still happens with some filaments
Ok ok, you have to try to restart and wait a while and then continue, so that way maybe everything will heat up so as not to create the wrong print line.
Will give that a try also if you paint your print it makes the line much fainter so it can’t be seen except by you
