printer restart on its own

[Eug 0]

printer Ultimaker 2+ Extended, PLA 2.85mm

after I start a printing, usually I set the nozzle temperature around 195°C.

it happened several times now, while I was doing the setting, the printer restart on its own.

did anybody see this problem?

This is a common problem. It's almost always the power brick.  If the brick senses that you used too much power it shuts off.  But only for about 1/4 second and then power comes back on.  This appears to be a plain old reboot but is really a power off/on very fast.

 

If this printer is less than a year old I would try to get a free one from your supplier.  If not you can just buy the power brick.

 

Until you get the new brick you can avoid using the bed and instead use a cold bed and blue tape washed with isopropyl alcohol.  Your printer should have come with blue tape for this purpose.

 

Alternatively you can use the power budget feature in tinker marlin which is a fantastic alternative firmware for um2+ extended.  You can download it here (you want the 5th one down of course):

Go into power budget.  I believe for normal printer you want:

budget 180W

bed 150W

nozzle 30W

 

With the above settings the budget will never limit power.  so then you just lower the budget a bit:

budget 160W

bed 150W

nozzle 30W

 

That should be plenty to avoid tripping the power brick.
