[Faulty prints]

And temperature? Try to raise the temp 10C just in case, anyway it's quite slow.

Maybe some user with print experience with UM2 can pinpoint your problem. But I think you are just under-extruding due one or more of this possibilities:

a) Lack of temperature

b) Filament size might not be 2.85mm perfect. Can you check that isn't more or close to 3.00mm?

c) You might need to clean the feeder knurted bolt

d) You might need to check the Bowden tube status to double check it's in good condition.

 

Temperature 215 degree celsius

bed temperature 60 degree celsius

I am facing another problem with my prints. .

Kindly help me.

Umm the print error was due heat? What's the room temperature you had? Also, you mean heatsink on the stepper chips or the actual motors?

I did also install some small heatsinks on the boards just in case, I'm a bit over cautious since the pst year summer made my z chip to miss steps at a room temp of 32-34C. fast fix its to remove the board cover or place a fan hitting below the printer. But for me that only it's a problem after 2-3h print time when the room gets really hot. Now that I have 3 printers I just use airconditioning to keep the room at 28C

 

Thank you neotko.

The temperature in the rooms is around 35-40 degree celsius.

I plan to put a hit sink with fans to the motors . Should i go ahead?

Looks like you have problem with layer shifting which is most often caused by the pulleys on the motor shafts being loose:

Also, what is going on with your bed? It looks like a horror show, is that a ton of glue or what is it?

 

Thank you for the suggestion. My printer had the problem of heating up of motors. I changed the current settings from 1300 mA to 1000 mA. Now its working fine.

I want to know does reducing the current to such extent can damage the motors in long run?

How much low current settings are acceptable by the motors?

Is there any way to cool these motors by attaching heatsink and fans to them?

Hi and welcome to the community

What kind of printer(s) do you have?

How long does the backup system need to take care of running the printer(s)? Is it usually some small power failures or long ones?

hi. I have ultimaker 2. the backup system needs to provide power for 15 minutes in the worst case situations.

Hi. I print medical models which take approximately 24 hrs. I am facing problem with the type of back up power supply required to prevent failure from frequent power cuts and unstable power supplies in my area. Kindly suggest me the appropriate type of power back system required. Do I need an online or offline uninterrupted power supply unit? Please help me.
