#Ender 3 V2 speed and temps

I have an ender 3 V2 with klipper and input shaping, I have been working with high speed printing. I have a creality spider v4 that is for some reason unable to maintain its temp while printing with a speed of 300 mm/s. I get the whole error that states it is not heating at the expected rate, but I cant for the life of my figure out how to improve my performance, I've tried all the obvious things. (all with PLA at 280c to maintain high flow rates)

It sounds like you may be pushing the limits of your printer's capabilities with such high printing speeds. Here are a few suggestions to help troubleshoot the issue:

  1. Make sure your hotend and heated bed are reaching and maintaining the correct temperatures before starting the print. Ensure that the heating elements are functioning properly.

  2. Check if there are any obstructions in the hotend or extruder that may be affecting heat transfer. Clean the nozzle and hotend assembly thoroughly.

  3. Ensure that your printer is properly calibrated for high-speed printing. Check your slicer settings and firmware parameters to see if any adjustments can be made to improve heat management at high speeds.

  4. Consider upgrading to a higher wattage heater cartridge or adding additional insulation around the hotend to help maintain temperatures more effectively during fast printing.

  5. If you continue to experience issues, consider lowering your printing speed slightly to see if that helps...

@stable dusthigher power heater for the nozzle

#

stock is probably 40W, might want to try a 60W. The upgrade may require to use a mosfet board due to the increased current, check the board specs to see if you can use the 60W

I'll see what I can find

#

the one I have (from what I can find) is 70 watts and working fine, but I dont think it is operating at 70 watts

#

is it a tube or ceramic thing?

stable dust
#

ceramic

#

thats the creality page I bought it from

dull terrace
#

ceramic.... yeah... it do not heat to 70W

#

it is closer to 40W

stable dust
#

I cant find any reliable sources on the actual wattage

dull terrace
#

it "is" 70W.... when cold.

#

the power then drop drastically as it heat up

stable dust
#

interesting, regardless, I still see others with the same hotend printing fine at these flow rates + the actual store page claims to be able to do 100mm/s faster than I am doing

#

I wanted to upgrade mine to a ceramic heater, but ended up not because of that effect... I would have got less power than right now...

#

what kind of nozle do you use? brass? hardened steel?

stable dust
#

I have tried a few, steel lasted the longest but also under extruded a lot while brass did not

dull terrace
#

brass have a better thermal conduction than steel by far

stable dust
#

yeah, I know, I assume thats why steel performed in that way

dull terrace
#

like 25% better flow rate in my own indirect tests for brass

but the heat loss is too much, it still cools too much even with part cooling
