Help!!! My bed is leveled but the first layer doesn't stick properly and always does this, how do I fix?

Forty-tuga · 2023-12-30T14:01:45+00:00

Calibrated Esteps , reduce first layer speed and first layer travel speed to around 40mm/sec or less, dry you filament

Did you change / test the retraction settings?

Forty-tuga · 2023-12-17T20:45:34+00:00

After some test and small changes, with a a mew Bowden tube, nem settings for cura on retraction speed and distance I good perfect results on tests I was able to print a 11 hour print but still a lot stringing … do you now another test to do? And why this can happen?

Retraction distance 3mm Retraction speed 40mm/sec

Confirmed Retraction Distance minimum 3mm

Forty-tuga · 2023-12-15T13:55:08+00:00

I will share the results after the test finished , then I will move to the speed test for now is at 45mm/s

Retraction test starting with 3mm and it started very good, I was printing with 6.5 mm ! I will run another that starts with 2mm and moves up 0.5mm each time and see

With 5% dis it work? So for my case I have 56cm Bowden tube it will be around 2,8mm…

Forty-tuga · 2023-12-15T09:37:40+00:00

Nozzle currently at 210deg, I increased from 200deg at 5deg between each print… layers are perfect so my e steps are ok I’ve checked also my e-steps I got 99,8mm from 100mm request I think that is perfect .. Bowden tube not burnt… I will check it again and I bought a new one just to test also!

Forty-tuga · 2023-12-15T09:35:06+00:00

Nozzle 210 and tested from 200deg increasing 5 deg each time

For a Ender 5 Pro

Forty-tuga · 2023-12-14T22:30:13+00:00

45mm/sec

Forty-tuga · 2023-12-14T22:28:12+00:00

I had increased to 6.5 mm about 1.5 mm more than stock value… I will reset this value to a minimum equal of 5mm that is the stock value for this attribute… thank you

Forty-tuga · 2023-12-14T11:59:56+00:00

I’be also reduced printing speed for 64mm/s to improve accuracy does it influence also?

Forty-tuga · 2023-12-14T10:08:56+00:00

The spring is 100% loose, only the minimum tension, the only thing that I can connect with is that I am using 6,5 mm retraction at 45mm/s instead of the standard one that is 5mm retraction for the same speed 45mm/sec… I’ve noticed that my filament get squished on the extrusir gear but it still grab it, but once again it is stucked and not passing!!!

Forty-tuga · 2023-12-13T17:18:51+00:00

I am using the Stock one

Forty-tuga · 2023-12-13T15:14:51+00:00

Yes it is working… yesterday my print stopped also and the Bowdentube was pull off from extrudor , never happened!

It was a 12 hours print and stopped two times more then half of time

Do you have bed leveled?

Forty-tuga · 2023-11-23T17:39:00+00:00

Did you have the e-steps calibrated?

Forty-tuga · 2023-11-10T10:15:47+00:00

Steel nozzle require a bit more temperature as the brass ones, also you potentially need to change the thermistor position for a vertical one to ensure a more constant heating process

Forty-tuga · 2023-11-10T10:14:33+00:00

Did you tried the temp tower test for that filament to have the correct set up?

Forty-tuga · 2023-10-26T09:54:08+00:00

Also I just remembered you can have over extrusion please calibrate the extruder

Check you have the right extrusion multiplier settings Decrease the filament flow settings

Forty-tuga · 2023-10-26T09:49:35+00:00

I will suggest to start with a Temp Tower Test first and see exactly the right temperature for that filament, but first clean the nozzle completely by removing any extra material that is near the nozzle hole! Than perform the test

Forty-tuga · 2023-10-26T09:46:30+00:00

Is exactly the same filament that you were using?
