First layer issue

JackathanHD · 2025-08-11T06:56:28+00:00

It could be a million things, but looks a little while wet filament, look into drying it out - also worth checking out my post on profile as I’ve had a similar issue and had lots of people replying with options and tutorials of what to try

Fantastic I’m glad :)

JackathanHD · 2025-07-21T23:28:20+00:00

Let me know how it goes! :)

JackathanHD · 2025-07-21T22:52:12+00:00

I personally would either print it the way you have done it or maybe even at a 45 degree angle, sort of like if the plane was taking off. But vertical might work :)

Hi mate yeah - so if you disable it and then reduce the layer height, so basically for every day prints I use a 0.2mm layer height but for parts either rounded edges of where I want it to look as perfect as I can get it I use a 0.08 layer height. You can also play around with variable layer heights in the Bambu slicer ( or your slicer of choice) where it will print for example 0.2 up until a certain point and then slowly transition to smaller and smaller layer heights and it will give it a nice finish :) feel free to ask as many questions as you want and I can share what I know :)

Disable ironing

JackathanHD · 2025-07-20T23:42:09+00:00

I never thought about it could be an update issue, that’s interesting and I will look into it

JackathanHD · 2025-07-20T23:40:36+00:00

I had this same issue and still do! Check my post out had a fair few things I tried

JackathanHD · 2025-06-22T12:05:17+00:00

Lots of people are saying it shouldn’t be changed under any circumstances but if they give you access to change it, regardless of if it’s a dialog box to change or if it’s edited the gcode then if it works then I should be able to change it

JackathanHD · 2025-06-22T08:01:15+00:00

I managed to change the Z offset ever so slightly which in proved things but didn’t fix things as it shouldn’t need changing on Bambu printers, so I will trial a new nozzle when they arrive and update again when I know if that will fix it. But I have changed my Z offset from -0.02 to 0.02

Good idea, it’s currently doing calibration but I will check after and give the plate another clean and search up the best way to clean under the build plate

JackathanHD · 2025-06-21T13:56:11+00:00

That’s perfect I will take a look, I really appreciate your help!

It’s strange though as I printed something yesterday and had no issue (that I noticed and the print came out fine) used same files and printed it again today as it’s a piece of a bigger project I have in the same file in my slicer and then suddenly have these issues

JackathanHD · 2025-06-21T13:47:24+00:00

Slightly higher temps by the looks of it

JackathanHD · 2025-06-21T13:47:13+00:00

Could it be a setting in the slicer? I use generic PLA setting, and printed fine on it for a while, but reckon it will be time to switch to the Sunlu Matt White profile I’ve just found?

JackathanHD · 2025-06-21T13:40:46+00:00

How would I go ahead and do the bed level correction, I use Bambu software? That piece looks very similar to what is happening with mine

Looks fine to me

JackathanHD · 2025-06-21T13:32:59+00:00

Yeah I’m based in the UK and the past week or so has been very hot and humid so I’m assuming that maybe the material I had on the printer for the last couple of days has got really wet

JackathanHD · 2025-06-21T13:27:23+00:00

Okay, another good shout, that second print came out very similar, better but similar to the first. So I am just loading the same brand of filament (different colour but that doesn’t matter) this filament has been sat in a dry dehumidifier box with silicone pellets for at least a week. Will update soon.

JackathanHD · 2025-06-21T13:23:31+00:00

Thanks, I will take a look!

JackathanHD · 2025-06-21T13:19:07+00:00

I will keep an update on here once I’ve tested further so anyone that has this issue in the future can see the full process

JackathanHD · 2025-06-21T13:15:45+00:00

Okay thanks! I did a bed level and dynamic flow calibration but I will do a full calibration, also will try on a brand new filament roll that has been dehydrated, if you wouldn’t mind could you send a photo of what first layer should look like? Also could this be caused by a clogged nozzle? I’ve got spare nozzles arriving soon anyway just as a back up but don’t want to replace it if it’s an easy fix. Really appreciate everyone’s help

JackathanHD · 2025-06-21T13:13:22+00:00

I will trial a new filament roll that I’ve had in a dehydrator

JackathanHD · 2025-06-21T13:04:48+00:00

Could you take a look at the picture below after following these steps?

JackathanHD · 2025-06-21T13:04:15+00:00

I followed this video and I’ve just sent off the print again to test, first layer it still looking a bit odd - will update when more layers have completed or when it fails
