Gaps in first layer.
Think it must be mechanical
Hit end?

I don’t own an SV08…but gaps usually mean the Z-Offset is off.

This later on… The Sovol SVO8 has a calibrateZ routine to check and this is OK. I thinking hot end issue

I use a Heat soak for 30 minutes as recommended, thanks

5

Hotend temp, filament type, enclosed…??

6

PLA, 220 C nozzle, 65 C heat bed which is soaked for 30 minute.
Calibration Z routine used, bed mesh used. Enclosed

Probably too hot (that is just a guest but 220 for PLA + enclosed, that is a lot). Your print look like very “gummy” (like TPU print). For PLA with SV08 i use 200° for the hotend and 60 for the bed (without enclosure and in my bassement : external temp is around 15°c). May you try a temp tower ? (with doors opened)

PS: oh, and, another way, did you check all screws are well tied ? I asking because if your nozzle moving, that may give also something like that (i already had that because of vibrations).

You have to leave the door & top open for PLA. Also no need to heat soak.
Your going to end up clogging up the nozzle.
Try printing at 210* for PLA & 215* For PLA+ & Silk filaments.

Ok, I’ll try this. I’ve done a big print,5 hours, using pla before with the exhaust fan on and the front top glass short off worked well front doors closed no heat soak that Sovol say use it 300 size plus

Heat soak used on a bigger print

After gaps in first layer a fix

What slicer are you using and what are the settings that you have in the slicer?

I am asking this because I had to update Orca a few weeks ago and some settings were “discarded” I guess. So I detected that the first layer infill needed some tweaks. It was in 90mm/s and I set it to 106mm/s

As stated here

However, If I don’t preheat the bed for long time, this does not always work.
My printer is without the enclosure.

Like I said in another post this does not look good at all.
The complete print seems to suffer from under extrusion and delamination.

I think you should check the complete filament path (anything from filament spool to hot-end) for blocking, misalignment or malfunction before trying to fix first layer issues

  • edit -
    I watched you video and see you also suffered from the extruder pin misalignment, I hope that fixed it

My video shows how bad prints can be before fixing the pin in the feeding arm
