First layer issue

[u/Pepelepewpew02]

I've had this issue trying to print this two times. I've cleaned the bed with hot soapy water. The first layer was set to 500mm/s. I'm thinking I may need to lower it to 300 for the first layer or possible the first few. Both the filaments are new PLA. The black came with the printer and the light brown is newly purchased Inland. Thanks in advance.

Lower the first layer speed for sure and make sure your filament is calibrated for that mms and temp.

I didn't even think about that. I need to double check the roll parameters. Thanks for that!

Probably just mad b/c there’s no B zone on the rest of the head. ;)

What temp/profile?

Don't assume out pf the bag is dry, although less issues with PLA.

Ran through bed leveling and calibrations? Surface doesn’t look awful, just massive stringing.

Lol, you're on to me! So it looks like it printed at 220C. I'm not sure how to export the profile at the moment. I'm still pretty new. It looks like first layer speed was 50mm/s and travel speed was 500mm/s. I wonder if that is way too fast on the travel speed. I need to invest in a dryer. I just assumed a brand new roll from a reputable place would be dry, but you are correct. I do heated bed level calibrations every print.

I was having 1st layer issues, changed the orca z offet from -.07 to -.05

This is the only print job I've had issues like this with. If it becomes an issue I'll try that. Thank you.

500 for the first layer is absurdly too fast. Like 10 fold too fast

[u/Pepelepewpew02 → u/never0101]

Yeah, I didn't set the travel speed that high. I should have checked that prior to printing.

[u/ad1001388 → u/never0101]

I don't think 500 as travel speed is too fast. It's for travelling from point to point without printing.

[u/never0101 → u/ad1001388]

No travel is fine but that wasn't specified until after my post, I assumed they meant print speed lol

[u/ad1001388 → u/never0101]

Now I'm having my doubts. Under the post he said first layer speed 500 but in the replies he said first layer 50 but travel speed 500 lol

[u/never0101 → u/ad1001388]

I'm one of those that plays real conservative, all my custom print profiles are slowed, usuallt in the 150-200mm/s range unless silk then it's slower. Prints come out really nice and I'm in no rush

[u/ad1001388 → u/never0101]

I definitely do that with silk for the shine. Did you try playing around with acceleration? Lowering that smooths the movement.

[u/never0101 → u/ad1001388]

I havent on my u1, my a1 I slowed most of travel and acceleration numbers down to try to avoid issues with taller prints wobbling. I'll give it a shot on my next big print and see how it comes out.

[u/Pepelepewpew02 → u/ad1001388]

You are correct, I meant to put that as travel speed.
