I had dialed in my PLA/PHA to 195 and 40 on the bed.
I leveled the bed cold and then heated bed and nozzles and leveled again. The reason for the cold level at first was due to adding the PrintBite I needed to adjust as it is thicker than the blue sticker.
Then I did the hot leveling. I always end with hot leveling. I have adjust and adjusted. I will tighten up even more on it though. I have been leveling using the leveling card QIDI sent. I will go back to paper.
Heating my PLA/PHA to 205 resulted in a melted mess. I dropped it back to 195 and heated the bed to 60 degrees and added a raft. So far it is sticking longer than other prints. I will know for sure in a few more mins the quality.

you're not even close on the calibration to what I use.
The front bead should be pretty much just a flat strip. Yours still looks like a round bead, you should not need a raft. I haven't used a raft for anything since i stopped using abs. I've used a couple of brims over the last two years - but it's that small a number and never needed anything like that with the printbite.
that said I have yet to try a pla/pha blend - so it could be the pha that's causing the problems - might give you a little more shrinkage than i get with decent pla. But you're calibration is much much looser than anything I've ever used on any surface.
I use 90gsm paper and it's a fairly tight fit between the printhead and the bed.
Quite like the new pattern they've put on it - mine's just plain white.

I like the pattern they have on it as well. Makes things easier to see on the OctoPi cam as well.
I have to tighten it up again. I was off the last 24 hrs or so and have not done anything. Been sick.
This last time the bead was flatter but not as tight as you are describing. I think if I go nice and tight it should help as you said. I will let you know how it goes in a bit.

I have found I have to treat the PLA/PHA like ABS temp wise. I am running it at 220 ext, 90 bed. Test print was ok.
The calibration test was done at 210 ext, and 70 bed. Slight warping. With the temps hotter it should help. I also put the front door back on but left the top open. It is rather cold in the room.

I'll have to get some of the pha blend to test.
Sounds like the same sort of performance i get with esun pet-g.
How fast are you printing your first layer ?
I tend to go back to 10% for the pet-g, whereas I can run the pla at 30% for the first layer.

I cut the print speed back to 15% for the first 4 layers just to be safe.
I have been in touch with MetltInk as well last night. I am trying some changes based on that info now.
The filament definitely needs some higher temps than PLA alone. I am able to make chain units with a raft, Benchy at its basic size. Once I get over those sizes in either diameter or height it goes nuts and lets go. I have the bed leveled so nice that I have seen improvements even in my ABS and PeTG prints.
I will keep working on the PLA/PHA.
MeltInk gave me a link to a great thread as well for settings people tried with.

Some people seem to have less warping with out the blower on but when I tried with it off or below 60% after the first 5 layers the warping hits fast and nasty.
Experimenting is fun I was just surprised at the pain with the MeltInk once I dialed it in with Benchy and the two color frog. Things bigger seem to mess up.Editor in Chief

I've been getting much better results with PrintBite and MeltInk PLA/PHA.
Top cover on the Qidi Dual, nozzle 210, bed 70, door open, layer 1 thru 3 fan 0, 90% the rest. Speed 40mm/s, 0.95 multiplier, 20% infill, . 2000 .
Still warping on bigger parts but killer detail coming in now.
I also ran a test with some new Prospec PLA , amethyst. Same settings just to compare. Came out great , no warping , great details that the camera is not even picking up due to the translucent quality .
PrintBite is kicking ass with everything except for the pla/pha and that I'm getting dialed in .
I will post some pics in a few mins still uploading .Editor in Chief

yeah for pla it's just brilliant.
Going to do some pet-g today, need stronger threads on a project :-)
Please explain to me how to...
