I never saw the pausing before with the Beta not even when platform leveling calibration was used - it seems to be a new issue.

Good theory ! ;)

I installed 1.18 and didn't go through the platform calibration as it was already manually done, but I still see the pausing.

Yeah, it seems to be a new bug/feature not related to platform calibration/levelling.

The pausing seems to help and give pause to the raft laying down, to help reduce warping

I had wondered if that was the case. Maybe someone from PP3DP confirm that this was the intention?

Ahhhh! That's what all the 'new' pausing is about when laying down initial layers for raft. I had thought until reading this something was changing with my printer and was just watching it closely. It definitely started at the time I upgraded to new 1.18, but never saw it mentioned in software release notes so didn't think about it being a new 'feature'. Good to know this was possibly intended and nothing is going bad with the printer. Thanks, -j

Maybe because many users have noticed this thing happening it's advisable to give some kind of warning NOT to overhaul you're printer. Because when I noticed I broke one of the gray rod clips in traying to figure this out. At that point there where no others with the same issue.

Phfioe :| (wipe sweat from forehead) Luckly it 's still working do!! But to keep enyone else out of the mist. WARNING

Yes, I wish they would be thorough about the features/changes/enhancements. You're not the only one to mention they thought they had a faulty printer after this update.

And I forgot: the first line to fill the nozzle is printed more towards the middle (better for Mini) and is only one line. We have Polycarbonate print sheets made for the Mini to slide in the brackets. Because the nozzle was hitting the side bracket we designed the ''perf board'' to be as high as the brackets but it is good they changed where the first line is printed.

The raft now is much easier to remove (and more clean surface after removal) than in previous versions, especially on large printed objects.
Very good update!

Unless you have a large model with low contact surface area to the raft - now my prints come loose while printing and are lost. I've gone back to 1.3/1.17/1.16 for most of my printing. Curves and underfill of corners are an issue also.

This is symptomatic of pp3dp's "Limited-Control-One-Solution-for-All-Users" approach. Users complain that rafts are difficult to remove (I never thought so) so now we have parts falling off of rafts. Around 1.15 or 1.16, some users complained about support being difficult to remove (I generally did not find this to be true) and then we got models with significantly less strength. In order to tailor our settings for a particular object/application we now have to keep multiple versions of the software on hand and try to keep track of which one is good for which parameters. The optimum settings for a big sculpture are likely to be quite different from the optimum settings for a small intricate engineering part. As has been pointed out many, many times in this forum by many, many users, giving users more control versus trying to dictate a one-size-fits all set of settings to everyone would be a much better solution.

I also noticed the jerky / pulsing motion during the raft after I upgraded to 1.18. It doesn't do this during the normal print, but my issue is that I end up with pits everywhere in the raft because the pausing when it lays down the crosses causes the plastic to droop between the bottom raft lines, which are too far apart.
