First layer issues after Ratrig Toolhead upgrade
So, I splurged and bought a new Ratrig Toolhead with all the bits & bobs. Rapido UHF, Orbiter 2, even got myself a beacon. Everything installed and homed in - and that is when the trouble starts.
For the love of me I cannot get a decent first layer. The blob-tower nozzle wipe works fine, but already when printing the edge of a first layer it goes to pieces. The rim looks under extruded, and the nozzle starts to roll up the PLA. I'm lost - any advice would be greatly appreciated.

Are you of RATOS 2.1 RC? If not I would suggest installing it and go through the calibration procedure.
I'm on the main RatOS 2 version - I looked at the RC site; is the install just the same with balena etcher?
lol and now it sends my video's
oh just found the image on the site. Will try it
Some people have had problems with the latest balena etcher, if so, the earlier .18 version is reported stable. Also, make sure you are on the Helge 2.1 calibration page on github.
What cgrr said, if you're using Beacon you should really grab Ratos 2.1
Right, installed the RC - will keep you posted on progress 🙂
Good luck!
@cgrr what do you mean with the 2.1 calibration page? Is this a separate download?
Not a separate download, but usage documentation, i, e. g-code changes https://github.com/HelgeKeck/RatOS/blob/documentation_v2.1/site/docs/slicers.md#orca-slicer among otthers, just go through the whole thing.

awesome, thanks for the info
No worries, here is the one for the Beacon https://github.com/HelgeKeck/RatOS/tree/documentation_v2.1/site/docs/configuration

cool, just did the PID tuning moving to the beacon now
It started off a little better but after this the same troubles. I'm going to leave it for tonight and try again tomorrow 😉
thats a really inconsistent skirt. Good look on the morrow
Since your corners are lifting it would seem that you are too high or the filament is not adhering. One thing you have to be careful about is crud accumulation on the nozzle because it will throw off beacon touch offset.
any clues on where to start looking? The nozzle is clean, I'll do the z-offset old-fashioned way again with a pieze of paper and microstepping. I'll also clean my build plate (again) and do an extrusion test just to be sure.
Is your Beacon touch enabled in the config? My first Beacon touch z -offset auto came out better than I ever did the old fashioned way. Which filament and did you do the temperature compensation offset?
I'm using the default beacon setup that the RC1 provided me now; it does do a beacon home when I start the print. I ran the full suite of tests last night for the beacon. Filament is Kexcelled Basic PLA. One of the things I'm trying now is to slow the first layer down by a bunch to see if that makes a difference
The brim is a lot better, and there is no rolling of filament; still some adhesion problems by the looks of it
the fact that reducing the first layer speed from 60 to 40mm/s does this starts to make me think that it's extruder related
ok so extrusion test was spot on - 100mm exactly extruded.
onward to layer 2
Slowing down the first layer and upping the temps 10c seems to have done the trick (combined with the 2.1 Beacon tuning)
Was 80% through a perfect calibration cube when it got loose from the build plate - but it all seems to work now. Thanks for the assist @cgrr and @TheTik
