Regular surface distortion pattern towards end of larger first layers VC4
I didn't print enough with the stock fan reversed to confirm if there was ever going to be a clog. I printed maybe one or two flat sheets to test leveling. There weren't any odd behaviors in that short time, but again I was nervous about taking the chance of clogging it by pushing it.
So I switched it for the fatter fan (reversed) and the increased airflow I could feel instilled confidence, but by this point I already had ti tube on the way. The vibration was more of a noise complaint than anything. I printed a few small test things, like bed leveling sheets, and also the parts needed to install the ti tub, without issue.
I made sure to orient the ti tube parts along the Y axis so that the X didn't have to move as much and can stay in that heat soaked area for the majority of the print. Having the long parts oriented along the X axis were impossible to print.

Yeah, I tried scan compensation and heat soaking. Heat soaking worked about half the time. Scan comp didn't do anything for me. Reversing the fan also did okay but I was nervous about heat creep. Even put on a 4020 fan to run reversed, but that added a ton of vibration.
I installed the titanium tube yesterday. So far, seems to have solved the problems.

Interesting. Not sure if that is my issue though. i have a healthy amount of bearing oil on my rails.

ah sorry for my ignorance. I did not read that pinned message, and therefore did not realize the hotend is the culprit. I will try that stuff!

This is my first printer with rails, so I'm genuinely asking. Bc i'll be sad if the TiTube doesnt solve the problem since its seeming like heatsoaking isnt doing it either

hmm i have the tools. Let me see what the DMM reads when i put the bead in the rail.
isnt this a bit odd, though? Using linear rails on 3D printers isn't a new concept. Do Vorons or similar have this issue?

I tried to edit this image to make it more obvious. The first third (right of red line) will print perfectly. After that, it has the texture that others seem to be experiencing and relating to bimetal affect, but preheating isn't working. Let me know your thoughts.

Regular surface distortion pattern towards end of larger first layers VC4
So I have yet to receive the TiTube, but I am experimenting with heat soaking and i still am unable to get a reasonable first layer.
I placed a temp sensor and fans in the chamber to circulate. Preheated the printer until the temp sensor maintained 38C for 30min (this is as hot as i can get the chamber to stabilize at without adding a dedicated heater) This process took around 3hrs to heat up and then let soak at temp.
I am still getting the same rippling affect on a first-layer print. Any other solutions to try?

Im looking for some level of certainty that this is worth the $100 in terms of reducing the bimetal affect on prints and reducing the need for long heat soaking.

Hello, is the general consensus that Ti Tube improves the bimetal effects? I have one loaded up in my cart

Okay, so the lift is intentional. What if this was reduced to maybe Z0.1? It just seems that there is still always residue on the nozzle tip for myself and maybe the OP as well.

I dont mean to hijack your thread @Flo@GRNbms. I do feel this is related because i had similar issues as what you originally posted, and despite being corrected in that my "fix" isnt the ideal solution, it did work, which tells me we are on the right path, perhaps?

First layer problem
oh, yes it is definitely going through the motion of wiping. That was my misunderstanding in what all gets turned off when i disabled "variable_beacon_contact_start_print_true_zero'
Now with it re-enabled, I am wondering if there is a better wiping method? Mine will tap the bed, then raise a slight bit before slowly moving from left to right. Should the nozzle be dragging on the bed, or is this how it should behave?

This is the condition of the nozzle at the time of contact probing. The wipe isnt wiping

Thanks for this info. Perhaps i just never noticed the toolhead executing a wipe before contact probing. What lines in the macro initiate the wipe before contact probing? i am looking at mine, which is just the default RatOS, and i dont see a wipe command.
