Priming & Printing with .6 nozzle

Just switched to the Rapido .6 nozzle (changed extruder setting in config) and priming and printing is borked. Priming blob seems much smaller and doesnt stick to the bed, nozzle scrapes when starting print and print does not stick even slightly to the bed, most of the time it blobs around the nozzle. Had my .4 singing before this, please help

nozzle scrapes when starting print
Did you recalibrate your offset?

yes, of course, wondering if the math for adaptive mesh works for .6 nozz\

works fine. Machine size should not be the issue. I run a Rapido UHF, .6 nozzle, VC500. Prime blob works as expected.

mesh is not related to nozzle size 🙂

Priming works fine with 0.6 yes like the others said you need to redo your z-offset when you change nozzles. PROBE_CALIBRATE

ive done this a few times... for rapido UHF .6 nozzle, do you screw the thing in then back-screw the nut? ...the larger hex

yes Make sure you tightened that nozzle properly with a 2Nm torque wrench

indeed You want the nut touching the ceramic so that it transfers heat as much as possible If your home your printer and do G0 Z0 with a paper underneath, is the nozzle lightly touching the paper? Make sure to preheat nozzle and bed first

yep, noz at 150, bed at print temp (pla 60) testing again Anyone know the diameter of the Rapido UHF nozzle that comes with the RatRig VCore 3.1 default kit, is it the .6? I am struggling to get the UHF nozzle to print anything. I thought it was .6 but I am at a loss to figure out what is wrong with my printer since the original post anyone? having rebuilt my hotend once again, I am still printing pure garbage! starting to hate this thing, (dreaming of the 3 bamboo labs printers I could have had)

so the UHF nozzle in the rapido box that comes with the default kit is .4? there are 2 nozzles, a smaller one that is attached and another one in the box so this is incorrect, thanks. rapido UHF comes with a .6 UHF nozzle in the box, thanks. Selling this garbage!
