Can't home anymore after RatOS update
Hi everyone,
I did a full update of RatOS, but now I cannot home my printer anymore...
When I press "home" I get the error "Must home axis first", which I am obviously trying to do.
This is on a V-Core 3, with an inductive probe.

Gantry misaligned after toolhead rebuild
I have a 2 year old VCore 3.0 of which I recently upgraded from EVA 2.4 to EVA 3.0. I noticed the cornerns of my first print were not square at all. I checked the gantrey, when its pushed all the way forward, the distance between it and the frame has a difference of 8mm between the left side and right side. I've fully relaxed the belts, same story. I've loosened the bolts of the linear rail carriages, but I still need quite a lot of force to get it square and obviously just springs back to in horrible.
What could the issue be? I'm certain this was not the case before the rebuild. Printed parts are PETG.

Issues with Dragon HF
A while ago, I had a clog in my Dragon HF hotend. I was unable to clear the clog, so I pulled the hotend apart and got it out that way. I suspect the clog had occured in the heatbreak. After clearing the clog and reattachting my heatbreak, I had a filament leak where the heatbreak attaches to the heatblock, I suspect I didn't tighten the heatbreak well enough. So I cleaned everything, reassembled everything and printed a benchy, wich went fine. Now at the next print, it seems (I'm not actually sure) like filament has leaked again but this time from the nozzle sides (which has been properly hot tightend). I'm not sure what could be wrong now? My print detachted and on inspection there was a filament blob under the silicone sock, which leads me to believe there was a leak at the nozzle.
When cleaning the block after the first leak, I used a metal pick to clean up the threads where the nozzle and heatbreak screw into. Might I have damaged them in this way, causing a leak? Do I just stop bothering and order a new hotend?
