Beacon angle off…
So I have a major issue getting my V-core 4 to put down any first layer I would call consistent or even mediocre. For months, I have been troubleshooting everything I have read that could cause issues with the first layer. By a fluke, when I was taking measurements, I noticed the Beacon PCB was anything but straight.
It slopes due to the printed part is badly printed, and the inserts are not put in straight.
The distance from the nozzle to the bed in the photo is 0.5mm.
The distance from the back of the beacon PCB to the plate is 3.2-3.4mm.
The distance from the front of the beacon PCB to the plate is 4.4-4.7mm.
After checking the beacon documentation, I learned the difference between beacon contact, where the nozzle physically touches the bed plate to collect data, and beacon proximity, which probes the bed about 2mm above the bed surface. The latter is the default setting for doing z-alignment of the bed on the V-core 4 if I have understood everything correctly.
Could this be the cause of all my issues?
What kind of problems could this cause? According to the beacon documentation i could find that the offset from the tip of the nozzle to the bottom of the plate should be c:a 2.6 to 3mm. V-core 4 standard at least according to their CAD file is 2.89mm.
All thoughts or information are welcome! Hopeing to be able to print something with this machine before I lose my mind....
Thank you!

Mine was angled as well because the plug pushed against the printed part when tightening the screws, I've put some small spacers in to fix that, working fine for me.
What size do you have an what's the exact first layer issue you are facing?
I'm not exactly sure if a non straight beacon can cause measurement errors, but I would guess it could be a cause of this issue.
The beacon has to be straight from what I've seen in other threads. Fix that first absolutely
I have the baby v-core 300 😄 Yeah using shims will still put it at an angle sins the part is to off, I have about 0.5mm clearance between the housing and connector. And there is no point in sanding it down then shim it, might as well just print new housing and install heat inserts straight! I am more and more convinced this even if it doesn’t solve all my problems it will at least let me cross that of the list of fault 🙂
Thank you! Will print new parts tomorrow and install everything this weekend!
