[Closed - Upgrade 3.0 to 3.1] Lead screw too short by 20mm
Hello everyone, I purchased from ratrig the V-Core 3.0 300mm in 2021. I just finished the upgrade to the 3.1 version with the supplied ratrig kit. I noticed that my leadscrews are 360 mm instead of 380 mm like indicated in the 3.1 BOM. As a result I can't level my bed without the bed arm colliding with the leadscrew top guides. Maybe I am missing something in the assembly.
I can't find the 3.0 BOM if they state that they provided 360 mm or 380 mm leadscrews back in 2021. If someone that made the upgrade could check their leadscrews length I would greatly appreciate the support. Thank you.

not sure but have you checked maybe the z motor mount/assembly is different? another coupler/bearing for z leadscrew support that will actually increase the height of the leadscrew

Yes I thought about that and I measured the lead screw. 20mm is missing, I got 360 mm lead screws instead of 380mm. I contacted ratrig support.
