Description

Good afternoon, everyone!
Today I became a happy owner of Microprobe v2.
I have encountered an incredibly terrible problem. On my MKS Robin Nano V3.2 board.

The microprobe stylus does not always go in after building the map before printing. Therefore, the stylus itself moves around on the table.

I also noticed that the PROBE_UP command does not work, but a faint click is heard (the stylus remains at the bottom). Sometimes everything works fine.
