Printer fails to probe a bed mesh when starting a print

Hey, I have a problem with my V-Minion, whenever it goes to do a bed mesh, it manages to probe some points, but suddenly plunges the nozzle into the bed (thank you for that spider coupling). The Mainsail console spits out this: 10:11 AM G91 G1 Z+25 F1500 10:11 AM G91 G1 Z+25 F1500 10:11 AM Extrude below minimum temp 10:11 AM Extrude below minimum temp See the 'min_extrude_temp' config option for details 10:11 AM Extrude below minimum temp 10:11 AM Extrude below minimum temp See the 'min_extrude_temp' config option for details 10:11 AM Extrude below minimum temp 10:11 AM Extrude below minimum temp See the 'min_extrude_temp' config option for details 10:11 AM Extrude below minimum temp 10:11 AM Extrude below minimum temp See the 'min_extrude_temp' config option for details 10:11 AM echo: Cleaning up... 10:11 AM No trigger on probe after full movement 10:11 AM No trigger on probe after full movement 10:11 AM No trigger on probe after full movement Any ideas what may cause this? The sample retract distance is 3mm

No trigger on probe after full movement
your probe isn't triggering. Since it seems to be sometimes I would guess bad wiring or connection

Then I have to open up the electronic enclosure again.. damn The probe seems to trigger reliably between 1.49 and 1.5mm, I don't think the wiring is the problem, though it doesnt hurt to check

it may in that spot but have you checked all the areas of your bed? Did you use good wire and not extend it using solder?

Should also note that I updated the system yesterday

that is a red herring

Got a successful bed mesh on the fourth try Red herring?

[from the practice of drawing a red herring across a trail to confuse hunting dogs] : something that distracts attention from the real issue
i.e. it has nothing to do with your probe problem

what probe are you using? you can try to increase the sample retract to check if the probe/wiring are working properly. Is always failing in the same area(within 1-2 probe points)?
