very inconsistent first layers on VC4

Since building my printer, I have had very inconsistent first layers, I did all the calibration and when it works, it works. But about 50% of the time it does not. I think I’ve narrowed it down to an issue with the Beacon contact and possibly some filament always being on the tip of the nozzle so the printer thinks it’s hit the bed before it actually has. I’ve attached two photos of the same G code printed, consecutively with zero changes made in between to show the difference. Is there a way to add a sequence to the start print macro where the printer will wipe the nozzle or maybe increase the temperature of the probing sequence so that the filament melts and does not trigger the beacon contact?
