Hi
I am a newbie to the forum and 3d Printing.
I have just bought an A20T and a BL 3d touch probe, after going through the forum I managed to update Hex firmware using Cura.
so i am now running
Marlin: 1.1.8
HW Ver: GT2560 V4.1
FW Ver: 2.3
I have manually leveled the bed and installed BL Touch, however the video on Geeetech is different to what i am seeing, but i can understand the gist of it.
my problem is when i go to setup gap, my extruder is about 2.55mm from bed and Z offset is -.50.
i have tried using various figures for offset and everytime i try bed level my touch checks middle of bed, then goes to front corner.
The extruder lowers, but the probe does not extend again and it hits my bed.
I can reset touch and it follows the deploy/stow commands on LCD also
M280 P0 S10 ; pushes the pin down
M280 P0 S90 ; pulls the pin up
continously whilst i am entering the commands
but then on next use it does not deploy again.
i dont know how to get into firmware to change anything but i have managed with the G code commands.
please help i have had my printer a week now and still setting up, not even loaded filament yet and it looks like it may take flying lessons very soon.
Thank you
Neil
