1. I manually prelevelled the bed using your credit card instructions.
2. I then did an Autohome
2. Set the bed temperature to 60C as that's my normal working temperature.
3. Waited until it hit 60C
4. Then went to Prepare -> Bed Leveling -> Level bed.
5. The first row across went correctly (AFAIK).
6. The second layer then just gets higher and higher until its almost at the rop of the Z axis frame.
I did try to create a video and accidently pressed the record button twice so it didn;t record.
Went back again to re-record the video and it now works. The bed levelling has gone across without constantly going up. This is very confusing.
So lets try a third attempt with video, which has now also not worked. my iPhone stops recording after 90 secs <grrrr>
This time it's failed again. It did the first rows and then the second row just keeps tracking up the Z axix and never getting lower. It's almost as if the Z value is negated after the first row of checking.
I'm going to look at the code but this makes no sense to me at all. It has worked once and failed twice.
I've gone back to the source…
I've gone back to the source code for V1.1.9.1 and downloaded it.
Opened and made three changes to
#define X_PROBE_OFFSET_FROM_EXTRUDER -44 // X offset: -left +right [of the nozzle] Customized DBP
#define Y_PROBE_OFFSET_FROM_EXTRUDER -8 // Y offset: -front +behind [the nozzle] Customized DBP
#define Z_PROBE_OFFSET_FROM_EXTRUDER 0 // Z offset: -below +above [the nozzle] Customized DBP
for the BLtouch bracket.
Compiled it and loaded it on the printer.
Octoprint is removed from system.
