Sorry to spam the board, but I’m really stuck. I’m using Drunken Octopus R53 on a TAZ 6 with BLtouch and Archim2 and Dual v3.1 extruder.
Here is what I can’t wrap my head around:
My Z probe offsets are:
X = 6.5 (centered between the two nozzles)
Y = 33 (behind the nozzles)
the default Z offset is -2.35.
If I use my actual X and Y probe offsets, the printer head crashes (or complains that Z probe is past the bed) because the X axis moves probably starting from the -26.1 start point (Does PROBING_MARGIN = 35 effect this?)
So, I’ve been fudging them and making the X offset = 16, which just barely hits the bed. Now as for the Z offset: the default in the firmware is -2.35. I home the printer with G28, and the print head moves up to 33.35. If I Move the print head down towards the bed at this point, the nozzle hits the bed at about Z = 5. Meaning, I think, that my Z offset it 2.7ish. But I’m pretty sure it’s supposed to be negative.
If I set the Z probe offset to 2.7 everything works as it should. And I can physically measure the end of the stowed BLtouch sensor as about 2.7mm higher than the nozzle. What am I getting backwards?
I ask this in the context of G29 P1 reporting a “probing failed” error and thinking it might be related
…It just repeatedly probes the same bed location for all 25 points.
Please help. I’ve been doing the same procedure for hours.
Here’s a summary of my config settings:
