Ha... I thought you said working versions of Marlin!
I'm using RC6 4/20/16 ... I had configured auto bed leveling on that but it doesn't DO anything.
I switched that to Mesh Bed Leveling with a Z Stop. (You have to level it with a piece of paper.
It ignores the Z-probe for G29 S1 or S2.) And somehow M420 S1 has to actually enable it???
It doesn't really 'say' in the code. (firmware. One is supposed to know.)
BUT, RC6 lowers the probe and smashes it into the bed (ignoring the z-probe) with a G28 X Y:G28 Z
---
Mesh bed level really doesn't know where the probe is. It assumes one levels with a piece of paper.
But it now uses the probe (but doesn't know if actually isn't even over the bed, how high, etc. Nightmare.)
Auto Bed Level knows where that probe REALLY is. But, takes the nozzle and grinds it into the bed (because
it actually isn't doing any Z adjustment...)
--
However, I went and fixed the firmware. But, my X axis NEEDs to be level or all heck breaks loose. So I shove
a shim to try and get the nozzles level... They are perfect right now. I'm using MBL not ABL. I have a Z min stop,
a Z probe, min and max stops all around.

Huh. That's weird.
Here's the Configuration.h file I'm using with RC3 on my 12".
https://github.com/clough42/Marlin/b...onfiguration.h
If you use this, check the thermistor settings. I'm running an industrial silicone heater and some other odd stuff.
And this is my start GCODE:
Code:M80 ; power on M42 P5 S255 ; light on M190 S[first_layer_bed_temperature] ; wait for bed to heat up M104 S[first_layer_temperature_0] T0 ; start heating T0 M104 S[first_layer_temperature_1] T1 ; start heating T1 G1 Z15 F120 ; lift nozzle G28 ; home X and Y axes G29 ; auto bed level G1 X313 Y12 F15000 ; move to side G1 Z0 ; Level for wipe M109 S[first_layer_temperature_0] T0 ; wait for heat M109 S[first_layer_temperature_1] T1 ; wait for heat G90 ; absolute T0 ; extruder 0 G92 E0 G1 E12 F50 ; extrude G1 X0 F15000 ; wipe G1 Y15 ; slightly forward so other wipe won't overlap T1 ; extruder 1 G92 E0 ; reset extrude G1 X0 E12 F50 ; extrude G1 X250 F15000 ; wipe
Please explain to me how to...
