Fixed my temp/heater issue . . .
Now I'm having a heck of a time trying to get my delta calibrated. Its a modified rostock max. I've torn it down and rebuilt it a dozen times to see if maybe i got something wrong mechanically.
I use FSRs to probe.
I've added PEI to my boro glass plate.
So here's my process. . .
Added in my config.g
M558 P4 X0 Y0 Z0 H3 F50 T6000 to probe (super slow)
M557 R135 S15 enables grid probing map
Added to Bed.g
bed.g file for RepRapFirmware, generated by Escher3D calculator
; 16 points, 6 factors, probing radius: 120, probe offset (0, 0)
G30 P0 X0.00 Y120.00 Z-99999 H0
G30 P1 X77.13 Y91.93 Z-99999 H0
G30 P2 X118.18 Y20.84 Z-99999 H0
G30 P3 X103.92 Y-60.00 Z-99999 H0
G30 P4 X41.04 Y-112.76 Z-99999 H0
G30 P5 X-41.04 Y-112.76 Z-99999 H0
G30 P6 X-103.92 Y-60.00 Z-99999 H0
G30 P7 X-118.18 Y20.84 Z-99999 H0
G30 P8 X-77.13 Y91.93 Z-99999 H0
G30 P9 X0.00 Y60.00 Z-99999 H0
G30 P10 X51.96 Y30.00 Z-99999 H0
G30 P11 X51.96 Y-30.00 Z-99999 H0
G30 P12 X0.00 Y-60.00 Z-99999 H0
G30 P13 X-51.96 Y-30.00 Z-99999 H0
G30 P14 X-51.96 Y30.00 Z-99999 H0
G30 P15 X0 Y0 Z-99999 S6
I will then probe and run the M665 and M666\.
enter in the variables in the config g and do it again until they converge. . . (i do this both hot and cold and not much difference)
here are some runs:
Endstop adjustments X-0.08 Y-0.05 Z0.13, tilt X0.00% Y0.00%
Diagonal 269.000, delta radius 129.521, homed height 431.005, bed radius 125.0, X -0.107°, Y 0.350°, Z 0.000°
Endstop adjustments X-0.07 Y-0.08 Z0.15, tilt X0.00% Y0.00%
Diagonal 269.000, delta radius 129.471, homed height 431.006, bed radius 125.0, X -0.172°, Y 0.352°, Z 0.000°
Endstop adjustments X-0.08 Y-0.06 Z0.14, tilt X0.00% Y0.00%
Diagonal 269.000, delta radius 129.558, homed height 431.013, bed radius 125.0, X -0.145°, Y 0.367°, Z 0.000°
Endstop adjustments X-0.05 Y-0.07 Z0.13, tilt X0.00% Y0.00%
Diagonal 269.000, delta radius 129.538, homed height 431.019, bed radius 125.0, X -0.080°, Y 0.363°, Z 0.000°
After I feel my readings are just going up and down, I go through bed compensation.
added to config.g
G29 S1 ; load bed leveling compensation
Run G32 without homing
A nice graph pops up with this.
So here's the problem:
What in the world is going on. Its like I never calibrated . . .
I can't be that far off the mark.
A couple of things. I do adjust my G31 command in my config.g
G31 X0 Y0 Z0.1 P500
I vary Z in 0.025 increments hoping to find a sweet spot. The issue is it doesn't matter because its clear I'm high in one spot and low in another. Isn't bed compensation supposed to fix this?
