Hello, I Have been upgrading an Anet A8.
I am having Three basic problems with my build that I just can't quite figure out; All Three problems seem to stem from the same origin, I would truly appreciate any ideas on how to trouble shoot theses Problems. Thank you in advance
I have Upgraded the control electronics to the new BIGTREETECH SKR_2 With the new 429 chip set. ( Absolutely love how quiet it makes the machine) I Have Compiled Marlin 2.0.9.3 to drive it. (Umpteen times so far!)
It does compile well, but for the life of me, I can't figure out what I keep missing in the firmware settings.
My first problem is with homing, it will not home at the center of the Bed. The BL Touch sensor contacts the bed at the center of the X axis, and it contacts 1/2 way between center of the bed and the Neg Y edge of the Bed.
My Marlin Settings are:
#define Z_SAFE_HOMING
#if ENABLED(Z_SAFE_HOMING)
#define Z_SAFE_HOMING_X_POINT X_CENTER // X point for Z homing
#define Z_SAFE_HOMING_Y_POINT Y_CENTER // Y point for Z homing
#endif
#define BED_CENTER_AT_110_110 // ORIGINALLY AT _0_0 (bed = 220 x 220)
* +-- BACK ---+
* | [+] |
* L | 1 | R <-- Example "1" (right+, back+)
* E | 2 | I <-- Example "2" ( left-, back+)
* F | [-] N [+] | G <-- Nozzle
* T | 3 | H <-- Example "3" (right+, front-)
* | 4 | T <-- Example "4" ( left-, front-)
* | [-] |
* O-- FRONT --+
#define NOZZLE_TO_PROBE_OFFSET { -27, -42, -3 } {these Values were measured with calipers} Why is the X axis offset being adjusted for by Marlin, But not the Y axis offset?
B) Auto leveling, seems to fall part way on the bed and part way off. It will not measure Positive Y (forward) of the center of the Bed, It fails trying to measure air.
C) the BL Touch sensor needs to be reset every time a G34 command is issued, but the Z axis leveling succeeds.
I have tried to Home, and Level the build plate from the Pronterface UI, From Gcode, and from My TFT. It responds in the same manner from all three sources.
I would really appreciate any help or information that you might have regarding how to further troubleshoot and correct these problems.
