Solved Issues with M206, homing, leveling and probing
-
After finishing building my new printer I starte to tune dimensions and macros of my old printer to the new.
Both are coreXY but the dimensions limits changed a little.
For a start, the X0 Y0 is offset -60mm for Y. So I used M206 Y-60 to set this offset.
There is where my problems start!
If I manually, gcode by gcode, apply my home all macro then it works flawlessly but I execute a G28 a G0 command to send the tool to X132 Y156 send it to X132 Y96!!!!! But only when executed from the G28 or home all DWC button. If I do line per line all goes well.
The same happens for the G32, that I use with dual lead screws to correct the tilt of the bed. And so with the mesh commands of G29 - if I execute from the console the go to the correct XY coordinates. If I command from macros or system macros then they consider Y-60 as Y0 and the too goes out of the bed...
What am I doing wrong?
Firmware: 2.02RC3
My config.g concerned part:
; Axis Limits
M206 Y-60
M208 X0 Y0 Z0 S1 ; Set axis minima
M208 X294 Y330 Z270 S0 ; Set axis maxima (needed to set the maxima as +60!!!!! why?? My real max is 270mm!!!!)My homeall.g
; homeall.g
; called to home all axes
;
; Home XY for Z homing
;
G91 ; relative positioning
G1 Z5 F200 S2 ; lift head relative to current position
M400 ; make sure everything has stopped before we make changes
M913 X50 Y50 ; set X Y motors to 50% of their normal current for homing
M98 P"0:/sys/m_set_low_speeds.g" ; set lower Z speeds and accelerations
; Home XY for Z homing
;
;==============Home X====================
;
G1 S1 X-305 Y-335 F4800 ; move quickly diagonally to hit X or Y
M400
G1 X5 Y5 F1000 ; go back a few mm
G1 S1 X-305 F4800 ; move quickly to X axis
G1 X5 F1000 ; go back a few mm;==============Home Y====================
;
M400
G1 S1 Y-335 F4800 ; move quickly to X axis endstop and stop there (first pass)
G1 Y5 F1000 ; go back a few mm
;==============Home Z====================
;
M400
G90 ; absolute positioning
G0 X132 Y156 F4000 ; move to center of bed; Probe the bed
;
M558 A1 F350 ; Set single probing at faster feed rate
G30 ; Do a single probe to home our Z axis
M558 A10 F100 ; Set tripple probing at slower feed rate
G30 ; Probe again to get a more accurate positionM400 ; make sure everything has stopped before we make changes
M98 P"0:/sys/m_set_normal_speeds.g" ; set normal Z speeds and accelerations
M913 X100 Y100 ; set X Y motors to 100% of their normal current -
When you say the offset is -60mm for Y, do you mean that the Y homing switch triggers at Y=-60mm? If so then you should change the first M208 command to:
M208 X0 Y-60 Z0 S1 ; Set axis minima
and not use M206 at all. See https://duet3d.dozuki.com/Wiki/Centering_the_bed_or_setting_the_bed_origin.

Hello,
Greetings from YD.My problem is related to Delta homing.
Whenever I try to home X, Y and Z axes, all the axes go 5 mm up and stop. I have tried all the possibilities that came to my mind. But all failed.
- Changed stepper motor with higher current rating and holding torque
- Tried all the possibilities with GCode and Mcode.
So I hereby seek expert advice.
My Config. g file is as follows:

Further my X and Y axes work perfectly fine as in for X+10 Y + 10, they both go up by 10 mm but for Z+5. Z axis comes down 5 mm. Code for this as follows:
M569 P0 S0 ; Drive 0 goes backwards
M569 P1 S0 ; Drive 1 goes backwards
M569 P2 S0 ; Drive 2 goes backwardsOR
M569 P0 S1 ; Drive 0 goes forwards
M569 P1 S1 ; Drive 1 goes forwards
M569 P2 S1 ; Drive 2 goes forwardsIn either case, the same problem was observed.
I tried changing the polarities only for Z. When i changed the polarities for Z, it was observed that during homing movement, X and Y went up but Z went down.
Further I tried with Duet3D code that came with DUET wifi board in an SD card. WIth that also, the delta homing is not happening.
So i am hereby messed up totally with Delta configuration, but my CoreXY is working nicely (at least printing).
Kindly provide your valuable help for Delta printer configuration.

@yd14 You should probably start a new thread for your problem rather than posting in a thread that is already marked as solved.
