corexy printer setup
how to change sequence homing x,y
i am using M3D promega and i need to change sequence first y axis home after x axis
manual working fine by hand trigger switch x limit and y limit

Error: Height map file heightmap.csv not found

@patel

you need to either replace G29 S1 with G29
or do a probing manually with G29 once

this file copy from M3D promega

; homeall.g
; called to home all axes
;

; Front left corner is (0,0)

; ============ HOME X & HOME Y ==============

M98 Phomex.g ; Run the homex.g file, also homes the Y axis

; ============ HOME Z ==============

M98 Phomez.g ; Run the homez.g file

this is homex.g file
; homex.g
; called to home the X axis
; October 4, 2018

; same as homey.g because of coreXY
; Front left corner is (0,0)

; ============= PRE-HOMING =====================

; Ignore Machine boundaries
M564 H0 S0

; Turn off bed leveling during homing
G29 S2 ; Does the same as M561!

; Switch to Origin Tool
T0

; Relative positioning
G91

; Provide Z height clearance
G1 Z10 F750 S1

; ================== HOME Y ============================

; Rapid Y until limit switch triggers
G0 Y450 F1500 S1

; Back off to release limit switch
G0 Y-6 F1500

; Slow advance to trigger limit switch
G0 Y10 F120 S1

; Set this location as Y = 384mm
G92 Y384

; Move the gantry slightly away from back of printer, to allow travel past the bolt mounting the gantry bracket
G0 Y-5 F1200

; ============= HOME X ====================

; Rapid X until limit switch triggers
G0 X450 F1500 S1

; Back off to release limit switch
G0 X-6 F1500

; Slow advance to trigger limit switch
G0 X10 F120 S1

; Set this location as X = 380mm
G92 X380

; Move away from the limit switch, to prevent damage to it upon next move
G0 X-5 F1500

; ============ Post-Homing ==============

; Revert to absolute coordinates
G90

; Re-enable mesh leveling
G29 S1

M98 Pmachine_axisdimension.g ; Set Axes Limits

; Stop movement across limits, enable boundaries, homing requirement
M564 H1 S1

G29 S1

because you still have the same command in your homing file

patel

@veti
need to delete or just change G29 only
can you enplane more detail

G29 S1

https://duet3d.dozuki.com/Wiki/Gcode#Section_G29_Mesh_bed_probe

S0 (default if no S parameter) Probe the bed, save the height map in a file on the SD card, and activate bed compensation. The height map is stored in file is

S1 Load the height map from file and activate bed compensation. The default filename is as for S0 but a different filename an be specified using the P parameter.

I need to fix first homing problem if you have idea.

M569 P1 S0 ; Drive 1 goes forwards, CoreXY_1

change S1 to S0 know homing process fix
