<solved>M557 grid parameters not being followed.

RyanP

I have just switched both my CR10S and my Ender 5 Plus over to independent steppers using E1. I have gotten both set up, and able to properly do the G32 command. Now I want to proceed to complete mesh bed compensation. It works perfectly on my CR10S. The M557 command is correctly applied

CR10S:

; Z-Probe
M307 H3 A-1 C-1 D-1                       ; disable heater on PWM channel 3 for BLTouch
M558 P9 H1.5 F180 T24000 A10 S0.003 B1 R0.5   ; set Z probe type to bltouch and the dive height + speeds
G31 P500 X-41.8 Y-24 Z0.73	           ; set Z probe trigger value, offset and trigger height
M557 X15:255 S60 Y10:280 S90            ; define mesh grid

So when I got through the (almost) exact same setup on my Ender 5 PLus, the system (DWC) ignores the M557 parameters. It worked perfectly yesterday. But since I switched to separate z-steppers, it is not following the grid I have requested. Im requesting a starting grid point of X45 Y30. This accommodates both offsets from the corner origin.

But regardless of what is in my config.g, nor if I input that exact into into the drop down menu in DWC, nor if I send the exact line of gcode. The first point is X3.2 Y6.

Ender 5 PLus:

; Z-Probe
M307 H3 A-1 C-1 D-1                       ; disable heater on PWM channel 3 for BLTouch
M558 P9 H1.5 F180 T24000 A10 S0.003 B1 R0.5   ; set Z probe type to bltouch and the dive height + speeds
G31 P500 X41.8 Y24 Z1.036	           ; set Z probe trigger value, offset and trigger height
M557 X45:350 S61 Y30:350 S64             ; define mesh grid

Here is the total config G for my Ender 5 Plus:

BTW, I just updated to firmware 2.05.1 on both machines.

What am I missing?

@RyanP said in M557 grid parameters not being followed.:

G31 P500 X-41.8 Y-24

G31 P500 X41.8 Y24

I don't know if this is related or not, but you have the same numbers but the signs are reversed. Is the probe actually placed inexactly the same distance just reversed?

@RyanP said in M557 grid parameters not being followed.:

The first point is X3.2 Y6.

It also seems telling that your first point is exactly the distance of your offset minus the X Y minima for the grid.

You say you're running G32, what do you have in the bed.g?

I have the same offsets but reversed because I am using the same mount for both printers, and the BL Touch is in the exact position. Only difference is where the 0,0 origin is. On the CR10S it is on the front left, and the Ender 5 Plus it is on the back right. thats why they are reversed. The probes relation to the nozzle is literally flipped.

As for my bed.g

M561 				; clear any bed transform
G29 S2				; Clear bed height map
; Probe 2-points
M401 				; Deploy probe - deployprobe.g
G30 P0 X45 Y175 Z-9999 		; Center Left
G30 P1 X345 Y175 Z-9999 S2 	; Center Right
M402 				; Retract Probe - retractprobe.g

That makes sense. I'll have to take a closer look tomorrow.

Dumb oversight. I have been using the same parameters for the probe offset, but completely ignored the fact that I just changed this printer from a Microswiss hotend to and E3D Volcano. Y offset was not correct.
