you are missing S2 ; probe near a leadscrew and calibrate 2 motors
in the last command

Added the s2. Still have the extruder setup trying to go past the endstop to probe.

Veti

can you post the messages from the console.

nightmare90gt

Error: Probe points P0 to P1 must be in clockwise order starting near minimum X and Y

left leadscrew probed at Y132.5 and X 282.2
right leadscrew probed at Y 132.5 and x -27.8

right leadscrew probed at Y 132.5 and x -27.8

adjust the probing points with your offset in mind

if you want to probe at x0 that would mean the nozzle has to move to -30.814, which it obviously cant
so choose probing points that are reachable.

if you then still get the error message about the order, swap the probing points.

nightmare90gt

@Veti I have it in bed g its suppose to probe at 3 for x. Could it be adding the offset of the probe to were it probes?

Veti

@Veti said in Ender 5 Plus with dual z calibration:

X3 Y150

to probe this point, your nozzle would be at x-27 z 133

the console even tells you that

right leadscrew probed at Y 132.5 and x -27.8

nightmare90gt

@Veti right so its adding the offset of the probe so I would need to set the probe point at x30 for the probe to be at x0

I would need to set the probe point at x30 for the probe to be at x0

for the nozzle to be at x0 yes

@nightmare90gt

Are you using the default hotend and bltouch locations ?
Because G31 P500 X30.814 Y17.505 Z-0.425 would put your bltouch on the right of the nozzle / hotend .

nightmare90gt

No i have a bmg-x2-m setup.

nightmare90gt

I also have a quick question related to problems I am having. What would cause a motor to stutter? When I home the x axis the whole gantry studders. It is a corexy setup so I am new to this.

Veti

@nightmare90gt
the ender 5 is not a corexy printer

nightmare90gt

mine is I have install a Kay3d corexy kit. the stuttering only seems to happen when you homeall but not if you home them individually.

Veti

can you post a video of it? showing both stuttering and not stuttering

i dont see anything wrong in the config.

the difference between the homeall and home x / y is:

home x and y use both motors.

the initial move in homeall uses just 1 motor (corexy diagonal moves is just one motor turning)

so things to check. is the other motor actually still, or does it move.

i think its something mechanical
try reducing the speed and see what happens during the move.
so change
G1 H1 X-325 Y-355 F1800 ; move quickly to X or Y endstop and stop there (first pass)
to
G1 H1 X-325 Y-355 F180 ; move quickly to X or Y endstop and stop there (first pass)
