Z axis home and moving issue

tecno

X120 Y120 Z120 or Z0 depening on setting in Homeall/HomeZ.

tecno

If I set homeall/homeZ to be Z0 in DWC and command G0 Z25 the bed is not moving as it should.

@tecno I think you drive numbering in config.g is wrong you have Z4 but should that be Z3?
M569 P0 S1 ; physical drive 0 goes forwards using default driver timings
M569 P1 S1 ; physical drive 1 goes forwards using default driver timings
M569 P2 S1 ; physical drive 2 goes forwards using default driver timings
M569 P3 S0 ; physical drive 3 goes backwards using default driver timings

@Rushmere3D

No, it is on purpose set to the last driver.

@tecno Drive 4 doesn't exist?

@Rushmere3D

Mini5+ has 5 drivers 0-1-2-3-4

Your max speed for Z is pretty high. Is it perhaps stalling when you're trying to move at over 40mm/s?

@tecno Did you use the config tool to create the config.g? Because if you did how did you select driver 4?

Where is driver 4 is up in your config.g I see P0-3 but you have 4 in the M584?

It's not listed so it would be using the default values for M569 P4

If it's homing the driver is working.

@tecno
Your Z-endstop is set to low end...

M574 Z1 S1 P"io2.in"

Change that to Z2

Edit:
Forget about it.
I mixed it up with the configuration of a bed slinger....

@tecno Where is the endstop located? Z min at the nozzle?

Rushmere3D

@Phaedrux Yes a Voron Z endstop is at Z0 the top of Z travel.

No go either

If the endstop is at zmin by the nozzle then your endstop config must be M574 Z1 S1 P"io2.in" and your homing move for Z must be G1 H1 Z-150 and I would remove the G92 Z120 entirely unless you need to set a small offset to indicate exactly how far off the bed the nozzle is when the endstop triggers.

You should also define M569 P3 S0 or S1 and make sure the motor rotation is set correctly. But if -z movement makes the bed rise to the nozzle, then it is correct.

M569 makes no difference in moves, homeing Z moves up to nozzle and from there no -Z works

tecno

G91 ; relative positioning
G1 H2 Z-5 F6000 - moves bed down

Phaedrux

H2 will force a move regardless of where it thinks the Z position is on the axis.

If Z-5 moves the bed down, you have either not followed the settings from my post, or the M569 for the Z axis needs to change the direction of rotation.

Perhaps post your current config.g and homeall.g so we can see what it is now.

homez.g homeall.g config.g

You still need to add M569 P4 for the Z axis since you're using driver 4

G1 H1 Z125 F360 ; move Z up stopping at the endstop

Your homing move must be negative if the endstop is at zmin.

Positive Z moves should move the bed down away from the nozzle. If that homing move is going to the endstop, you need to change the direction of rotation for driver 4.
