Not Homing correctly At all. and nozzle issues

Can you post a photo of the hotend?
Is there something in direct physical contact with the heat block?
Is the fan blowing directly on the block without a silicone sock?
Perhaps the Ender 5 Plus is using a different thermistor than other creality hotends and your thermistor values are completely off.

@Phaedrux hello can you please help me solve this issue so my ender 5 plus has 2 Zmotors and when I run G32 it doesn't compensate or level the bed very well it still off from corner to corner so I found that I need to set an independent Zmotors to get auto bed leveling up and running I connected first Z motor LeftSide to Z-drive and the second one right side to E1 I spent days reading the duet form but it's not working for me or I have no clue what I'm doing, if you please point me in the right direction that would be highly appreciated

here's my config.g file

; Drives

M569 P2 S0 ; physical drive 2 goes backwards
M569 P3 S0 ; physical drive 3 goes backwards
M584 X0 Y1 Z2 E3 ; set drive mapping

You're going to need to define drive 4 for use as a second Z axis in config.g and change your bed.g to do the probing for the leveling adjustment.

; Drives
M569 P0 S1 ; physical drive 0 goes forwards (X axis)
M569 P1 S1 ; physical drive 1 goes forwards (Y axis)
M569 P2 S0 ; physical drive 2 goes backwards (Z1 axis)

M584 X0 Y1 Z2:4 E3 ; set drive mapping
M671 X-20:220 Y0:0 S0.5 ; leadscrews at left (connected to Z) and right (connected to E1) of X axis

For the points in M671 you need to find the coordinates of your own bed to measure, you can't just use the example points.

You will connect one Z motor to the Z1 (drive 2), put the jumpers back in the second port. Then connect the other Z motor to the E1 (drive 4)

For bed.g you'll also have to find the points to probe with G30

G28 ; home
M401 ; deploy Z probe (omit if using bltouch)
G30 P0 X20 Y100 Z-99999 ; probe near a leadscrew, half way along Y axis
G30 P1 X180 Y100 Z-99999 S2 ; probe near a leadscrew and calibrate 2 motors
M402 ; retract probe (omit if using bltouch)

The G30 P1 will likely be further to the right on your larger bed so adjust the CX position accordingly.

moe.adams9093 · 2 May 2020, 05:16

Thank you very much for all your help. I will make these adjustments tomorrow, but how can I find points in M671 coordinates of my own bed measuring, is their sort of documentation can explain how to find the coordinate positions of my bed. thank you again

Phaedrux · 2 May 2020, 05:29

You just need to choose a point close to the lead screw but still on the bed and both need to be in line on the Y axis.

THANK YOU. it worked and I found my correct bed coordinate points. do I have to change any config for my BLtouch current settings are

Phaedrux · 5 Mar 2020, 17:10

The dive height is a little low. It should be at least a mm more than the trigger height. Try M558 H3

Also change G31 P500 to G31 P25

Have you calibrated our probe and measured the offsets yet?

moe.adams9093 · 4 May 2020, 09:45

so I have adjusted all the settings accordingly here's a photo of the hight map so I don't if that's ok or it should be 0 all the way I tried to print a file 340 x 340 and it looks like it's not adjusting probably. here's my updated file config.g

I don't know if i have to enable some settings to run hight map while it prints maybe from slicer or from DWC. thank you for all your help

moe.adams9093 · 4 May 2020, 09:52

when I run G32 here's the message I get
does that meat its successfully calibrated.

moe.adams9093 · 4 May 2020, 10:03

also here's the message when I run G29.
please let me know if that looks good sorry I know I have been asking you a lot. Thanks again

Phaedrux · 4 May 2020, 16:27

Print a test file like this one with mesh enabled and again disabled. You should be able to tell if it's being applied correctly.

bedlevel_nozzle_0.4_200x200-0.3-0.8.stl

moe.adams9093 · 6 May 2020, 07:52

Yes I did what you told me and it looks like its not working properly. Any other suggestions would be helpful. Thanks

@moe-adams9093 What slicer are you using? Please post your start GCode from your slicer.

G31 P25 X0 Y0 Z1.758

You need to measure your X and Y probe offset otherwise the corrections will be off in X Y position.

https://duet3d.dozuki.com/Wiki/Test_and_calibrate_the_Z_probe?revisionid=HEAD#Section_Measuring_Probe_X_Y_Offset

The heightmap itself looks ok. After measuring the offset redo the G29 and reprint the test file to see if it's behaving better.

moe.adams9093 · 9 May 2020, 06:08

Thank you for the additional information so my x offset is 44mm and the y offset is -5mm but when I try to run mesh compensation its starting from 44 to 285 and my actual build volume is 350 x 350 so please correct me on that one am I loosing that left over space since it only probing from 44 to 285. Also when I checked my old configuration from the original bord it says offest x0 y0 z1.78 so I don't if that does matter or not. Please let me know thank you
