Longer lk5 pro with skr mini e3 v3 cant get the z motors to work

[sammyz845]

Basic Information:

Printer Model: longer lk5 pro

MCU / Printerboard:skr mini e3 v3
Host / SBC rasberry pi 4b
klippy.log

Fill out above information and in all cases attach your klippy.log file (use zip to compress it, if too big). Pasting your printer.cfg is not needed
Be sure to check our “Knowledge Base” Category first. Most relevant items, e.g. error messages, are covered there

Describe your issue:

first time posting here and first time klipper user I would like to get better prints and was recommended to try klipper i intalled the mcu set up my klipper config and bl touch as well as a direct drive extruder everything communicates x and y home just fine but my z wont move at all the bl touch works and responds like like it should iv looked over the file and i cant see where i went wrong i have dual z motors and there plugged in the correct spots on the board im sure its something im doing wrong any help would be apreciated maybe something i should be paying attention to iv searched all over for this someone told me that the z stop needs to be plugged in even if im using the bl touch so i plugged that in and still have the same result?

You were asked to provide your klippy.log - we can’t help you without that.

Along with that, you may want to provide a wiring diagram, especially in the area of the Z Axis stepper motors.

Thank you for your reply i will get the log and wiring diagram when i get home from work i do appreciate your help

[sammyz845]

just added the klippy log

The diagram is not quite what I was asking for. I am asking for the actual wire connections between the Z Axis motor(s - see below) and the BTT SKR Mini E3 V3.

Could you answer the following questions:

1. Again, could you provide a diagram showing how the wires are connected between your Z Axis steppers and the BTT SKR Mini E3 V3.
2. Could you list all the modifications that you have made to the printer. Your saying “dual z motors” but when I look at the Longer LK5 PRO sales page, it only has one Z Axis motor. You also have a BL Touch installed in the printer and that doesn’t seem to come with the printer.
3. Is that the full klippy.log? It looks like the start of it has been cut off. If it’s too big to drag onto the post then .zip it first - please do not edit your original post, put the full klippy.log into your reply so that it is obvious that it is a new version.
4. Could you provide your printer.cfg file in your reply (along with klippy.log) - it doesn’t look like you have a [include mainsail.cfg] statement in it and you are using your own PAUSE, CANCEL, etc. macros.

Having asked for all this, I took a look at your klippy.log and I think your problem is with your [stepper z] definition.

You currently have:

[stepper_z]
step_pin = PB0
dir_pin = !PC5
enable_pin = PB1
microsteps = 16
rotation_distance = 8
endstop_pin = probe:z_virtual_endstop
position_max = 400
position_min = -3

With the enable_pin statement not being marked as inverted with the “!” character.

Before doing anything else change the [stepper z] statement to:

[stepper_z]
step_pin = PB0
dir_pin = !PC5
enable_pin = !PB1 # <== Note the "!" before "PB1"
microsteps = 16
rotation_distance = 8
endstop_pin = probe:z_virtual_endstop
position_max = 400
position_min = -3

thank you so much !!! making that change got the z motors working and my bl touch was able to respond to the plate now i need to just figure out how to get the bed mesh setting set and the extruder working
the upgrades i have done so far is an
ender direct drive
dual z motors
micro swiss hot end
BTT filiment sensor
and a mgnetic pei sheet
rasberry pi 4b with touch screen and klipper screen installed
running fluid for klipper

This is whole new territory for me and im super thank full for your help
