### Basic Information: Printer Model: Ender 6 MCU / Printerboard:Manta M8P `klippy.log` ### Describe your issue: M8P V1.1 mainboard and Biqu H2 extruder I have given up on a weeks worth of trying to get it working and started again I downloaded latest CB1 image from s://github.com/bigtreetech/CB1/releases dated March 6th flashed on a new SD card Changed Wifi SSID and Password to mine Booted Manta Mm8P Logged in with SSH compiled the firmware and flashed it as per the instructions Had tp put the board in DFU mode to flash as it would not install from SD card but it worked and using ls /dev/serial/by-id/ gives me my device ID I then loaded the webpage using the IP address of the Manta M8P Updated all modules using the Update Manager Loaded my Ender 6 printer..cfg that has a Biqu H2 extruder on Motor 5 made sure the printer.cfg uses all 3 endstops and the pins are correct I have made 4 new stepper cables by referencing the pinout in the Manta M8P pins and physically checking each stepper with a multimeter to make certain I was wiring it correct I have checked the Jumpers for stepper power, TMC2209, Fan Voltage, Diag has no jumpers Endstops are: X is on the right hand side of the machine looking at it Y is at the back right looking at it The only other difference is I’ve got 15mm less travel in both axis due to linear rails being fitted. When I try and home any axis X moves the carriage forward towards the front of the machine Y moves the carriage to the right of the machine Nothing I do changes this, I have even tried swapping the X and Y stepper cables but that just made it worse I have tried everything possible to fix this and using the Configuration checks in the Klipper documentation doesn’t help M112 works All of the printer axes can manually move freely Verified endstops STEPPER\_BUZZ STEPPER=stepper\_x moves the carriage moves back and left at the same time STEPPER\_BUZZ STEPPER=stepper\_y moves the carriage moves back and right at the same time I have checked the belts using the service tutorial video Can anyone look at my config and tell me if they can see what’s wrong?

Hello @lew247 ! > [@lew247](#): > > STEPPER\_BUZZ STEPPER=stepper\_x moves the carriage moves back and left at the same time > STEPPER\_BUZZ STEPPER=stepper\_y moves the carriage moves back and right at the same time It is a CoreXY pinter. Both steppers have to move to move the printhead in one direction: > **[CoreXY Kinematics - 3D Distributed](https://3ddistributed.com/corexy-3d-printer/corexy-kinematics/)** > > The corexy kinematics mechanical arrangement includes a unique motor movement where the X or Y motor move together or opposite of each other to move the Have you tried to invert the direction of the X and Y steppers? ---

The attached link will show you how to make the printer move in the correct direction on a corexy. You might need to swap the X and Y (really should be called A and B), and you might need to invert the direction on one or both motors. > **[Initial Startup](https://docs.vorondesign.com/build/startup/#motor-configuration-guides)** > > Voron Official and Community Documentation ---

I’ve actually done all that and tried swapping the X and Y as per my post details ---

I assume also the motor direction. ---

Yes as well as swapping the cables I have tried reversing both motors one at a time and it still does the same thing ---

I’ve been through this a couple of times on my CoreXY printers and it’s frustrating. What I now do is first identify my variables with labels, make up a table of the various wiring permutations, work through the table entries and record what I see for each condition. On my Manta, I use the Motor1, Motor2 Stepper Drivers for X & Y, Cable A for the Stepper on the Left Side and Cable B for the Stepper on the Right Side, Direction1 and Direction2 pins for the DIR values in my printer.cfg so it looks something like: ```auto Cable A Cable B Direction1 Direction2 Motor1 Motor2 PB4 PF11 Motor1 Motor2 PB4 !PF11 Motor1 Motor2 !PB4 !PF11 Motor1 Motor2 !PB4 PF11 Motor2 Motor1 !PB4 PF11 Motor2 Motor1 !PB4 !PF11 Motor2 Motor1 PB4 !PF11 Motor2 Motor1 PB4 PF11 ``` Note that I use a Grey Code approach so that I’m only changing one variable at a time. Let us know if this helps. ---

Thank you so much, that finally worked I had to have Motor2 Motor1 !PB4 !PF11 and now it works in the right directions ---
