Hello I am new here and need some help.

Printer Model

voron 2.4

Extruder Type

Other

Cooling Type

Afterburner

Hello, I did build a voron 2.4 but when I started it up the hot end starts heating and goes on till it hit the max and then it turns off.
another problem is the homing the x as goes well but the y as goes forwards so it never goes go to the end stop in the back.
And if I try to move the z as it only goes down.
What did I do wrong?

Revers the direction of Y by adding a ! to the PIN.

I think you need to give more informaiton about the hotend heating up.
Does this just happen when the printer is turned on? Max is set to 270c.?
When it hits 270 does the machine turn off or does the heater shut down or?

It is as you say.
If i turn on the printer it start heating immediately till it get to the maxtemp and then it gifs a mcu error and shutdown.
I have to disconnect the wires to turn the hot end off.
The printer came with a canbus.

Have you loaded klipper and flashed the firmware?
there is a note in the Voron Documentation to disconnect HE0 or 1 until the MCU is flashed.

"
WARNING: Do not leave HE0 or HE1 connected.
There have been reports of Octopus boards coming preloaded with a firmware that turns on all heaters and fans as soon as you power up the board. As a result, we recommend leaving the heaters disconnected until after loading the klipper firmware"

It is preinstalled I didn't do anything to the software.
But the serial is OK I checked it.
So it is flashed.
