X min and z min problems

[x306xcptnkirk]

New board, steppers and when I autohome the x goes the correct way but the y and z turn the opposite way and go towards the max. How do I reverse the motor direction?

What is the board type? Can you reverse the connection of y and z motors? Is the endstop connected correctly?

[x306xcptnkirk]

Sorry about that it's a gt2560. Endstops are correct. When the x and y cables are switched. The x goes the correct way but the y still goes the opposite way

Switching y and z does yeild the correct direction though. What should I do to get the printer to work with them plugged into the correct sockets?

[zhangxueyou]

Oh, the motors can only be connected to gt2560 in one direction.
Maybe it's firmware issue, what is your printer type? Let me send you a correct firmware.

It is a i3c. How would I upload the firmware as well?

[x306xcptnkirk]

please send the firmware as well as instructions on how to burn the firmware to the gt2560 i3c. Do you email the firmware or post it here? Also should i use arduino 1.0.1 or 1.6.5 software on windows?

We will send the firmware to your email, you can refer to this page to upload:

I suggest you use Arduino1.0.1 to upload the firmware:

Okay new firmware uploaded and it works correctly now. But when I start a print in repertoire it only preheats bed before starting print, but the manual preheating extruded works, is there a setting I can change?
