X Y Z Max and Min size

Vertex 3D Printer Vertex - Issues while printing
1

Hi,

I have changed the mother board with a new one from Velleman. (The old mother board has burned due to a bad manipulation)
After replacing the mother board, I flashed the firmware with the last available as download.
When I autoHome the head, all is fine, the head does to rear right corner.
But when I move the head on the X axis to position 100 then the head goes completely on the left side. (same for Y and Z)
Impossible to go to position 0,0
The middle of the bed is now at coordinate (X=150,Y=150) and the front-left corner is (X=100,Y=100)

I’ve tried to print a small part, this is 2 size bigger as expected.

How to solve this?

This sounds like there is an issue with how the stepper motor drivers are configured (1/16 microstepping rather than 1/32 on the PCB), or the number of steps per mm in firmware.
Perform a “Restore failsafe” on the printer screen after a firmware update. Could well be the issue. What is your steps per mm setting for Xsteps/mm, Ysteps/mm, Zsteps/mm & Esteps/mm under “Settings -> Motion” on the LCD screen?

When you updated the firmware did you use the Arduino software version 1.0.6 or below?
If not you can download it from here
