I have build the mpcnc and want to use it as a laser engraver. The complete hardware build was finished, but now i am stuck at the elektronics (i am an electrician by the way). So the motors don’t move, as i said them through repetier-host.
They make funny sounds, like a small Alarmhorn
I have changed the driver, but nothing changed
I tried a diferent connector on the ramps 1.4
On the ramps itself is the firmware downloaded from the assembly guide
The false thermistor is also in its place
Another problem is that the LCD only shows 2 rows of white squares.
I hope anybody can help me.
thanks for the fast answer
But i have found the issue
I forgot the 3 little jumper under each driver
So now the motors are working
But the display is trying still showing two white lines
I am using a ramps1.4 set from ebay an flashed the firmware from here https://www.v1engineering.com/marlin-firmware/
On it
