Hi I have just finished building my prusa v2 with ramps 1.4 running the latest marlin firmware from [
github.com]
I am wondering what the procedure is when I send a print to the printer. I'm using pronterface and slicer to control it.
What I see is
all axis home, hit home limits and come off it by 5mm or so and back onto home limit
Then my print waits for hbp and extruded temp to come up to desired temps
Z axis now lifts about 5mm up and a countdown begins in pronterface
Once it finishes the count down the z axis drives back down to home position
x and y axis now drive to the centre and the print starts.
The reason I ask this is I am in sure why my z axis lifts up and drops back down then prints, it would make sense if it lifted up 5mm then moved to where the print starts and dropped back down to desired first layer height.
Is this what should be happening?
Cheers Ash.
