Marlin-1.1.8 (05022018) firmware for I3 A pro

Post by Hamed » Sun May 06, 2018 7:10 pm

here is the latest Marlin firmware customized for I3 A pro (lead screw), you don't need to do any modifications expect my name in welcome message ;)
it works great, manual bed leveling is enabled and works well, you can compile it with any version of Arduino compiler.

enjoy.

Hi,

no but you can download this firmware and change the numbers in line 533 in the file "Configuration.h" to your previous firmware.

(#define DEFAULT_AXIS_STEPS_PER_UNIT { 80, 80, 400, 93 })

I loaded the firmware and it works well. I can level the piano but when the printing starts, the noozle is too high. which commands do I have to write in the slicer gcode to take account of the leveling?
Thanx

1, Have you homed it each time when you leveled the bed?
2, Check the Z offset or reburn the firmware

in the order:
1 homeper all the axes
2 I perform manual leveling on 9 points
3 store the setup
4 launch the print and the noozle is still too high, maybe I miss some command in the slicer g code?

Hi

add "M420 S1" G-code after "G28" home all axes in your Slic3r printer settings (custom G-code) to enable Z offsetting before start printing.
