I do hope you can help please, as I have been trying to sort this out for the past 12 months. Thank you for posting but is there any chance you could post one for the original A4988 and auto bed leveling enabled. Mine has a 3D Touch. https://www.thingiverse.com/thing:2039119 And I have set the sett...

here is the firmware for my I3 A Pro printer which works accurate and very quiet with TMC2130 stepper drivers on X and Y axes.

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.

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 })

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. https://drive.google.com/file/d...

Hello all

can I use this firmware for I3 A pro without any modifications ?

thanks

it solved by increasing output current of Z stepper motors driver.

I just assembled my printer but the z axis move very badly I mean the torque of motors is very very low and I had to almost open all the screw of the T8 lead screw nut that motors can move the z axis but I know it's not good solution and will reduce the quality of the print so what is the best solut...
