I must change my board sanguinololu by a new gt2560 REV A+ on my Geeetech prusa i3 Aluminum diy and i have some problems.I have downloaded Prusa I3A 2560.zip,is this firmware for my Geeetech prusa i3 Aluminum diy ? or another ? after installing this firmware, my z axe is only up and not down but all the 2 motors are ok, my y is on the bad sens and x yet. Y and X have a noise but move slowly.
Can you said to me wich exact firmware (name of this) i must install on my Geeetech prusa i3 Aluminum diy please. And what kind of settings i must change to have all my axes in the good direction. I was very happy with my Geeetech prusa i3 Aluminum diy and i hope to find a solution to install my GT2560 rev A+ on it soon ). Thank you very much to all for your help. Here is description that what i have :
About wiring i have check 5 differents picture and i think that my wiring is ok, i have connect endstop to X min Y min and Z Max, and i have check my stepper A4988 installation they are install on board in a good sens.
Board: GT2560 Rev a+
Stepper : A4988 install on board
Printer: Geeetech prusa i3 Aluminum diy with T8 threaded rod
Thank you very much to all for your help
Best regards Oliver
I don't know if you have already found a solution but I have done almost the same.
I have upgraded to a GT 2560 Board but I added TMC 2208 drivers for XYZ as well as a BLTouch Sensor and a 12864 graphic display.
I was able to adapt the configuration file of Marlin 1.1.9
Please check the motor type and direction in that section and reverse the axis if needed:
Code: Select all
#define X_DRIVER_TYPE TMC2208_STANDALONE //#define Y_DRIVER_TYPE TMC2208_STANDALONE //#define Z_DRIVER_TYPE TMC2208_STANDALONE //#define X2_DRIVER_TYPE A4988 //#define Y2_DRIVER_TYPE A4988 //#define Z2_DRIVER_TYPE A4988 //#define E0_DRIVER_TYPE A4988 //#define E1_DRIVER_TYPE A4988 //#define E2_DRIVER_TYPE A4988 //#define E3_DRIVER_TYPE A4988 //#define E4_DRIVER_TYPE A4988
Direction can be modified here:
Code: Select all
// Invert the stepper direction. Change (or reverse the motor connector) if an axis goes the wrong way. #define INVERT_X_DIR false #define INVERT_Y_DIR false #define INVERT_Z_DIR true
I am just using a single extruder and want to use the free thermistor input on the GT 2560 A+ for a enclosure temp sensor. But I do get errors when I try to activate the 2nd sensor with only one extruder.
Anyone an idea on how to get the 2nd sensor for enclosure temp without using a 2nd extruder?
