Hi all. Has anyone gotten the display to work? I connected it with a sandwich and, as in the picture, the display was completely illuminated. with stellarium the engines get warm, sometimes they hum quietly, but there is no movement. I made the changes that were in this thread. 8825 was set to 70% of the maximum motor current, checked the ramps on the Marlin firmware, everything works. #define AZ_ENABLE_PIN 38 // RAMPS 1.4 X stepper
define AZ_STEP_PIN 54 // RAMPS 1.4
define AZ_DIR_PIN 55 // RAMPS 1.4
define AZ_STEPS_PER_REV 0. // My value: 119467.0 // How many steps the stepper motor needs to complete for one a horizontal 360degree revolution of the telescope (my setup: 3200 : 1 and 560 : 15)
define AZ_MAX_ACCEL 300 // Maximum acceleration for the azimuth stepper
define AZ_MAX_SPEED 4000 // Maximum speed for the azimuth stepper
/*
Altitude stepper
Direct Drive: Axis 2
Dobson: Altitude (vertical) axis
Equatorial: Not implemented; Declination axis
*/
define ALT_ENABLE_PIN 56 // RAMPS 1.4 Y stepper
define ALT_STEP_PIN 60 // RAMPS 1.4
define ALT_DIR_PIN 61 // RAMPS 1.4
define ALT_STEPS_PER_REV 0. // How many steps the stepper motor needs to complete for a vertical 360degree revolution of the telescope (my setup: 5.18:1 and 3200 : 1 and 105 : 12 = 147840.0)
define ALT_MAX_ACCEL 400 // Maximum acceleration for the altitude stepper
define ALT_MAX_SPEED 10000 // Maximum speed for the altitude stepper

what should the values be? can someone post a working sketch? and how to connect the display. Thanks everyone
