Hi there
I have Geetech Rostock 301 with mixer with GTM32 Pro board. I have 2 issues now, first one is that when I'm homing printer both X & Y homing correctly but not Z. Z is going up towards the end stop but stopping just before pressing the switch and gives the sound like when its blocked by something and wont go up to press the switch lever. Please see video.

Second problem I have is that when I'm sending printer from home position by pressing down arrow in Repetier Host by -1, instead of going 1 CM down it goes towards thew bed and i have to use emergency stop button to stop this.

1.You can change the direction of motor at the LCD>Print setting
2.You should check the belts of motors

Turns out there was a stepper driver problem and voltage. I have corrected them and all working fine.

Just sorted out reburning bootloader, and up and almost running...

Issue is that the Y-axis is only moving towards the rear. Even if i 'prepare>move axis>move y>1mm' xve or -ve values cause it to hit the microswitch.
All endstops are triggered in Pronterface.

I know there is a simple solution somewhere, but i am new to this and need guidance.

CTC i3 Prusa Reprap, with Geeetech 2560, and Marlin 1.1.8

// 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 false

You can try to change "#define INVERT_Y_DIR false" to "#define INVERT_Y_DIR true"

Did as recommended with Arduino 1.0.1 for
1) GT3560RevA FW from https://www.youtube.com/watch?v=eakm1zUF47s&t=1s
2) Marlin-PI3_Pro_B FW from here.
tried Marlin-bugfix-1.1x but failed:
expected constuctor, destructor, or type conversion before 'float'
constexpr float XY_SKEW_FACTOR = (

No change in any.
Have asked for replacement gt2560, as have swapped driver modules, motors wires, plug location on gt2560, and no improvements.

Other thought would be pins.h ? but all seem okay.

Dir of driver doesn't seem to change.

If only someone had factory FW for a CTC i3 pro B, then i might have a control test.

Have you tried to select the correct COM port and board type?
If it necessary,you can uploading your firmware to the Google drive and attach the link to the post

Yes always check Com and board.

Using ponterface, y axis moves still in 1 direction. but only allows the equall oposite amount, even though it is wrong!

also, M302 - Allow cold extrudes, does not work.
so got hot end to 180 (170 limit), and extruder does not work in either direction.

I switched motors from extruder and y-axis and both motors work, also switched stepper modules and they act the same.

Must be Fw or m/board.

Even before i upgraded to marlin i did a M501, and here it is:

echo:Hardcoded Default Settings Loaded
echo:Steps per unit:
echo: M92 X78.74 Y78.74 Z2560.00 E105.00
echo:Maximum feedrates (mm/s):
echo: M203 X400.00 Y400.00 Z2.00 E45.00
echo:Maximum Acceleration (mm/s2):
echo: M201 X1400 Y1400 Z100 E80000
echo:Acceleration: S=acceleration, T=retract acceleration
echo: M204 S1400.00 T5000.00
echo:Advanced variables: S=Min feedrate (mm/s), T=Min travel feedrate (mm/s), B=minimum segment time (ms), X=maximum XY jerk (mm/s), Z=maximum Z jerk (mm/s), E=maximum E jerk (mm/s)
echo: M205 S0.00 T0.00 B20000 X13.50 Z0.30 E5.00
echo:Home offset (mm):
echo: M206 X0.00 Y0.00 Z0.00
echo:PID settings:
echo: M301 P19.86 I1.00 D98.93

Which i put into Fw as recommended, but maybe that is the error?!?
