Pursa Y axes move only one way

Dear Rep_Rapers!

I have got a big problem! Actually I'm building a Pursa 3d printer. Every endstops are working well and everything is OK.
BUT one thing doesn't let me to calm:

-I use Printer Interface (Print_Run)
-When I send a sign to Y stepper motor negative directon it's move on.
-When I send a sign the positive direction the table is moving negative direction same.
-The endstop works good.

Please HELP me !!! I suppose that something is went wrong in my Sprinter Firmware , but I don't know what.

... check the assignment of the pins for CLK and DIR for the Y-axis.

There were some issues with double-defining pins with active JTAG interface or selecting the wrong board/pindefinition while compiling the firmware ...

Sorry but I don't know what is CLK ? Today I tried to flip the Y axis's motor connection but it just caused that the Y direction changed.
I use Sprinter firmware
Arduino MEGA 2560
RAMPS 1.4
And Printerface

When I push the +10Y direction on interface it move toward 10mm
When I push the -10Y direction button it cause the same

... there should be two pins for controlling every stepper driver - one for the direction (mostly named DIR or CW/CCW) and one for the stepping clock (mostly named CLK or CLOCK).

You may chek, if the polarity of the direction-pin will change, when changing from CW to CCW (or +/- for a single axis) and driving the motor.

Most issues with motor direction misbehaviour are connected to the endstops not connected properly, but if your motor drives in the same direction if you drive them + or -, then it's something with setting the correct values to the stepper driver pins ...

And How could I check the Stepper driver pins? I found a part of sprinter firmware which one name is pins.h------- I found this there:

I think something here is wrong. Have you ever used this Firmware?

... this are the pins for the Y-motor - pin 60 will emit a short pulse for every motor step, pin 61 will be high or low regarding of the motor direction set by the software.

As you seem to have problems with the direction only, you can measure the voltage from pin 61 to GND and check, if it's changing accordingly, when you drive the axis manually controlled left or right.

If it's not changing, then either your pin configuration is set wrong, you have a connection/wiring problem or the driver is damaged ...

I Measure the voltage from pin 61 to GND, and you are right. The voltage didin't change. The other three pololus are working well. The voltage is changing betveen 0.00-5.00V so now I try that pololu in an another Slot. I hope only just the wiriing wrong or the software.

If in the software went wrong something I suppose it's somewhere around the Y_PIN configuration. Every configuration guide says this confirutaion so I don't know how could I solve this problem.

... I've read somewhere, that with some processor/board options (JTAG?) specific pins were defined double, so won't work as expected ...

Ohh realy? It's very good news so I search that topic . This problem is a big Mind fuck for me DDD. I hate this one.

THanks a lot VIktor! I found a topic : [forums.reprap.org]

I think i have a Same problem . The JTAG is enabled (factory default). And the JTAG is disabled pins 4-7. THis is why doesn't move the Y axis.
