you have a unipolar configuration. if you have a dmm, measure the resistance between each single wire and the common group, it should be similar. this will tell you if you have a burnt phase. if it is good then try the 6 different configurations on the motor cable. 1234, 1243, 1423, 1432, 1324, 1342. on each config try to run the motor very slowly like 50 rpm.

an other thing might be that the step and dir input on the board are not labaled properly and you send the pulse on the dir input and dir on the step input, this would cause the motor to heat because it is stalling at full current on a phase.
