Hi all

I have this setup

PoKeys57CNC
3 * NEMA 23 - 0.7Nm - 1/4" shaft (1=Z, 2=Y)
NEMA 23 - 1.3Nm - 1/4" shaft (X)
Power Supply - 24V 10A (Noname)
Stepper Driver 2.5A - PoStep25-32

My problem is when I crank the current up for the Y-axis. RIght now my settings is 1Amp for X-axis, 0,5A for each stepper on the Y-axis and 0,5A for the Z-axis. I would like to run the two steppers on the Y-axis with more current, because I have understood that this will give them more torque, and right now (with only 0,5A each) they do not have power enough to run to the bottom of the Y-axis, it is like my dragchain is simple too heavy for it to drag it (hope it makes sense?).

The stepper drivers I am using have a jumper to switch current for the steppers (0,5; 1; 1,5; 2; 2,5), when I just try to increase each Y-axis motor to 1A, a relay shots in when trying to power on the setup, and it wont start.

Does anybody have suggestions for some troubleshooting I can do, or have anybody tried similar things?

Thank you.

(hope this is the right place to post, else please let me know)
