Are the Y and Z axis motors locking up when power is applied to the corresponding drives?
Welcome to the Zone!

Hello gentleman/ladies!
I am having an issue with a CNC Router and would really appreaciate some guidance if possible.
Long story short, I bought an used JInan CNC Router 5' x 4' (chinese) which had a configuration problem (in my opinion). The problem is when all cables from the drivers are connected to the CNC machine and I try to jog on Mach 3, only 1 axis moves - which is the "X". I have tried removing the cable off the "X" and plugging it to "Y" and "Z" and ALL axis on the machine do move when I jog in Mach3 - meaning the machine is working. However when I try to jog those axis that do not work, I see the coordinates move in the Mach3 Software but not on the machine.
Please take a look at the video I made in regards to the problem I have:
I will attach the following drawings for reference:
- a picture of the machine I purchased.
- a really bad diagram sketch of the electric connections between the breakout board and drives (hopefully some of you understand it LOL).
- a picture of the breakout board my setup has,
- my setup in Mach3
Thanks for reading!

When you say you removed the cable what are you referring to IE removed the cable from the stepper motor or removed the cable from the stepper drive or removed the cable from the breakout board?
You must give accurate detailed information and post additional images so that we can help you.

Can you upload here also your MACH3MILL .XML file? are you using the parallel port? or the USB? i`ll try to load your .XML file here in my mach 3 so that I can take a glance on all the settings that you set. by the way it`s located in c://mach3 folder, copy the mach3mill .xml file, zip it then upload it here
Are you using three different drivers? That wiring diagram is very confusing and messy. You must draw straight lines. My eyes gets crossed trying to follow that messy diagram... Have you looked at the driver documentation? If X and A are working and when you connect the Y and Z motors to the X drivers then they are working also in that case maybe those Y and Z drivers are incorrectly configured or incorrectly wired. I have the DQ542MA drivers, but never used any of the other two. In my opinion it is not a good idea to mix drivers, so I'd buy two more DQ542MA drivers and would get rid of the others.
Another thing... in my opinion A and X should NOT share output, they should use their own stepper output otherwise you will not be able to slave and square the machine since both stepper will simultaneously receive step and dir pulses.

No, Y and Z do not lock up when power is applied... I removed the cable from the X drive to the stepper motor and tried connecting it to the Y stepper motor and Z stepper motor (and both axis do work when I do this).
Thanks!
Ok I will do this later on the day. Thank you!
Yes they seem to be different drives (I will keep in mind is not good using different drives, I will buy some online since they are cheap). I will try to make a better drawing once I have some free time. I do believe the Y and Z drivers are incorrectly configured (I have the same connections as the X drive - which works), however I am not sure where the error in the configuration is.
I am thinking of the removing the A axis and just using 1 power supply for X, Y and Z. I can do this correct?
Thanks for your input!
Disconnect the enable wires from the offending axis drives and check to see if the corresponding motors lock up.

Please post some images showing the stepper drives with the wiring visible.
