If a better PSU doesnt resolve this I will do the same.
Cashflow permitting.

Have Gecko's on the Servo's and dont have ANY issue's there

lol

I get razzed alot about my use of "Logic"

All I know about the driver is its a model # U366B
Bought the kit on Fleabay a few years ago and It came with two 460 Ouncers and a 140 for the Z.
The power suppies are most simple.
3 transformers that feed through a Cap and to the driver .
Hey , I was totally ignorant to CNC when I got it ... LOL

Here's my thoughts on this . Keep in mind I'm mechanically minded and a electronic retard .
I have the bench mounted Mill/Drill , a Rung Fu 31 clone from Harbor freight.
The quill is spring loaded.
Moving up is a tad easier than moving down as the spring is in play.
Im tweaking the spring now to try to equalize the effort.
But if the Motor had more UMPH , it wouldnt be a problem .
Sound Logical ?
I can mount the 460 OZ if I have to . but man that seems like overkill.

Thanks ..
I think I might know why I'm having the issues with my z motor.
If I get it to jog fine then it stalls running gcode moves.
then I tune it to work with GCode and it stalls on jog !!!   OOiy

The stepper driver requires a 15V to 35V pwr supply .
Guess what the kit came with .. 15 !!!

lol   
Im gonna get a decent 30V supply and see if she acts better.
the motor spec is 2.5 V

Just in the testing phase ..

Think I got rid of the noise.
Had all my cables tied together tight as a Tick ..
Must of had some induction going on.
Here's another one for the guru's out there ..
I can jog till the cows come home .. smooth as silk.
but when I run code (Roadrunner)
The z motor loses step sometimes .
By the end of the run Im barely cutting metal ?
Why would my stepper choke on a slow jog when it's gravy on a regular jog ?

All the cables are well sheilded.
This didnt start until I set up the z motor so thats where Im gonna start.
Connections are all correct and tight.
Might need to get a better stepper driver. But money is way tight right now
