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.

Yes that sounds logical, your name Spok by any chance ;)
Just out of interest what make driver are you using?

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

Werent we all, and I still am ;D
I was just curious as I bought some drives off eBay and had endless problems with them, eventually went to Geckos and never looked back.

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 :)

Anybody know off the top of their head what that Pulse step setting
in the motor tuning section does ? (0 to 5 option)
Im at work and dont carry the manual with me :)

Hey Yoda,
    The best I make of it is  It is the duration of time the step signal is sent. Mine is set to 7.
;D If you could see the things I have in my head, you would be laughing too. ;D

My guard dog is not what you need to worry about!

7 ??
I thought it was only 1-5
Maybe I should bring mine up on the stepper axis .
Its at Zero !

Yoda, I'll be honest, I don't know why it says 0-5. I do know that mine likes it at 7 though. I don't think it will hurt any thing to try.

I'll give it a shot..
For Hood.
Heres the specs on the driver

 Standard 5V TTL CMOS Enable, Step and Direction inputs interface with virtually all step and direction controllers including Microchip PIC, Atmel AVR and PC parallel port CNC software.

 This state-of-the-art, high power drive is very conservatively rated at 6 amps per phase.

 Maximum step rate for this drive is over 200 KHz.

 Connecting the Enable input to Ground disables the outputs of the drive so stepper motor shaft could be rotated freely.

 High quality screw type terminal blocks with sliding pressure plates (will not fall apart when wire is removed) on all inputs and outputs, make connection to this drive very easy and reliable.

 Half or Full step operation is set with an on board jumper.

 Stepper motor current is adjustable from 1.5 to over 6 amps via an on board trim pot. This drive does not require any external power resistors to set the stepper motor current.

 This drive features automatic stepper motor idle current reduction to 25% of full current. This feature could be defeated with on board jumper so the motor runs at full current all the time.

 Drive is mounted on custom designed, heavy yet compact, heat sink for cool and reliable operation.

 Drive has dimensions of 3.2" L x 3.0" W x 2.5" H.

 Drive is designed to perform, be efficient and last a long time.
