Need Help!- Buying Drivers and power supply AGAIN!

[mulligan]

Starting from scratch again... I purchased the K179 drivers and power supply a year ago and recently found that they have proven to be quite in adequate for my Oxy/fuel/plasma table. My budget for the table is about nil right now so the best bang for the buck parts is needed.

I have two Keling 289oz and one 425oz. At the current time I will only be running two axis.

Which of these will be my best bet and why:

1. http://www.hobbycnc.com/products/hob...er-board-kits/ - 95.60 incl shipping + power supply

2. http://www.xylotex.com/3AxWPS.htm - 205.00 + shipping

3. http://cpwojcik.home.att.net/QSDriver/Page_1x.html - 210.00 + shipping + power supply OR 2 drivers + quickstep software + Pulse Spacer incl shipping - 250.00 + power supply

Also is there a 'universal' power supply I can buy that I can use for any of these?

What about this one?

http://www.xylotex.com/24VDC_4-5A-PowerSupply.htm - 50.00 + shipping
Or

I've been suffering from information overload for the last couple of weeks and need someone in the now to advise me.

How big is your table, and what is your method to convert rotary movement to linear movement, screw, rack......? You might want to look at this: http://pminmo.com/PMinMOwiki/index.p...chanical_Power

y table is 5'x9' with a useable space of slightly more then 4'x8'.

I have a timing belt setup now. Not sure how well it works yet due to issues with my power supply.

I have 10t on my motor to a 30t which is on a shaft with a 20t that moved the axis... I'm not sure if I am geared low enough.

I lucked out with an old Compaq Desktop Pro I had with a 200w power supply. After reading info on these pages (http://www.wikihow.com/Convert-a-Com...b-Power-Supply and http://www.directron.com/2powersupplies.html) I was able to set it up to run my current K179 drivers.

I will still need to order some higher quality drivers to optimize my setup... but I have no idea the pros and cons of each.

A year ago when I order my current hardware, I thought I was set...

Can't say that I understand the relation ship of the three (10t, 30t, 20t) ? Is one of them a rack?

Getting the mechanicals right first will help you in the end, otherwise you will be spend more money on power supply and drivers.
