Dony be fooled into purchasing a power supply with a larger current rating. The power supply is a perfect match for the G540.

If you do want a decent all-in-one drive that's slightly higher spec than the Gecko then look at the Leadshine MX3660 which is only 3 axis but as 60Vdc digital drives along with inbuilt BOB and spindle control. Homann Designs Gecko G540 Stepper Drive + 48Vdc 7.3A Power Supply G540-PS - This is a Geckodrive G540 REV-8 plus a Meanwell 48Vdc 7.3A switching power supply. Save and wait until you need them then buy good quality Digital drives along with correctly sized PSU.
So my advice is to look at individual drives and don't buy anything yet. Also your restricted to aprox 42-45Vdc to leave a safety margin for back EMF.

The G540 can run 4.2a motors but you loose the Idle current reduction feature which means the motors get hot when at stand still. SPW Industrial warrants this product to be free of defects in workmanship and material under normal use and conditions for period of one year from the date. Machine your size if robustly built will most likely be best run on nema23 motors which if sourced in Europe will most likely be 3Nm and 4.2 and for best performance you'll want to run them on 75-80V drives with 65-70Vdc PSU. The Gecko G540 is a nice bit of kit but it does have some limitiations like restricted to 3.5a motors and still use all it's features, Plus restricted to less than 50Vdc for running motors. Neale is correct it's a little premature to be recommending or even thinking of buying anything yet if you haven't even designed the machine. So, get a good understanding of what you are trying to do (what do you want to cut, home/industrial use, etc), get a design put together, and post on this forum for comments. There are others but I only have personal experience of these. They probably will not be as cheap as you might find via eBay for what sounds like similar kit, but they are good people to deal with and sell decent quality goods.

This high quality, full featured aluminum enclosure has mounting holes for the 4-axis gecko g540 stepper driver. Once you have finished your design to the point that you can safely specify the hardware, then a couple of good UK-based suppliers that I have used are Zapp Automation and CNC4You. Heatsinking is a kflop for the dmz of stepper motor. Often, they have bought cheap kits from eBay/China, and suffer from poor performance or unreliability or both. I don't think that any of the experts on this forum would want to specify hardware based on your specification! There are too many people who have bought the wrong items at the beginning of a project and created a lot of problems for themselves.
