[QUOTE="me2, post: 367121, member: 3825"] All the parts are ordered. Here is the parts list. The X, Y and Z axis guides as listed in a previous post. $450 2x NEMA 23 stepper motors, 570 Oz in, for X and Y axis $110 2x NEMA 23 stepper motors, 355 Oz in, for Y and Z axis. Don't know which one I'll use for the Y axis yet. Want to keep weight down on the cantilevered arm. $78 1x Gecko G540 4 axis stepper driver. 3.5A, 50 Volt $250 1x Toroidal power supply, 48V, 13.5A $140 2x NEMA 23 belt drive pinions $180 2x 4 foot racks $90 1x wireless USB pendant $125 2x cable chains $70 Total $1493, plus shipping charges. Not included in the parts list is the NC controller and a PC and miscellaneous wires, hardware, limit switches, etc. The stepper driver (Gecko 540) is more than I need, ie 4 axi instead of 3. I might add a 4th axis for cutting pipe in a chuck or something like that. I also purchased one extra NEMA23 stepper motor. That is in case I convert it to a gantry at some point. Ditto on the extra axis on the G540. I am probably going to use GRBL as my NC controller. The board for it is $35. I feel as though the parts I am using are as good or better than most of the turnkey lower end CNC plasma tables. I thought about using servo motors, but couldn't justify them on such a small table. Most of the guides on lower end plasma tables are roller bearings on cold rolled steel. They can be troublesome. My motors are as large or larger than most entry level systems. I think I should be able to put together a nice little plasma table with these parts. My target cutting size is still 2.5 feet x 3 feet. I'll provide pictures and specs as I work with the parts.
