Hello,
I am a complete newbie. I have ordered a 4-axis drive system without stepper motors. I already have a 3-axis system that was shipped complete, was turn-key and operated perfectly out of the box. Now, I need a 4-axis box. In order to avoid purchasing a complete 4-axis system with 4 new motors (which I don't need) and spending at extra $150 or so, I have purchased a 4-axis system with no motors.
The new system comes with set-up instructions as shown below. I think I just need help with steps 2 and 3. I will purchase a multimeter from HarborFreight as soon as the drive box arrives.
I can send a pic and a schematic of the drive box - if that would help. You can also look at
www.xylotex.com, which is where I purchased the system.
Can you help?
Best regards,
Jay
[01] Turn Red Rocker power switch OFF, then Plug in IEC power cord (supplied) to Box and 110VAC power outlet.
[02] Turn ON Power Supply and measure that the DC voltage does NOT exceed 30VDC (27.5V is a good voltage to use). A red LED and the fan should both power up
[03] Adjust the Vref at REF's (Black Lead to GND, Red to XRef) Turn Potentiometer counterclockwise for +. Vref = Motor Amp/Phase * 0.8 (i.e. a 2.0A/phase motor X .8 = 1.6V) Never set Vref higher than 2.0V.
[04] Turn OFF Power Supply, and wait until the supply is fully discharged before proceeding.
[05] Unplug Green Screw Terminals from drive board.
[06] Feed motor cabling through grommet hole on back panel. Leave the panel seated in the drive box bottom half to help maintain rigidity of the panel (acrylic).
[07] Hook up stepper motor cabling to Green Screw Terminals.
[08] Make sure that the Motor Phase wiring is correct, and that there are no stray wires to cause a short. A mis-wired phase or short can destroy the drive board.
[09] Double check motor connections.
[10] Plug in screw terminals
[11] Turn ON Power.
[12] The motors should "lock up" (not turn with finger pressure).
[13] Use PC running program such as Mach3/4 or LinuxCNC to control the box through the PC parallel port and a user supplied parallel port extension cable to the drive box.
