Mesa7i96s and Postep60-250?

I just migrated from Mach4 and Pokeys57cnc, and was hoping to keep Postep60-256 drives in my new setup. I wired postep drive to Mesa 7i96s as follows: Postep pins 1/2/3/5, 2 to TB1 pin1 (GND) / 3 to TB1 pin5 (DIR+) / 5 to TB1 pin3 (STEP+) and 1(enable) to TB3 pin13 (OUT-).
I have been at it for about a week now, I can’t figure out what I am doing wrong. Using Pncconf wizard, the home/limit/ estop are working but the drives are not getting enabled and the stepper motors are not getting any pulse.
any help would be greatly appreciated, thank you in advance!
ps! I am very new to Linuxcnc, migrating from Mach for almost 2 decades.

Can you show a bit more about how the enables are wired?

What is OUT0+ (TB3 pin 14) connected to?

Mach was running Via Pokey57CNC. I think I just got tired of Mach, LOL!
the thing with Postep60-256 Enable (inverted, 0=enable, 1=disable).
I am using LINUXCNC 2.9.4 and I am using AXIS for now until I get it up & running, trying to test with 3 axis  with the goal of a total of 6 (gantry has X1 & X2).
using engmate power supply 36V 10A
wiring is as follows: AxisMesa connectorMesa pin (TB1)Mesa signalPoStep60 IDC pinPoStep signalX1 (master)7i96S TB1Pin 3STEP0+IDC Pin 5STEP  Pin 5DIR0+IDC Pin 3DIR  Pin 1 (TB1 GND)GNDIDC Pin 2 (or any GND pins: 2,4,6,8,10)GNDX2 (slave)7i96S TB1Pin 9STEP1+IDC Pin 5STEP  Pin 11DIR1+IDC Pin 3DIR  Pin 7 (TB1 GND)GNDIDC Pin 2GNDY7i96S TB1Pin 15STEP2+IDC Pin 5STEP  Pin 17DIR2+IDC Pin 3DIR  Pin 13 (GND)GNDIDC Pin 2GNDZ7i96S TB1Pin 21STEP3+IDC Pin 5STEP  Pin 23DIR3+IDC Pin 3DIR  Pin 19 (GND)GNDIDC Pin 2GND
for the enable I tried to use TB3 pins 13 (OUT-) connected to pin1 of all 4 drives (enable pin) and pin 14 (OUT+) connected to Mesa GND. 

Typical issues with step/dir  not working are wiring or step pulse length being to short

I would make sure the initial step pulse length is at least 5 usec (5000 ns in LinuxCNC)

For the enable (since its active low) I would connect all enable pins to a say 1K pullup resistor
(so they default to being disabled) then connect OUT0+ to all enables and OUT0- to the drive
ground pin

 

so sorry for the mumbo-jumbo I created earlier attached is a pdf for the pin locations   

Yep, consider that when static, a 5A stepmotor may only drop 3 VDC so ~15W.
So with a 48V driver, only about 400 mA at 48V is needed to get 5A at the motor.

 

Thank you guys so much for the heated debate about power supply. I have 2 power supplies each powering 3 of the drives. it worked like a charm with Pokeys57 board. I am not getting any juice out of the drives to the stepper motors, I tried the 1K pullup resistor, no luck. I to use a 10kΩ pull-up resistor from each PoStep Pin 1 to Pin 9 (+5V) to ensure drivers default to disabled state. and still nothing. I really don't want to go back to Mach4 & Pokeys board. I am just hitting a wall! 
Thank you!
