I am a total newbie.  Please be patient.

Hardware: ESS rev 2 Build 216, BOB: C11G Board Rev 9, Home made CNC Router
Software: Mach 4 ver 2.0.3481 Demo Mode

5v power to both boards.  58.7v to stepper drivers.

Running Mach 4 in Demo mode I can not get stepper motors to move.  Trying jog, keyboard and MDI.
All lights are lit.  ESS top green is steady. Bottom green flashing.  EStop is communicating with BOB and cleared.
Screen shows they are moving.

ESS Diagnostics in Mach 4 only show odd pins(dir?) working when keyboard is pressed.
My stepper driver documentation says they run enabled by default.

Do I need to change JP3 jumper?

I have double and triple checked wiring, connections port output settings.  Watched as many videos as I can fathom.
Searched forums and at a loss.

Please help.

Hi,
what screenset are you using?

If you have a look on the Machine Diagnostics tab with Mach Enabled what is the status of output LEDs M0, M1 and M2?

I am using wxRouter.set.  I am unable to find the machine diagnostics  tab, but I'm trying to edit now.

Hi,
may I suggest using wx4.set to start with, its one of the older and more developed screensets.

Craig

Just did.  M0, M1 and M3  and M3(Slave to 0 running in reverse) all Enabled.

Hi,
kool.

Try MDI
g0 x5
x0
x5
x0
x5

Should see x axis move back and forth 5 units. Keep a watch on the BoB you will with any sort of luck
see an LED turn on and off as a result.

Craig

Tried that and nothing happened.   Screen showed it moved, but no actual movement. No LED on BOB.

Hi,
OK it sounds like Machs OK but either communication to the ESS from the PC is faulty or alternately the BoB is not responding to the ESS.

Do you have any indication that the ESS is communicating with the PC?

I'll track down the reference but seem to recall the LEDs of the ESS have a distinct pattern when communication is established.

Craig

Hi,
this is on the Warp9 site and refers to the LEDs in the top of the Ethernet socket:

The Ethernet Jack has two LEDs on it. The upper left one is yellow. This is an important status LED. It represents the status of the Link Layer. If a link has not been established, the yellow LED will not be on. The link layer is a low-level Ethernet layer that needs to be present between your ESS and your PC in order for the higher-level communications to run.

Confirm the Yellow LED.

i would start with a simple ping
