Will_D:
I only have X & Y axes fitted with steppers.

For debugging these are disconnected from the drivers.

Alll I am doing is driving the controller's axis displays.

I just wonder is it the usb stick??

Will try a different one when the garage warms up.

I am sure the g-code is good as estlcam runs it ok (in sim mode - no Arduino connected)

Thanks for all the help.

Will_D:
Should have posted the above earlier!!

Anyways an update:

Tried different memory stick and same problem.

Ran the code on the SMC4-4 (no hardware connected) and all worked fine.

philf:
As has been suggested try adding a feed rate (F100) e.g.

(Project Mill_Test)
(Created by Estlcam version 9 build 9.046)
(Required tools:)
(End mill 3mm)
F100
G00 Z5.00
G00 X50.00 Y-1.50
G00 Z0.50
G01 Z-0.50
G01 X51.50 Y25.00
G01 X0.00
G01 Y0.00
G01 X50.00
G00 Z5.00
G00 X0.00 Y0.00

Maybe the controller assumes a feed rate of zero if you don't put one in and it would, understandably, never get anywhere.

I wouldn't worry about a spindle speed at this stage but it can be added with e.g. S1000

Your GCode doesn't draw a proper rectangle by the way - it draws a non closed shape with a sloping right hand side!

Phil.

This is a simple online g-code simulator, just to check the file eventually...
my 2 cents..

Will_D:
Thanks Merlin, Nice simulator.

As expected the code looks fine on the sim - just as expected.
