I am hoping the group here can help me with a problem that I am having.

I am having issue getting my spindle to run correctly whether I select CW or CCW rotation.
I am just setting up the spindle control for the first time. Up to this point my spindle has been controlled manually at the machine.

Here is my setup. I have a LittleMachineShop 3900 Mini Mill (Sieg SX2). It has a brushless motor for the spindle so I am using the LittleMachineShop 4213 spindle control board. I have it connected to a CNC4PC C11G BOB. I have attached my XML file for reference as well. Wiring is per diagram Chris provided with the LMS 4213 spindle.

So using the XML posted I can get the spindle to turn CCW (M4) at whatever speed I choose. All good here. I can shut off the spindle with M5. However, when I go to turn CW (M3) I get no response at the spindle.

So I started trying to figure out the setup a bit more. I have the following core setup:


MY SETUP
Kernal Speed 35,000

Motor Outputs

Enabled Step Pin # Dir Pin # Dir Low Step Low Step port Dir Port
Spindle Y 14 0 X X 2 0


Output Signals

Enabled Port# Pin# Active Low
Output1 Y 2 1 X
Output2 Y 2 16 X
ChargePump X 2 17 X

Spindle Setup

CW Output1
CCW Output2

Spindle motor output - YES
Step/Dir Motor - YES

Spindle Motor Tuning

Steps Per Velocity Acceleration Step Pulse Dir Pulse
1000 1500 31.25 3 0

Pin Type Output
Start/Stop 16 Electromechanical Relay 2
Forward/Reverse 1 A/C Solid State Relay 1
AVI (SPEED) 14 Analog Output (0-10V) Spindle

I based this loosely on the CNC4PC sample XML and the manuals for the C11G and the 4213.

Now, if I add a Dir Pin of 1 to the spindle setup on Port 2, I can get the spindle to turn CW using the M3, but the M4 will turn for a bit and then stop.
I would like to be able to use M3 and M4 as necessary for tapping.

Anyway, I am open to any thoughts and ideas as I am by no means a Mach expert (just learning as I go along).

Arturo at CNC4PC was able to get me going. He was very helpful and his products worked perfect, just a lot of user error here

the setup in Mach needed to be:

MY SETUP
Kernal Speed 35,000

Motor Outputs

Enabled Step Pin # Dir Pin # Dir Low Step Low Step port Dir Port
Spindle Y 14 1 X X 2 2


Output Signals

Spindle motor output - YES
Step/Dir Motor - YES

Dont worry, you werent the first. I too have had the pleasure of a personal call from a few vendors here on the Zone and Mach including Arturo. Stand up people and all got me going.
