I moved it over to port 0 on my side and it worked fie and is safer like mentioned.  Since it's really not used from the port or modbus other than looking at logic calls in the brain it doesn't matter other than it may conflict down the road later and cause issues.  Port Zero will not cause any issues later so it's safer.

I'm not sure, but I think you save the Spindle warmup as a separate file.  You have to load that warm up file and not the one that you can post from the wizard.  Double check this by looking at the G-Code.

There is also a check box somewhere that says to use rapids and to move all axis at the same time and I had both checked.

That is a great guy huh, just helped me with my modbus issues and now he wants to help me with the warmup program.   

    I tried several different setups in the program to get it to run the spindle warmup concurrent with the axis warmups and it still will not run without these annoying pauses.  The machine is working fine and seperately the warmups seem to work fine, just not together.  The settings for the spindle are quite simple in the wizard so I dunno what I could have checked to make it work this way. Perhaps it is a setting in mach?  I looked thru these as well with no luck. Perplexed...hmmm...

  I will try to find the link to the warmup/breakin program and post it here....peace

Oh, earlier this year, Sangmutan had lots of problems with weak motors and controllers.  Mid year they redesigned them and said they had them fixed.  I bet you could push Syil into sending you a new style.

I had the same exact issues with my Sangmutan 1100 watt I bought from Keling.  After waiting for a fix I finally asked for a refund which they did do and then replaced my motor with a 3 phase motor and VFD.

It's works fine except that I cheaped out and bought a borderline surplus 3/4 hp motor the first time.    Get you a good 2hp baldor or marathon motor and a VFD Vector drive and install and that will fix your spindle issues.

I drill and tap holes with mine and have complete control over what it does.  The Sangmutan, your leaving someone else in control and they are pretty non responsive about taking care of issues.

It not only has no torque it just shuts down in the middle of a cut randomly. It doesnt matter if you are cutting .001 " or .100 "

Pete,
Mine works properly.  It's probably a user input issue
It took me a few times playing with it before I got the spindle to work in harmony with the moves.  Once I did, the table & z moves like it used to and the spindle stays running and changes speeds.

I would have to go in the shop and see how I have it configured.
I can't test right now because my spindle is torn down  (belt drive).

You got a link to the warmup wizard?

That is what I have mine set to.  Really though, I need to experiment because I think it can be any port that is not 1 or 2.
You have to enable them so when M2 and M4 is used mach is enabling the output (in logic)  The brain looks at the outputs logic state and sends a modbus command to the spindle.

Think of a 3 way boolean statement;

If (output5 = 1) then M3
else
If (output6 = 1) then M4
else
M5

Output5 -> Formula A*1 -> Modbus Register 0
Output6 -> Formula A*3 -> Modbus Register 0

Set Outputs 5 & 6 up for Port 3  (Modbus)
Set outputs 5 & 6 up for Spindle Control

Thanks for the Kudos Pete.
I mainly started from scratch and quit trying to modify all the examples out there.
Brains are checking the status of the Spindle Outputs and sends the proper value to the VFD register.  Easy and Done!!

My main propblem wasn't with the modbus portion,it was understanding how to use the brains.

Heck Greg, Pete and I've been stuck on this for months so it's getting frustrating....
