I am stuck here, I used Morays code example for rigid tapping but its not working. I was hoping this would be easier than it seems to be. All the values are being passed, which I checked with the console.

I have attached my test g-code, my C program, and there is a link to a YouTube Video of what my machine is actually doing.

For spindle control I am using "DAC" on the tool setup screen.

What seems to be happening is the Z axis comes down to the retract plane height of Z0.150 and stops then waits a second, stops the spindle motor, retracts and goes to the next hole. It stops at Z0.150 hesitates and then retracts to complete the program. During this last retract it starts the spindle motor again.


Thanks,
Dan

Hi Dan,

Did you configure the defines for your system?

What is printed on the KMotion Console?

Yes the #defines are all correct for my machine for the I/O bits, I have not touched MAXERROR, TAU, MAXSPEED, OSFACTOR, OSCONSTANT, STOPFACTOR.

Here is the console output

Bottom = -0.950000
Retract = 0.150000
Peck = 0.000000
Pitch = 0.062500
RPM = 250.000000
Units = Inches
Axis = 2
AxisRes = 50800.000000
Bottom = -0.950000
Pitch = 0.062500
Tap Complete. Minimium Depth Reached = 0.150000


Bottom = -0.950000
Retract = 0.150000
Peck = 0.000000
Pitch = 0.062500
RPM = 250.000000
Units = Inches
Axis = 2
AxisRes = 50800.000000
Bottom = -0.950000
Pitch = 0.062500
Tap Complete. Minimium Depth Reached = 0.150000

Attached is a PDF of my Tool Setup screens, and I have attached another copy of the C program that M119 runs.

The printout shows the depth reached = 0.15 (Retract)

Which would be the case if Zmin = Z0 (never went below the starting point).

Which would indicate the Tap cycle ended immediately.

What is the state of your ESTOP input BIT 139?  If it were 0 it would cause an immediate exit.

You might change the C Program to print a message if it exits in the case of detecting ESTOP. 

Change:

if (ESTOPSTATE == 0 && !ReadBit(ESTOP)) Done = 1;        // If e stop triggered, exit loop
if (ESTOPSTATE == 1 && ReadBit(ESTOP)) Done = 1;        // If e stop triggered, exit loop

to

if (ReadBit(ESTOP) == ESTOPSTATE)  // If e stop triggered, exit loop
{
    Done = 1;       
    printf("Tap Exit due to EStop\n");
}

It was an E-Stop problem, at the moment I have my E-stop circuit working backwards from what it should be. So run is 0 and Stop is 1 and I missed the "!" in the rigid tapping code.

Thank you very much for the help.

I just need to test it out with a tap rigidly mounted in on some soft material (like wax). But with a floating tap holder its working well.

Thanks again,
Dan

Hi Dan,

Good news and thanks for posting back.
