Show"N"Tell ( What you have made with your CNC machine.) / GUN SIGHT TOOL

« on: July 16, 2017, 09:38:28 AM »

Finally made a universal gun sight tool. Still need to do a few tweaks and make some things for it.
It's robust and calculations done to confirm what was done. Not too much CNC was required.

Gaute,
1.Post the xml file you are using for the lathe.
2.Post the manual for the usb driver board.
  Mach 3 reads spindle rpm in real time based on the index pulse and that input is used for threading and shown in the DRO.
  
  So ask the seller these questions:
  ? Does the driver board support Mach3 threading?
  ? What exactly is represented by that output from the card?
NOTE: I personaly will not provide support for a Chinese card that lacks information relative to Mach3.

I have a standard breakout card that I can connect to the computer LPT port, can I use this in addition to the USB (of cause it must handle index) or should I just buy a USB smooth stepper card?

 
In past topics you said you got / had a SmoothStepper.
If you are, then use the Warp9 Site for info on that card and plugin. I have not kept current
on the SmoothStepper.

As far as using the lpt port and the usb driver / breakout board.......
Can't specifically answer if that will work.
The usb is providing control of the steppers based on Mach3 instructions. Threading is an internal
function of Mach3. That usb may not know what to do with the instructions given with that
combination. That is why external motion control is given to an external card like the SmoothStepper.

You only use a ONE SLOT of the disk, timing / use of a multi slotted disc is not supported ( page 42, 43 in the writeup ) and don't enable  any turn diagnostics. Just put some black tape over the other three slots so the sensor will not see them.

G76 X15 Z10 Q1 P1 J0.006 L45 H0.3 I29 C0.025 B0.0001 T0

So your putting an M6-1 thread on a 15 diameter stock.

? Z10  You realise that normaly one would thread towards the chuck
  so Z-10 and NOT Z10.? Note also that the there should be a move
  of 3 to 5 P ( or greater) before the actual start of the threading
  as this give time for the axis to accelerate. You should also check
  the feedrate in the wizard so that chosen feedrate is acceptable.  

? H.3 I would suggest a smaller first pass depth

? C.025 Why so small?

? B.0001  Practicaly speaking, doubt that your lathe accomplish that.
          B is optional....

Are you using a SmoothStepper? It would control the threading.

? M03 S300 You need to set spindle speed manualy and based on the index
           pulse signal.See the Threading Write up.

If Mach3 sees no index pulse there will be no threading ie; changing from G94 to G95. Note that threading will not start
until the index debounce is satisfied ( needs to see so manny index pulses before it accepts the signal).

Do have an index configured for the rpm?
Are you using a licensed version of Mach?

Maybe have a read of Threading On The Lathe which can be found in Member's Doc's.

Interesting approach and can be tailored to a number of things.
I also would be interested in fooling with it if you share it.

Bravo1,
Smallest drill size I have touched off was an #87 (.010), but, as you say your going down approx.  1/2 of a  #97 (.006").
Hmm...... 0.1mm is just a human hair in diameter at .004" so understand your concern.

Curious, what are you drilling and what federate and  rpm are you using?
Are you using cnc to peck drill with that size?
Use Mascot drills?

Attach your xml file that you are using. IE; Mach3Mill.xml
It can be found in the directory where Mach3 was installed.
Copy and rename it to a unique name like carob.xml before posting it.
