General Mach Discussion / Re: Dpad interface questions.

« on: September 08, 2006, 01:51:19 PM »

TO Art

I found the keyscan codes for the above functions.  estop=192,  jogs speed - = 112, jog speed + = 111.
How can i get these into Key Grabber.  It appears to be looking for a Keypress and will not let me do manual entry.
Is there a workaround.  Sorry to be a problem but i'm learneing a lot.

General Mach Discussion / Dpad interface questions.

« on: September 07, 2006, 06:25:01 PM »

Iinstalled a Dpad (cheap wired type) on my Mach3 machine for jogging table and Z.
that part was easy with Keygrabber since they are specific keys.

I would like to program the following functions into this dpad, can someone tell me the Key sequence to
JOG speed +
Jog speed -
E stop

General Mach Discussion / Optical limit switch question

« on: September 05, 2006, 04:43:58 PM »

I want to use slotted optical limit switches on my little Sherine.
Plan is to mount sensors fix with slot open when machine in the clear, break slot when limit is hit.
I plan to pull input to 5v with the recommended 470 ohm resistor.

Looking at physical limit arrangements i think i should feed each sensor into an AND circuit.
Limit is high if slot is clear on both +limit "AND" -limit.
Am I correct.

General Mach Discussion / Re: Still do not understand "GO TO" button operation

YA know i looked at that button a hundred times and always saw "go to" not "to go".
Once your rmind is made up do not try to confuse it with facts.

Now that I feel reallly stupid what are the chances of easily getting a function like I talked about.
Is there one of the wizards that will help me.  just a simple "go to" since hand cragks are hard to turn with power on the stepping motors.

actually using 3 flute (purchased form sherline).  don't know the speed. but usually run about as fast as i can without melting plastic.  for nice clean edges smooth up with scotchbrte then fire polish with a propane torch.  Gives a nice edge. Practice a few times cause it's easy to melt with that much heat.  Kinda like spary painting pass the torch over the edge serveal times until you get what you want don't hold there.

General Mach Discussion / Still do not understand "GO TO" button operation

« on: September 03, 2006, 09:51:29 AM »

Guys I’m still having problems making the ‘GO TO” button operate in a consistent manner.  I obviously don’t understand how it is supposed to work.
What I thought should happen is it would work to go to any position desired (like a G0 x?? y??).  What if tried is as follows.

Zero all axis using “GO To Z”
Press “GO TO” it starts flashing.
Input  on X axis 1.000”.
Hit enter X axis reads 0.000”
Press “GO TO” it stops flashing.
X Axis now reads 1.000”but does not move.

What am I doing wrong.
I would think is would be 

Zero all axis using “GO To Z”
Press “GO TO” it starts flashing.
Input  on X axis 1.000”.
*** Hit enter X axis reads 1.000”
Press “GO TO” it stops flashing.
*** X Axis moves to 1.000”.

Again What am I doing wrong.
feeling pretty stupid abuut now

General Mach Discussion / Need help to on "GO TO"

« on: August 05, 2006, 09:31:42 PM »

How does the "GO TO" button on the "Program Run" screen work.
I appears that it changes the coordinate system referenced to the tooling position. 
Is that true.
