AW SHUCKS PAW, Can't ya just help me??     Attaboy POP stand your ground. You are correct it IS his job.  When my kids were growing up it was HARD to resist helping them out, ALL the way into college for their masters   

I will look for the Mcode, (;-)TP

MACH TOOL BOX / Wizard to integrate DeskEngrave to Mach3 via a wizard

« on: May 11, 2015, 07:10:10 PM »

Here is a Wizard that CALLS Deck Engrave fro inside of Mach3. When called you can create a Gcode file from any TTF font on you system after you save it will auto load the File into Mach3 for you to work with.

You must have DeskEngrave for this to work and you must save the gcode file to the Mach3 Gcode Directory.

To install Unzip the file and copy the directory to the Mach3\addons directory

I think somewhere I have a canned Mcode that uses the Mach3 G12/13 to do circular pocketing. I can look if you are interested.

As long as it works for you is all that matters (;-).

I would simply turn OFF the use rpm for speed setting and do everything manually. Check the RPM with the Tach and set the program to run at that speed. THEN check the cut  thread pitch.

I would not trust the blinky led for anything important other than the switch comes on and off. At speed you will never see all the blinks.  Also your on period for the  signal may be too short and it misses signals at speed. The USE of debounce only makes this worse. IF your signal was clean you should never have to use debounce.


There are only 2 things that effect the outcome of your threads  Z axis moving the correct amount and true spindle rpm. Double check the Z calibration of steps per. Double check the calibration of your spindle RPM.

AND don't ASSUME anything.

Just some thoughts , (;-) TP

Consider this. What you are doing is a very repetitive task. Raise the saw push the stock lower the saw. Repeat a number of times.

This is the perfect situation for a simple SUB program with #vars to drive the cut lengths. That way it is completely programable on the fly.

The number of SUB loops equals the number of parts to cut.

To load the SUB code on startup you can use a MCODE in the init string to load the  cutting  program on startup of Mach3




Is the RPM adjustable on the saw ??  IF not why the value ?

Instead of trying to calculate all the cut lengths and worrying about the over/under run of the stock feeder simple program the infeed of the stock to the Cut length each time. For example make a cut then push the stock the proper distance lock it up and cut. WHILE it is cutting have the feeder  Retract  the proper amount and be ready to Push the stock the proper distance.  Cut then repeat. Don't try to calculate the number of cuts in the 30" travel you have just use the distance of the part length each time it cycles. That way the machine will CUT until it runs out of stock OR the end of the number of SUB cycles you programed(number of parts) is UP and it stops.

IF you are off the length of cut values all you need to do is edit the length value and press an update button and the #vars will be updated and the next cut cycle will cut to the new values. Easy QC on the cut lengths.

IF you have a lot of different parts to do consider USING the tool table to store the cut values in. This gives you 254 different programs you can run and NOT have to hand enter the values each time.

You can have it both ways enter the values for custom setups by hand on screen OR call the tool number and have it update automatically. IF you have a number of different cuts to make on the same stock you can STACK up the jobs by Tool # and it will change its setup on the fly. AND run until it runs OUT of material. IF it does and there is still MORE to cut replace the stock and restart the cutting sequence. IT can  remember where it is in the SUB loop and continue on cutting.

ALL you need for switches is a home for the saw  at the beginning of stroke (saw DOWN on the table = 0.000) and the stock empty switch( eye) for the end of stock.

and a home switch for the feeder. Feeder home is with the feeder closest to the saw blade . That makes all values positve for the saw feed AND the stock feed.

ALSO run it ALL in Incremental mode. That way VALUES do not accumilate and do not have to be divided. Easy peasy.

One other thought is to add G04 P0's in the Gcode mix. THAT WAY there is never any mulitple moves in the Que so Mach3 pretty much is in realtime mode. ANY update will happen on the very next cycle.

Just a thought, (;-) TP

IF Z is accurate that ONLY leaves the RPM to be wrong. You said you checked it with a tach and the 2 were not together on rpm ? I would suspect the index signal card is bad. Could be missing signals OR getting noise.

Pulley RATIO should be at 1:1

NO debounce on the signal. If it needs the debounce then FIX the noise problem with a cap

Try setting the RPM with the Hand tach then cut a thread.

The one canned cycle that you really need, Circular pockets does not exist in mach3.

He could also download a back plotter and practice that way.  Also could be that Haas has a student version control simulator. They are pretty big in the school arena.
