In Genconfig what have you got the IJ modes set to, INC or ABS. For most code it uses INC. The POST in Bobcam SHOULD be setting the IJ mode to which ever method the POST USES for IJ mode.

IN the Preamble blocks is there a G91.1 code?

You best be "dodging" that chuck jaw in that photo (;-)

I'll add the button easy enough.  It will ask you HOW FAR TO DODGE. And then write the dodge code OR do the move live depending on the record button's state.


WAIT::::  I already have a function to cover that. Look at teh MOVE TO POSITION section. You input where you want to move to and it will write the code for you to dodge things.

Another clue ? When you load teh Gsim and have teh blank page if you mouse over the screen the toolpathing widow flickers from color to black back to color at the speed ot which you are moving the mouse. It never did that before.

OK a Question about viewing this in gearotic. I select a pulley and apply and it shows the rendering on screen. I then go to the WORKBENCH and I get a blank table. I did select the pulley from the project list.   AM I doing something wrong there as well ?

Latest version, Gearotic motion runs OK, I have rerun the distrrabutables file. Loading the RR.

STILL NOJOY a blank screen. The tool Crib works fine but still no toolpathing.  I even tried rrerunning the GSIM while the GSim was loaded.  Got a LOT of info in teh History file about extents but no toolpathing.

Thread milling   Remember this for a 4th/5th axis turn center not a simple CNC lathe

For large diam threads Thread milling beats single point cutting hands down. Manual TURN machines and simple CNC lathes did single point because they had no other choice.  Your machine has a choice as it is NOT a conventional LATHE.

A single operation.

IF your machine can MILL an accurate circle you can do accurate thread milling. Does not have to be as rigid as you think

Cutter not any more expensive than a carbide boring bar with thread insert.

Can reach just as deep on large holes. Can even use the single point boring bar to do single point thread milling.


As to operators responsibility. All standard threads and profiles are listed in the Machinist Handbook.  All crusty machinists will have a copy(;-). No calculator needed but you WILL have to put your glasses on , at least I do.

Creating the profile for the part to be threaded is normally a seperate operation as it requires different tools.

Before you begin the thread operation reguardless of what method the stock HAS to be the correct size. That way when the threads are cut to spec the profile is correct.  

As to clearance moves a good wizard will let you EDIT the GCODE on the FLY to add such moves. This one does as well  {EDIT GCODE} OR I can add an edit Button that is conversational in nature BUT you still have to be able to tell it WHERE and HOW to dodge the problems. The wizard CANNOT read the part in the Chuck. (well it COULD but (;-))

Rememeber Wizards are conversational AIDS to programming NOT a robotic programmer of parts(;-).

Just a thought, (;-)

OK so I can't tell an A from a B. Try this one.

The tool Button works it brings up teh tool Crib.

But the reset button this time crashed.

Why is it when Mach4 crashes you cannot CLOSE IT DOWN from task manager. You always have to reboot the PC and I mean power it down the restart???

To start teh spindle and set the speed.

M3 S100

Do you have an empty drive on the 540 ? If so that is where you set the Port and pins to to run the stepper for the spindle.

If you are only running 3 drives and have an empty slot add in the extra drive and mapp the signals to that slot. If all your drives are already used then add a 2nd LPT card and run the spindle drive from there.
