General Mach Discussion / Re: G76 threading issues - any thougts?

« on: April 05, 2013, 03:09:37 PM »

Hi all,
Simon,
please try the following.
note all your settings in mach on a sheet of paper ( or make a screenshot )
delete the old XML's ( or move it to an other place )
reinstall Mach3 ( be sure to do it as recommended )
reboot PC
important: DO NOT load an old profile ( XML)!
There will be a new fresh Turn Profile
DO NOT load an other screenset as the standart  !
type in your settings and test the result.

It looks to me that your XML corrupted the system ( Mach3)
at least it did mine. grrrr

Hood, my apologies.

maybe I had better took my glasses on or learn more English or both. 

be kind.

Hi Guys,
just some thoughts.

i don't think a stalling stepper is the problem since the G Code is stopping at that moment.

As I posted before I did some test ( .062 ) everything is well here.

Some things I found while testing.

The pulse must com in clean and stable. That means the Speed should be as stiff as possible.

The feedrate during threading should be not more then 75% of rapid traverse.

The G0 feedrate will not reach 100% after the G32 command unless there is at least a G4P0 command after G32
this does not affect a successful thread.

Feed Override must be 100% ( feed override is not disabled)

I think the index pulse is not coming in clean or there is a hardware conflict or whatever affect the pulse.

just a thought and may be wrong.

BTW is it possible to stop Mach writing to the LastErrors.txt file at least during threading ?


Regards
Alex

Hi guys,

is there a way to turn it off with M5?

No. ( I think  )

but you can add this to your sequence

If GetOemLED(11)=-1 then

bla bla bla ( your timer addition )

end if

Hi Richpress and  Hood,

I think the easyest way is to use the standart method.
config > ports and pins > spindle setup > uncheck " disable spindle relays " > sign output #1 to #6 as you wish for M3 > output signals  > enable the output you choose >assign port No. and finally pin 8 > save settings

M5 is ready, no changes required.


just a thought.

Just a thought.

4 bit input Brain.
OemTrig10 = low bit
OemTrig13 = high bit

maybe worth a try

Hi Derek,

sounds like your spindlespeed.m1s  macro is corrupted.

standart content is:

rpm = GetRPM()
SetSpinSpeed( rpm )


and it sounds like you inverted a wirering to the  PMDX 107 card .

slider up = more speed

G-Code, CAD, and CAM discussions / Re: G-Code issue - different part than the design?

« on: April 03, 2013, 02:50:38 PM »

Is that " shot " always at the same place or random ?
Is the position in the DRO the same wrong position or is the DRO Position still correct?
If the DRO position is correct and the tool is way off then I think it may be a mechanical problem.
