Thanks Spruft.
If that was a good use of the laser then this has got to be the daftest - my own personal Grain of Rice.

For others that follow....

The trigger pulse width (digital trigger) will vary dependant on kernel speed.

It is 40uS at a kernel speed of 25kHz
      30uS @ 35kHz
      20uS @ 45kHz
      10uS @ 100kHz

But this goes totally to pot if you select Sherline 1/2 pulse mode

BB,

I don't think there is an easy way.
You need to experiment with velocity and acceleration settings in motor tuning as well as your feedrates in the GCode.
You should be able to find a point where constant velocity just rounds the corners a little but the speed reduction is not too great. Everything is a compromise.
Keep us posted on your progress (I haven't really tried cutting balsa wood yet as I always seem to buy ARTF nowadays).

Neat idea using the RC fuel filter in your air assist feed.

This was perhaps a trick of the light or camera function but from more tests carried out I can safely say that ( for my setup and triggering circuit ) it makes no difference at all if 40uS is checked or not, the end results are the same.

Perhaps a fresh install of Mach may be the first thing to try.
Initially just try re-installing over the top of the existing version and if that does not cure it then uninstall, delete all traces, having made backup copies of you license .dat and .xml files etc. then a fresh install.
That's what I would try.

Something that would perhaps be nice, although it may mean a lot of work, is to have a ‘Verified Member’ symbol (for those that have applied for it) to show that a member of this forum does indeed have a genuine Mach3 licence.
I agree with Rich and I am very happy to help those newcomers who are using the trial version or indeed a licensed version but there are far too many Ivan’s and Papa’s for my liking.

That is brilliant Steve just brilliant.

One question I have concerning your cast iron piston rings - The bore and OD were turned, they were parted off then they were placed on a mandrel and heat treated but how did you make the split in the rings (O into a C) please ?

Going off on one.

Although we have all, probably, used pirate software at some time or another (and I must hold my hand up to using a time limited trial beyond it’s 30 day limit by winding the clock back) I really do despise software piracy and condemn it’s use.
It appears that there has been an increase in the number of pirate copies of Mach recently and since the release of a Mach licence file generator the illegal copies are impossible to distinguish from ones that are genuine. Perhaps version 4 will address this issue but that would almost certainly be underestimating the cunning of the crackers.
Vectric, who produce an excellent range of software have now been targeted by the cracking teams making their flagship Aspire v3 the most widely ripped off software currently in the CNC world. Unable to get a perfect working model from the demo version a cracking team advertised for contributors and within a few weeks obtained enough $$ to purchase the full version of the software. The complete cracked version appeared a few weeks later.
When I see new members of both this forum and the Zone who are unable to set up their own machines but are using Aspire v3 then I wonder – Did they really pay $2,000 for it.

Sorry to moan but I just felt it coming on.
