General Mach Discussion / Re: Axis Stops Working

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.

Hi Dave,

Yes it's pretty easy to do.
As an example if the spindle control is configured to output#1 the the F5 key will toggle your relay on and off.
Easy enough to change this, just experiment a bit and you will get the hang of it.

Mach SDK plugin questions and answers. / Re: Impact engraving plugin

« on: May 11, 2011, 11:24:55 AM »

Hi Stitos,

Interesting one this.
I just ran two examples at the same power settings etc. The top one with 40uS unchecked and the lower one with 40uS checked and I was going to say that there is no difference between the two - until I saw the photo which does reveal a slight difference (the top one being better, perhaps).
I will investigate this further and see if I get a difference with other work.

(please excuse typo in earlier post 40mS should read 40uS)

General Mach Discussion / Re: How can I configure Mach3 for motor enable with step??

« on: May 11, 2011, 10:56:30 AM »

Tom's excellent work should not be dismissed but control has moved on leaps and bounds with the introduction of cheap stepper motor controller chips from, for example, Toshiba et al.
These chips can incorporate microstepping, automatic current reduction when idle and provision to combat mid band resonance amongst many other refinements over the basic, home constructed driver using discrete components.
It may even be cheaper to purchase the TB6560 and associated components, copy Toshiba's recommended circuit and build your own controller that way. Alternately the multi axis imported boards from China which use the TB6560's may be an even better solution.

If you have ever seen the difference between a stepper controller operating in full or half step mode compared with a stepper motor operating in 1/8th step mode you will know exactly what I mean.

As far as I am aware it is the length of the impulse on the digital trigger with 40uS for laser and 10uS for magnet.
I have only ever used the 40mS setting.

Anybody else have any more info on this ?

I would be relatively easy to do this externally to Mach with one TTL gate and a couple of components but……….

Imagine cutting a near horizontal line which may have 100,000 horizontal step pulses but only 2 vertical step pulses. If the federate was slow the vertical step pulses may only occur every 5 seconds or so.
What sort of time frame would you choose to say that the vertical axis was inactive so it is OK to release the enable signal ?

Perhaps if you could give us some more detail of the reason or application for this a reasonable solution could be found.
