Show"N"Tell ( What you have made with your CNC machine.) / DB25 to DB25.

Sometimes I find it necessary to intercept signals on my Parallel Port cable in order carry out some external processing, such as delaying a signal or extending a pulse width etc.
In the past it has been convenient to use one of the ready made, inline RS232 testers (removing the internal resistors and LED’s) then making breaks in the appropriate tracks and connecting my external circuit to the appropriate pins. Constantly changing technology has now made these RS232 testers harder to obtain so I needed to create an alternative.

Routing a strip of double sided PCB with the required pin spacing (ready made strip board is of little use here as the DB25 pin spacing is rather odd and they are staggered between the rows) then cutting off the required length and soldering on a DB25 plug and a DB25 socket produced exactly what was required.

Strange it should just start to happen.

Have you added any new hardware / software relating to the machine ?
Have you made any changes to the wiring (route etc.) ?
Have you made any other changes to the machine ?

As more people are trying this CNC pyro-engraving and experimenting with different heated wire designs, the results are continually improving.

This is one of the latest images to be posted.

Yep, we've actually been trying to come up with something "witty" to do on the opposite side as it looks unbalanced now

How about cooking time versus beer consumed ?

There is a little bit of confusion with terms (as we think of ATC as being Auto Tool Changer) but the Vectric ATC (Arc Tangent Curves) post processor is what you need to select when generating the GCode within VCarvePro if you don't want arcs.

Hi Guys,

This thread also relates to the same problem http://www.machsupport.com/forum/index.php/topic,24665.0.htm
To my knowledge, the cause has not yet been proven as to being an SS or Mach3 issue.

Nice work Dave. 

A couple of cans of Bud and some of the 160 deg. stuff would go down well here at the moment (Glastonbury).

From what you describe, my guess is that you have a corrupt .xml.

If I am right (50/50 chance)...

You could either create a new profile (not as a clone of the original) and configure it (port & Pins etc.) from scratch.
or
Look in your Mach3 xmlbackups folder and choose a fairly recent (before the problem was noticed) one from there ( copy it, rename it to [your profile].xml and copy it into the Mach3 folder - backup your existing [your profile].xml from the Mach3 folder first, just to be safe)

Hi John,

Thanks, that is a very good suggestion and something I will look into.
Basically, my initial thoughts are that for diode laser operation (slower feed-rate) changing the calculation ratio between output power (amount of ‘dot-gain’) and feed-rate will achieve the desired result (a bit like the way in which the ‘greyscale compression’ function currently works for the CO2 laser). Anyway this is something I will investigate, as time permits and report back.
