I am sure it is possible but it is not something I have ever tried.
I suspect that the final result would be far from satisfactory as there is bound to be some scorching / charring of the edges of the topcoat and the entire surface (and quite possibly the entire thickness) of the undercoat.
Perhaps a subject for experimentation ?

You will need (single slot) sensor feedback from the spindle for the Auto Calibrate function.

Also stepper and everything else works just fine.

Maybe, but don't count on it.

With the passage of time the location of links inevitably change. This should be a current location;

Hi Flo,

Mach3 using the Parallel Port is a combination that is not recommended / intended to be used with a laptop. You may get away with it but you will always encounter problems of one sort or another and this spindle issue may just be one of them.
Either, use a dedicated PC or an external motion controller with your laptop but they must be dedicated computers and not connected to the internet / receiving updates etc.

Klaus was working on a new version last time I looked, perhaps check out his website http://www.kd-dietz.com/klausphp/pages/ger/plugins/webcam/description/wcam_description.html

VB and the development of wizards / Re: M10P1 NOT WORK USB MOTION CARD :o

Hi Vogavt,

Within Mach3, running a macro or calling an M3/M5 takes some 100mS of time to complete and thus causes unwanted laser burn at the start or end of an engraved line. Because Mach3 blends axis moves then the TTL level of the A (or B or C) axis direction pin can be changed at the exact instant (or al least within 2mS) the X,Y or Z axis start to move. This principle is demonstrated in the linked video (although this one was made in the early days of Mach4 when there was still some confusion between Imperial and Metric units for the A axis).

https://www.flickr.com/photos/tweakie-cnc/27822699768/in/dateposted/

I have attached my Gcode for a similar part (another Mach4 test). Here the A axis direction pin toggles when the A axis moves between 0 and 0.01. Although the code was produced for Mach4 it will operate perfectly with Mach3.

My laser switches ON when its trigger input is TTL(low) and OFF when the trigger input is TTL(high) so within Mach3 the Active Low state of my A ( or B) axis direction pin would be set to switch my laser accordingly.

(There are some safety concerns when using an axis direction pin (because a Direction pin TTL level is modal and the laser could be left ON when in EStop) so certain precautions have to be taken).

Hope this makes sense.

General Mach Discussion / Re: MACH3 fails after some updates of win7

« on: May 02, 2018, 11:39:04 AM »

Your machine PC needs to be a 'dedicated machine PC' which is not connected to the internet, does not run other software in the background and does not receive updates.

Hi Cncman,

Did you remove the offending update (as TPS linked) from your Win7 installation ?
