Show"N"Tell ( Your Machines) / Converting a Chineese Laser to Vector / Mach operation.

« on: October 13, 2009, 05:21:23 AM »

These pictures were sent to me by Mike in Western Australia who has spent many hours converting his Chinese laser from raster to vector operation so it can be used with Mach.
This information will be of help to others who are contemplating the same task and I am sure Mike will be pleased to answer any questions raised.

The output from your parallel port to your controller can be checked quite easily by downloading Fred's port monitor from here:-  http://www.geekhideout.com/parmon.shtml
Pins can be toggled from the monitor and the results should be translated to your machine.

Hope this helps,

Thanks for the link - that looks like a nice piece of kit for the spindle control.

Tangent Corner / Mystery object ?.

« on: October 11, 2009, 10:16:40 AM »

One of my friends is playing a practical joke on me as these things keep turning up in my workshop, I have quite a few now.
Does anyone know what they are or what they are used for ?.
They are made from high tensile steel but that is all I can tell about them. Help urgently needed on this one please.

These are my first thoughts on the control circuit for the laser tube.
May be changed a bit after I have thought it through but looks good for now.

The water circulating pump has just arrived from China.

This is actually a chemical pump with ceramic shaft and seals with no metallic parts in contact with the fluid flow. It has a continuously rated, 12 volt brush less motor with a life expectancy in excess of 40,000 hours (which should see me out if it is as good as it is claimed).

Update:-
Now that I have had a chance to inspect and test the pump it does contain two stainless steel parts: a wear plate behind the impeller and a spire clip to retain the impeller, both parts are non-magnetic.

For others that follow.
Bart has found the answer to his question:-

The ENGRAVING triggering is output on the DIGITAL TRIGGER pin which you will need to assign to a pin and enable.
