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

Tweakie thanks,
but when i am reducing to 5000mm/min the laser doesnt fire!

Just a thought but it may be worth looking at the electronics train (TTL) to improve the voltage that you get at the laser input. IMO the laser should be triggering OK at 5,000 mm/min (mine triggers down to 3,000 mm/min). If you can get this sorted then I am reasonably confident that the double image problem will be cured and you can return to the 70,000 speed without issue.

Great idea. Did you spring load the marker of just rely on the give in the tip ?

Perhaps a Logo next ?

I know that a Permanent Marker would have been just fine but it is these little things that earn me Brownie Points.

ntlaser,

Looking at your Micken Mouse, the double image is not linear and this suggests to me that there could be a delay between the Mach digital trigger pulse being sent and the laser actually firing. Maybe that reducing your feedrate to something around 4 to 5 thousand mm/minute may produce different results.

Yep, plenty of castor fumes and how about the tethered car racing ?
We could start another thread on this. I think Eddie Keil died a while back but Keil Kraft were located in Wickford, not far away from where I live now. Most of my buddies buy the artf planes and as you say, few build their own from scratch now.

Getting back to lasers, have you seen the Z axis table mechanisms that Bart has used for his machines ? http://www.buildlog.net simple yet effective.

Rich,

What CAD do you use to get your .dxf to import to LC  ?

One more of these, just to bore those that I haven't already bored to death.

I fly the hard hat stuff (pylon racers) for a few months of the summer but I just love to watch the free-flight at Old Warden, Bedfordshire. If you ever share any of your free-flight designs I would be very interested to build.
