Thanks for posting Dan, looks like a useful technique.
I think, as you have found, some practice is required to achieve the best results. I will give it a try and see what happens.

Fredzway has been kind enough to share his design for a Christmas decoration with me and to prove the toolpath I have removed the tool radius offset and laser cut the parts from 2mm Obechi. Fred tells me the halo is made from a part section of brass tube so allowance has been made for this to be fitted.

Nice one fred, good fortune profile cutting the parts.

Tangent Corner / A Fine Mess to get into.

« on: March 22, 2011, 04:17:44 AM »

Just the other day I, inadvertently, ran a Trojan (not as hard to do as one may think) which managed to download to A.N.Other the various site passwords which were stored in my browser. This was a real stupid situation to get into and it was only discovered once I had been banned from visiting one site.

Using an online scanner the Trojan was found in less than ½ hour but it took me almost all of the rest of the day to change my passwords at the various forums and sites I visit.

In retrospect, it pays not to have your browser remember passwords and it is not a bad thing to change passwords on a regular basis.

As T.J. once said “The price of freedom is eternal vigilance”.

You could try reducing your X and Y axis acceleration in motor tuning, this should smooth the sudden steps of the slow moving motor and reduce vibration.

Steve,

As far as I am aware it does not have engraving type single line fonts so, as I said earlier, you would not be able to VCarve you would only be able to profile or pocket route.

Steve,

Cut2D has all the fonts you would need and it will output the GCode direct to Mach if required. It does not VCarve so you would only be able to profile cut or pocket route etc. It uses ramp plunge rather than leadin / leadout so it is more use for woodworking than plasma etc.
You should really try the demo version to make sure it is what you want but IMO it does what it does well and represents good value for money.

Hi Peter,

That would explain it.
