Perhaps now would be a good time to replace the computers ATX power supply and check all the connections.

I think so.
Microstepping does improve the smoothness of operation considerably. I use 1/8th step but 1/16th is rapidly becoming the norm for low cost drivers now.

Another etching, made using the Mach Laser/Impact plugin.
The material is an aluminium surfaced engraving laminate which, fortunately, does not contain any PVC and lasers extremely well.
This is one of my musician buddies, just hope he likes it.

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.

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.
