Show"N"Tell ( What you have made with your CNC machine.) / Re: 1/5th Scale V8 Blown

Beautiful work Steve.

I had been puzzling about the setup for machining the offset cranks but now you mention the 5 centres it all seems so obvious.

I start with the AC in and it reads 122v then I measure the output of the transformer I get xxv dc and when I switch it over to AC I get 53v so it makes me think did I buy a AC transformer instead of a DC transformer? Then I measure at the capacitor and I get 73v DC and then I try AC and I get 154v.

I am assuming you do have a full wave bridge rectifier between your transformer output and the capacitor ?

Excellent work Hood - that tool-changer certainly is slick.

Just a guess but I would suspect an electrical spike (noise) is being created when your torch fires and this is upsetting your PC.

Try disconnecting the torch and THC then running your GCode again to see if the problem persists.

You could certainly do it without the laser pointer and just by using the tool point if you wish.

Only linear distortion (scale) is easily catered for at run-time.

A visual location method and local system rotate was discussed in a earlier thread http://www.machsupport.com/forum/index.php/topic,22932.0.html
It is not difficult nor expensive to implement.

Tangent Corner / Re: Mist coolant

I don't need a large volume of coolant mist spray so I use one of the simple inline oilers that are used with air tools.

Sounds as though you may have turned off the Jog ON/OFF button on the main screen (It should have a green border to enable keyboard jogging).
