These little insects were laser cut in wood from the .dxf files posted in Dave’s thread where he cut the excellent aluminium butterfly. http://www.machsupport.com/forum/index.php/topic,15111.0.html

Hi Todd,

The MechMate is probably the most substantial of the large scale home build machines and there is some constructional details which should give you an idea of material sizes here http://www.machsupport.com/forum/index.php/topic,15663.0.html
There is also much information on the MechMate forum (you may have to register to access).

If the steppers are Sanyo 8 wire then this information should help you with identifying the connections http://www.piclist.com/techref/io/stepper/wires.htm

There are many variants of the yuk board instructions but these are probably the best http://www.savebase.com/infobase/downloads/TB6560/TB6560_4Axis_Driver.doc

Hope this helps.

General Mach Discussion / Re: Please Help: 3 MM error on X axis

« on: September 01, 2011, 01:59:23 AM »

Have you checked for loose mechanical parts which are causing backlash ?? - is there any slack in the axis ??
Have you checked that your steps per unit are correct for that axis ??

Just a couple of suggestions.

Thanks for the heads up on fotosketcher, always nice to have new tools.

Especially FREE tools   

There are many different types of art and I am not sure if this qualifies or not. It is a computer generated "etch-a sketch" saved as a .dxf then as GCode. I must admit that I have seen better laser engravings but as I am in no way "artistic" this is perhaps a start.

Daus,

Some motherboards with on-board graphics work just fine whilst others do not. In my case fitting a PCI (or was it AGP, can't remember now) graphic card resolved the issue. If possible, borrow a graphics card just to try.

When using the Impact / Laser Engraving plugin, I have found that the initial preparation of the image or photo is key to success. A free program which has just come to my attention is FotoSketcher by David Thoiron. http://www.fotosketcher.com/download.htm
(When installing use the advanced options unless you want to install the unwanted toolbars etc or else download the portable version).
This program is capable of producing some quite stunning results and in some ways can be better than the Photochop plugin I have been using to date.

Are you perhaps using a laptop or computer with on-board graphics ??
