Hi Greg,

This is a shot in the dark but try adding the following line to your script, just before the Code "G0 Z0.250" line and see if that cures the problem.

By way of an update - I have now tested PicLaser generated GCode with an impact magnet (using exactly the same code I would use with the laser) and the results have been posted in this thread -  http://www.machsupport.com/forum/index.php/topic,20490.msg154622.html#msg154622

Hi CES,

I am pleased to hear that you are on your way. 

Just one note on stepper motors (and other motors for that matter) the copper wire used for the windings is insulated with a lacquer and it's insulating properties can easily be damaged by running them too hot.

Hi Nick,

Thank you for posting the link.

I can never get enough knowledge.

The sort of chips that come off the machine when you produce lots of work. 

Sorry, I have a weird sense of humour. I look forward to seeing some pictures of your machine build and hearing of your progress.

Hi Headscraper,

Perhaps if you attach your code (additional options, choose file - Zip it, if it is a large file) then we could take a look and possibly find the problem.

Hi CES,

In the absence of any stepper motor data and because they were running too hot at 2.5 Amps with the Chinese blue board then a good starting point may be 2 Amps by fitting a 2K ohms 1/4Watt resistor. If the motors still run too hot then reduce the resistance value according to the Gecko Manual.
