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.

Thanks guys.

As soon as our friend writes "PicTattoo" the Parlor will be up and running.

I can't help asking....

Why would you ever consider operating a machine or using Mach3 with the excellent educational tool 'Raspberry Pi' ??

We always reference after power down at work, its a habit I'm not keen to break, so my home machine I intend to reference every day too.

There is no problem with that, just remember to do it again when you start up if you need to rely on the reference position.

Hi Steve,

That's a strange one - I use numerous SSR's on my machine without any problem.

I presume you measured the voltage at 5.22V with the SSR connected ?? if that is the case then check that your GND return, from the SSR, is connected to the correct point.
