Good news (at last)

With the breakout board powered by a little 9v battery, I have just managed to make 20 test cuts in a row without the slightest hint of a glitch. These were a mess of 20mm circles and straight gashes across the now perforated sheet which is pretty tough as it causes the pilot to reignite in each gap.

I think that pretty much 100% rules out inducted and radiated interference and leaves power-line transmitted muck to deal with.

Bear in mind that these tests were carried out with the cabinet door open and the battery dangling outside it.


The next set of questions are,

1 - what PSU do I build/buy/rob ?

2 - I have some small transformers, bridge rectifiers and various capacitors here so should i just go basic transformer-bridge-cap-board or more complicated?

3 - the cabinet also houses the PSU for the motors and a small one for the control circuit relays, should i filter the incoming supply to the whole cabinet OR just to the board supply?

I'm getting close now, just a little more to sort.
