Laser not cutting

Hi,

I have recently retrofitted my 500x350 70w yueming laser cutter with the x7 dsp, new 80-100w 220v powersupply and stepper drivers. I am really happy with the dsp, it was really easy to wire up and i managed to get all axis calibrated and moving with no problems.
I have just wired up the laser tube to the power supply with current meter, double checked all connections and fired it up.
The problem is I cannot seem to get the laser to cut through material, it will engrave and i have managed about 1mm deep in mdf, but last year before i changed the power supply and dsp i had no problems cutting(apart from terrible software!)
I have checked alignment, it seems pretty good. The laser tube lights up white, not sure if this is a good sign or not.
Does anyone have any idea if the tube is on its way out?

The laser cutter has a 70w sticker on the front, the tube says c02 c-1200mm
GDA4713 and is about 50mm diameter.

I think your tube is at its end.. You need to replace it if you will see a plasma but have no power..
Clean it up and sell it to a tubecollector..
