Well here it is my first few cuts with the j48-1. Pretty impressed so far. I can't run it for long as I still have cooling and extraction to sort out, but the laser seems to cut well and marks anodised aluminium well too! Happy :)
Fitted the ULO optics mount ready to take the head. I found ULO optics to be much cheaper than the Synrad options I was looking at. I got the compact laser mount (C-LMC), and the compact lens nozzle assembly 38mm F.L. (C-LN38) Both for £300+VAT which is less than half the price of the Synrad setup.
