    To be fair that’s actually the safer way to send it, what they should do is put a big label on it saying set for 220v , if they set it 110 and someone plugs it in then ‘bang’ , set it to 220v and it...

    Are you just taking the laser part out and sending that back ? Or is the whole machine going back ? Very unusual to get a faulty laser , much more likely to be cabling or psu problem (but not...

    Don’t forget wavelength as well Dave , all thing equal (which I know they are not) the co2 laser will always have a much larger spot than a fibre just because of the wavelength, the lower the...

    I’ve got one , made it myself, I fitted the biggest galvos and biggest beam expander I could get which should give the smallest spot size, it’s ok for some jobs but our Chinese gantry laser gets much...

    Yeap , we are at about 85% now , some still use cheques and it’s a right PITA , I guess it gives them a few extra days of positive cash flow and there’s always a chance you could forget to cash it

    I would say it either a connection to your galvo head or more likely a faulty galvo head, either way it’s going to need some level of taking apart and fixing , expect stalling tactics from China and...

    1000 Dpi is 0.0254mm that's quite a bit smaller that the beam size of a co2 laser so you will be doing a fair bit of overscanning , so the quality is probably better but not for the reason you would...

    I've made pcb with the fiber , you only need to cut around the track , as mentioned fibre is not great on copper, I always use the yag or 50w fibre , and cut at least a 0.3mm gap around the tracks
