Having sorted the big operational issues on my 130W 1400x900 machine (well at least it’s behaving for now) I am ready to move on to troubleshoot more nuanced tweaking.
When I bought this behemoth I got the most size and power I could afford. Not realizing that the large beam and heavy laser head would not be suitable for the small details I hoped to engrave.
Application: guitar amplifier control panels and logos. No images, just text (as small as 4mm high). Front engrave and also reverse engrave and fill.
Here is a fellow amp guy who is killing it on this stuff:
Turns out though, he cuts the panels on his laser and engraves with a rotary. Regardless, his results are fantastic.
My machine has been riddled with trouble from the first power on. At times when it has operated I’ve attempted engraving, always with the same abysmal results. Just terrible.
Precision has improved with some recent upgrades. A 38mm lens and Light Object power supply made noticeable improvements. I can now fire the tube down to 8-9% power. And, ramp tests show cuts around .5mm wide.
My plan is to focus on speed, power, offset and acceleration. I’m sure I improve the results. But, just to manage my expectations…is it feasible to accomplish precision engraving with this machine? Should I be able to engrave crisp, clean 4mm text? Or, should I abandon this futile pursuit and seek another solution???
Thanks, as always, for any and all advice.
