I have 2x K40s, from different vendors, so they are a bit different (both digitals)
Both have the same time (1 month), and the same working hours. Both have been using always at 30% power, and both at the same time.
But one of them has stopped cutting, as it has a very low power. Have tried to cut at 30%, 50% and even 80% power (just a tiny 10mm x 10mm box), and I always get the “same” depth: just like engraving.
What should I check?
Also, I have ordered 2x MiniGerbil, that will be here this monday I guess. Should I install it before making further tests?
PS: due to strange circunstances, I can not contact or get help from vendor: he sent me it by error and I ended paying just 100€ for it.
