GraverMax hand engraving unit, the machine was working fine until the foot pedal failed, and then it was stored away, I just pulled it back out and the power on works, and the speed dial works, however the PSI never increases and so the engraving tool never reciprocates, the pedal needs repair or to be replaced. I can't say that's all it needs but most likely that should fix it.
