darcshadow 1,625 Posted March 21, 2018 Another topic talking where the posters cutting head is not working got me wondering about cutting pressure. My understanding is a solenoid moves the cutter up and down, in my case it pulls the cutter up and gravity pulls it down. Since solenoids are pretty much an on/off thing, how does the machine change the pressure of the cutting head on the vinyl? I mean, mechanically what is changing?

Dakotagrafx 7,297 Posted March 21, 2018 solenoids are electro magnets - more power to them more down force applied. I knew 2 years of tv repair classes would come in handy 40 years later - no tv's didn't have solenoids but it was part of the class on electonics and the 2 of us that took that part kind of showed off and did the modules for all 3 of the sections of the class and passed them all. think it was bianary, tv and communications - yeah I was always second to my best friend that it came natural to :/ Share this post Link to post Share on other sites
bikemike 711 Posted March 21, 2018 IMO, current does both. Increased current in the down direction increases down force. Share this post Link to post Share on other sites
darcshadow 1,625 Posted March 21, 2018 Duh, ok, makes sense. My experience with solenoids have always been an on/off or extend/retract thing. Didn't think about varying the power to them. Share this post Link to post Share on other sites
