Plasma table ohmic sensing
« on: October 19, 2012, 05:15:40 PM »
I have Diy plasma table with capacitive sensor. Main problem is when machine is cutting on sensor ring is sticking dross, so i have to stop the cutting process and clean sensor ring just because sensing is not working precise or not workin at all.
Is very annoying when i have to cut thicker sheets because i have to clean sensor ring more often.
Can anyone build his own ohmic sensing?
If yes can share informations?
