Retired machinist, tool & die, CNC prog & op.
Started 3D printing after son gave me his geeetech A20M which I fully upgraded. Then had problems with hotend not keeping the correct temp. Even though I changed the whole hotend and thermistors (different temps with each change) still had problems. Started learning the Marlin OS so I can make a new temp-chart. So I bought the X1C & WOW what a difference. Now the real fun begins.
