I press Stop for machine to stop, then press Backward (or Forward) in order to continue cutting. But when press Start for cutting, the portable CNC cutting machine start immediately without repeating the heating and oxygene discharge process in order to piercing. Besides, the height sensing control donot work (we have to up/down torch by manual ).
