Yep - always been like that, and perfectly workable. Pretty logical that if you turn something off after feedhold, you probably need to turn it back on again before restarting <G>. Feedhold itself should simply stop machine movement in a controlled manner and nothing more. Depending on how OEM or installer has set up defaults. when you switch to jog, the spindle may or may not stop automatically, but it's up to the op to make sure the start position is safe. Don't press reset unless you want it to behave like EMC ;) All they have done different with the 30 series that sales article applies to is add a screen and make approach move "easier" ??? by making it programmable, but all the controls I've used leave it up to the operator to ensure the return move to last position is safe, and that screen is NO different, still up to the Op, it probably belongs in the bell and whistle category. Easier IMO to jog somewhere safe, rather than try and guess with MDI or a series of editable moves. Normal scenario is to jog to very near to where you feed held, restart the spindle/coolant, then resume. >ok some of the above you would hope the operator knew what he was doing >and would pick a "safe" restart point get machine ready to restart in >away but never is the case with such a restart i would feel. its all >swings and roundabouts i feel(if so why the above restart type?) Never is the case?? IF you pick a sensible start point it works fine every time. There are some limitations to commercial feedhold and restarts but it's up to the Op to understand these. You can never cater for the actions of the foolhardy or ignorant but that shouldn't hamper sensible development because it "might be dangerous" - so's crossing the road. Feedhold wont work during threading/tapping cycles and with some controls during subroutines, also depending on the type of move in operation it may not stop until the end of the block. RTM and know the limitations and it's perfectly safe and usable.
