I have noticed that there is a change in working diameter during the return stroke of G76, and also that the return strokes are at different radii.
Shouldn't all return strokes be along the notional "drive line" as suggested in this forum thread? http://www.linuxcnc.org/component/option,com_kunena/Itemid,20/func,view/catid,20/id,5023/limit,6/limitstart,6/lang,english/#13450 As he points out, it isn't important in the case of external threading, but can be troublesome if you are internal threading with limited clearance at the back of the tool. The behaviour seems to be encoded in interp_convert.cc, lines 4365-4366 and 4399-4400. If safe_x is safe, why add/subtract anything from it, why not just move back to it, and retract? I think this might also explain the rather worrying little "wiggle" at the beginning of a threading cycle. -- atp "Torque wrenches are for the obedience of fools and the guidance of wise men" ------------------------------------------------------------------------------ All the data continuously generated in your IT infrastructure contains a definitive record of customers, application performance, security threats, fraudulent activity and more.
