For most or all of the existing cycles, I can see how moving them out to remap would work. They take a bunch of parameters, and a location to do the first cycle at. They then run the cycle at each set of co-ordinates until they receive a G80. Each of the canned cycles needs nothing more than it's parameters, they don't need to know where the next cycle will be run, and the parameters don't change between runs. For G71 it needs to be able to read the entirety of an arbitrary profile - which could be anything from 2 g-code blocks to 5000 (or more) blocks. The profile can be before the G71 cycle command, or after it. The same profile will usually be used at least twice (G71 then G70). To make it even more confusing, the profile could theoretically be after M2/M30 so that it is never accidentally executed. The profile must contain at least 1 G0 or G1 command, with G2/3 needed for any arcs, if I'm reading the remap docs correctly, these would break it out of remapping. In the patches I added code to rs274ngc_pre.cc which does this readahead - and then returns execution back to the same point to actually process the copied blocks, if that section was cleaned up and thoroughly checked all the rest of the cycle code could be done using remapping, but without it (or an equivalent) there doesn't seem to be any way to get the data needed. That said, I'm not exactly familiar with the way remapping has been implemented, so I could be missing a really obvious command Ben ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
