Parport card, Startech full EPP capable, $15 USD. Replace your serial interface board with something along the lines of a CNC4PC C1G, and wire it direct to your stepper drivers. The C1G isn't all that pricey. And I find its LED tallies are extremely valuable debugging tools. Very smallish price to multiply the capabilities of the machine by a relatively large figure. > Le 19/12/2013 18:40, ad...@mmri.us a écrit : > > I have been using Linux since 1997, so you preach to the converted. > > Unfortunately EMC does not work wioth Isel G-code at all. > > > > The machine communicates through a serail port not parallel. > > > > Unless some advances occurred with EMC the last past years that will > > drive the Isel it would be worth trying it again, but it never worked > > previous years. > > If all else fails I just have to write an interface myself. > > > > Gene Heskett wrote: > >> On Wednesday 18 December 2013 23:18:21 ad...@mmri.us did opine: > >>> I have a small Davinci CNC that I bought years ago for prototyping, > >>> but never used as my larger CNC gets all the work. > >>> > >>> On Page 47 and 48 of the manual in the link below, it describes the > >>> Gcode for Arcs. > >>> My machine cuts arcs in the X-Y plane but will not move e.g. in an > >>> arc whenever the Z-axis is involved. > >>> > >>> I need an arc in the Z-axis as I want to cut a concave cavity along > >>> the length of a block. > >>> > >>> I tried everything according to the manual, but it refuses to move > >>> in an arc in the X-Z or Y-Z axis. > >>> > >>> Any clue why it does not work with this machine? > >>> > >>> If the link below on Pages 47 and 48 are examples which are trivial > >>> to follow.
