simulation

My Fanuc 21TB lathe has both 'dryrun' and simulation features.  They are not the same thing on this particular control (Emco)

• Dryrun
  • Is a 'mode'. i.e. select dryrun button and then cycle start/stop/FH as usual.
  • Moves the machine axes along the program path
  • At a 'dryrun' feedrate - which is not the FR in the program - set as a parameter somewhere backstage
  • Is intended to be used without material in spindle
  • Spindle does not rotate during dryrun
    • Collet/chuck missing material alarm is suppressed during dryrun
  • Single-block mode & block-skip are both available when in dryrun mode.
• Simulation
  • Is a 2D graphical simulation of the toolpath(s)
    • toolpaths are drawn on the screen at programmed FR using the tool control point
  • Similar to LCNC's feature of keying through the gcode file and watching the backplot progress... except it's animated at program feedrate.
  • No machine movement
  • Normal machine controls are not used to start/stop/pause the display; there are cycle start/stop softkeys displayed while the "GRAPH" screen is active.

So having said that, is the 'dryrun' branch/feature (not-yet-added to LCNC) a simulation or a 'dryrun' with machine movement?  I've been unable to find anything on GH.

To clarify - I can't find anything on GitHub as the links earlier in the thread are dead, and a search for 'dryrun' in GH doesn't come up with anything.

from what I know dryrun was a function implemented by the "legendary" dgarret ... who however left nothing of his "dev" repos except what was already implemented in master (switchkins for example, or adaptive-feed). ...now unfortunately, at the time I was intrigued...but I didn't clone the repositories...so that apparently got lost. It's been a long time... I don't know if I downloaded it... if I found it I could make it available... but I'm not sure if dgarrett appreciates it... it would be nice if he had his say......

At least think is only necessary make a sim encoder for every joint and switch feedback signal with simulated one .... obviusly need to switch from sim.ini to real.ini with button or somethings of similar....

I haven't reread the thread but if I remember correctly it would let you run your gcode without machine movement.
