Cannot explain ferror? CNC hobbing machine

take raw encoder counts as an input (S32) and internally promote that to S64, which can never wrap. Then calculate the workpiece position required from that in double-precision float.

Please explain how to do that? Or please direct me to documentation explaining how to do this? I'm busy learning more about components. (I've always only used ladder, and am now learning about components - I've always brushed it aside as it seemed complicated, but see the advantage.)

Hi All

Ok, after a couple of weeks tinkering with this config I seem to have solved the issue. I would like to do a lot more testing to make sure but so far so good. I created a comp that resets the encoder count of the spindle and the C-axis everytime the machine is set for a new job. the comp is still a bit crude and lacks some sanity checks etc but it seems to be working ok. See attached .comp.

One thing that I cant seem to implement is the use of the pin axis.n.f-errored. according to the man page, this pin should go high when a f-error occurs on that axis. I would like to use that to activate the hydraulic retract function for the x-axis. Linking this in Classicladder to the pin that activates the retract doesn't work for some reason. I have tried "netting" this pin in hal to halui.estop.activate with no result on f-error. I also tried using comparison blocks in classicladder (f-error>f-error-lim) to activate the retract but somehow this doesn't work either. I'm sure I'm missing something small. Any tips welcome

Thanks
