 current versions and beta updated for Mendel catalyst

rep-snapper firmware compatible. i don't have the pin-outs setup yet, so there is configuring to do in the configuration.h file. i will try to do that in the next few weeks
reps-napper is a Godsend. it is fast and has an interface that is easy. Also it has firmware that runs quite good. FYI the limits disable for max is a little buggy. a workaround is to put -1 near the max pin. this overrides the buggy section and just assumes you don't have or use it.

download rep snapper. here
download firmware for 168/328 arduino here  (locally hosted )

REP RAP host latest version(s) has check-sum reporting. use version before march
I will post that version update soon as well, but i think you will be much happier with rep snapper.
