Grecode

With switchable kinematics the gcode is not changed at all. In your case its just the direction of the x axis that is (mathematically) flipped. It's the most trivial change between two kinematic models since it just inserts a minus into an equation.
Your regular default kinematic that you use now is a righthanded cartesian system for the flipped second kinematic it's changed into a lefthanded cartesian system (ie x axis inverted in your case).

So I don't think you should run into problems using any gcode that runs on your regular setup. In fact I would be more skeptical using an external application like grecode that changes the actual gcode back and forth a number of times.

Note that switching kinematics _will_ change a righthanded helical tool plunge into a lefthanded one. Thus it will change a conventional circle milling operation into a climbing milling operation.

If you're uncertain as to what could happen to particular GCODEs I would encourage you to install the switch kins branch from above and copy my sim folder into the /configs/sim/axis/vismach folder. The simulation can then be chosen from the startup window of linux cnc and you can then load any GCODE you like.

[edit]
Unfortunately the scratch links on the buildbot page do expire after a certain time.

Have you seen the docs on automatic input filters? That might be a solution

linuxcnc.org/docs/2.8/html/config/ini-co...html#_filter_section

switchable kinematics has now been incorporated into master. So maybe you can try the buildbot deb link again?
