Feature request for A axis output instead of E. I've been working with linuxCNC for 3D printing for the last couple of months. I'm finding it to be quite challenging to utilize any slicing software to output standard machine gcode as interpreted by LinuxCNC. I have to manually edit each program and change the starting code as well as replacing all E values for A. Having the correct code generated automatically would be fantastic. If anybody else out there is using Linux to run their machine maybe you could chime in with other tweaks I've overlooked.
