biesse rover 316 retrofit

I believe that there are still bugs in the "new" trajectory planner of Linuxcnc (well it's not really all that new anymore it's 8 years old) that can occasionally cause inexplicable halts and slowdowns. Small tweaks to the g-code can often get rid of the pause, and the same g-code run using a different machine config or PC may give different results. If you can set up your CAM program to generate g-code without any arcs (arcs approximated using tiny line segments) you "shouldn't" see the bug induced pauses, but you will end up with huge ugly g-code files. Another option, if your g-code won't be too speed limited by single line look-a-head, is to set Linuxcnc to use the old tool planner. To change to the old planner add (or change to zero) this line in the [TRAJ] section of your ini file "ARC_BLEND_ENABLE = 0". Set that = 1 to enable the "new" planner. The old planner will limit the machine's speed to the max that the machine config's settings will allow a controlled stop within the distance of the end of the next g-code line segment. (The old system can be hugely limiting for CAM generated small segment contouring g-code, or not limiting at all for simple line and arc boxes where the code segments are relatively long.)
