Hi Jake,

Another User also discovered that bug but hasn't had time to test our fix. It seems to be triggered by small moves when larger buffering times are specified. Recent test versions have a buffer underflow protection that is designed to reduce feedrate in the unlikely event the buffer becomes critically low. Previous versions allowed the buffer to run empty and starve. This protection needs to be turned off when the buffer is really at the end and it is desired to run empty. A "FlushBuf" command is need to allow KFLOP to do this. We found a special case where the Mach3 Plugin did not do this.

Here is a patched plugin that should fix the hang after a Mach3 "Step". Copy to Mach3 Plugins directory to try.

Please let us know if this solves the problem.
