Thank you. I’m actually using 440.19 and SPJS 1.80 and also 1.83 and have had no problems. My problem in the past has been overloading of the buffer with other version of SPJS that have resulted with the machine pausing.
I have not had a problem with CW or CCW circles run in gcode generated by CamBam, either in inches or mm. Here is a dropbox link to a file that I ran in air just a little while ago. Most circles are G2 but some G3 also.
Thanks again.
Rick
