Hello Hood, Erik here.
I managed to get a continuous path (circular & straight) by turning on the "laser" mode, but when it is not in "laser" mode the path reverts to a stop/start with each line of code. Also it seems to have "stuttering" in the Z axis movements and still has a noticeable series of marks in the machined material at every new line of code and a noticeable hesitation at the line where the X/Y motion meets a Z axis movement. Even though the X/Y motion appears and sounds to be continuous the machine still leaves a noticeable mark in the material (Z axis or vertical) that appears to be coincident with the progression of code line to line. Most of the code (85%) is made up of an XYZ command in each line. Do you think this is motor tuning (accel/deccel) or could it be a backlash compensation issue? I tried various feed speeds, but the frequency of the surface inconsistencies remained the same, so I don't think it is mechanical harmonic vibration. I set the look ahead to 500 lines and it did help some. Should not CV mode work even when not set to "laser"? Thanks for your help.
Erik
PS: the the angular stop in CV mode is set to 90 Deg.
