Yes, Mach Arcs inch.  Only other is the ATC, and I believe that is for Auto Tool Changer.  Right?  I have been super busy and have not gotten to the machine.  Tonight I will be trouble shooting.  Thanks, James.

I have not tried any manual moves.  Not sure how.  Until recent my parts have been small.  Larger parts seem to have bigger marks.  CV is on.  Backlash off.  Not sure where to set CV numbers on settings page.  It does seem to go one direction at a time instead of combining X and Y movement together.   My original set up I could draw a square with a diagonal line with a pen and it looked great.  I will have to try it again.    James

General Mach Discussion / Steps (chugging) around radius.

I am wondering if any one can help, or point me to a post that covers my problem.  I am running Mach3, using Vcarve and Aspire.  I am using a solsylva machine with 18 tpi, 200 step motors, hobby cnc pro board. CV is on, backlash is off, and I have tuned my motors the best I can.  I am only able to run at about 30 to 35 ipm.  My problem is that all of my radius' have tool marks on them.  The machine seems to chug or jerk around.  It runs great in a straight line.  My recent, more detailed projects have needed a lot of clean up.  Not what I was looking forward to in a cnc..    Thanks, James.
