General Mach Discussion / Steps (chugging) around radius.
« on: April 28, 2009, 08:51:16 PM »
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.    ???
