Hi I have problems cutting large arcs ( 1 metre +) and hope some one can help me . My problem is when I cut large arcs the arc surface has slight wavy edges on the arc circumference, this presents a problem as I am trying to mate several pieces of wood together.
I built my own CNC which is very ridged and is driven by large steppers and run via CNCplayer software (real time DOS so no windows lag) I also designed and made the 8 amps stepper drivers. I draw the patterns on Auto Cad which is then converted to cnc player.
The drawn arc on the screen is perfect and is made up of many nodes. When running the CNC the steppers execute the node then stop this happens on every node. So the x and y axis is stopping and starting many times which I assume may be the problem.
I have tried for hours to resolve but with no luck , can some one suggest what I am doing wrong . I cant work out if it is the soft ware , my amps or the drawing from Auto cad.
Regards Peter
