Hi,
new member about to build cnc plasma cutter 2500mm x 1250mm using mach4, smothstepper, mb3 bob, rack and pinion X and Y axis ballscrew Z axis using 4Nm steppers (twin on X axis).
Previous cnc experience - built cnc router in early 90's using SMCU+ software from North East Electronics with 1/2 step drivers (micro stepping was a very expensive new technology). Software ran on dos and came on 4 no. five and a quarter inch floppy disks, all g code had to be computed manually and entered line by line on the keyboard.
Machine still in use today although now on 4th router head and computer upgraded from old 286 to 486 running windows 95.
Obviously got to learn new control software so any hints and tips would be a great help.
Thanks.
Ken.
