Yeah i found that out about the lmd18245 chips, i guess i should have looked at them harder. I think i will focus a design on the 7051 chips or go with one of the open source boards. For now i will stay away from a pic driven board. I would like to build a board per axis and then use a pic18f452 to control everything from the com port or usb if i get a chance but thats all later. Maybe next winter. As for now i just want to get some boards done for the new steppers i have. Build my bigger router and go from there. As it is bitterly cold out right now i am more interested in doing indoor electronics type stuff rather then outdoor wood cutting router building type stuff. Thanx. |
