555 step-direction generator for CNC

[student1616]

hello all,
iam working on a homemade CNC engraving machine.i already finished one phase of it.but before connecting it to computer i want to check it using 555 timer.
my friend said step and direction for CNC can be generated using 555.i want square pulse generator.

*i am building CNC based on Linistepper plan.so in their site(piclist.com) i found below 555 circuit.so can i use it.if yes which is the step and which is direction.

Google '555 astable', this will tell you all you need to know about the stepping.
As for direction, that's just setting the direction pin high or low, it could be done with a 555 but it's a bit 'overkill' just for testing purposes.
From what I have seen of the Linnistepper 555 Timer Kit, it looks like it is just a 555 astable with adjustable frequency and mark space ratio. Hence the two variable resistors.

Ask the question on CNCZONE. The people there build CNC's. Should be able to help with other questions also.
