HI
I want electric. circuit for cnc 3 axis.please.be cause I want to do it myself.not buy
thanks

here is a link to a schematic for one axis unipolar driver:

There are lots of others out there with various levels of complexity.

thankyou very much

What type of machine are you building? Or are you adding CNC to an existing machine? :wave: I would like to ask what part of Iraq you live?

HI
I live in ERBIL. I wante to built smoll cnc for wax granding
thankyou

I see one schematic in this thread posted by someone named Steve. Questions I have about the circuit in the file named FX60KDGF6B7SXUN.pdf are:

What step sequence does that logic produce?
What is the maximum step frequency that driver can run at?
What are PL(1-5) ?

Thanks for the info.

That is what I am doing. But I would not recommend my circuit for others to use. There are better components available to use today than what I am using. If you could say what motors you would like to drive maybe I, or someone else could be more helpful in showing you where to get a schematic.

Anyhow I am all with you on building your own.

Paul,

That circuit is just a fairly simple driver I found for someone really wanting to build from scratch. The PL(1-5) are most likely "plug" numbers for connection off board to the motor. One part I found interesting in this circuit is the "Incadecent current limiter" Light bulb. The cold filiment of the light bulb offers low resistance, but as it lights up and gets hot, the resistance increases limiting the current. Believe it or not... the original Bose 901 speakers had a light bulb wired in series with the voice coils. That made it impossible to blow the speaker voice coils. I saw a demo once in Germany where a 901 was plugged into a 220 V outlet.... very loud hum, but not blown.

Yes I guess it wouldn't be a bad place to start. Not sure if there is enough information there though. Certainly wouldn't be the highest performing driver on the block I'd think. I like building my own motor drivers. I've done a couple different ones now, planning on checking out some more.
