I think you're talking about running 5 steppers in total? One on the X, two on the Y , one on the Z and one on A (a rotary)?
I've seen a rule of thumb of 2/3 the rated stepper motor current for...

Hello all,

I've converted a G0704 to CNC. I used Stepperonline closed-loop steppers with CL57Y (X&Y) and CL86Y (Z) drivers.
The mill is up and running and now I'm just fine tuning.

I've...

Thanks for all the replies. I'm getting a pretty good idea how to go about getting the metal I'll need. My mill is supposed to arrive today; looking forward to making first chips soon.

Thanks for the link Hoss. There are certainly some bits there that I could use. I also called the local metal place today to see about picking up some cheap drops... They wouldn't even talk to me...

Off topic but thought I'd post this anyway.
I've been reading about milling machines, tooling, cutters, rotary tables, etc. for 12-14 hours per day for several days now. Trying to educate myself...

I too bought a 4" vice, so it makes sense to get some 4" I suppose. Starting to think that some 4" from the local supplier and shorter chunks of bigger stuff from eBay would be a good choice.

Yet another newbie,
I just ordered a G0704 to make some parts for a project I'm working on and ideas I've had kicking around in my head for years. I've never used a milling machine before, but 100...

Just an update...
I bought a PLC from Velocio; an ACE11. I also bought a 3-axis stepper kit off eBay and the plc controls them well enough. I also bought some linear rails, timing belt and pulleys....

A bit of both actually. I'm looking to have two axes move a part in space and bring it to a two axes CNC router (spiral saw). The spiral saw will cut a circular hole. The part will rotate to another...

I was looking to Mach3 because I was thinking of using the same hardware (steppers, drivers, PS, etc) to run on a few different machines to perform different tasks. Move the hardware to a new chassis...

How would the PLCs interface with Mach3 for timing? I know what they are but haven't worked with them.

Hi,
I'm so new to CNC that I don't even know what question to ask... I've been reading for a few days but haven't been able to find what I'm looking for.
I'm a hobby level guy looking to build a...

Hello,
I'm a hobby level guy that's new to CNC. I'm interested in building a robotic machine to automate a process. I have a long history in electronics but almost none in programming.
