I have seached YouTube and Google but cant seem to find a video on how a milling machine (or even a Lathe) is made.

Anyone have any links please

Fished control unit wiring

All i need to do is tidy up the external cables etc

Wohoo, just finished the wiring and done a quick test, it works

Nope Y

I have the supplied Warco power feed on the X axis

Its done via the PWM

As this is my second stepper power feed, i know what i am doing

this is the wiring

The push switches on the frequency generator board were removed and wires soldered to the points shown.
A double pole double throw switch with centre off was used to control the direction and on/off. Shown top right.
A relay was necessary because to start the motor the switch wires are opened not closed as expected.

Got the belt this morning and its the correct size this time, YAY

Crap phone photo. They are nice

I have raised mine for the same reason, stout wooden blocks under neath raises it about 5"

It was the 8Nm one

Have not seen the done to many Warco milling machines and have wanted to do this for a while. After I decided to replace the Nema 23 on the Z axis with a Nema 34 stepper motor I then had a spare Nema 23 and Controller for the Y axis project.

So, you need a Name 23 Stepper Motor, I am using the 3Nm one and the controller bought from Stepperonline --HERE--

I already have a power supply, 48v so going to use that. You will also need a PWM like this --HERE--, a change over relay, a double pole double throw on/off/on switch to control forward and reverse of the motor, a on/off power switch, a LED light (Optional) and some sort of limit switch.

I decided to go with 1 to 1 ratio pulleys and belt which I bought from CNC4U. So everything would fit I bought the 10mm pulleys.

Here is where I am up to today, I am awaiting the PWM and a replacement belt and the one I got was too short (Schoolboy error)

Well I have now fitted the Nema 34, much better, no stalling

I think you have explained it thanks.

I will report back once i have the new motor

I will also create a new thread re the Y axisvand i dont think i have seen someone do this on this sizevand type of mill.

Yet again cheers guys

So, did some more testing and it still stalls, not as much but have decided to buy a Nema 34

With one of these - https://www.ebay.co.uk/itm/325143354034

Ok been doing some checks on my current setup.

The stalling happens when you first turn the motor on. The RPM is 253.

I can adust the Microsteps. Its currently set at 20/4000 steps/rev. If i change it to 25/5000 steps/rev it turns at 203 RPM and does not stall.

To be honest when i installed the stepper i did not fully understand what i was doing so guesed :0

So i am no wondering f i do need to upgrade to a Nema 34? Which will be quite expensive as not only will i need the stepper motor, a driver and a new power suppply (mine is only 6a and the Nema needs min 6a)

if anyone is interested i will start a new thread re Power Feed for Y axis on a Warco WM18

The problem with stepper motors is, as the speed rises the torgue reduces. So you buy a 3Nm one but as i gets the revs up, say 1000rpm, the torque is now only 0.5Nm
