|Thread: WM18 - Z Axis power feed|
Cheers, the smaller motor still lives so may be put to use for something or you can buy it

Progress report. Yeh it a slow progress due let downs by ebay suppliers
I ordered the replacement 3Nm motor which arrives within 2 days, well done EU Stepperonline
Control box is built, wiring done.
I have one question re limit switches. I have one at the top but unsure where or even if, the lower should go. My thinking is depending what I am doing the lower stop will never be in the right place?
|Thread: What hand protection do you use?|
|Thread: Finished my beam engine.|
That looks fab
|Thread: Any ideas please as to waht themay be ?|
Looks a bit like an expresso maker
|Thread: Is your spindle bore large enough?|
I would agree, I have 38mm and sometimes wish it was bigger, in fact I just wish I had a bigger lathe
Just looking at your photo made me realise I have never used the steady

My WM18 has the gas strut, had to reinstall it when I assembled the machine in the hut.
It was SillyOldDuffer's machine that needed 6.6kg as his does not have the gas strut
You will have to try harder than that

I have the Warco one, however the motor has now stopped working, so in the bin it goes
Thanks for that. Does your WM18 have the gas strut
My WM18 has the gas strut and was std
You are in the dog house!
I cant send the motor back becuase I shortened the wires
Top end of the column :0
Is this any help: Frequency: High: 5.8KHZ-127KHZ, Mid: 590HZ-15.8KHZ, Low: 82HZ-2.3KHZ
At either 2.8a, 3.1 or 3.7 its truggles at the top end with the jibs loosened off.
So I am going to see if they will swap the motor for me.
I'll send you the bill Chris
That was the YouTube vid I followed, however he is used the 3nm motor.
I also wonder, the X axis is a lot easier to feed that the Z, concidering the weight of the head.
Just a thought Chris

I am starting to feel the 3nm motor may have been better Link
Before fitting I bench tested the motor and it was turning fine.
When I first fitted it the dip switches were set to 1 amp, when I set it to the required amperage, 2.8, it stated working on the mill.
I don't have an occiliscpoe
The stepper motor ChrisB linked to does not seem powerfull enough and cant turn the lead screw
Edit: The current switches were set to the lowest current. However as the head raises it get a little tighter and the motor then struggles, currently looking into why it gets tighter

Currently my thought are just to raise lower the head however once done it may well be good enough to feed while cutting.
re your second statement, will, yes i could just do that. Bit Heath Robinson but each to their own.
for me its also the enjoyment of the project
Work has started, got the mount, connection and motor installed
Just waiting for delivery of the PWM and project boxes then I can start the wiring.
Next task while waiting id to fit the limit switched.
Re the wiring would it be worth covering the wire metal conduit What size and where from? Or I could use this stuff Link
The motor only put a small amount of resistance on the handle so happy
