Weird thing when I was tuning mine - out off 3 sets 1 would auto tune the other 2 would not. I swapped the drives over on the 2 that would not auto tune and they have worked great ever since -...

Hi Roger
I have 5 others of these motors and drives that work great you're right they do look well made.
It is an AC brushless Servo the model is a SY and the part number is 80SY-M02430-SD20MT -...

Hi Roger
Here's some photos - I'm not sure where to start, I don't want to undo the wrong thing. Any clues?
Thanks

Hi Guys
I purchased a small 750w servo motor and drive from Sale CNC in China about 5 or 6 years ago for a - at that time - future project. That project is about to start so I powered up the motor...

Hi Keetha
I'm about 160kms west of Sydney. The stand is a good size - I made mine about that - just make sure you can get an engine crane under it - I didn't and I had to extend the legs - these...

Hi Mate, I have the similar machine - I got mine from Titan Machinery on the central coast of NSW. You would be surprised how much room you need to leave. It's best to lay out your components and...

Hi Thanks for the nice words, all the parts I have purchased have been done over a long time - 3 or so years, so if you were to do it in one hit you would need a big budget but I have done this by...

Hi Gus
Do you mean performance wise - I have only bench tested it - it pumps oil great and has plenty of pressure - it's quiet and it seams well built. the electronics are neat and tidy and the...

Here is the layout of the control system. All the high voltage (240 volt) wiring has been completed - all single phase.

I've mounted the control enclosure onto 2 50mm x 5 angle iron mounts that have been welded to the machine frame.

So after the coolant is strained and drained it makes it's way down to my filter in the top of the coolant tank. The filter is built on a very sturdy plastic tray in which I drilled a few hundred...

The coolant tray has been attached to the base frame here,

These are the primary strainers to stop most of the bigger chips getting back to the tank. I just started with some standard...

Another of the small jobs done is the mounting of the air regulator/filter/oiler. Not much of a job but they all add up.

Continuing along - I have mounted the Automatic Oiler to the frame and wired it up. It is controlled by a relay in the control cabinet and that has all been tested O.K.

Hi,
Yes I have been working on the mill but only here and there. Since my last update we have moved and I have been super busy with the new house. We have 10 acres and I have been fencing and other...

Thanks Hoss
I could also paint the PLA to provide some coolant protection.
Steve

Hi Hoss
Sorry to go over things you may have said some time ago but I just can't find the info. I am thinking of 3D printing belt covers and other non structual pieces. May I please ask what...

Hi Zach
I have that exact pump - it works great.

Hi Shepdog

Have a look at this build log - it's the one used as inspiration when I did my RF31 - the secret to success with these mills is to use the quill for your Z axis - mine works great.

Thanks everyone - I think I'll get the passive version.

Thanks everyone - I think I'll get the passive version.
Steve

Thanks for the information guys - now I am wondering what is the actual switching mechanism is in the active probes - is it some sort of electronic gizmo or something else?
Thanks
Steve

Hello Guys
Could someone please let me know the difference between the Active and Passive Probes please. I think I understand how the passive ones work with the 3 pins resting on 6 balls (correct me...

Top Covers and the Connector Board from KSI Labs - it powers 2 switches and has Schmidt Triggers to clean up the signals - they make an easy connection to your break out board.

Here is the trip that passes through the gate in the optical sensor and the spring for returning it out.

A couple of inside assembly pictures. You can put this together so it operates from either...

Keeping the coolant out.

Make a few bronze bushes like pictures one and two. I used 1/4 x 3/8 x 1/16 O Rings sandwiched between the bushes to seal the trip rod.
The trip rod is 1/4 stainless...

Step 2

I forgot from step 1 a 3/8 hole drilled to let the switches wire out and the mounting holes.

A quick trip then through the Anodising Tanks. Loctite a piece of 3/8 copper tube where the...

Hello Guys
It's been a while - I've been busy - everyone knows how it gets. I thought I might do a quick job to get me back into this. So here is the start of my Optical Limit Switches. I have used...
