Nice build and attention to detail
Thanks for posting

Exceptional work - worth waiting for.

Hi Steve,
Mounting the 4th axis on the T slot would provide the biggest swing. I haven't looked too seriously at that yet and will tackle it down the track.

On the X axis I used 20 tooth on the...

Thanks Jack

Steve,
The 4th axis needs to be finished. I have to make a bed for it to be mounted on - not sure if I am going to utilize the T slot in the table or machine something else. It was an...

Hi Aristo,
My main workshop is 4.5m by 8.5m and I have a clean room 6m by 3m as well as a couple of small garden sheds to store inflammable and other materials. All are full so for assembly I use...

Thanks,
I am pleased with the machine and it should serve me well for quite a while.

Hi Steve,
Having retired recently and having more time on my hands I revived this machine build and completed it a couple of weeks ago. I do have a video but it will not upload and my youtube...

Thanks for the spindle details - looks good.

Your build is coming along nicely.
Can you provide details and the supplier of the spindle - 50000rpm interests me.

Hi Bill,
If you had had servos then you would expect better performance. You probably have got the maximim from the steppers but if you want to check out if it is harmonics try fitting dampeners to...

Hi Mike,
Sorry should have said 5mm - they are 1605 ballscrews.
They have almost 2 to 1 ratio pulleys from the motor to the ballscrew. Hopefully you will be able to pick that up in the photos. The...

Hi Bill,
The VFD is mounted on the door on the right hand side. The doors are 4mm checker plate and behind the left hand side door is the computer.
A hole was cut in the door and a folded up galvo...

Hi Mic,
They were 16mm ballscrews out of China.
cheers,
Rod

Sorry on post #3 you said a machine.

You won't get CNC parts in Perth unless you want to pay twice what they are worth. Ebay is your friend and for motors and drivers try Homann Designs or...

If you are looking for a complete machine Tubot is up for sale - slightly larger than A4 cutting envelope and machine and base will fit through standard door.

CNCfun&games,
Good to see this thread active again and look forward to seeing more of your builds.

Build slowed due to doing all the electrics while it was easier to access with the cover off.
First photo shows the VFD, Air Pump and power supplies all rigged up and last photo is the side fitted. ...

I will run a 1.5kw Chinese air cooled spindle. A bit limited by ER11 chuck size but about right size for the cutting envelope of the machine.

Electronics will be gecko 251's, smoothstepper, C10...

With only a little extra effort I can make mine look worse too. :)

The last panel is done and the frame tapped but before it gets fixed it will be easier to do the electrics while there is full access.

Here is the power supplies rigged up and I have terminal...

It was 39 degrees so not comfortable working today and tomorrow will be the same.

Got a bit done on the back of the machine including a couple of fans for air flow around the computer and two...

A fellow in far north Queensland is building a cantilever machine and I am having a bit of fun with him.
By the way I can't see any of your pictures.

Steve,
I use THK or IKO...

I get the rails and ballscrews and make the machine to those sizes. Remember you loose around 200mm travel in the rails on X axis and 150 in the Y axis rails. This is the connections between the...

Thanks Steve,
This is following a build I have done before so it is a tried and tested design that works. The plates are not a necessity but they do add rigiidty and I don't regret adding them....

Been a bit slack although this part of the build is fidly and takes time anyway. Clearing out the camera so a couple of shots to update the thread.

I made a facia for the electrical switches and...

Thanks for your suggestions.

Perth is normally dry but we do get humid weather. It is the extreme of long hot spells followed by a humid change that worried me. I have seen sheets of MDF bow is...

Assuming timber or composite timber material would still be subject to humidity changes what then would make a good stable sandwitch material for a laminated plate?

It all depends where your spindle or router is positioned. As a general rule I allow 30mm between bottom of the collet nut and the spoil board. This asumes the collet nut is below the Z axis backing...

A little more of the base. I have recycled some panels from verge collections so there are joins and there were a few cosmetic scratches but I have managed to avoid the worst.
Top and base is 25mm...

I am the least qualified person to say this but my gut feeling is this is a linear motor. That would explain the on/off state and problem with the SSR and the pulsing air flow.
I may have invented...
