Kookaburra: :cheers:

IJ. I wonder if I could buy a length that would fit with no turning, I mean perhaps a length used for the Y axis could be used...hmm I dont have a lathe IJ. fancy some paid work?

Cheers,
Tom

My old school used to have a metal working lathe, I wonder if they will let me borrow it for a donation.

Anyhow, this is going to cost a packet anyway so money is not my concern, postage will have to be paid for most of my stuff from the USA (geckodrives, ballscrews, servos) so whats a few more hundred $$$

Cheers,
Tom

IJ.,

I will miss you. Thank you for sharing, if only for awhile.

Best regards,

All the photos from IJs retrofit can be found here: http://grid.zerofiveone.com/cnc/ij/

I will post up a description of what he did, and how he did it when I have a little more time.

Cheers,

The problem with restoring this thread is that I dont think any backups of the forum db are available. Added to that the forum at the time was enforcing a deny rule on any search engines taking a copy of the site (eg google, archive.com).

The latter has now been resolved, Im not sure about the backups.

Admin, if you need an external site to send a backup of your forumdb I can provide you with 2gb of space, and a 800KB/s uplink so you can send those backups somewhere safe. I think this would give you a 10-20day archive of your forum in case you need to restore that elusive thread

Cheers,
Tom

You know that every post as a icon (upper right, next to the post #) for alerting a bad post, he had the opportunity to press the button and complain if he was being attacked.

[ToMMY2ooo]

Well I think a good idea would be to remove this thread completely, and perhaps start again with a single message containg everything relavent.

For now unban IJ's IP and see what happens, if he doesnt come back or I get the log then thats the end of that and this thread is worthless anyway.

Cheers,
Tom

[cncadmin]

Ian has not emailed me but I have un-banned him the door is open.

3 years on and the machine is still going strong only downtime was from the single phase 240v motor bursting into flames on a semi regular basis....



Since this pic it's grown a VFD and a 3hp 3 phase motor.

It might be an idea to remove this thread Paul..

IJ!!! You are back!

[DennisCNC]

Thats one nice looking mill!!!!
Looks like you are running steppers with encoders, right? Are you using Mach3?

[IJ.]

Sven: LOL yep

Dennis: They're servos and I use DeskCNC.

[Tashammer]

now that is a big'un in the garage. It's lovely and i bet i could play for hours, but what do you make with it IJ?


p.s. funny how Australian sheds and garages are single-skinned and uninsulated - nothing like a wee drop of condensation around the wiring.

it's 7.53 a.m. and damn freezing in Tassy, i'm going back to bed.

Its too bad the majority of this thread was deleted, as it was showed the downside of trying to CNC the Knee, subsequently the quill was made the Z due to the inherent problems of a Z axis knee.

Bon jour young Al i am a newcomer with little or no knowledge and less experience, no workshop and disabled with a work history that has nothing to do with practical things as a result i am sure you understood what you said but i didn't.

Still, i won't let that stop me, hey? :-)

[Al_The_Man]

What I was aluding to was the often failed attempts to make the Knee (Knee Mill) the Z axis instead of the Quill, the quill is the vertical machining mechanism that is normally used to move the tool in the vertical direction, the knee is usually used to just move the table up and down in the vertical direction closer or farther from the quill to accomodate the work piece.
However due to the knee having considerable weight it is much harder to make this a machining axis instead of the quill, when converting to CNC.

I converted the "knee" to motorized, but monoter with a DRO for precise position. The 6" quill is positioned by the program..When I see a need to increase(or decrease ),just program in a pause, usually 60 seconds.It works if I'm alert.

I have saved the 4th axis for a rotary table ( horz.& vert.) with a servo.


Adobe (old as dirt)

[Al_The_Man]

I have an Excello with motorized - counter balanced knee and Z quill.
I just program in a M0 and a message text if it requires a knee change in the prog. Just push start button to continue.
Al.

[IJ.]

Al: Yep sorry about that......

I ended up putting the old x axis powerfeed on the Knee so I don't have to crank it for height changes.

Tas: I make small production runs of parts as a hobby it keeps me off the streets
