Beware - VR Turning may not play well with old Novaturns

Folks,
For info it appears that the default steps per mm and possibly the spindle encoder settings in VR turning for older novaturns are incorrect.

I have an email in with the sales team to clarify. Will update here when I now more.

Cheers

Fusion 360

Hi Folks, Given how widespread Fusion 360 is becoming in the student / hobby / startup space due to its free licences I thought it'd be good to have some where to chat on here.

Re: G92 threading cycle

Hi Pete, I've been working with the post developed here https://groups.google.com/forum/m/#!msg/nottinghack/UHJuNmfZYOU/O314WNt0AQAJ It's a work in progress. I'll upload a fettled version when I'm happy it's working relatively well. I'm going to optical tachometer the spindle and see if the speeds a...

Re: G92 threading cycle

Hi folks, more threading weirdness. With the DOS control software my novaturn threaded perfectly, in VRTurning it seems to cut the threads compressed in z. I discovered that for my 1999 novaturn the steps per mm were different from the default machine setup in the latest VRTurning so I had to chang...

That clamp/stop on the right looks interesting! Did you machine the yourself? It looks like it's sitting on raised pads, and has tangs to fit the T-slots? What material is it made from?

Has anyone replaced the novamill spindle motor?

Hi all, I've been considering upgrading the spindle motor on my novamill with a more powerful and faster AC one with a VFD, has anyone tried this? What is the power rating for the spindle? Would I trash the bearings running it a 10K RPM? My two reasons are, I'd like the speed for machining with smal...

"Fogbuster" style coolant on a novamill...

Hi folks, Some decent progress has been made on my Novamill upgrades, and I now have coolant. This seems to be having a positive effect on surface finish in free cutting aluminium, and generally how the tools are cutting. Have a look at my YouTube video if you are interested. https://youtu.be/URk_8m...

Re: novamill atc retrofit

Hi folks,
Whilst no where near as elegant as the posts above (that is a work of art!) I have made more progress on my upgrade.

https://youtu.be/7pTLxpIFGF4

I also have a working reverse engineered carousel prototype, and will hopefully be posting videos about that in the near future.

Re: Releasing Tool With No Compressed Air

Hi James, If you are interested in knowing how the power draw-bar works check out my draw-bar upgrade video. You could loosen of the nut at the top of the spring stack and that would release your tool, however beware of loosing the collett balls! If you were really stuck you could replace it with a ...

Novamill automatic indexing 4th axis (3.5 axis) + M62/4

Hi, I am building an arduino 4th axis indexer ( http://www.liming.org/millindex/ ) and am hoping to integrate it with my mill via a pulse from the Aux outputs (Aux 1 M62 on M64 off), is this viable? If not it'll be a manual step in the machining process, and after getting a prototype tool changer wo...

VR milling 2 - z plane arcs

Hi Folks, I'm using fusion 360 for cam which is going pretty well. However some of the linking paths via the denford post use g18/19 plane arcs moves. My novamill doesn't like these, I'm using the official denford post. My mill is rs232 red segment controller and latest VR Milling 2 software. Is it ...

VR milling 2 - continuous tool paths?

Hi folks, I'm now using my novamill more frequently and one of the things that's annoying (from a surface finish perspective) is that the mill doesn't execute consecutive lines of code as a continuous path. The mill stops at the end of each gcode line / move before continuing on to executing the nex...
