Hi Barry, I would suspect the chips are fine, but i would be concerned about the small traces that are pretty toasty as circled below. if there arent that many that are bad, you might be able to just run solder over the trace to make a track, or jump a little wire from point to point. Cant say for ...

Hi All. I've recently lost Rs232 comms with my novamill first with one of my workshop laptops then both. I've fitted a spare card and am up and working again. If I clean and resolder the highlighted corrosion is it likely to help resolve the issues? Otherwise the board looks fine. 20190923_131528_re...

Hi Dan, Just tried to post some old files and I'm getting this error Have raised an issue in the git, hopefully you can help as my code-fu is very poor!! Many thanks Barry M Error: Failed to evaluate post configuration. Code page changed to '1252 (ANSI - Latin I)' Start time: Wednesday, June 26, 201...

Thanks for sharing Dan, I'll be using it fairly soon, I recently lost my hacked post during a Fusion 360 update so hopefully you've got something a little more robust than mine was. Threading caused me the most headaches! Many Thanks Barry M I have a fusion 360 custom post processor that I have been...

Hi Jeff, Hopefully you're still on the forum... would it be possible to get a copy of your Post? I had one working but lost it during a fusion 360 update. I really don't want to have to start from scratch again as I had lots of fun getting threading working properly. Any help would be much appreciat...

Hi folks, I'm looking at getting a 3d touch probe for my Novamill. It's the type that goes open circuit when the probe tip contacts the work piece in any of the 3 axes. Does the novamill support this? I assume i would connect it to an aux input? I have an original rs232 control box. If so what gcode...

Happy New year all!

Hi Folks, Thought this might be of interest... updates on my DIY toolchange carousel. Its a working prototype but will need machining from metal to make it stiff enough to be reliable.

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.

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. The Denford milling posts can be downloaded by searching for denford here:- https://cam.autodesk.com/hsmposts Unfortunately...

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...

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...

It's aluminium...

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? Cheers Jon Hi Jon, it's a practice piece for the mounting plate (which is square) for my 4th axis I use it as a s...

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...

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...

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.

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

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 ...
