Re: Corrosion and rs232 performance

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 ...

Corrosion and rs232 performance

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...

Fitting a 3d touch probe to a novamill.

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...

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

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.

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.

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.
