Re: Denstep Novaturn not communicating

Hi Peter, for me it was a combination of things, I ended up buying better quality cables and running the cable directly to the card from the laptop rather than using the box wiring loom. I also re-soldered the rs232 socket on the board and cleaned the white corrosion from around the connector. I wou...

Novamill Sprint spindle drive 12v+ source

Hi All, I'm looking to convert my Novamill and have a pwm to 0-10v conversion module to drive the speed demand input. This module requires a 12v+ power supply. Given the floating nature of the 0-10v input is there anywhere on the board I can get an aligned 12v source? Any thoughts would be great. Al...

Denstep Novaturn not communicating

Hi All, My Novaturn has been brilliant for many years but unfortunately today it's not communicating. 7 segment display cycles 0 then L with a flashing dot. The varta 24v surface mount battery has spilled it's guts and left corrosion all over the board and around the rs232 connection. I've removed t...

Re: Novamill Column Raising Block

Hi All, Been a long time. Has anyone considered casting a spacer in polymer granite and then lightly skimming it with a large diameter fly cutter? My other thought was to get some ground steel plate water jet cut to profile then stack them to height. Any constructive thoughts would be much appreciat...

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

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.
