Mine wants sgcore.dll too.

The usual simple solution is the parallel port address, which is unlikely to be the same on your new PC's. Catches me every time.

Jimbo,
my Turbocad is a bit old now, V9 I think . It's certainly exciting to have some attention given to the lathe at last.

Jimbo,
unfortunately I now can't open the dxf in turbocad. Amazing how nonexchangeable this format is. Strangely enough, I use the format quite a bit for exchanging circuit diagrams with one of my clients. He generates his in Autocad & I generate mine with Seetrax Ranger ( A PCB cad package ) & we have no problems. I can view either of them on Turbocad, but I've found very few of the dxf's on this topic will display.
I can view your dxf now in Lturn ( It still says it isn't the correct format) but after moving  the axes to x0 z0 at the rhs I still can't get it to take my dxf at all.
This is just a test piece so it's not worth a lot of effort. It's just an example of a real job that I may want to do on the lathe.
Lazycam seems to handle it reasonably well - I'm not really clear why there is such a difference in the input file acceptance. Presumably Art is using a completely different decode/ display method. I do like the new style though.

Jimbo,
thanks for that, I wasn't aware the lights did anything when in 2d. It doesn't get me very much further in the load though.
Interestingly this profile loads & produces code without any problems in Lcam.

Great to see some movement in the turning department. I use Turbocad & am finding problems loading some of the dxfs posted here. The pulley & the column for instance give a 'Viewport entity with no extended data ' error. Conversely I can't load some of my dxfs into Lazyturn. Here's one.

Russ,
check your pulley settings. Assuming you have pulley 1 set, set the max speed as 24000 or a bit higher, ratio 1. That will probably get you into the right sort of area.

Chris,
you didn't say whether you'd tried changing the active hi/lo. My test shows that it does matter, and can give the effect that you're seeing. The diagnostics still show the signal changing, but the tacho does not work or gives strange readings.
I'm using a bob with opto isolation.

Tony

Yup, that's it. If I set active lo (green tick in the box) on my index/timing input, I get no tacho.

Chris,
I assume that you're using the index input as opposed to the timing input. I say this because I didn't realise for some time that there were two different inputs. With one slot use index, with two or more use timing. With more than one you need one slot 50% wider than the others. I would have thought your slot width would have worked ok, certainly at low speeds. It's only when you get fairly fast that the slot size gets critical. There is information on working it out in the Mach manual.
Have you payed with the active Hi/lo setting? I seem to remember it having an effect on my setup. I'll try & run the lathe up & try it.

Tony
