And I think you'll find a setting in windows somewhere to change the default file format for vcarve.

Have you tried just changing the
file extension to txt from nc? Windows will raise a warning, just ignore it.

I think the reason for shielding stepper wires is to minimise radiated EMY considering they are carrying fast high current pulses. IF the servo includes its driver in the package the signal levels...

Quite a lot to unpack here.

First, with some rewiring everything except the spindle motor should be able to run directly from the mains, without using the step-down transformer.

The spindle...

What grade brass is it? Did you change to new stock recently? Hard brass, cz121, generally machines very well with normal tools but more ductile types can be horrid.

I attach a Sprint manual which may not be for your precise type but they seem fairly generic. For a quick fix, you could either
(a) connect the speed control input on the drive direct to...

Another point about these BoBs (for which documentation is very scarce) is that the logic inputs have an opto isolator with a 1k resistor connected to the +ve supply, the 12V one not 5V, and expect...

Having just installed one of those BoBs to replace the old one on my lathe, I can say with confidence that the 12v and 5v grounds are commoned! Therefore the 0-10v output is not ground isolated. ...

Are you using the original Sprint speed controller? If so do NOT try connecting the BoB 0-10v output to it as the controller is isolated from ground and its 0v floats at something round half mains...

Long a problem with vinyl records. Google for Zerostat guns.

lhttp://www.lathes.co.uk/boxfordmiller/ says that the spindle is Int30.

Not particularly I think. Half-horsepower (375W) dc motor running at spindle speed.

The toothed belts on my Novamill have no signs of wear-induced backlash after 20 odd years. Timing belts are much easier to fit than gears too. But I agree that finer pitch ballscrew and direct...

Do you mean gears? Using ballscrews the last thing you want is backlash in gears. But reduction using toothed belt would be fine. For precision better to use a bit more mechanical reduction than...

Hard to say if it would stall at the lower speed, that's more a function of torque than power. Just change the pulley ratio surely? But you can vary the speed with the VFD of course.

Ideally you...

Great, well done! MOSFETs are nice devices.

Good stuff, glad to help.

Use an old phone charger with USB output, butcher a USB lead to get at the power conductors. Yes you MUST connect the earths. Probe is specced for 5V I think so you should use that.

It is actually a "solid state relay" so may be similar to what you were trying to use anyway.

That's the sort of thing, but you need to know more about the Gecko inputs. Their manual is silent on the input config except to say that they expect to be grounded by a switch which implies there's...

These probes are basically to the original Renishaw design, which in effect have a pair of contacts that are closed before triggered and open when the probe moves the slightest amount. So this is...

No problem, let me know how you get on if you need more help. There is also a CNC Drives forum at http://www.forum.cncdrive.com/ which is very helpful.

I upgraded from an old XP machine with PP to a Dell Win10 machine last year, using UC100s. (One for mill and one for lathe.) Process was painless, I just transferred the xml file that defines the...

Right, I've just tried this. Look at the Feedrate DRO just above the MDI. If M3 has just been started it probably says 5 mm/min. So if you type in Z-5 it crawls along. To be frank I've never not...

I've seen the Taig in action at an exhibition and it looks pretty capable.
