Re: Small metal Lathes / IE 350 to 50W machines
If this is a typical size job then IMO and if you have room you would be better off with something bigger than a C3. Just looked on Arc Euro and it only weighs 40 kg.
The job is within its size... -

Re: Small metal Lathes / IE 350 to 50W machines
One thing worth mentioning about the indexable tooling is not to get one of those sets with lots of different tools for a seemingly good price. Apparently they'll be poor quality, so you're much...

Hi dudz
Just had a quick look @ that and you appear to get a 3 Jaw Chuck as standard, for turning(not milling) square stock you will require the optional extra of the 80mm 4 Jaw Chuck which should... -

Re: Anyone got some 2.5D G-code please ?
Think Art is included as part of trial , it allows bit more control over how it iterprets z-depth, its also twice the price to register.

Re: Proximity Sensors / Mach3 not showing
assuming 1.2v forward voltage on the opto means that the existing series resistor is (5 - 1.2)/.007 =542, so probably 560R. the suggested series resistors of 1,5k for 12v and 3k for 24v give...

Re: Proximity Sensors / Mach3 not showing
Resistor overheating isn't the limiting factor. With 200 ohms you'd have 5/200=25mA. The parallel port can (apparently) only source/sink about 14mA, hence to avoid damaging the port if connecting...

It doesn't say in the listing (Edit: Just spotted the datasheet in the eBay listing, which does say open-collector), but the inductive sensors are probably an open collector output, in which case you...

Just use one normal dial indicator. If you mount it on an arm, which can just be a bent piece of steel bar, you can take measurements at 4 points (i.e. 12:00, 3:00, 6:00 and 9:00 on the clock) and...

Re: 1605 ballnuts
I'd say they would be the same and conform to a standard on the mounting holes, would like to think the same for the rest of the nut dimensions but can only guess at a yes.
