At the risk of seeming a pit picky can I point out that Drag Engraving Cutters are a different thing to Drag Knives, one is not directional and is used for engraving hard surfaces, the other is...

Find left edge, zero DRO, find right edge, set DRO to half the displayed value, zero is now centre line of part.
Repeat for front & back.
It's so quick and easy I don't see why automation is...

Looks like with the right version of FlashAir you can, but it's not an intended or supported function :D

If the parts are made as rigid as they should be the weight will be centred even if the vertical plate carrying it is not.

This is probably shutting the stable door......... but, only bugger about with one thing at a time.
I know it's a temptation to change multiple settings on multiple axes in hardware and software at...

I apologise for assuming the worst, PM me an address that's likely to receive the package and I will re-send, I cannot re-send to a returned address as it could be dodgy RM staff that send back...

Really good locks have rollers in bushes in the bolt to slow down saw and grinder attacks, but very light pressure with a slitting disc will still get through them, it just takes longer than with a...

If you need a placeholder page for your website use your business card, under no circumstances use anything that says "Under Construction" or has a "Men at Work" road sign graphic, that stuff stopped...

I Thread Mill down to M3, some things I make require a full thread right down to a shoulder, this has internal and external full threads to shoulders.

For a Z axis it's more about holding force over speed. The shallower pitch will almost certainly deliver as much Z speed as you need whilst requiring less holding torque.

9.81 Newtons equates to 1Kg Force,

This forum is where people come to have searches done for them ;-)

If it's a serial port on the PC it will have visible pins (male), parallel ports on the PC have holes (female) ;-)

The difference between 1-"whipping in ballscrews" and 2-"Rotational mass is that

1. "Whipping" is when the length allows sag and rotation then "Whips it around" like a skipping rope resulting in...

There is some very simple maths you can apply to sense check the cutting data you have quoted.

42mm/sec = 2520mm/minute
Your cutter has one flute and rotates at 15000rpm,
Divide mm/minute by...

I've made you a 4.2mm drill guide with 9.47mm OD to a shoulder in Hardened Silver Steel.
As it isn't a delicate part it is hardened and not tempered so it will definitely last you your job.
...

Let me have dimensions if you want a drill guide.
I'm afraid there is no room here for mission creep, I have a full order book and assumed you'd have dimensions ready for your request and that I'd...

You could use a ramped profile with very shallow DOC to mark the slot to around 2mm depth prior to cutting it, a bit like using a marking knife in conventional woodwork to prevent torn surface edges...

Don't forget DPC and adequate insulation under the concrete, I wish my workshop floor had insulation under the concrete, it wasn't even though of 40 years ago :-(

Nothing else in the bag, lots of other stuff in the drawer next to it though ;-)

So we're comparing Shonky with Very Shonky and saying that merely Shonky is therefore worth buying for thousands and then repairing to correct basic engineering shortcomings, which the contraptor (I...

That's a shame, I have the big Evolution cutoff saw and I use it for all sorts of things, it did sterling service cutting a load of old thick wall galvanised imperial scaffold poles into manageable...

John,
I have an early pic of the "proof of concept" I knocked up with what I had lying around,

I've subsequently re-worked the spacer support with alternate bearings to reinstate the...

Nylon can absorb up to 20% of it's weight in water and can need 1 to 4 hours at 80C to dry a full reel to the core, PLA at 80C for 1 to 4 hours will yield a nice bit of modern art but no useful...

You can get belts with various reinforcements, fabric, more exotic fibres and steel wires which will all perform differently with changes in temperature and tension.
