I've never needed gauge blocks and they're expensive beasts. Unlikely ever to need them with CNC

Two options:

A) use a separate 5v usb 'charger' (wall wart)

B) my preference - use a 24v to 5v buck converter, e.g. eBay item 221546337415 - there are lots like this with either USB or screw...

Or get a bench grinder and learn to sharpen them yourself ;)

Have a look at this thread which shows how to calculate heat loss and insulation needs. I'd hazard a guess that 150mm of insulation with a vapour barrier and 18mm osb would be dry n toasty with a...

re bolting stuff. Generally bolt dia less 1 to 2 x pitch. So for M8x1mm pitch thread, 6 - 7mm is typical, though for light loads 4 - 5mm might be adequate. A simple rule is to look at the thickness...

Jpg or gif or png all work and display in the web page. Pdf is good for downloadable documents but doesn't display in the page.

Quick tutorial using simple rule of thumb calcs:

V(DC) =1.4 x V(AC) so for 42v DC you need 42/1.4 = 30v AC transformer. Ideally you should add 2v for the drop in the rectifier but 32v transformer...

whats the radius of the slot? or is it a true semicircle so diameter = 22.226mm (spurious level of accuracy aside), or 7/8". Maybe you can find a 7/8" ball nose cutter.

You should only use CY for CNC equipment, especially the connections to moving parts, as the SY isn't flexible enough. Here's the official blurb, taken from http://www.bs6500.co.uk/

yes., assuming BOB xn(GND) and 5v GND are connected (I'd be surprised if they're not)

Your first picture, yes... I'd try that first before making an intermediate driver.. or change the BOB for one with better output drivers...
.
And don't connect motor supply and BOB supply grounds...

I just edited my post having re-read the datasheets. The leadshine 16mA is a max value when using > 5v sources, used to calculate the additional external resistor, its not relevant here. On a true...

Oh dear, you have a lot to learn. Current is like water flowing in a pipe. If the pipe's too small it'll burst (get hot), but it doesn't matter if the pipe's too big. Voltage is like pressure...

No. The screens are connected to the star point at the driver end. The correct way to do this is to separate out the braid and solder onto it some hook up wire (use 7/0.2 or 16/0.2) then fold it back...

the optimum bolt size is the one that gives sufficient thread. generally you need at least 3 threads. so M6 x 1 will just give you 3, M8 x 1.25 will only give 2, so M6 but you'll need more of them to...

Don't... They are crap steppers with 9mH inductance... On 36v they'll perform like treacle. Don't buy any unless they are 3.5mH or lower and even those really need 60v supply on 80v drivers

You would do well to start your own thread, it would get more attention.

But to answer your question, floppy and CD steppers are often odd types, like 5-phase, rather than the standard 2-phase...

Basically a ring of ferrite. You wind a few turns of your cable onto it and it acts as a high frequency choke. For smaller cables you can also use a ferrite bead which you slip over the cable or a...

It's only a low level signal so yes it's overkill, a simple twisted pair would do

I'd be surprised if you got that much a temp difference between screw and bed rail given they're only going to be a couple of 100mm apart or so.I'd turn the screw end down to say 15 or 12mm depending...

Its a problem with IE10 & IE11.

Use Chrome?

or something else...


edit: this looks ok in Chrome

Chargepump enable output is pin1, if you cant get MACH3 outputting a chargepump signal to pin 1 jumper J13 on the board overrides...

A hi-fi/TV repair place wouldn't know where to start. This is a specialist job - you need to know how brushless controllers work to start with. I suspect the manufacturer wouldn't bother fault...

Sorry to have to say this, but your lack of understanding of electronics means you are clutching at straws. Almost certainly one or more of your output MOSFETs is faulty. Simple resistance...

The L7824 is a 24volt voltage regulator. Resistance measurements across it's legs tells you nothing about it's condition.

They're pretty indestructible, having built-in thermal shutdown, output...
