Looks like it's the emmiter half of a pair of sensors so no use without the receiver.

I wouldn't look less than a dual core PC, win7 and less than 2gb ram + 1gb ram graphic card, preferably ATI. 80-100eur here in Spain, second hand. With this you will have 0 problems.


Though It...

Ray i had both running no problem on my last laptop which was a 1.9 celeron and only 1 gb of ram (on Ubuntu 12.04). As with most hi screen rendering apps just make sure you have the best graphics and...

I'm another complete novice, but came across this cnc4free.org homepage through following a link on here somewhere. The guy who's site it is has produced a free e-book downloadable from his site...

Ray,

Suggest you put shielded cable on your steppers other wise your asking for trouble.!!

Agree with Jonathan regards CamBam being good start.

If you remove the handles you'll get far higher acceleration and probably higher speed than with them attached.

Cambam, CamBam CNC Software is good to start with.

Yes but wouldn't be my first choice to fasten box on stepper directly but if your only option then fine. Have you seen these type motor end covers with connections Nema 24 (60mm) stepper motor end...

Yes you read correct but think you must have missed this bit.? . . ."One thing I've done in past is have a small connection box near Stepper so unshielded wires to motor are short, I wrap these with...

Ray I know you have layed it out now but I would move the Bob away from the PSU it's rather close and you want to keep signal wires away from power cables.
Try to run signal wires and power wires...

Personally I'd use some shielded cable and shorten wires on motors and run this back to cabinet.

And here's one I made earlier. . !!!! . . . . Well started it just not finished yet. . Lol 10284

It's never a good idea to cut spare wires off anything, best to terminate them with some heat shrink sleeving if unused.
I'm planning to mount a terminal box to the machine where all the on board...

Ok first you do need all wires DONT CUT ANY. . . . You have 4 pairs not 4 used and 4 spare. If your unsure then post the model numbers or data sheets and I'll tell you the wire colours to join...

With bipolar wiring you still use all the wires, by putting the coils in series or parallel. Parallel is almost invariably the better option, so don't start cutting them off! Consult the diagrams in...

The width depends on what you're doing, but in general 15mm wide is fine. If it's a long belt then increasing to 25mm is a good idea as it will raise the stiffness.

By longer I think you mean the...

what width of belt is best? and is it better to have a longer pulley on either the motor or the screw? or does this not matter?

Definately 5mm

Most people use HTD belts.
Bearingstation are the cheapest place I know of in England, but lately you'd probably get them quicker if you ordered from aliexpress! There's also Belting Online, who...

I have pulleys for 3:1 on my Z-axis as well!

However, this interesting response was a reply when I asked the very same question:...

I'd go 3:1 with small pulley on stepper.

If you want to relieve some stress on the motor then use some form of counter balance, either weights or gas struts.

It all depends what gear ratios you want to achieve. Generally speaking, a direct drive system would use either Oldham Couplings or drive pulleys of the same diameter. For increased torque and slower...

Well really that depends on what your after.? If your wanting higher speeds then larger pulley on driver, this will come at the cost of torque.
If have a fast motor and are wanting slower speeds...

I've still got the 600W DC motor and associated electrics from my Warco WM 16 if you're interested?
