]]>]]>New to 3d Scanning and was going to build the Atlas Scanner as my first. The only question I have is there somewhere listed all the parts needed to build this. I'm kinda working on a shoestring budget and will have to buy the parts a few at a time. I have a 3D printer so printing out the parts is no problem. It's just the hardware that I would need. Any help would be appreciated.
is possible have the connections from laser and switch to Raspberry pio?
thank you

On the A4988 there's 2 wires coming from motor coil A and 2 coming from motor coil B
Now, the motor is labeled Black(A+), Green(A-), Red(B+), Blue(B-) , do those correlate to the "motor coil A" and "motor coil B" ?
Oh, and if so, which is + ? Would those be the + is black and the red, and - is green and blue ? (same as motor)

]]>I printed and assembled the plastic parts, got the circuit board built from the picture, but...
There's 4 wires on the output side of the circuit board, and I'm using a nema17 stepper motor, so there are also a few wires going to the input of the motor. What I don't see is which wire goes from each of the 4 outputs to which wires on the motor
Other than that minor detail, the build went pretty smoothly

]]>1) Photos on the /start.html#assembly are very hard to discern on my laptop (MacBook Pro retina display) as the photos are very hard to figure out when everything is black. May I suggest they are retaken using the plastic that is still covered with the removable paper for much better contrast? Note clearly at the top of each page that the paper should be removed prior to assembly.
2) Page 1 - #4 - this is where you tell us to use the longer ribbon cable, not at step 29 on page 2!
3) Page 1 - #6 - typo - change "and then connect FC to FB using 3 of the M4 screws" to "and then connect FC to FB using 4 of the M4 screws"
4) Page 1 - exchange the order of 8 & 9
5) Page 1 - (new #9) - typo - change "and sit the Raspberry Pi onto the three screws followed by" with "and sit the Raspberry Pi onto the 4 screws followed by"
6) The diagram on page 4 should show the FT and any other F(x) parts that are not listed there. I had to go to this forum to find the FT which wasted my time.
(I'm sure there are others, but I have to run...)
Setting the turntable up correctly is not simple!
I would suggest that the center holes (for motor shaft) for the discs be a closer tolerance (they can always be enlarged if needed) to get the preset closer, then a countersunk hole in the underside of the turntable to guide the center of the shaft and help ensure alignment.
I would also suggest using the extra round disc (same diameter as FO, but not printed) instead of the printed plastic with the countersunk holes - and longer flat bottom machine screws. One needs to be able to slide the plastic discs around slightly to get the turntable true, and with the countersunk holes and printed disc that combination tends to force it to a setting - which on my unit is not centered.
A great kit none the less, just the instructions and the turntable need a bit of attention to make assembly easier. At my shop I will be making a truing jig for the turntable with a rod the same diameter as the motor shaft and using a drill press to hold it upside down align it that way then bond the plastic discs with methelyne chloride (plastic cement) so it can never shift again!
