Rotary4DavidSLS (R4D) XP and Windows7 (8?)
– Auto Scan – AddToList –Alignment – Rotate object and scan again
(for better success with autoAlignment do>= 8 scans )
COMIf Green – COM port is open. With this COM2 is auto selected.
If Red – Connection failed – Then select COMX and use button_O (openPort) –((But_C (closePort)))
Then Write new port Ex: COM3 and Check Auto. Close and Restart
COMMANDS to/from David
-I could not get a letter from Reading theCOM so a get number when david send it – Checked only for
finding the number ( I think the number 50 is the sent “letter 2” ) some binary to letter something :-)
Tx send the written command – Rx receive command and displays it
ROTARY Table Setting
With Direct on Steppermotor 200steps = 360degree -1.8degree/steps-
With Gear – 5:1 – small gear/motor rotate 5 times to turn big gear/table 1 turn (360degree)
so 200*5 = 1000steps =360degree
The-Speed Rotary is actual Step’s Intervall – Time between steps. so this is upside down (-;
High number – Slow speed
Low number –High speed.
( “Checked when Start”-feedback- prevent command from david- and “ MotorActive” is just for
feedback and programming.)

Had to add a gear 1:4 and I use a 12V only 250mA power to this –(( batterypack with the kit-))
or

This should drive a table direct – But you probably need a bigger power and so on .
http://www.pc-control.co.uk/stepperbee_info.htm
Step motor – BLACK AND WHITE to +12V ( MINUSfromPower(GND) to PIN1
---Yellow PIN6---Red PIN7---Orange PIN8---Braun PIN9---
Powersupply 12v 250mA – NOT in the Kit – comes with battery-case:
(battery drain when not moving, stepper’s are always on full power.moves by switching coils in
motor that’s why there are 4wire – the 2 other are connected in the middle of the 2 coils)
stp.dll – COPY to C:/WINDOWS/System32/ (there is two stp.dll – I found a new’er ) that’s for XP
Windows 7 – I have copied stp.dll into C:/WINDOWS/System32/ ---BUT
Also in the same folder as R4D seams to do the trick. (I have both R4D and stp.dll on desktop)
R4D is compiled with option x86 – to work with W7 x64bit –
-has something to do with stp.dll is for 86/32bit system- and WOW64 ....
The Step Motor with this kit is NOT strong and you will need a gear 1:4 .
I made a disk of Acrylic DIA170mm 8mm_thick direct on motor– had to make gear....weird,,
Maybe good to make a belt drive – less vibration – easy to make.
small lightweight model’s vibrate off the table with my gear,,,.......
Wondering about the StepperBee+ -no gear good but probably more vibration- biggerpowersupply more expencive –
Or with a big motor up to 7A –and gears- it may turn around my officechair ;-) well, it makes me wonder.....
There is one more possibility and that’s is one more linear axis that can move the Camera/Projector-Rig to scan a high object...
-maybe very soon – with a big diameter model – more scans on rotary maybe 20 – then rig down 10cm and another round with 20scans-hmmm : auto-alignment –must scan a few one when the CP-RIG move down – since auto align is to previous scan...
