Have you figured out how to get fine tilt angle control?
A good way would probably be a stepper motor driven by an Arduino with stepper shield. But I haven’t been following the full conversation although I am in the process of building a simpler smaller slider using a stepper speed controller.
Hello All,
Yes,
I’m redoing a little tutorial this weekend, with the inclination on demand, fast or soft, with this new tutorial it will be possible to make better captures of the human body or large object.
Small modification on my slider to make the scan completely controllable and fluid at 100% (no tracking loss), I had to switch to a nema17 which makes it more fluid and allows slower or faster control.

Super, can’t wait for the STL files.
I added an external offline controller to my setup.

Printing now,
I changed the mainboard to a " Genmtisu 3018-PROVer" because I wanted a offline controller in addition to GRBL by USB,
I plan to use the laser header to trigger a camera for photogrammetry. So tilt will be perfect.
Thanks

Still a work in progress. I tried to use the original 42SHD0001 stepper for the tilt motor and it does not have enough torque. Once the camera tilts forward, it falls to about 90 degrees down.
The 3d printable spacers for the four M5 bolts were a little short in height. They measured like 4.7mm tall, so the two plates were rubbing the v-slot. Found these M5 spacer, which fit much better;
Choose the M5 x 10mm OD x 5.3mm ID x 5mm length

I mounted Nema 17 (42SHD0001-24B) it works perfectly.
for the connection between the POP support and the Nema 17 I use this
Universal Aluminum Hub 5mm
What do you have set for the Z axis under Max rate and acceleration?
Mine are set to 1000.000 for rate and 100.000 for accel, other then a setting it would have to be this main board I am using Genmitsu 3018-PROVer
My main board is damaged, the Z stepper had two pins at the motor reversed, anyway there is no holding current on Z
amazing! some Nema need to be re-broached correctly but they do not damage the cards! have you adjusted the voltage of the drivers? for my Nema I am at 0.20V per example.
$1=255 for blocking motors (this way they are permanently powered like CNCs)
When I send a G0 Y100 command to my board, it makes a “click” sound but doesn’t move. Any guesses?
Maybe one of my NEMA 17 control wires isn’t connected?
Nevermind. I just restarted CNCjs and it is moving now.

Set up to measure current to the stepper motors by placing an ampmeter in line with one lead to the motor, which is shown as an alternate method of adjusting VREF.
Y which works fine, has .123 amps for holding current and .319 amps when moving. (rated for .400)
Z the problem channel, has some holding current for a short time, then it goes away to 0, when moving it draws 4.0 amps. (rated for.400)
when swapping motors to other channels, the Z motor 42HD0001-24, always draws high current.
And the Z channel always drops the holding current to zero.
I believe the 42HD0001-24 and the Genmitsu PROVer are toast, junk.
When I connected the 42HD000-24 to the Arduino and CNC Shield v3, the fuse blew on the shield. (Before I started measuring current)

Hello,
below the feet of the turntable, there are screws.

How do I attach “bracket_full_nema17” to nema17?
I can’t find the stl file anywhere.
