Hi,

Great idea!!! Looking forward 😉
Any ETA?

Hello?
Raspberry pie 4 can also be use

How smooth has the motion been compared to the round rod original? On my original I have yet to achieve a video result that didn’t have noticeable jiggling.
I even removed the top rotating plate and put a camera screw directly up through the travelling base plate into the base of the camera, no base plate, no ball joint, and it still shows irregular waviness.
This is with a Vixia camcorder HR F50 that weighs only 285 grams.

I think I need to convert my slider to this X extrusion version 2. My guess is the round rods allow the whole thing to twist and it develops oscillations as the slider moves along. Like a rope foot bridge across a canyon.

The new camera slider is way smoother than the old one. Mainly because the lateral force applied during the PAN movement has been drastically reduced using a thin profile.
Additionally, the TMC2208 stepper motor drivers works way better (and are quieter, almost silent) than the regular A4988. The TMC “creates” virtual steps (up to 256 instead of 16), making the movement constant not subject to small steps.

I did install the TMC2208 drivers earlier this year and that is like night and day. So inexpensive and easy to do as well. The odd thing is the little heat sinks mine came with are a wee bit higher so the enclosure lid does not close. Not a problem – I want to design a roomier enclosure anyway.

To clarify your comment “reduced using a thin profile” – by profile do you mean the v-slot extrusion instead of rods, or some other component/design change?

Thank you.

I meant the aluminium profile, the V-wheel bearing work better with the aluminium rail than the rods (and it is lighter)

I ordered spare steppers and received the new TMC2208 drivers also. The specs look better on them with the new finer precision stepping action. I also received the tiniest micro-aluminum heatsinks with them; if the new drivers generate less heat, they might work OK. For me, I’m going to use the much-larger blue aluminum heatsinks that I already know work fine with the older drivers. They are readily available on both Amazon and eBay; I paid $7.45US for 10; cheaper if you order from China and are willing to wait longer.


You can check the BOM here

Note: this new BOM shows the new stepper drivers, but with the old blue aluminum heatsinks, not those much smaller ones you are actually shipping that I just received. Which ones are you going to standardize going forward on for the newer better stepper drivers? Thanks for clarifying.

The camera slider “needs” smooth motor drivers so we opted for the TMC2208. They are as accurate as the regular A4988 but they are silent and more smooth. Did you order the A4988? They will work but please notice this: the motors will spin in the opposite direction. We are just including the TMC2208 with the CAMERA SLIDER KIT

Update: The new TMC2208 steppers work great. I used the large blue heatsinks I ordered rather than the smaller bare-aluminum ones. Yes, I had to pull the stepper cables off the Devia 4-pin headers carefully and reseat them to get the motors to spin the desired directions. All is good.

Of course it can.
We recommend you a 12V or 9V battery holder with the regular 5.5mm connector, like this one:
https://www.amazon.com/5-5×2-1mm-Connector-8×1-5V-Battery-Holder/dp/B01GEBW7Q8/ref=sr_1_6?keywords=battery+holder+12v&qid=1582536742&sr=8-6

Or if you are planning to connect it to your car battery, use this one: https://www.amazon.com/12V-24V-Charger-Power-Supply-Cable/dp/B07DKXWRVD/ref=sr_1_1?crid=ZZGLLIUCP0FU&keywords=12v+dc+5.5mm+x+2.1mm+car+cigarette+lighter+power+supply+adapter+cable&qid=1582536831&sprefix=car+12v+5.5%2Caps%2C252&sr=8-1

We will add a battery holder to the KIT asap. Would you like to get one from us (a 9V, 6xAA batteries)?

I am using this battery pack. : https://nl.aliexpress.com/item/32988790342.html?spm=a2g0o.productlist.0.0.30b156735BYITG&algo_pvid=4b4b8d23-62f9-4183-834e-dbe343c99af8&algo_expid=4b4b8d23-62f9-4183-834e-dbe343c99af8-6&btsid=0ab50f4415906604166585384e38d4&ws_ab_test=searchweb0_0,searchweb201602_,searchweb201603_
Been testing yesterday and got around 1 hour of footage, without draining the battery pack. But you can get a 20000mah for 23 euro so that is pretty nice.

Thanks for the link. We just got one! 🙂

How can Devia work away from home? I only see AC option. I think I remembered that before they sold 18650 battery adapters, isn’t it possible now?

This is the rechargeable Li-ion battery from Amazon I use to power my slider:

We are developing a new version of the CAMERA SLIDER.
Basically, the hardware changes, but the electronics, motors, cables … almost 70% of the ancillary elements are the same.
So, if you have created the original CAMERA slider, it will be easy to create this one.

We have moved to smoother STEPPER MOTOR DRIVERS (Stepstick TMC2208) too. We will post everything as soon as we test everything 200%.

The control APP will be the same.

I just finished to mount the new rail version. However I am using the old version of the Devia board: the rotation of the platform is inadequate as the new pulley is larger than on the old system.

Is there a suitable version of the code to be injected into the old Devia version which takes into account the modification of the platform and pulley?

Many thanks!

I have the original camera slider that came with a brain shield mounted on an arduino. Looking to upgrade to v2. Can I assume that I don’t need to replace the arduino/brain shield combo with a Devia board?

Thanks!!

I did it. It works but but the rotation of the camera is distorted because the dimension of the plate and the drive pulley are different in the new version … I think that this problem can be corrected by a simple modification of the code. For now, JJRobots still has not confirmed the release of a modified code for the old system (Leonardo + brain).

Thanks Berlib for the update, that is good to know.
