Love the video! I’m just wondering when you have 2 springs in each section, (for example 2 blues down the bottom) how do you go about tuning the tension? For example do you adjust the tension evenly, or do you do one spring up all the way and have the other looser? If so, do you adjust the upper bones or lower bones first?
Each section of the arm is independent of the other. If you only have two blue springs on the bottom of each section then the tension is based on how much lift is needed. If only one section can not hold the weight then only that spring is moved up to the upper part of the arm. Cheers Taj
Hello, I have a question regarding deciding what springs to use and xtune configuration. To start with, i have the chimera one, which is already 5.5Kg / monitor 1.5kg/ counter ballance 2.5kg / and at least 1 vmount for the volt under the sled 1kg / and 2 more for the camera each 1kg. the total weight before the adding the camera setup is already about 13Kg Adding the camera setup about 10kg shooting with the alexa 35 ( 3kg ) - adding focus motor / mattebox / transmitter - lenses Cooke s4i( between 1.5kg /2.7kg) Total is about 23kg let's say. In smartsystems arm X1 weight chart it shows upper ones both blue and lower ones both black ( this setup covers between 21kg and 27kg ) 4 blue springs reaches 21kg. My question is, with these weights technically this is the correct springs installed correct? and how do i decide the xtune on the 4 seperate springs with this setup? thank you in advance and sorry for the extremely long comment
That chart is a good starting point. However, I found that sometimes using different spring combinations based on load capabilities of each bone gives you a more iso feeling.
@@tajtcam I usually do all blue to have a lot of range, but my springs are barely loaded unless needed, sounds like I should change it so I can max out my springs more?
Wouldn't this type of arm with 4 bones require the springs of each section to be on opposite sides? As in, one section has a top spring, the other section has a bottom spring, and vice versa.
Can you use any spring? Or do they have to be specific? Im currently building a DIY arm and have been trying to figure that out along with the mechanism that tightens the spring
@@tajtcam that’s what I ended up doing! Thank you so much! Do you have to put the screws back in the bottom when it’s empty or you don’t need to, takes a sec to put them in when there is no screw.
This has been the most useful video on ArmX1.
Thank you for making it.
Love the video!

the total weight before the adding the camera setup is already about 13Kg
Adding the camera setup about 10kg
shooting with the alexa 35 ( 3kg )
- adding focus motor / mattebox / transmitter
- lenses Cooke s4i( between 1.5kg /2.7kg)
Total is about 23kg let's say.
In smartsystems arm X1 weight chart it shows upper ones both blue and lower ones both black ( this setup covers between 21kg and 27kg )
4 blue springs reaches 21kg.

Really usefoul, but how much do you load the springs before step on the next color or move to the upper bone?
I feel like these springs work best when fully loaded. I take them all the way before I change them out.
@@tajtcam yes I agree, I’m still tryin’ to find the most isometric setup for my one. The result is so better whit your method aniway 👍🏿

In my experience this has not been the case. I have been able to mix and match any spring to any bone section of the arm.

You need compression springs. Cheers Taj
@@tajtcam thank you sir!!!!
What springs do you typically use for an Alexa mini build with a small lens?
Two black springs on upper arm sections

@@user-ho9yk2wt6c you can run without the screws back in. I always put them in to not lose them.
@@tajtcam thanks! You just helped me so much!!!
@@user-ho9yk2wt6c any time, cheers
