3D printed footplate mod for i1IO v1 to fit i1pro2

The i1io from xrite is a wonderful machine for printmakers. It is basically a robotic arm which holds the i1pro spectrophotometer and automatically takes readings of color patch charts.
Making good printer/paper profiles is time consuming work, and to do that, we have to go beyond the 912 patch chart provided by basic i1match packages. I generally use charts that are over 3000 patches in order to build a good profile, and trying to hand scan them line by line with the basic slider provided with the spectrophotometer will take up a lot of time.
So what the i1io does is it holds the spectro at the end of its arm, and does the the sliding/scanning for me in a quick and precise manner, saving me a whole load of time and swearing (errors happens when you scan manually, either going too fast or too slow).

Basically I’ve been using the i1io for about 1 year before the i1pro2 came out. Due to certain hardware changes, the i1pro2 wasn’t able to fit the foot plate. And Xrite wants a shitload of money to make a small plastic upgrade (they told me the circuitboard had to be replaced too, which I thought was bullshit), plus shipping the entire i1io around will cost another bomb. So I searched around a bit to see what other solutions are on the net.
First promising link turned out to be a hack done by Argyll CMS founder Graeme Gill. It also turns out that it’s the ONLY option around.

For a week or so I was seriously contemplating to break out my dremel and make the cut, then it suddenly dawned on me since I had 2 3D printers in the office, I might as well make a totally new footplate. #hack :]

After a bit of measurements and about 6 prototypes, I ended up with one that fits well and is structurally strong enough to support the spectro.
Here’s the final version

Finished printing



The black patches are thick PTFE stickers to raise the plate slightly and make it glide around without scratching the charts.

I’m embarrassed to even mention this but I’ve no choice but to do so or risk losing the motivation to share and give back to the community due to unscrupulous pigs.
*update2* still way too many folks ripping off my page without so much as a word of thanks. So I’m taking the file down.
If you like my efforts and would like to donate as a form of appreciation, here’s the link. Thank you! 😉

*update 13-10-2014*
I’ve signed up with shapeways and made the print available there for anyone who wants to try their hand at retrofitting their i1io.
They make pretty good prints and are fast in delivery so I hope it works for everyone. 🙂

    Very nice design, How do you support USB plug? I have not opened ours yet but it seems your design is missing that support. I would be also very gratefully if you could post/send me your design (STL).
    Regards Andrej

    I bought the 3D printed base and mounted on my old i1io table. It works very well. I now want to measure in M1 so I need to update the firmware to version 1.07 but it is not allowing me to do that.

    Great job for the 3d design but how can I trick it to update because it is saying seriel number is not supported.

      Hey Nawar,
      I’m really not sure how to trick the updater because my i1io was able to be updated without much issues. When I was on 1.06, I just use spot measures on the io. It takes a bit longer but still works well.

  3. Hi James,

    First off: thanks loads for your design. I ordered the part and mounted it on my i1io without any hassle. Only tip i have: place the bottom arm cover back so the spring arm doesn’t stuck when lifting the i1pro2 out of your new holder. To do this you need to cut out the small plastic lip.

    Hi, James. Huge thanks for You work on creating a good-working model. I’m going to upgrade my existing iO rev 2 with i1pro2 soon. Is it possible to receive an .stl file for the footplate to print it by myself? Thanks in advance.

    With great respect, Dmitry.

  5. Hi there, James, thanks very much for the 3D design. Great work!
    What I ran into was that my measuring head ran against the paper so the iO got stuck. I could solve this by attaching a piece of self-adhesive film on the inside of the ring so that the measuring head is slightly higher. I measured the first profile last night and worked great!

    Greating from the Netherlands,

    Hello mate! Thank you for this great job. How can i contact you? I have some suggestions of improvements.

    HI James, Have you looked at a footplate for the i1 Pro3 ?
    of course it is different from the Pro2 and not upgradable.
    Now that the Pro2 is disco-ed, more people like me will be lokking for one.
    Let me know if you are working on something.

    Thank You.

  8. Hi James,
    First of all, thanks for your great work!
    I also ran into the problem that the head ran aiganst the paper.
    But I found a very easy fix that works like a charm.
    I mounted the original slightly shepre white disk of the i1Pro footplate (which is only held by a spring), with 3 tiny balls of putty, wich is very easy to removed when the device is needed otherwise.
    Then I tightened the i1Pro 2 to the footplate with ordinary tape, that raised the footplate just enough to lift it (about 1 mm).
    The whole arm is now resting on the original white disk, which is very smooth, in fact just like it is when the i1Pro1 is used.
    It runs very nice.
    Maybe you can look into a way to implement the original white disk in the footplate design.
    If you could make a cutout in the design where you can mount/glue in the disk, the footplate would be perfect.
    Again, I am already very happy with the way it is now!

    Thanks, Erik
