LongMill Build Time

Hi folks,
As promised, I documented my build time for each section so I could add up the totals. This is my first attempt assembling this type of CNC. My previous experience is with a 3018 Prover.
Link to my 3018 (https://youtu.be/svj7zPuYvos) Small flimsy machine compared to the Longmill !!

I show a completed page number and time for that section from previous completed page.

Unboxing up to completion of

Completed mechanical assembly Total to this point 6hrs 35min
I didn’t time my chains and wiring, but I would say about 60-90 minutes. I wasted lots of time learning how the chains work. After wiring, I did axis tests. All seem OK.

So total time about 7 1/2 hrs. I still need to mount this on my table and install my MDF strips and tracks.

I have contacted Sienci Labs about my bad parts (also had 2 bad anti-backlash nuts). I haven’t heard back yet but I don’t think it will be a problem. I hear great things about their customer service.





Sienci Labs responded quickly and are sending me replacements for my bad parts. Already shipped!

These guys are good.

Later y’all,
