UM3 problem and workaround

Recommended Posts

Hello Everyone.

First congratulations to Ultimaker for making a machine that got me to buy another printer even though I wasn't planning too.

I ran into two problems initially and have one recommendation.

I received my new UM3ext late yesterday and had a bit of trouble initially with the lifting function not lining up with the lifting bracket. Sure I could have recalibrated the position but I noticed the gantry was not square. After squaring up the gantry the lifting is working correctly now.

I suspect pulleys slipped on the shaft or wasn't tightened fully. This type of problem is one I see frequently especially on newly assembled machines (we have 20 UM type machines at the moment) and believe the setscrew arrangement is not ideal for how its being used.

My recomendation: This type pulley (http://www.sdp-si.com/products/Fairloc/index.php) has superior clammping ability on hardend shafts and may prevent this type of problem. Just my 2 cents.

After I had the gantry aligned I finished setting up the machine and started a job. About an hour or so into the job, WiFi stopped working but the job did not stop. I ended up stopping the job due to a position issue unrelated to the machine and in an attempt to bring wifi back up, I shutdown the system intending to restart. Well when I attempted to restart, the system would not post (my assumption since there was no display or wifi active). After sleeping on the problem and reading the "Inside the UM3" thread (freaking great having that online btw) I open the linux board cover and pulled off the wifi card.

System will now boot up.

To confirm the wifi card is in fact the issue I installed it and the system goes back to the no boot state.

Still, even with these problems I enjoy having open source type components and an active forum with loads of technical information much of which supplied by sources inside the company. A very distinct difference compared to Formlabs machines which are a black box and have virtually no information from insiders.

Keep it up, love you guys/gals.

Awesome to hear um3s are shipped out already, shame to hear about the gantry, let's hope it is a one of a kind.

As for WiFi, instinctively I would print USB or ethernet due to WiFi sensitivity, but your problem sounds different.

I think @nallath or @daid will be interested in some log files to solve the problem :)

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
