Print suddenly 'stops' (SD) no warnings, no errors.

Recommended Posts

Very weird my old umo+ (1 year and 2 months) started yesterday to do this weird stuff. Printing a job file that I have print probably 50-60 times started to suddenly stop at layer 2-3-5 no warning, no error. And even more weird, the temps move to 0 (lucky me). It's like if the printer resets. But also it doesn't since the leds are still on...

I thought was an sd read error so today generated the sd files from scratch and used a brand new sd card. And again, 6 jobs failed. My newest umo+ works perfect (so lucky me I can still print). But this it's freaking me out. I need to print stuff for 2-3h (not really long jobs) and I can't keep wasting faberdashery.

I haven't move cables, or anything for a month... And I seen this behavior sometimes if I moved the ulticontroller (the cables are well in and in perfect condition). Maybe it's wires crosstalk? If so, what can I do to really isolate the cables?

I have an oscilloscope, can I use that to read the crosstalk? I should stop buying stuff that I don't know how to use...

      Q: For some users, abrasive materials may be a new subject matter. Can you explain what it is that makes a material abrasive when you are not sure which print core to use?
      A: Materials which are hard in a solid piece (like metals, ceramics and carbon fibers) will generally also wear down the nozzle. In general one should assume...

    • "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.
