  1. Along with my recent explorations with the UM3, which fbrc8 has been very helpful with, I had an idea for developing a manual leveling guide which uses the sensors for feedback. After reviewing the api docs, it doesnt appear there is a current api for sending direct gcode commands. I did test the send print job api, but it simply fails reporting bad request or something. 1) Is there an existing API or way we can remotely send gcode commands and receive the output? 2) What are the correct commands to retrieve/set the current leveling information - bed height offset from 0, nozzle z offsets,
  2. SandervG - I have experience at least another instance of the popping noise. Unfortunately I wasnt watching the printer at the time (it sits behind me). Adhesion sheet - This was printing with ABS. Which so far has been a big challenge, a mixture of bed adhesion and severe part warping even using the front enclosure, and adding my own majority-top enclosure. My FFCP does not experience this. Using MH Pro ABS, tested temps 230-260c bed 80-100c with no, or little cooling. Leveling - Well, yes I still get some adhesion issues and/or peeling off the plate, though the quality of my first layers
  3. I received my advanced printing kit. The front enclosure.. leaves much to be desired. Anyhow.. Further frustrations have set in. The adhesion sheets literally glue the part in an inseparable fashion to the bed, and theres no way to get the bubbles out. I removed the sheet and had to soak it in goo-gone for an hour. Back to square one, I was trying to make progress. I disabled auto-leveling, and manually leveled the bed again. Definite improvement. Wanted more still - logged in to the printer via SSH and manually ran G30's to check sensor results around the bed. 20x20 -0.85887200x20 -0.83
  4. SandervG- I posted a few images of my first layer above your post. Here is an additional picture of a few failed first layers, where either the first layer was scarred or the prime tower did not adhere and got dragged into the print. Using both default and custom cura profiles, testing different temperatures, retraction settings and so forth. Regarding first layer, it seems the auto leveling is not doing me much good here. Adhesive I typically print PLA bare glass without issue. I have tried glue, no improvement. I havnt had the popping noise recently, so hoping it is gone or I just ha
  5. Pic of my rather bad stringing, currently at 200c. Default retraction setting and speed. Ill set aside some time to test zhop, retraction distance/speed, and try to lower temps but this still seems worse than it should be. Hmm.
  6. I have tried playing with retraction but still get a bit of the blobs/stringing. Dual extrusion prints also require the prime tower or else there are literally strings of filament hanging off layer change points. Also, I am having issues with my first layers. All of them have partial adhesion issues, like bubbles, which cause issues if the extruder catches them or at minimum leaves a crappy bottom layer. Using ultimaker brand PLA. 60c bed, ~200 temp. Ive played with temps with little success. My attempts at printing ABS have also been failures as the warping without an enclosure is pretty
  7. Thanks for the response. The blog entry is nice to highlight updates, but not a dependable place to put formal change logs. For example, I see there is a preview/unstable firmware available. What specifically is different with it? Any known bugs? Updated my firmware to the latest stable also, cant find a version specific log. Would be very nice to have for reference.
  8. Bumping as I feel this is important. For a product marketed towards prosumers/business the lack of formal change log seems like a large oversight.
  9. After re-re-leveling the bed per the ultimaker.com statement that there should be 14mm between the aluminum plate and the bottom of the glass bed, washing the glass very well, and correcting filament tension I am now able to get prints out more reliably. Also performed a firmware update, and Cura now 9/10 times reports the printer as 'busy' after a print forcing a restart. Ugh. Ive attached some images of them. Most of the prints are done slowly, the rook at maybe 10-20mm/s .1 or .06, dont remember. The owl came out okay, but suffers from blobs and/or other filament color being deposited in
  10. So I've had a few days to play with my new UM3 thanks to the very helpful people at MatterHackers who handled my expedited shipping beautifully. Migrating from a FFCP, which had a few nuances but is a very dependable machine. Thus far my upgrade has been less dreamy than anticipated, with a solid shot of reality. So here's a list of my observations at time of writing.. Loading material, it does not mention to adjust the feeder tension. It defaults to half way, which ground a lot of filament and leaves gnarly bite marks. -- Edit I did have grinding issues, but further reading shows middl
  11. When you first start the leveling, it will ask you to adjust the bed up/down using the wheel on the front of the machine. After this, itll switch to fine adjustment asking you to use the physical bed screws. I went through this last night, ended up doing initial adjustment by manually measuring the aluminum bed floor to the bottom of the heated plate to be as close to 14mm as I could get using a small metal ruler thing, otherwise I think it'd be hard to know where that 14mm would be without measuring.. Then ran bed leveling and did fine adjustment with the screws just to level it out, thi
  12. Third time is the charm.. App stopped working again. I did perform a firmware (stable release) update in the interim.
  13. It does not appear to fit non-UM spools. My MH Pro ABS spool only fits on one direction. I printed a top mounted single spool holder and so far it is serving its purpose for now.
  14. Hey everyone, Just received my UM3. It has been quite the learning experience - some good some bad. For one, it came with the feeder tension too tight and nothing about this in the setup guide. Lots of wasted and ground filament to figure that one out. Anywho.. What is everyone using to hold standard 1kg filament spools? This alone has been a source of frustration so far. For such an expensive machine, it should include a standard size spool. Thank you
  15. Followup - The app now works for me, for some unknown reason. Only changes since have been the installation of a Solex print core which I assume is not relevant.
