  1. On the smaller guide rod going front to back, the one where the black block holds the rod upside down....the rod is falling out/rocking back and forth. I guess I need a couple new black mounting blocks?
  2. Thank you for the feedback guys! After removing the prints, there was enough z shift that I could just peal off the section with ease. easier than supports lol. with that said the more towards the front of the printer, the larger the z gap, which means that the bed was leaning forward a good bit. I also noted that it seemed to be an issue between bottom layers section and the rest of the body. the top layers were also not right, but it was not a z issue, just seems to be shifted in the X or Y (not sure which). I will upload proof of that where a hex was printed, the pics are adjacent side
  3. Facts: I have not changed any speed/feed/material settings. Printer is now intermittently seeming to lose steps. A few days ago it printed and looks like in the front to back axis it lost a good number of steps and shifted the whole print forward between 1 and 2mm. yesterday it seems to have dropped the build plate too far by at least that amount. Oddly, the front of the print is significantly more gaped between layers (so the build plate is leaning forward? I have no idea how many print hours are on this machine, the printer does not store that kind of data. My guess is that the increased h
  4. Yeah, not super happy about the response from BASF...to put it lightly. fair to the advice. I would say the same. If I can find a = or better material out there for this use case, I would switch. Fingers crossed, because I do like keeping the printer on its native material thickness. I have not heard of the LUVOCOM stuff. Please let me know where you get it from and how it works! Impressive that they say it works for material station, I didn't think any chopped materials worked in the material station. I have another U5 with material station doing all our "regular work"
  5. I am having similar issues. I changed to a 1.75mm material, changed machine settings to 1.7 (actual material size) and it seems to extrude same rate as 2.85mm without changing flow. I also tried changing material to 1.7mm, did not seem to change anything. prints were not printing hardly. Ended up boosting flow to 235% and that seems to have fixed it? but its a really dumb game to play. I wish I could just change the material size and it adjust everything needed to match. Seems like Ultimaker Cura is over-riding this setting? I have an S5
  6. so, I actually contacted BASF about this issue. They said that they get complaints all the time about the 2.8xmm CF15....and what was shocking is that they had no solution, in fact they said to let them know if I found one? lol, whatever. not here for what I think about that 😄 I honestly think it has a lot more to do with the composition of how they are making the PAHT. Its highly modified Nylon, higher temp resistance and far less subject to moisture, but this makes it super stiff stuff. Like, right now we are getting crazy performance from it. we put it in a soap mixing/making applicati
  7. I doubt it will ever work with the material station. It is by BASF. The material is so stiff it already has lots of snapping issues in the feeder. The bowden tubes also can move a lot due to how stiff the material is. I would imagine this could greatly impact the material stations method of feeding. I could be wrong.
  8. Any other thoughts? For now I am going to try and re spool the material into a much larger spool so that the radius is larger. this stuff is so so stiff and brittle. I tried heating it up to 200f and it was able to bend to about 5 degrees before snapping. Its almost like it needs an inline heater to bring it up to 250f before it goes into the feeders (both the feeder behind the machine on an S5, and the hot end.)
  9. Truth. In regards to generic materials, I think Cura should have a check mark for switching materials on empty. Give the programmer the control. Another note in regards to material station, it only works with a small group of materials. It will not work on materials I use a lot of like PAHT CF15. If my machine could switch to another spool without the material station, I could run larger prints with such materials much easier.
  10. The machine already knows when it runs out and what material is in the other extruder...the code already mostly exists (if not completely) from material station firmware...why not just have the machine auto switch on run out? why complicate with calculating spool run out or use a helper volume?
  11. The material is new, the feeder is not too tight from what I can tell. It did fine for the first half of the roll, but it seems now that the material is snapping when the feeder forces it more strait because the material on the spool has a smaller radius as the spool gets lower and lower? I keep my spools in a sub 15% humidity room, but the room is also my print room and so it gets hot, between 95 and 100F normally. I dont generally have a spool for more than a month. The BASF PAHT CF15 that is giving me issues I have had for less than 2 weeks. again, it did about half the roll with no issues.
  12. Anyone have thoughts or work arounds?
