  1. I've been having this problem recently myself, started with new version of cura. Not sure if it's the same issue, new files I've been slicing are starting the z height higher then it should be, and not squishing the layers properly. Printing old files indicates it's a slicer issue (the old files print fine). I don't have a solution yet, but figured I would mention it as I look for a solution, if you have any suggestions.
  2. When I started using 3.1, and later 3.2, I started having similar issues, I had very little stringing problems beforehand, and with each updated version of cura it seems to get worse. I use a Prusa mk2, recently replaced my nozzle and whatnot (after the issue started). I have a whole bunch of old g code files to print, which have no issues. It only occurs on new ones.
  3. Thank you so much for responding, It's set to zero. After making sure I tried printing it to see if I had it set to something else for some reason beforehand and it had the same issue. It's technically a different model, but it's very similar/different iteration from the same file. I tried resetting all my slicing properties as well in case I screwed something up, which didn't help. I think I used 2.6 or something around that for the old version, and I am currently using 3.2.1. I started having this issue with 3.1, and I thought I had sorted it out but it came back with a vengeance, and I had just brute forced it before to get it to work, didn't actually solve the issue. I can ultimately compensate for it with live z adjustment but it's clearly setting the zero higher when I am slicing new files compared to the old ones. (If I try printing an old file afterwards the nozzle hits the bed). Also I'm printing on a prusa mk2. I don't believe the solution is in the printer profile, but I don't have enough experience to really know. Looking at the gcode, it's setting the right heights, just starting high for some reason.
  4. I've been having the same issue. I'm trying to ask questions but don't seem to be getting any responses
  5. I have been having some issues with layer heights recently, some with under extrusion on all layers, but particularly with first layer height issues. When I slice with cura I noticed that the first layer was about 2mm above the bed and I have no idea why. I re calibrated the printer, and printed an old profile/gcode which worked perfectly fine, but anything new doesn't work. Any suggestions?
  6. I recently downloaded the new version of Cura (3.1) after putting it off for a while. After doing so I started having an issue when my printer changes layers, where it looks like it's not completing the layer or its under or over extruding in these areas as the Z axis moves. I don't have a picture of this at the moment but can get one if needed. As part of trouble shooting I went back and printed some old G code files I had to see if it was the printer, but that defect didn't appear in these prints. I then I started printing some cubes using Cura 3.1 to see what the issue is, and it looks like the printer is pulling the plastic up whenever the layer changes. It always occurs at the same point at the print and at the completion of the layer. I tried messing with the retraction settings, but because I did not start getting this issue until using the new version of Cura I feel like it has to do with a change in how the slicer works. Does anyone have any suggestion as to what this might be, or how to fix it? I apologize if it's hard to see in the pictures.
