anyone here fixed that problem? i have the same... left side the print not stucked.. right side just fine...
didn't found the problem... :( Obvious answer if things were running ok in the past is to run Calibrate Z to ensure your X-Axis didn't get accidentally moved, the pre-print Calibrate Z will attempt to compensate for a small offset, but it never huts to ensure "squareness" by simply running a Calibrate Z to ram the X to the top to force it straight...

Hope that helps, but you should also make sure you're running a new firmware if you haven't upgraded in a while, lots of improvements in 3.5.1!]]> Assembly and first prints troubleshooting LA 3D Printer Repair https://forum.prusa3d.com/forum/original-prusa-i3-mk3s-mk3-assembly-and-first-prints-troubleshooting/prusa-i3-mk3-kit-first-layer-calibration-issues-and-uneven-printing/#post-121086 https://forum.prusa3d.com/forum/original-prusa-i3-mk3s-mk3-assembly-and-first-prints-troubleshooting/prusa-i3-mk3-kit-first-layer-calibration-issues-and-uneven-printing/#post-120885 Wed, 19 Dec 2018 22:25:04 +0000 anyone here fixed that problem? i have the same... left side the print not stucked.. right side just fine...

This exactly describes the issues I am having with my Mk3. I would encourage anyone having similar issues to read the entire post (link below). Hopefully, Prusa will implement the firmware changes quickly.

This is a big issue for me as well. I have all settings set to zero except for back which is maxed out at +50 and the print didn't change at all. Try doing a "Factory Reset" -> "Delete all Data"

Then re-do the XYZ calibration, and the Live Z adjustments.

I had a case where something was corrupted in data, and it made the Live Z not work correctly - I am guessing it was mesh correcting strange.]]> Assembly and first prints troubleshooting AJS https://forum.prusa3d.com/forum/original-prusa-i3-mk3s-mk3-assembly-and-first-prints-troubleshooting/prusa-i3-mk3-kit-first-layer-calibration-issues-and-uneven-printing/#post-70695 https://forum.prusa3d.com/forum/original-prusa-i3-mk3s-mk3-assembly-and-first-prints-troubleshooting/prusa-i3-mk3-kit-first-layer-calibration-issues-and-uneven-printing/#post-70428 Fri, 09 Mar 2018 10:35:20 +0000 I’m away on business but brought my printer to kill time.

I installed the firmware as you recommended and followed the instructions on how to complete the hyperfine calibration. However, it did not solve my issue. Each time the mesh leveling routine occurs, the Z axis offset and bed leveling correction requires adjustment.

Here are the instructions I followed:https://shop.prusa3d.com/forum/prusa-i3-kit-building-calibrating-first-print-main-f6/hyperfine-bed-leveling--t4330-s110.html#p41311

During my first attempt, once I printed a perfect center circle, I continued per the instructions for the rest of the gcode squares. After I dialed in each location, I adjusted the bed level correction. Then, I printed the "All" gcode which prints the center circle and all of the squares. Before this printed, I performed a mesh bed level. After the calibration, the center circle did not print correctly and the "A" square did not adhere to the print bed and the PLA attached itself to the nozzle.

My original Z offset from my first calibration mentioned above was -0.722. I wanted to print several of the center gcode objects without changing any settings to show the issue. I dialed in the center Z offset again and this time it was -0.705. In the picture below, you can see (barely, sorry, the silver PLA is shiny), the first circle printed as close to perfect as I can get. The other three circles were printed a short time later in quick succession, and as you can see, they printed a little different each time.

When you print any of the calibration gcodes, it raises the Z Axis to 100 mm, so I do not think it's the PINDA thermal issue I've read about, although I do think the PINDA probe may be at fault.

Again, any suggestions would be appreciated.]]> Assembly and first prints troubleshooting Darrel https://forum.prusa3d.com/forum/original-prusa-i3-mk3s-mk3-assembly-and-first-prints-troubleshooting/prusa-i3-mk3-kit-first-layer-calibration-issues-and-uneven-printing/#post-69927 https://forum.prusa3d.com/forum/original-prusa-i3-mk3s-mk3-assembly-and-first-prints-troubleshooting/prusa-i3-mk3-kit-first-layer-calibration-issues-and-uneven-printing/#post-68819 Thu, 01 Mar 2018 20:19:33 +0000 I went through a lot of these same issues, although I was able to see a few sections of the bed that were not level. For me, adhesion was never a problem and prints would eventually turn out okay, but first layer quality suffered drastically and was an issue on thin, flat parts.

ultimately I explored two different options:

1 - Flash the Hyperfine firmware and manually tune all cali points instead of trusting mesh leveling. It works, but its a pain.

2 - Accept the lower first layer quality and attempt to tune it out (more base layers, etc). Also, print with a raft or print with lower layer heights (seems much less prone to rippling).

At this point I think I still prefer manual leveling, but mine is printing quite well finally.]]> Assembly and first prints troubleshooting thrawn86 https://forum.prusa3d.com/forum/original-prusa-i3-mk3s-mk3-assembly-and-first-prints-troubleshooting/prusa-i3-mk3-kit-first-layer-calibration-issues-and-uneven-printing/#post-68819
