The first layers are ok now, but I started to run onto the delamination issues when printing was progressing. I also changed the bed temperature back to 50 degrees, since the glue of a second sticker started to bubble. Printing temperature is still at 205 degrees and fan speed is at 100% (as recommended by Cura) Should I give the auto bed leveling a try once again?

And when you think it's all good, my heatbed sticker starts to bubble Great... now I do have something to do tomorrow

I redid the whole calibration thing, including a failsafe setting restore of my print settings. I am 10 minutes into a print and it looks better than the previous ones. Might be because the failsafe settings let the head move a little slower I'll keep you updated EDIT: I am pretty pleased with the result of this print! I'll print a few more things and I'll let you know if the issue is fixed

I've got the feeling that the plastic is cooling down to quick or something. When printing the first layer, the first layer thickness seems to increase as the printing progresses. That is the moment when the rippeling starts and eventually when the print releases from the bed, which is a new thing to me. Could it be that the auto level data is invalid or something? EDIT: I noticed that one side of the nozzle is very dirty (full of molten plastic) could that cause the rippling? The side that starts to ripple first, is the side that the molten plastic is at. I've included some new photos of a full first layer, after I removed loads of warping brim.

I will! With the paper method, what is it that I am looking for? A bit of resistance or total stop of movement of the paper?

The printer has already been upgraded with what I think are quite some good stability upgrades. Below you can find some photos of the upgrades I currently have installed. I also installed Marlin Skynet3D V2.3.2 to allow the autolevel sensor to work properly I'd love to print new upgrades for my printer, but I first need to get it to properly print again. The result is basically the same as in the first post, but less worse

I installed some new heatbed adjustment screws and springs and it works much better now. It still has some warping though. I ran the G29 command 3 times, and the output of each autolevel sequence is a little different First level: Second level: Third level: I do notice that there is a correction coefficient of around 1 in the diagonal, but I'm not sure which points correspond to that. I have calibrated and leveled the bed 5 or 6 times now and it got better but I am now at the point that it doesn't get better anymore. Could it be my printer itself? Dirt and dust on the axis, microstuttering when moving or just a bed that is not flat?

I spoke to soon! Serial connection to the printer got lost and the printing stopped. ? I am using PLA and the new print (and the one that lost it's connection) used 205 degrees at the nozzle and 50 at the bed. I am printing from the SD card right now, that print that went wrong was the first and last Serial print for me.

I've recalibrated it and it seems to be a bit better. I tried 185 degrees for the nozzle and 60 degrees for the bed, printed using Pronterface instead of the SD card A few weeks ago, I also noticed that my heatbed springs are not optimal so I ordered new ones and I expect them to arrive in a week or so. I started to print something for the 8th time today, and it kind off worked. When the first layer is good and doesn't warp, until know (knock on wood) the printing goes fine! Do you have any future tips for calibrating the printer? I need to do that when the new heatbed screws arrive

These are the settings that I am using Anet A6 with auto level upgrade PLA Nozzle: 205 degrees Heatbed: 50 degrees

I've been printing alot with my Anet A6. Upgrades, upgrades and more upgrades. They went very well until I needed to replace the filament, I tried to do that whilest the printer was printing, bad idea. Things went wrong big time and when I finally got the filament in the nozzle again the printer wasn't printing properly anymore. The nozzle slammed into the sticker on the printbed a few times, pushing the heatbed down with full force. I've replaced the nozzle, because the .4mm hole was C shaped, the shoulder piece of the printer (I slammed it) and the heatbed stickers. I calibrated the printer by autohoming, lowering the Z axis until a piece of paper was tight and then entering that value as the new Z-offset. That didn't work out as expected, so I started to print dry, leaving the filament outside of the printhead. Using that method I reached the paper tightness I wanted. I felt like my printer was going to print again! However, 4 or 5 hours later, I was proved wrong. When printing something, the Cura adhesion improvement layers start at the outside and slowly move to the inwards. When moving to the inside more and more, the layers start to curl and bend and when continuing to print, they come lose from the heatbed and the nozzle will drag the already printed parts everywhere. I've tried various things, add hairspray to the heatbed, recalibrate the nozzle distance, in- and decreasing the nozzle and heatbed temperatures by 5 and 10 degrees, decreasing the print speed, reslicing the model. I am litterally about to throw the damn thing out of my window. Could anybody help me?
