@unixb0y Thanks! Will check them out later! 😀

@unixb0y Any tips for "bed leveling? Find this part hard to achieve / feel.
unixb0y Dave
@runeranch A few tips: • check with calipers that your X axis is level with the table (if you have dual Z motors with lead screws • screw the heatbed in pretty tightly and try to count the turns so they’re roughly even [1/2]
unixb0y Dave
@runeranch [2/2] • manually move the nozzle down until it almost touches the bed, then use the “paper sheet” method • in General: first try to get it roughly level, then do the fine tuning afterwards.
unixb0y Dave
@runeranch which printer do you have?
runeranch Rune Ranch
@unixb0y CR-10s.
unixb0y Dave
@runeranch nice. Afaik it’s single Z motor so it’s probable that the right side of the X axis is a mm down; you’ll have to compensate for that with the bed levelling otherwise your prints will get too loose on the left and too squashed on the right :)
runeranch Rune Ranch
@unixb0y No, it seem to have two motors (blocks) on both sides of Z axis? It's this model: CR-10S - S3 [3deksperten.dk]. Should I adjust both Z axis so they both down and adjust from there?

@runeranch ok then try that. The X axis should be level in the first place. As I said I usually measure the distance from the X axis to the table along the Y axis on both sides with calipers and manually turn the motor shafts with the printer turned off

@unixb0y It’s rather a hit or miss for me so far. It comes down to the first layer. Nuzzle seems to scrape the previous layer off or due to filler remains stuck on the nuzzle. I’ve used about 5 hours today adjusting bed leveling and with little results.
runeranch Rune Ranch
@unixb0y The printer has a auto bed leveling function. And I use the paper method for adjusting. I find this method hard. How much resistance should I allow on the paper under the nuzzle? 😏
unixb0y Dave
@runeranch sure it comes down to the first layer :) https://youtu.be/Fo42S22BTwg https://youtu.be/L6GJWHwrTmY https://youtu.be/eOjDVSXg3Oo
unixb0y Dave
@runeranch right, but still a good base calibration is essential. The paper should barely touch, just level it until you can barely feel some resistance.
runeranch Rune Ranch
@unixb0y Okay. Also this might be me running the PLA at too high a temperature (200*). But is the PLA suppose to be running slowly out of the nuzzle when heated? This have ruined my first layer several times and makes it hard to adjust the bed.
unixb0y Dave
@runeranch no no don't worry I print PLA at 215, that makes no real difference for layer adhesion. Yeah sure it oozes out a bit because it's a bowden setup. You have to take that stuff away just before it starts printing with some pliers.
unixb0y Dave
@runeranch Also make sure your heater block stays clean so the PLA doesn't curl up and stick to the heater block or nozzle. You'll want it to be all clean
runeranch Rune Ranch
@unixb0y Yeah I’ve seen that it likes to crawl up the nuzzle. How do you clean that area?
unixb0y Dave
@runeranch with my Leatherman pliers :)
