Bed Leveling
I have gone through all of my calibrations, but for some reason different parts of the bed do not print at the same level. For example, in the attached image, the ring without holes printed a perfect first layer, but the ring with holes(close to the logo) printed with the nozzle too close to the build plate, and is rough. Also, the support first layer in the middle is rough, but it is clean on the left side of the build plate. It is also clean farther back on the build plate. How can I make the first layer more consistent?
Re: Bed Leveling
1. make sure you're giving the bed and the sensor plenty of time to preheat before starting the print&mesh leveling. temperature of the sensor will change its response as the heatsink slowly heats up. The bed will change its shape as well as the response of the probe points.
2. print and use some variation of these in addition to the mesh correction menu https://www.thingiverse.com/thing:2780118
Re: Bed Leveling
Read this about higher density mesh bed levelling.
https://github.com/prusa3d/Prusa-Firmware/issues/1239
Then use the modified firmware if you like. I spent over a month stripping down, rebuilding, measuring, adjusting, fitting springs etc to try to get a consistent first layer over the whole bed, eventually found the above github page and have not looked back since.
If your not happy flashing firmware from unknown sources then, at the end, there is mention PRUSA are releasing the next firmware with 7x7 or even 9x9 mesh bed levelling built in, just like in the discussion and firmware from the above.
Hope this helps.
Normal people believe that if it ain’t broke, don’t fix it. Engineers believe that if it ain’t broke, it doesn’t have enough features yet.

Oh, and get yourself one of these:

Ideal for scraping of first layers without wrecking your bed surface, should be standard with every printer in my opinion.
