Hi
There was a question here about bed leveling and then it went away ... hmmm ...
Manual bed leveling seems to work very well on this machine. Servo bed leveling has issues with servos and temperature. Inductive bed leveling zeros to the pc board under the glass. Either way, the automatic approach has issues on a "stock" machine. I suppose you could glue tin foil to the back of the glass ... sounds like a pain ...

Hi Bob,
That was my question. I deleted it because I realized that the video answered my question. Thanks for your input though. I have a lot of things to learn before I venture into modding a machine like that.

Hi
On a lot of the early machines, holding a "zero bed" was a real pain. Some of that was related to the materials being used in the printers themselves. Some of it was process induced. The "old way" to run a glass plate machine was to swap plates with each print. You let the part cool down on the plate while you printed on a new one. Turns out that the thickness and flatness of cheap glass isn't all that terrific. The "new way" is to just leave the same piece of glass in place all the time. Let the part cool down on the printer. Pop it off the glass and move on. It might add a couple of minutes to a print that takes a half hour to do. If you go back a couple of years, you will find a bunch of posts from a guy named Bob talking about the need for auto bed leveling. Obviously my view has changed as printers have gotten better and we've learned things.

I'm using an 8mm inductive probe on a Pegasus 10 and it works great. It senses the PSB at about 5mm which leaves me about 3mm clearance between the probe and the print surface. Once I got the offset tweaked it
s been spot on ever since (about 3 weeks) A 4mm probe isn't going to work without some more metal below it.
Has anyone seen Prusa's new ABL setup that also measures and compensates for any skew in the x/y axises?
Please explain to me how to...
