Some people were asking why they should switch to Marlin? Here’s a perfect reason why: http://www.youtube.com/watch?v=x8eqSQNAyro
Especially, say if you maybe want to build kits to sell or anything - pairing up with an autoleveling feature would make your users very very happy.
I would love to get into this hobby… I just don’t have the time for it.
This is fantastic. I was playing with doing just this sort of thing a year ago, but shelved the project because I could not measure the bed height accurately.
I am going to have to try this out now.
An excellent piece of work, I would love to add this to my Prusa. I am glad your software/hardware expertise is better than your camera skills 
well done.
Fantastic… well done. Look forward to see how it is done…
What do i need to mount the autobedleveling feature? Is there any blog entry?
@ThantiK do you know if Alex has posted his code up on github some where? Looks like an easy upgrade if you’e got the servo laying around.
It looks like his code was the last to be committed to the marlin_v1 branch.
This alone would make Marlin worth it.
Is this something that could be done manually, without the servo? I would love to just use jog controls to touch the nozzle to the bed at different points and have it accept those as the points on the plane.
Is there a printable version of the servo mount anywhere, I can’t find anything on thingiverse. Once that is setup I think configuring Marlin should be quite easy.
@Geoff_Drake , this is pretty cutting-edge at the moment I think. Was just merged into mainline marlin. There are probably going to be a lot of different solutions for this.
Gah, the bed IS even. it’s just not tram.
A similar capability was added to Reprap electronics and firmware about 3 years ago by Gavilan Steinman. The levelling probing process was implamented on his DIY milling machine; I wander if he considered adding the levelling probe feature to his 3d printer at the time.
I’m in need of a much lighter build platform and this bed levelling feature is just the ticket.
@Mark_Heywood , Gavilan Steinman used an existing probe script that was not created by him. It was not part of the firmware or electronics, it was a post processing script. This is not the same. The gcode used for this could be used across printers with different characteristics, his cannot.
The script is here: http://phk.freebsd.dk/CncPcb/ - and it was made by Poul-Henning Kamp
Definitely going to try this, perfect tram is the final frontier for my OG Prusa!
@ThantiK The existing probe script by Poul-Henning Kamp was not used, only the levelling concept was used, and ported to the then Reprap software tool chain by Gavilan Steinman.
I only claimed that the capability was similar not its implementation.
Gavilan Has made the files available that includes the firmware and host where the firmware does indeed have the probing routines coded in. The probing information is parsed in to the G-code by the firmware.
Your comment was a bit unfair, making look like I was making claims I clearly did not make.
Thanks for the clarification @Mark_Heywood , my apologies.
@Tony_Olivo I don’t think it would be that much work to even just manually move the end stop with something simple to move it back and forth. Just manually put it into position and then manually retract it.
@Ross_Hendrickson maybe I didn’t understand, was he just reusing the Z endstop?
