Ok… I will call this printer LoWBoT… it is cool or not?
That’s running fast for a Prusa-style printer…
I don’t understand why you would drop support for the Z axis? The prusa-style is flimsy enough as it is. IMHO it’s silly to save money on this part of the mechanical design.
Why I should have a Z support if don’t need… i spend some time to find the right solution and work perfectly like this… actually to good for a such printer. Beyond my expectations
Ok then print something tall at 60 mm/s and use moderate acceleration (3000 mm/s^2) on the X axis. If you do not see extra artifacts due to the unsupported Z axis I will be suprised 
BTW: I really like how you mounted the extruder, it’s very nice and balanced.
you might be on to something here. It looks like the feeder extruder nema balances the x drive nema on the x axis. Does the gantry stay level over time? Mine doesn’t which lead to recalibration.
Z have only one motor. Use a belt to transfer the rotation from one side to another. So no leveling problem… never.
@Oystein_Krog ok… I will make a test… this from images is the very first prototype…
That’s a great solution but have never seen it implemented. Have you published any of the models or design online? I’m curious to see how it hangs together.
very interesting take on the prusa layout. am i wrong or is the z belt in horizontal configuration? did you then use bevel gears or am i way off here? would love to see some design files for this - it’s a very interesting one!
it was not a very huge efort to design this printer…(one month of Solidworks ) so i will release the design files when i will have the time to post somewhere
