This will give me the advantage of being able to load the stl to be printed into ram that is directly accessible by the machine and not via the USB connection to the PC, I have read that this greatly improves quality as however smoothly you think your printer is printing trust me it is not as smooth as it could be if you were printing directly from ram, I am of the understanding that this can completely remove the surface digital artifacts that appear on some larger prints as these are caused by delays in the PC communicating with the printer via USB, I proved this quite effectively by just loading several other applications on my PC during a print and more or less immediately the printer starts stuttering whilst It waits for the next packet to arrive over the USB connection.
Can’t wait to get this working.
At the same time I will be implementing the Bowden extruder mods to give me that extra build height I so desperately need to complete the Savonius & Gorlov VAWT.
I have also been formulating a plan for a major mod to the prusa that will incorporate a ABP (Automated Build Platform)
I am thinking of a design that incorporates the Y axis as an ABP, I am hoping that the addition of a couple of aluminium tubes with printed skate bearing holders at each end (4 bearing’s in total) will allow me to use the Y axis motor as the ABP motor allowing the ejection of finished parts using a simple Gcode sent as the last line of Gcode in any particular part printed.
That Gcode will simply rotate the whole build surface by one complete revolution, there would be a requirement for no max end stop to be present on the Y axis and it would also remove the need for a Y axis drive belt (as the build belt would become the drive belt.
The printed tube ends would be studded with teeth much like an old 8mm film projector and the build belt would be peppered with a row of holes that would mesh with these teeth.
There are obviously a lot of technical details to iron out but I think this would be a significant advancement over the existing ABS’s that seem to bolt onto the build plate and require an additional motor/electronics for ejection.
