SuperDoodle - Design Progress (Page 1 of 2)

That 200mm + print speed may be a hard target to reach on a machine that size. You may need some much bigger motors as running a machine that size at those speeds is going to require tremendous torque to stop and start almost instantly on corners and open places in your print.

I can make my printer do more than 200mm/s and claim it does that. However the print will look like garbage. What they claim and what the results are at those claims or two different and never shown things. There is no agency that governs or confirms the claims of printer manufacturers so some of the claims are out there and simply sells hype. There is a reason most of us even with a well tuned machine still print on average between 60 and 100 mm/s. In some case you have to print even slower. If you use PETG you must print at 35mm/s or less to avoid strings and other problems.

I was thinking about doing something like this to match the original solidoodle design. (as best I could)

VS

Here it is in the with white lettering and green bg

still not really convinced of the need of 3  Z motors, but will wait and see how things progress.

in the original logo, the "Soli" part of Solidoodle is a completely different font... so in keeping with that...

and knowack.. since the workbench is so much larger, what about "Megadoodle"?
LOL

LOL, not sure if I should be offended, or LMAO at this point. =P

but back to the main topic...

not convinced on the need of 3 motors for Z axis..
three Z screws, yeah, maybe... but 3 motors?

keeping 2 motors in sync can be a struggle - 3 could become a nightmare.

But, hey, i am open to new ideas.. convince me!

Not sure if you are joking or serious, but I was joking. Guess I just have a toilet sense of humor and others are less. To me everything is a dirty joke or can be made into one.. Life is just more fun and humorous that way.

Back on topic, I like to build and experiment as much as the next guy, but I prefer using already tried an true methods and I don't feel a need to reinvent the wheel. I will use what has been proven to work. In fact I use only one motor and screw but very heavy 10mm guide rods and an all aluminum build platform with a magnetic glass bed.

This is the Hacks & Mods section of the forum ...

I assumed the three motor idea was to have the motors independently controlled so he could have true auto bed leveling. Because what they call auto-levelling in firmware these days is really assistance with manual levelling or compensation for out of level is it not?. There is no mechanism to actually level the bed.

With three independently driven motors and a probe, it could literally level itself. An actual physical self-leveling system would be innovative would it not?

Personally I still think it's the wrong direction. Aim to build a printer that can be manually levelled and then stays level is how I would go.

However, I'm always interested to see what 2n2r5 gets up to. His threadless ballscrew design drives two of my printers z-axis
to this day though people would swear up and down at the time that it was not a good method.

There is actually. At least with Smoothieware there is. It is a form of active real time leveling during printing.

Smoothie will use a probe either RF, touch, or proximity to map the bed  before each print. It does this by dividing the bed up into 16, 24, or 36 sections depending on the bed size. It will then probe the center of each of the points and store the height of that position in regards to the known zero height which is usually the center height for ease of reference.

Then during printing it will actually raise or lower the print height the needed height to compensate for the plus or minus in bed height for that zone of the bed the head is currently in. This means for one layer there will be many micro adjustments in Z height as the print head moves through the various mapped zones of the bed.

This leveling scheme only works with true 32Bit processors such as what smoothieboards have and I believe the duet has as well. It requires to much math and fast calculations for a RAMPS or similar board to pull off.

Added progress updates.
