In the next few days I'll be installing a Duet WiFi in my sand table- a 1.9 x 1 m corexy machine.
Here's an old video of it running: https://vimeo.com/290296213
I'm in the process of making it run quietly by running high microstepping ratios and gearing up the motors so they turn slowly even as the mechanism moves fast. I'll be shooting some fresh video of it when I have made the changes (mechanical stuff is done- just waiting for the Duet board).
UMMD, my tall corexy printer, is Duet powered. Here's an old video: https://vimeo.com/235837261

@mrehorstdmd that is a cool sand table! I would love to use a clip or two once its switched over.

This is the Cerberus Gigante Deltabot. 5' x 34" print envelope. I didn't use the expansion board, but I am using Duet2 wifi with external drivers which theoretically 'could' have been connected that way? In any case, it's a cool deltabot project. Currently in operation at Arizona State University in the Grant Street Studios 3D media lab location. I'm the 6'3" shiny headed dude in the photo, for size reference.
First day, delivery!
Or just a big tornado print that was ready when I came back the next morning?

When is TCT exactly? I might set up my SCARA arm again if I have some time to do so.

@oliof yep 24-26 september, but we will be putting the video togethe rover the next week or so.
-
I'll prioritize it for early next week then (-;

@T3P3Tony unfortunately, I lost my old config and the new one does exhibit some problems I solved the first time around, but don't remember how .... but I got a nice homing sequence. See https://youtu.be/cRcnrH5-Lzw and decide whether you can use it or not.

Hello
Hello this is my homemade printer.
I can print 570 mm x 570 mm x 570 mm.
I printed a cat toilet for my cat

@KajRep thanks!

Hi Folks,
This is my polar printer, it's down for a bed bearing upgrade at the moment, but she's definitely running and the duet's working a treat.Working volume is 570mm diameter by 1150mm tall.
Here's some footage of her in action...
The YouTube playlist for the build so far is here:

I'm hoping to come to TCT so will drop by the stall. If you want some better pictures just let me know!
Cheers

I didn't know we had anyone using a polar printer seriously! The Polar kinematics support is probably the least debugged of any. I wrote it without having a printer to test it on. Let me know (after TCT) if you find any issues with it.
PS - it looks like you can do some very tall prints!

If all goes well with this prototype I'm hoping to end up with a farm of these and so far it's been straightforward all things considered.
Let me know (after TCT) if you find any issues with it.
Only thing so far is it doesn't seem to be limiting rotational speed near the centre of the bed but that might be me setting it up wrong. Will be in touch once I've got a little more experience.
PS - it looks like you can do some very tall prints!
Hopefully so, the first cheap bed bearing failed at about 1500 revolutions so the tallest height I've achieved in testing is only 300mm tall. My laser jig tool suggests that she should be good to print to about 1150mm but only a successful test print will confirm it.
I'll be in touch after TCT.
All the best

Some video of The Spice Must Flow sand table:

Is a 1.5 meter tall, 600mm dia bed, delta worthy? I can get some pics. And I won't have hurt feelings if you already have enough large deltas, there are some really cool printers up above in this thread.
-
@Danal Thanks for the offer, I finished off the video for TCT a couple of days ago, and hopefully it's been running on the stand today, and for the next couple of days (I'll see when I go on Thursday). We did have quite a few delta printer videos already! I'll ask @T3P3Tony if we can post it on youtube or somewhere for people to see. Might yet need more videos if we decide to jazz up the website!

Sorry I just saw this post. We are running 4 completely machines with a 900x1200x1500 build volume. Maybe next time.

...The Spice Must Flow...
Looking forward to next year's film? Lynch's effort was entertaining but not a patch on the books and the voice module things were a terrible idea!
