what thickness is the bed? Did you machine it? I made a 400*400 and got a 6mm sheet of aluminum as bed but it wasn't perfect flat. I am thinking to make it from glass. I also notice you changed the Z axis Delrin wheel brackets with aluminum and add a second. Did you had issues with Z axis from weight and made these modifications? Should i add another?

 

very nice. what about the z axis motors? are they nema 17?

 

Hi there, I want to build a D-bot also with an increased size of 30*30*50, could you help me out pointing me what do I have to change to achieve this?

 

Mostly the aluminium extrusions I need to buy for 30*30*50 and the leadscrew? Besides that and belts, I am guessing everything else stays pretty much the same?

 

Hi,
Your machine looks fantastic !
so all extrusions are 500mm in length ? or do I add 200mm and 100mm to the v-slot rail sizes in the D-Bot build guide ?

 

Great design. Fantastic. Let us know the update. I just start print the parts to buld 300x300 .. without any background in electronics. I am an architect designer. I need help
I based in dubai. Owning printing center.
I need more printers .. i think the dbot will help that..
Reagrds

 

Thank you so much...
I just near to finish the printing the parts using PETG by prusa. I dont know if there is any new update stl.. i juat download it from thingverse. Also i am waiting the v-slot. And the mechanical parts.

To be 300x300. Printer. And i tried to find a heat bed 300x300 i confused to find the best. Usually to use it for PLA in future .
Any assembling video ?
Regards

 

Thanks for the video. I will start to assemble it. Next week. I need to know about the auto leveling "parts to be print' and which method shall i use? And firmware update? "

Hey Troy, super nice build. I'm looking to build one myself just like yours, 400x400x600. Can you point me in the right direction? First, where did you source your aluminum extrusions? Here in openbuilds? Also, can you share more details and pics about the mods you did to your Z axis? I'm concerned that with such a large and heavy bed it will flex. Thank you and super nice work!

Also, HD pics of your prints would be cool, to see what kind of surface finish you get. Thank you a lot!

 

Thanks for answering! That looks complicated! do you think that I could do with two leadscrews, one on each side of the bed, in the middle? If the bed has wheels on all four corners it should be quiet stable right?

 

Hi, I see that you have used metal brackets for the z wheel carriage, what brackets are these?

 

Cool, thanks for replying. That looks like a solid setup, haven't seen that before. Any thoughts on that setup vs your old one with 3 lead screws and wheels running on the frame? Do you feel it's a worthwhile upgrade?

 

That's a very interesting way of doing it. I'll have to keep it in mind!

 

Hey, I'm trying to put together a d-bot. Just started my research. Say I wanted to build a duplicate of yours. would you be willing to share the bom?

 

alright, what makes up your z-bed?

I can see the c-beam, etc. But I mean, what lead screws and pulley's do you have going on down there, and what size belt? Also what size and pitch lead screws? you said its a nema 23 i think, what stepper driver are you using on it? how tall are your c-beam's? Is that a KFL8 bearing mounted under the c-beam?

Any measurements you can share would be greatly appreciated.

Also can you share your stl files for the z-base thing? and the mn12 rail gantry?

Are you using 20 tooth sized pulley's for the x-y axis?

Thanks a lot for the info.
