"The problem is not just to change the bed size.. but to make it work flawlessly.
i can only recommend something that i have designed, checked and made sure it will work (300mm bed).
before it published I spent more than a month on software simulating, another month of improving and again simulating.
that even before it was built - all to make sure it will work perfectly (balance, stress process and so on).
a few comments below, you will find an excellent solution for bigger beds that another member like me and you came with.
adding another Z extrusion can be wise for heavy (400mm+) Z/bed carriages" - BLV

CNC Machined Parts

by Merdoc

Hi Ben,

I just saw your home page about the new metal parts, and want to say Congrats!! That must be huge and you seem elated, they look gorgeous. How are they working out (other than the oval holes)? While on Alibaba I noticed a set of machined parts and decided to purchase them. With the kit from AliExpress and the machined Alibaba parts arriving soon, I was hoping to get your first impressions of them and any feedback you have. Being a CNC machinist in my former life, it is nice to know the critical components can be made from aluminum, where strength and reliability will not be a factor. Is there anything you can see missing or lacking in the parts? How is the alignment of the belts? Any words of wisdom for me putting the BLV together for the first time? I’ve been busy getting all the resources, configurations, and firmware together, steep learning curve coming from a modded Ender 3, but not impossible.
You must be very busy, and amusing me with my questions is low on your priorities, that is why I can’t thank you enough for taking the time to post your brilliant ideas and allowing us to share your great invention. Take care and hope to speak to you soon.

Third Z Axis stepper motor?

by DarkTerritory

Hi Folks

I have my BLV MGN hybrid printer up and running and working fairly well, but I am still having issues with the bed carriage flexing back and forth in the Y plane. I would like to add a third leadscrew to give the bed three-point support which will really lock it in. But (There's always a but) the board I am driving the printer with a (A RAMPS 1.4) only has two stepper motor outputs for the Z axis.

Can I drive two motors off of one driver? Would I do that by increasing the current? Or is there another method I can/should use? Is there a 'powered two-fer' I can install that would increase the signal / power enough to run two steppers from one driver?

The other option would be to install a set of fixed toothed pulleys on the two leadscrews and tie them together with a continuous belt. I could do this if I need to but I would rather use a third stepper if that is an option.

Thanks for any opinions you can offer.

i am working in a toolchanger for this great 3d printer. The first Party are ready, but there is still many work to do.

Is there someone who also like to make a toolchanger for this cube? Maybe we can work together on this project.
If someone is interested in, I can publish what I have at the moment and we can work together
