Bed assembly
Here we start with the bed adaptation, The biggest challenge, the biggest point of attention: 4x 8x430mm cast toolplates on a 2020 spring tuned frame to allow a precise correction. I choosed 4 silicone heater mat from Keenovo, 600 W each linked in parallel.
One thing I have learn here, past 600mm, the bed need to be fixed at to bottom, like the Voron structure, a note to a future me.
Frame Construction
Learned from the previous Vulcain prototype, I used 30x60 alumium extrusions with a blind join mounting, giving me a quick and effective squareness.
Everything is then reinforced with hiden corners, small corners, and this time I have added custom aluminium plate to reinforces all corners, and this will be used as mount for the whole harfware
Those added a tremendous stiffness.
Z-System
For this build, since the bed is 28Kg almost; 1605 ballcrew with Nema 23 motor were choose
WobbleX WS16 were indicated here.
On this system, I have used HM12-57 motor mount to simplify the system
As I underestimated the mandatory holding torque of the NEMA, I have then developped a passive brake system to help me with the possible bed falling situation
This system have been already tested with a customer need, the system is simple and effective.
BRS-AWD CNC HD
AWD make sense here since we want to have a good acceleration and relay over the belt lenghts
Here the system is all metal, almost, and fully integrated in the gantry frame section
(This product will be derivated in the same spirit for VC4 and VC 3.1 in a near future)
