Nearly 3 years of many many revision, If I had to guess its over 300. 4kgs of prototypes printed in PLA.
Now the design has finally reached a point where I feel its about time to release everything for the design. The design drawings will come later as there have been revision on all of them, so i have to make up all new ones.
Here’s the printer i’ve named Castle. The max build height used to be 400, but figured aint not kill like overkill lol
So here it is breaking 750mm travel in the Z, the legs are 1.5 inch extrusion plus 3 ball screws and 3 linear rails. The printer should be call Overkill but oh well.
Here’s the Step file https://drive.google.com/open?id=1zSAQa38hQCTQZ8dPLEQ3YWw8xYlE3a9Z
If anyone notices anything wrong with the design i’d like to know. Thanks
I built a D-Bot, similar frame as yours. I have about 430mm of build height, and I need to do something to make the frame more sturdy. Some diagonal braces at the corners would probably help a lot.
is the x axis is a unsupported linear slide? that will ring a lot… you need to reinforce it with either a plate or a 2020 box section
it has 5 m3 screws on either side, Machining a full length part adds to its cost. as a very large fixture is needed.
Ill run the assembly through FEA in F360 to see whats what.
@Jordan_Bourns the x axis acts like a beam on which the x carraige is applying force in the y direction when the gantry changes direction. unlike a prusa style printer in which the gantry has only side to side force and can get away with 8mm rods. i made a similar mistake on my corexy by having 8mm rods in the long direction . it rings like crazy and i had to turn down the acceleration and speed to get decent results. but again as you are using a bowden it might just work fine
