This project is just the beginning for a cheap large format printer. The volume is X=340mm x Y=310 x Z=300.
You would be surprised how sturdy this machine is and yet lightweight.
Printed a rough Marvin in under 4 minutes and a detail 0.1 resolution in 40 minutes using a volcano hot end with 0.6 nozzle
E3D V6 volcano and titan extruder, MKS SBase controller and MKS TFT using smoothieware.
I intend to extend the extension pieces to increase the Z Height and look at other versions of the lack table range now I have a fully working prototype.
Yes I am in the process of writing the instructable. It will be entered into the 3D printing contest so please let people know about it and remember to vote.
1) put on 2 x 1KG rolls of filament on the bed to test stability whilst moving and z Axis movement.
2) put on 1KG roll of filament right at the front of the bed mid print and observed 0.9 mm of movement in the layer.
given the machine could easily move with 2 kg and only 0.9mm of movement was evident the layer when 1kg of weight was added mid print, over the coarse of a large print the incremental weight increase would easily dissipate through the layers with no adverse affect. Please also bear in mind the 1kg was added right at the front edge of the bed giving an uneven weight distribution, (thinking on worse case scenario).
The z axis guide rods operate independently from the Y and X Axis and are using 12mm rod and bearings
Thanks for the question and hopes this helps to answer it.
