3D Cement Printer
I am prototyping a cement printer. So far, I have the first version. It’s 1/3 of full scale and the major
parts are done. I have Arduino and RAMPS for the brain and Toshiba James Newton Massmind 4 Amp
drivers. (Software- Pronterface, Firmfare- Sprinter.)
But I am having some trouble, and would appreciate assistance. Thanks in advance!
1) How can I disconnect the temperature function completely? I don’t need it for a cement
extrusion. For now I am using a solder iron to heat a thermistor to start a printing. I can certainly
use a resistor for that purpose, but I am thinking of getting rid of RAMPS. Looks like I only need
to use an Arduino 2560 board because I just need direction and step signals.
2) Question about scaling and travel distance- for now I have 4m (12 ft) for X, and in the future, it’s
going to be 12m (36 ft) X and 20m (60 ft) Y. It looks like Sprinter does not like these digits and
won’t let me set up distances this long. Where and how can I do this?
3) Is there anybody willing to help to draw a simple rectangle in any CAD and make STL files? I have
to do the first printing soon, and have so many things to do regarding the mechanical parts,
welding, wiring, etc. and not enough time to study CAD. I need 2 simple boxes like this, with one
box inside the other, space between the two walls (no mesh between the walls). Eventually, on
a real house, there’s going to be insulation between the 2 walls.
