DSF Build Progress Five

Getting there...

Getting there…

Time for another update. The printer is now mechanically complete. All of the motors, belts and leadscrews are all installed. I may have to adjust the X Axis motor mount eventually as it is poking a little bit too far forward, meaning that the belt wanders a bit.

I have received the Megatronics V2 electronics that I will be using on this machine, which I will try and review at a later date. Now it is just a case of installing the wiring for the motors to the electronics and sorting out the endstops. Once that is done I will see about getting it up and running to check mechanical reliability.

DSF Build Progress Four

Now that payday has been and gone I have been able to order a few more parts for the printer. Currently the steppers have actually turned up and are installed. I had also managed to get the frog for the Y Axis laser cut with the DSF logo etched into it.

IMG_2760At the moment printing on my Huxley are the Z Axis couplers, pulleys for the X and Y motors and the clamps for the Y axis. I have the belt for the X and Y so once the print has finished I can hopefully get the Y axis installed and ready to go. The electronics have been ordered and should be here is 3-4 days, the psu should be with me tomorrow so once the electronics turn up I’ll get it installed and get the printer moving.

Finally got the stainless rod and having installed the Y and Z axis. Printing out the rest of the parts for the printer ready for when I can afford to buy the steppers and electronics.

I have also made a handle for the top to enable ease of carrying.

So the build has begun. I have so far managed to get the basic frame made. I have had to add some extra reinforcement to the frame as it had too much movement in it. I am now only waiting on the 8mm smooth bar so that I can complete the major frame build. After that I will be getting the steppers, but that will have to wait until next payday unfortunately.

Thing of the Moment – Rostock

Thing of the Moment is where I find something of interest to print, either useful or fun!

Think of a 3D printer and you will probably think of it having 3 linear axis’ x (left/right) , y (forward/back) and z (up/down) . When you want to move in one direction you move the axis that way. It’s simple and it works – which is why all the 3D printers I have seen operate in that way. But does it have to be that way? The answer would seem to be – no. Step in Rostock.

Up and Down
Like a conventional printer the Rostock has 3 axis – but that is where the similarities stop. On the Rostock the axis all go up and down. No left or right or forward or back. The axis are placed on the corners of a triangle and the print head is attached by rods connected by linear bearings on each axis. With the rods using universal joints they have a wide range of movement. To make the printer produce a straight line all three axis move at varying rates and varying speeds. To update the saying – a video is worth a thousand words:

At a Price
So why is it that not all printers are made this way? Well reading up it seems that geometry calculations needed to move the head even in a simple line are complicated. However this method does reduce the number of parts the printer is made from – about 200. It should be easier to build as well.

And I thought my Huxley was hypnotic to watch…
