About Vlad Tepes

Vlad Tepes is the historic figure sitting behind what is known as "Count Dracula". The public image about him couldnt be more wrong than that. This short introduction is meant to do a little justice to a man who himself knew no compromise about justice.

On short, he lived during very dark times. As time habits were, he was raised at ottoman's court as an "lever" of his father behavior on the throne, e.g. if his father would misbehave then he would of been executed. He came to throne in a context where there was no law, but corruption and criminality were ruling instead. Most of sources blame him for cruelty and executing his enemies, things which arent quite accurate either. He intended to eradicate criminality, so he executed the criminals, at start mostly by sword, like he saw in childhood, but it seemed to be a never-ending job. The choice to impale the criminals instead was meant to leave them there for public awareness, and probably came from the suggestion of one of his aids. The method proved extremely effective and in short time after, criminality was in fact eradicated. He took measures to strengthen the economy and help the working peoples. Among these, he imposed restrictions for traders coming with products from other places (like customs taxes do nowadays). For this he became hated and the outside traders actively plotted to kill him for years. If there is anything that can be said about his rule, is that he made no compromise, in justice or anything else. And who lived long enough knows that making no compromise is not a little thing. Sadly, this behavior in the end sealed its fate. As a ruler he was loved by the ordinary working peoples which gathered to form army to his aid more than once. His grave is not known - if would be then i suppose if would of researched genetics for ways to clone the guy, instead of this.

Legend says, one old man made a fountain aside a road for travelers to have fresh water. The recipient used for drinking was supposedly made of gold. One day the man goes to the fountain and see the recipient is missing. He then said "Vlad is no longer on his throne".

Little Vlad Tepes knew that a few centuries later, the world would remember him as a guy obsessed with sucking blood out of sexy virgins ... (yummmm to that btw).

This is just one of the many general misconceptions i can see from where i am standing, and this also should remind us that general judgments cant be passed about a person, unless we know hard facts, or we have been in that person's place for long enough to understand where he comes from. This is obviously not related to reprap, but it is a good example of what kind of misconceptions we fall prey to. If this was *that* far away from reality, then simply who knows what else we have got wrong.



Initial point of view and considerations

- Vertical axis setup is considered, with the intent of bringing something extra, in terms of features, versatility etc. In this context having a dual axis for a second toolhead is a direction to explore. Mostly because its so easy to do, e.g. rods will be in a square config, 2 at each side of the Z drive. Having a separate axis could let us have a second toolhead without increasing the weight of the first. There are alot of considrents to it, e.g. there is no current electronics and firmware which could eventually deal with a secondary independent axis. How the second axis could be justified is a question mark, but i am sure it can be put at some use in the end.

- For a number of reasons, i am obsessed with rigidity and the 8mm rods are not inspiring me confidence for the job, so 12mm is the choice, smooth rods + linear bearings. With bigger components and second axis, i think a bigger frame would be in order, at least makes more sense in the context. It probably should use 12mm for frame bars and vertices aswell, but for now will pass on that as it feels kinda much.

- In the end this is pretty much for myself and not primarily for the Vert-x contest. In advance apologies if this doesnt make it in time to meet the deadline.


Initial frame changes

1) Rigidity obsession pack: frame "patching" with rod clamps, from place to place, in different positions. For 8mm frame.

2) Accommodation for 12 mm Z smooth rod.
