Acceleration required will vary from machine to machine. Variations in design, motors, machine setup, parts used, driver type, with current setting and operating voltage etc all impact the performance of the system.by annodomini2 - General
The problems are mass, inertia and friction. The elements of the Cartesian bot have all 3; 1. When starting/speeding up, the mass of the system need to be accelerated to the desired speed and at the same time, the friction overcome, to do this in one step requires enough force, or in the case of the stepper motor, torque, plus the interface between the stepper motor (gearing, belt connections eby annodomini2 - General
You will have a finer resolution, but slower operation as twice as many steps are needed to travel the same distance.by annodomini2 - General
The Pololu (as used by RAMPS) and the EasyDriver have a different pin layout, the easy driver board wouldn't fit a RAMPS mounting pointby annodomini2 - RAMPS Electronics
The problem with the printing solution is the gate width of the devices, you can see they are imaging the device with photography and you can see the connections. That device is only 20bits of memory! Most modern electronics need to be imaged with an Electron microscope. In conventional electronic production they are heading towards 20nm gate width. The problem is and will always be print resby annodomini2 - General
Hope you had fun, sorry I couldn't make it (wife is heavily pregnant! ) Will probably not be able to make one till the new year, due to commitments.by annodomini2 - West of England RUG
Very close to me, I need to check my availability, but should hopefully be there.by annodomini2 - West of England RUG
The processor does (STM32F103), but I don't know if the board exposes them.by annodomini2 - Next Wave Electronics Working Group
There is also a scale issue, pellets tend to have a minimum size, this affects how small the feed unit and screw can be, given the current size and power of the machine, an extrusion unit based on screw principles may be too big for a typical Mendel design. Would love to see one though if it is feasible.by annodomini2 - General

The SD card operation is still very prototypish, it's not impossible, just not very well developed. Sanguilolu No the board doesn't directly support it, unsure if you can expand to it.by annodomini2 - United Kingdom RepRap User Group
I would suggest sanguilolu or RAMPS, basically all the main components are on Daughter boards so if something breaks, you only have to replace the broken component rather than the whole board (especially if you don't have a surface mount repair capability) Gen6 will be more electrical noise tolerant due to the single board.by annodomini2 - United Kingdom RepRap User Group

Pub, let everyone get to know each other first.by annodomini2 - West of England RUG
Single clock integer multiply (not in the AVR!) is quite common on newer processors. Single clock integer divide is quite hard to do in silicon, though not impossible. I am uncertain if they have cracked this with floating point. Division is generally slower than multiplication in most micro's, but it does depend on the implementation. One suggestion is to try and leave the divide operation tby annodomini2 - Firmware - experimental, borrowed, and future
