[Emc-users] Planning phase for new machine, need decision support

As you might know (according to recent mail activity) I'm going to build a new machine. My plan is to use a mesa card setup and the machine will support 5 axis, but I will start with three... ...I think. This is where my need of decision support comes in. I have always used servo's even on smallest

[Emc-users] Controlling a tool changer

Guys, I am in the planning phase of making a small machining center (i haven't found one I'm pleased with...) and I need a tool changer. My idea at the moment which still is in a sketching phase, is to make a Tormach style changer; http://www.tormach.com/upgrades_tts_atc.html I'm going the Mesa ro

Guys, I know a Finnish guy (who else...) called Juho who managed to replace the engine ECU for a Volkswagen TDI engine with an Arduino board. He's even running a car with the Arduino successfully. This would be a great tool for everyone who converts old cars to better and stronger engines, such as
