Hi everyone,

Well, the Holy Rack of Marchant-Dice finally arrived and got fitted today so that is the mechanical side pretty much complete. I'll take pics tomorrow, and get them posted.

Now, a question. I'm using a timing belt (15mm) to drive the X axis on the rack. Most belt systems I've seen use a small idler but I have just tensioned the belt by making the stepper mount adjustable. Should I put an idler in there? The only reason other than tension I can see for one is to wrap the belt around the pulleys more, is that the case?

On to the limit switches next. I'm using some microswitches from DIY-CNC (roller type) but may upgrade to optical switches later on depending how they perform.

Take care all and have a good weekend!
