Accurate Strong Gantry

[JAZZCNC]

So at the end is just a personal preference. I simply don't like that long belts. In reality my small machine works in a lot of dust and never had any problem with the belts.

Yes Boyan it really does boil down to preference and components used not really so much money. My machine doesn't use belts based on money it's soley down to accurecy and repeatabilty/reliabilty within a budget based on using a stepper system.
Any machine using closed loop or some form of error catching setup Ie Servo's/encoders then I wouldn't use single motor and long belts etc.

Regards belt accuracy etc then to any belt/pulley doubters out there then just see this made with a 1300mm wide router with medium weight gantry.!
