I am building a 5 axis plasma w/ bellows to cover the linear ways/belts of course!
I am using 800W JVL MAC800 intergrated servos on XY and I am aiming for 3000ipm rapids.
thanks again!
Hi King, or is it Kong? I do have photos I can post soon, we've now got a 5:1 belt reduction for SBLH and have delivered a few pre-production units. We are rolling out the ServoBelt Heavy configurations soon. It broke it's life test rig, which is being rebuilt, but before that it had attained 5 million cycles A-B-A at 300 lb accel/decel forces and looks like it will do a lot more.
I'll get to that, but want to show the laser flat bed cutting gantry we just did using ServoBelt Medium and Renishaw magnetic linear encoders (1um). I'm not at my computer, but will try. It's basically a 4'x4' with 2 meter/sec and 1g capability.
With the linear encoder feedback as the only fb, it is a phenomenally stiff and quiet servo loop. This gantry is targeting routing, waterjet and laser systems.
