I installed the belts for X-Y axis'. I've noticed that you can skew the gantry out of alignment if you over tighten the Y belts.
I started to route some wiring and realized that it would be better to move the Z Axis lift motor assembly to the right side of the cabinet. In this way the motor wiring will easily reach into the electronics equipment bay whereas before I would've had to add extensions.
As an aside, my Laser Tube's due for delivery tomorrow. I bought it from VIP Lasers for $600 + $52 shipping (FedEx) from Las Vegas. That was a great deal for a RECI 80 watt tube, however, I noticed that VIP relisted the same item on EBAY for $685 + $52 fedex.....Now it's not so good anymore, IMO. At that price you can get it from any number of other internet sales companies. LightObject's RECI 80 watt Tube is $585+135 shipping, $720. Of course there's an advantage to being shipped from Vegas vs. China which is where (I believe) LO orders are fulfilled.
