Another way to mechanically connect the ends of any gantry. Fit a rack along each side. Mount a vertical shaft on each end with a gear at the bottom to engage the racks. At the top ends of the shafts, mount right angle gearboxes with a cross shaft connecting them.
If the underside of the table is clear, with part of the gantry running below it, then there are arrangements of cables and pulleys that make it always stay square. The original Thermwood control system never had a problem with the gantry trying to get crooked. Perhaps digging into its system could yield some useful information? Is this retrofit a complete one, motors, drives and all? Or is it leaving the motors and drives and replacing the computer? Just wondering if the never-fail keep it square system had nothing to do with the controlling system but was built into the drive system? If you've replaced *everything* electronic and electrical on the machine, then you've removed the 'magic' system that kept the gantry square. ------------------------------------------------------------------------------ Try New Relic Now & We'll Send You this Cool Shirt New Relic is the only SaaS-based application performance monitoring service that delivers powerful full stack analytics.
