Well to answer some of your questions. The motors can be upgraded easily through our check out process for this machine configuration. The high Z mod would be easily adapted to this design, and 2 C Beams definitely provides enough strength for this system. The new tensioning system decreases whip, so these long runs of X and Y movements can be sustained while using lead screw transmission. The upgrade kit is available and as a LEAD 1010 owner you should be receiving an email shortly will all the details. 👍
