Well I got some Thomson fully supported rails for the Y axis from ebay and some hiwin linear bearings from automationoverstock for the Z rails. Should be here in a few weeks.
I got a quote from Kerk for the lead screws and nuts. Their 60" TFE treated screw with antibacklash nut is $341. Roton is $120 (no coating and no backlash nut). McMaster Carr is $175 with wear compensating nut. |
