A big thanks to Balu for taking the time to go through the OXcalculator in details and catching various aspects, including, yes, a couple of errors with labelling of items. He also pointed out the availability of 300 mm lengths ACME/lead screw. As the need for a box to put your notes, since I have the spreadsheet "locked" beyond the few open fields (yellow boxes).
You would think I would of caught the fact an 8 mm ACME screw would use a 5mm to 8 mm flexible coupler rather than a 5 x 6 ! That's fixed now ...
Thanks Balu
