Viesturs, It might add some positioning error, but I am thinking of something on the order of a couple hundredths of an inch or less. The application is an ultrasonic knife cutting table, so with the flex of the blade I can certainly tolerate a couple hundredths of an inch error on one side of the gantry. The motors and amplifiers are identical, so performance should be very close to identical as well.
I do not see two home switches as viable, it is a prox switch, so precisely aligning the field effect of two such switches would be a nightmare, not to mention how easily one could get knocked out of alignment. Thanks, Eric Correct me, if I am wrong, but AFAIK adding deadband will added also in the positioning precision by definition, I seriously doubt that it is acceptable. Any reason not to add another homeswitch, so that each of those joints has one and treat it as a normal gantry machine? ------------------------------------------------------------------------------ Dive into the World of Parallel Programming!
