Lead-screws upgrade kit

Leadscrews Plate and Bracket Upgrade for Makerfarm Pursa Printer To undertake this upgrade, procure the following components: 2pcs of 5x8mm couplers 2pcs of lead-screw rods with the following specifications: length = 300mm, diameter = 8mm, pitch = 2mm, starts = 4 (these parameters align with my own specific requirements) 2pcs of compatible brass nuts The plate alone will not suffice due to a discrepancy in motor and bracket centerlines, necessitating a slight forward adjustment to synchronize them. To facilitate this modification, review and adjust the configuration.h file as outlined below: define DEFAULT_AXIS_STEPS_PER_UNIT {80,80,400,841} // calculate based on (revolution/microsteps)/(pitch*starts) Refer to http://www.protoparadigm.com/news-updates/accuracy-vs-precision-and-threaded-rod-vs-leadscrews-in-3d-printers/ for a thorough understanding of the reasoning behind this upgrade. Feel free to request further guidance or upload a picture of your printing efforts along with any feedback.
