Hey Everyone, just finished a new printer design, the PRO-G! It was targeted as an outreach tool for STEM Society, and was therefore focused on being easy to use, portable, reliable, and open! I also wanted to get rid of some of the parts I had on hand so some specs aren’t really cutting edge: Print Volume: 150mm cubed Hotend E3D Lite6 w/ 0.4mm Nozzle Extruder: SeeMeCNC EzStruder Bed: Unheated 1/4" MIC6 Print Bed w/ 3-point tram compensation Linear Guides: Openbuilds Vslot profile with Standard and Micro V-wheels Resolution: 6.25um on X and Y; 0.625um on Z Controller: Teensylu 0.8 w/ DRV8825s and ReprapDiscount Smart Controller
very detailed STEP file. it appear you have used this ACME nut plate for Z carriage. this is not suitable for “high precision and repeateability” because you can’t actually eliminate the z backlash.
Have you noticed any nuisance transferred into the print because of this issue?
@Step_Cia , prints have come out decently well; so far I haven’t had any real problems with Z backlash. I think this is mostly due to the high z-pitch of the TR8x8 leadscrew combined with a gravity preload that effectively removes all backlash from the z-axis
