Ok First off, using the CREATBOT DX3 is fun! At first, I thought I would just make a few 'fun' things then lose interest. As it happens, I'm finding all kinds of things I can design (Using RSAllied Designspark) useful items to repair or replace things around the home and garden. Example: A replacement knob for the clock setter on our oven (could not find a replacement anywhere on the internet), a bracket that clamps onto my lawn mower to hold the throttle and drive cables in place, clamps to relieve stress on outdoor lighting cables strung over our patio, new hubs to hold the plastic reels on the back of the CREATBOT, and more.
The bad stuff:
1)The platform is cantilevered off two linear bearings that have a lot of play. So adjusting the platform for consistent gap from the extruder nozzle is a constant chore, as the platform position can pitch and roll due to sloppy bearings and less than rigid construction.
2) When (not if) the filament breaks, retrieving the broken pieces out of the feed tubes is difficult. It looks like the feed tubes are terminated by 'quick release' connectors, but either they're not or I'm just not strong enough to detach the tube from the connector. So I have to unscrew the connectors from the terminating blocks, fish out the broken pieces of filament, reassemble, and yes, re-align the platform. I'm getting faster at it, but still.
1) Replace the linear bearings with larger, higher quality bearings that don't have such sloppy fit.
2) improve the rigidity and squareness of the platform (preferred) and/or provide a means of adjusting the angle between the platform and the linear bearings.
3) move the linear bearings to the sides of the platform so the platform is not cantilevered.
Although the CREATBOT DX3 could use some improvements, for what it is and for what I paid for it, it was well worth the investment.
Thank you, CREATBOT inventors and engineers!
