Sunhokey Improved Glass bed clamp and X-carriage Stability

thingiverse

I have encountered the issue on X-carriage having too much play within our Sunhokey group. I am not alone in experiencing this problem, as evident from numerous accounts of the same issue by other users. After completing my printer assembly and using it for a week, I observed the exact same problem with my own device - the X-carriage was moving excessively, exacerbated by significant backlash. Further investigation revealed that the source of the issue lies within the small linear block/bearing installed on the X-carriage. Therefore, I immediately placed an order for a longer linear block (identical to the one used in the z-axis) from the supplier. I hypothesized that replacing this shorter linear block would minimize or eliminate the vibrations on the X-carriage, thereby enhancing overall stability and print quality. The replacement part arrived within two weeks, and upon installing it into my printer, I drilled eight additional holes into the acrylic carriage to accommodate the new, longer linear block. My initial predictions were confirmed: with the upgraded bearing in place, the play and vibrations associated with the X-carriage completely disappeared, resulting in remarkable improvements in print stability. I made an important modification to the borosilicate glass clamping method during this upgrade process as well. According to specifications provided by the supplier, the print size capability of my Sunhokey printer is supposed to be 200 x 200 x 180 mm. However, I encountered issues due to the size of my borosilicate glass and had to compromise on achievable print sizes, ultimately limiting it to 180 x 180 x 180. A too-large clip for clamping this glass restricted further print expansion. Upon inspection of my device's existing hardware, I identified a more compact terminal lug which would suit the new glass-clamping method much better than before. With an intact crimp side removed and replaced with one similar to that on a heat bed screw - now used like a washer within my design, this adaptation allowed the incorporation of my printer's existing leveling spring in conjunction. This upgrade not only augmented the achievable print size (increased from 180 x 180 x 180 mm up to an impressive 195 x 190 x 180 mm) but also made un-clamping easier as well. As seen through multiple visual demonstrations provided earlier, these findings were conclusive: increased space was indeed allocated within my print bed due to this simple hardware adjustment and the clamping spring remained secure for easy removal when needed. I look forward to further contributions that benefit others using these machines in the future. Cheers, Best regards!
