A good maintenance routine is available via https://support.xtool.com/article/1134?from=xTool+P2&url=/product/4, but it fails to detail the type of lubricant that should be used on the X-axis guide rails or the Z-axis guide rail, also it would help if the timescale for the maintenance was detailed e.g. after 100 hours of running and each100 hours therafter.
