 * '''Z Limit Switch Shearing:''' Jubilee's Z-axis limit switch is located at the bottom of the carriage. Since the limit switch protrudes close to the tips of most tools, it is susceptible to being damaged by debris (such as a failed 3D print).

-Switching out the default XY motors to [https://lukeslabonline.com/products/ldo-stepper-motor-ldo-42sth48-2504ac LDO-42STH48-2504AC] motors fixes both of the issues below:
+Older versions of Jubilee specified a particular LDO motor ([https://cdn.shopify.com/s/files/1/0239/9287/files/LDO-42STH60-2004MAC_RC_RevB.pdf?v=1585856919 PDF]) for X and Y that was quite noisy and caused the machine to resonate when traveling in X or Y between 25 and 30mm/sec. The current design fixes this issue by specifying a different LDO motor ([https://lukeslabonline.com/products/ldo-stepper-motor-ldo-42sth48-2504ac LDO-42STH48-2504AC]) for X and Y.

 Jubilee isn't perfect. Here's a quick breakdown of some outstanding design issues. For a more detailed overview of issues, see the project's [https://github.com/machineagency/jubilee/issues issue] page.
 * '''Noise:''' Jubilee is noisier than other machines. This is inherent to the size of the machine. There are several adjustments that can be made for [[Noise Reduction]], but nothing that will make the machine dead-silent.
 * '''Low-Frequency Resonance:'''  Jubilee has a peak resonance between 25 and 30 Hz. This means that traveling between 1500mm/min and 1800mm/min will cause the machine to vibrate much more loudly than normal. Applying some of the noise-reduction techniques can reduce the effect of this resonance, but they cannot eliminate it completely.
