Stress testing the MRR ESPA

To make sure the MRR ESPA works stably, I have been using it to print some stuff. Some of them were fan covers (40mm and 80mm) and bases for mounting the MRR ESPA board and the more advanced MRR ESPE. But some were more for fun. Like these.




All of them were printed on my modified Ender-3, which has a clone Titan Aero direct drive and is controlled by the MRR ESPA. I haven't done much tweaking; it is still using an old profile meant for use with linear advance (which is not enabled on the MRR ESPA). With coasting and such, I should get better results, but my purpose now is not quality, but more to test stability. All in, the MRR ESPA has probably completed several hundred hours of printing.
