You can try slice again then print.<br \/> \u200b<br \/> 5) Make sure the height of both left and right side of X gantry is same when you measure from the leg.<\/p>\n<p>There may be causing by some other issue as well, you\u2019ll need to find the possibility and tackle it one by one. Maybe can search on the Facebook group or youtube, see how other user solving similar issue. Sometime it could be due t some issue that we don\u2019t even thought off.<\/p>\n<p>We once got a Ender 3 having similar issue, took us quite some time to find and tackle the possibly issue. End up we notice it could be\u00a0due to the X motor plate not angled properly in 90 degree. So we try add a washer to one side of the brass nut to compensate the angle, printed a 1mm thicker Z motor mount to replace the original, it can be found in thingiverse.com.<\/p>\n<p>Hope the information above can help.<br \/> Let share and learn together by letting us know how you solve the similar issue in the comments.<\/p>\n<p>[\/et_pb_text][\/et_pb_column][\/et_pb_row][\/et_pb_section]<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Z Backlash could caused by these few problem: 1) Z axis POM bearing\/wheels too loose or too tight.
