Automated Belt Tensioner XY-core tronxy & supervision with STEP files

May 2021 After the information from https://www.thingiverse.com/toto-42 I recognized that this Automated Belt Tensioner is made for X5S-PRO with a higher belt guide. You can see it at the difference of the Plates of the XY-Guides. For the X5S you can use the https://www.thingiverse.com/thing:4859990 For the additional parts it is also useful to have a look to his summary. (Spring; Roll...) Feb 13 2021 I just added for the main parts the step files. May that helps for remakes. Jan 27 2021 Like many of us it is not easy to recognize a sufficient belt tension for a proper 3D print. Therefore I build this automated belt tension with supervision during print. Normally the tension of the roll will move about 5mm when direction of the printer head is changed. When movement increase, the tension will loose or there is some additional friction in the XY-core system. You can recognize it and avoid problems for the next prints. You can also calculate the accuracy of the print by calculation referred to the movement. I am about 17cm away from the next fixation. 5mm movement is an accuracy of about 0,14mm in the belt tension. The tension of the spring can be adjusted by the distance of the holder "Halter". I use special bearings I found in my maker box :-) for the roll (8mm height) You can also use 4 * F623ZZ with flange and M3 screw as axis. https://smile.amazon.de/10-St%C3%BCck-Edelstahl-Kugellager-Flansch-Flanschdose-default/dp/B07BR5Y622/ref=sr_1_5?_encoding=UTF8&adgrpid=71246206455&dchild=1&gclid=EAIaIQobChMIzJzDyYmX8AIVgbh3Ch2oigM9EAAYASAAEgLhk_D_BwE&hvadid=391629484049&hvdev=c&hvlocphy=1004363&hvnetw=s&hvqmt=e&hvrand=912673845431555014&hvtargid=kwd-299607181859&hydadcr=29223_1989449&keywords=f623zz&qid=1619274005&sr=8-5 Parts used: M3 + M4 screws different length M3 + M4 nuts M3 drill Spring from maker box 2 M4 Boat nuts (T-nut drop in) with screw. The screws in the "sockel" should be fixed for the stability of the arms "Halter". You need to play a little bit with the fixation of the spring not to touch the belts with the "Halter". I made it diagonal. Have fun with it :-))
