Hi, i am building a corexy printer and i want to ask if it is ok to add pulleys to the corexy system. I added the nr1 and nr2 pulleys to gain some space on the x axis. Is that ok? What can go bad with this? The pulleys are one on top of eachother and normally the belt should go from number3 to the idler, i added 1 and 2..

The most important thing, regardless of the number of pulleys, is to position all the working segments of the belts parallel to their respective guide rails. Working segments are all those that vary in length as the carriage moves. You can do whatever you want with the other segments.]]> the_digital_dentist CoreXY Machines Tue, 24 Jan 2023 09:58:47 -0500 https://reprap.org/forum/read.php?397,891785,891788#msg-891788 https://reprap.org/forum/read.php?397,891785,891788#msg-891788
If you mean a beltpath like on the Ender-7 (see attachment) I can confirm after one year of heavy usage it works fine.]]> reaprap CoreXY Machines Tue, 24 Jan 2023 07:30:37 -0500 https://reprap.org/forum/read.php?397,891785,891785#msg-891785 https://reprap.org/forum/read.php?397,891785,891785#msg-891785 RCalin CoreXY Machines Tue, 24 Jan 2023 03:51:11 -0500
