First of all, let me say this: I really expected this section of the forums to have a lot more posts than what it does. Is this a new subforum? Anyways, I purchased a box of 3D printer parts that I found on Facebook Marketplace. It looked to be several of the cheap "Flsun" Kossel Delta 3D Printer kits and an Anet A8 kit, but I figured for the price of $50, if only half of the steppers work and one or two of the boards work, it would be money well spent and I could use the parts on some of my other printers. So, I tested a lot of the components and everything seemed to work. I decided to go ahead and put together one of the Kossel Delta printers. This is my first delta printer, but I do own several Anet A8 / i3 Clones, a MakerBot 3, and a Flashforge 3D so I am not completely new to 3D printing. Long story short, I ended up assembling one. It works great, but I can not get it to print on the build plate. I assembled another one, same issue. Only prints just above the build plate. Assembled the 3rd kit and the same issue. Given that all of them are having the same issue, I figured it must be a setting that I've overlooked. I've updated the firmware to the newest version of Marlin on one. The other two have the original firmware. I have adjusted the Z height offset in the firmware configuration files. I've manually leveled the bed and I've tried using the auto leveling feature that these units have. I've pretty much spent all weekend working on these things and I am wondering if anyone here has any suggestions or a setting I may have overlooked. This is my first experience with the delta style printers and it has already been a little bit of a learning experience. Looking forward to see if anyone has any ideas or suggestions. Thanks!
