Quotethe_digital_dentist Do these "unbalanced forces" cause problems? With careful positioning of pulleys, a single-level corexy mechanism could be made free of "unbalanced forces", I think. OTOH< if you want to try to come up with a new belt layout... Depends on what motion system you use, but for rods and extrusion rails they can cause problems. Not so much with linear rails due to the toby Heracles421 - General New Machines Topics
Quoteo_lampe Now it seems right, but the kinematic is a mix of H-Bot and CoreXY. dX = dA ( red belt ) dY = -dA + dB ( blue ) I don't know if it's worth adding extra length to the blue belt and get more stretch/ringing there, just to fight extruder tilt. ( which is neglectible when using linear rails and carriers) edit: I just saw that both belts are equal length, so forget my above comment. Iby Heracles421 - General New Machines Topics
Ok, new design... Any thoughts?by Heracles421 - General New Machines Topics
Woops, I screwed up there, hehe. I guess I'd need to have the belt fixed on a single point, thanks for noticing Hmm, after giving it a second look I now notice this is totally flawed... Back to the drawing boardby Heracles421 - General New Machines Topics
So, I was derping around looking at Core XY machines to build (Specifically HyperCube EVO), and I started to think "Hey, crossing belt CoreXY is nice and all, but the belts getting misaligned is a bit of a pain". Then I also looked at the HEVO's approach but noticed that not crossing the belts induces a torque onto the extruder assembly. So, I thought, "Hell, why not try to design a new system?".by Heracles421 - General New Machines Topics
So, I designed a mount for the Tevo Tarantula's stock hotend. You can find it here: Video of the unit working: I also ran a lot of tests yesterday and found out it's pretty damn precise. Pictures attached.by Heracles421 - General
