After a little over a year (okay almost a year and a half) I have finally got my GUS Simpson finished and working.
[
youtu.be]
Sadly due to a computer crash followed by losing my external hard drive shortly after finishing printing the parts I don't have all the files share the design but hope to inspire further development. I may be able to recover some of the STLs from the friend that did my printing.
This is a modified version of the GUS Simpson, a grounded delta by Nicholas Seward, founder of [
forum.conceptforge.org].
The main difference between this design and the original is the belt drive and all joints are balanced instead of being mounted offset.
I am in the process of adding the kinematics to marlin you can get a copy of my current version from [
github.com] if you are too impatient to wait for it to make it into the official branch
known issues are
Slop between bolts and bearings cause minor problems with accuracy.
The z axis has some odd issues with skewing in the -x and -y directions, primarily -x. I think this is a rounding issue in the firmware but I haven't had time to check it out.
The large pulleys sometimes break free and ruin a print. I'm thinking a bit of thread locker and passably another nut might fix the problem.
You can follow the continued development [
