Last couple of weeks I’ve been working hard in updating my delta 3d printer. Here’s an update:
- first of all: I changed the frame. From a handbuild one to a cnc-routered(?) one (see pictures in another post)
- I changed my heated bed suspension from stationary to a spring loaded one with bronze knobs for a adjustment which a made myself on a metal lathe (I did this for the first time this week, exciting machine a lathe is ;))
- And last but not least: My magnets to hold my diagonal rods, weren’t strong enough. So I simply put an extra elastic band between my end effector and my carriages and that seems to do the trick (I can already get to 150mm/s!)
For now; some new pictures
Nice work! I was just pondering the best way to build in a spring-loaded build plate as a mod for my Kossel mini. How much preload force do you think you have there? I’m also planning to refit for magnetic joints, or at least spherical ones. Is the copper shield around the nozzle intended to prevent heat loss to the build fan?
@Dominic_Amae thanks! I don’t know how much force the springs are exactly, but I took them from an old heatsink for a CPU. The middle of the bed is hard to push down by hand. Only on top of the springs them self I can push my bed down. Hope this helps you… The copper shield is indeed for protecting the hotend. This way I can fit my fan everywhere I want without adding a fan shroud. And for the magnetic joints, be aware your magnets should be REALLY strong. Mine seemed strong but kept disconnecting when printing big/fast. That’s why I had to use the elastics.
