So, the #fuseboxCoreXY project is coming along nicely. I’m really happy that my designs have come together well. I should hopefully have it moving by the middle if next month depending on the post. I’ve now totally removed all cable tied bearings so there will be no slop from them. The Y Axis mounts needed a slight tweak to guide the belts a little better, they’re on the printer now. I was really surprised at the fact the didn’t break due to the orientation they have to be printed in, with the stress going along the layers opposed to against. I’m probably going to replace the Y rail mounts with metal ones as the plastic ones can’t take much stress and I’ve snapped the back off a few. With the metal ones, it’ll allow me to slide the rails into place, which will make removing the carriage for maintenance a lot easier. Still, I’m happy with the progress…
Looks good, yours is 2020 right?
@Jonathan_Lussier yup, based off the Culain design. I’ve pretty much junked the Y carriage ends, the extruder carriage and hacked the Z mounts to bits to add in push fit linear bearings to kill any flex coming from the cable ties. This isn’t my quote but it’s something that I totally agree with ‘cable ties are the duct tape of the 3D Printing world’
Ha-ha nice, I would reverse one of the diagonal supports and put another in the base to stop racking. Also when I build mine I will use the misumi corner pieces (metal) that come with their standard AEX units.
Tbh, it’s pretty damn solid as it is, I was quite surprised on the stiffness considering the printed parts.
