Your videos are guiding me on my DFU upgrade to my BF20L. Thanks. Have you somehow covered the square hole you cut for the Y axis DFU? I did the same on my base but I have no idea how to cover so the chips wont fall in. Again, thanks.
Thanks for reminding me. Hadn't thought about that in months. I haven't got that far in the reassembly yet, but I'm kicking around some ideas and open to suggestions if anyone wants to chime in. To minimize the opening, I'll fill-in or otherwise repair the section of the hole that was cut too big. Brazing in a filler plate might be preferred? But I don't currently have the tools for that. A 3d printed floor/form below the surface, and then filled up with J-B Weld and filed smooth comes to mind. Could drill and tap the sides of the hole to add pieces of small threaded rod to reinforce the epoxy repair, though I doubt I'll go through the effort. Since the repair is not structural, and essentially just a dust cover, the epoxy should suffice. If not, it's easy enough to remove and try again. Actually a 5-6mm thick, solid 3D printed filler piece, epoxied in place would do the job too. Though not as robust. Something simple like the rubber cover at the back of the Y-axis could be fitted, though that doesn't really appeal to me. I was considering 3D printing a cover with telescoping slats, like are found on some car shifters to keep out dust and debris, but small chips would likely slip through the gaps between the slats. Or, perhaps a vinyl sheet on a spring loaded roller like a window shade. An accordion like on the Z axis, probably won't work well since chips will collect in the valleys. Once the repair is made to the oversized hole, a simple articulating 3D printed cover attached to the saddle may be all it needs.
I believe there are enough gap between the top of the base and bottom of the carriage. You can stick an aluminum tape there. I'll try it this night. Best, Suat
I haven't done anything else with the gibs yet. I'm still trying to make time to build the electronics enclosure for the mill. The 3D printed gib seems robust enough to mill the clearance slots in the original saddle, in which case I won't need new gibs. I'll use the original gibs with the original saddle.
@@joat_mon thanks for the reply. I ended up using the broken gib as they fit nicely together and seems to be working ok. I ordered two replacements but will require a ton of work to get it to size.
Just found your channel and Subscribed. Very nice machine.
love the 3d printed gib idea!
It's still in there... Any port in a storm.
I'm developing a whole new respect for plastics.
I think it will be good enough to get that saddle milled.
Nylon would have been a good material for the gib.
Thanks for the tip.

We’re you able to fix the gibs? I got replacement ones but they are still too big and need to be ground down somehow
