Well the male/female socket looked pretty good, but couldn't be put together, the female end broke when I tried to put them together.

I think I found the issue, I forgot to calibrate the X/Y axis, so it was elongated. I ran through the calibration process on the galvo and aligned everything MUCH better. It was computer generated before based on everything being symmetric.
I may have found another issue, either my power supply is bad or the supply they shipped is on the verge of being powerful enough. It is a 2.7amp supply @ 24v, and maybe the BBB wireless is using a bit more power than the BBB (non-wireless), but I seem to crash periodically. Thankfully never during a print, but I'm going to see about upgrading my power supply.

Today my supply is working better. I'm working on making a few gifts for my daughter for the holidays. She loves sharks so I picked out a few things from thingiverse and am trying to print them. So far I did a shark. I'm not using supports, so I ran into an issue that to secure the print to the build plate I run the laser at 8x time for the first 8 layers. That's a bit too conservative and I think I'm going to start trying to cut that down. I have the shark comb in my UV box, when it comes out I'll take a picture of it. You'll be able to see the over exposure from the first few layers. I'll also keep notes posted for each print. Some of them I used supports and some I did not. I didn't like the supports I was seeing in slic3r and that is what I'm currently using, for better or worse.

I put a new power supply on my printer and the Z axis runs very differently, the good news however is that I can just unplug the power cord from the outlet and not also the printer, then plug into the outlet, then into the printer as my old one did. I wonder if the zaxis will end up working differently for different power supplies. Could also be the reason I was having issues previously. May likely do some improvement on the x-axis in the future as well.
Note: the calibration file has tuning values for the zaxis, I'll tweak them this evening after this print completes. Hopefully if I can reinvent the zaxis code it won't vary from machine to machine or power supply to power supply, or whatever the issue might be that I'm having.Last edited by doobie; 12-22-2016 at 03:40 PM.

Most everything without supports prints nicely, anything with supports fails. I either need to figure out supports in slic3r or try a new slicing tool.

meshmixer (free) will add supports to an STL file, independently of the slicer

Thanks I used that and was able to print the flying shark finally. I was also reading other forums that recommended mesh mixer. The other forums also used Cura, but I liked slic3r because it could run on the BBB.
I have been having issues with the wireless BBB black and am thinking of switching back to the wired version.
I passed the flying shark picture online unfortunately I'm not a photographer so my pictures don't do justice to the prints. They aren't perfect but I think pretty good.

Things seem to work pretty nicely on the prints I made for my daughter for the holidays. I am seeing some issues where it appears a print after a period breaks off the build plate and sticks to the VAT. I've seen this before many times, but I've never found a solution. I've seen it in cavities without air relief (it likely makes a vacuum) as well as prints that are solid as they print and the newly printed layers are larger than the top layer on the VAT. I've tried a number of things to fix this, but so far I haven't found a robust solution.
I started using meshmixer to add supports instead of using slic3r; which I have not had success with supports yet. I've found it does good for the raft/brim layers, but other than that it didn't do a good job for supports.
