The mission of building a light strong 3d printed drone presented some challenges. Our build is doing well but refinments are always part of a continued development process. One of the areas i have wanted to improve is the blade guard assembly. Currently it is 6 parts glued together then secured to the body and struts. If I could get a larger printing bed this could be a game changer.
So the research was done, the creality corp made a 500 by 500 so we looked at their build, read about the dificancies and incorperated the update into our build.
When the electronics were connected and power applied of course the duel z channel was not configured correctly so I disabled 1 motor for testing and tuning. At this point I realized the Z tower was out of place by 2.60. Rather than try to reconfigure everting My best choice would be to just move the 2 Z poles. Bad mistake but this is a learning process and I'm building without plans as usual just wing'en it.
This is a calculator spreadsheet I found while trying to adjust the extruder. It's very detailed and designed by a math genius so it might be a little overwhelming, I will post my results if i get any
I finally got the machine back on track. Again I have succumbed to failing at trying to control 2 z axix motors using the 2 seperate drivers and allowing auto bed leveling. It wasn't the fact that somehow I burned a driver chip but when I was getting close i kept getting different adjustments. It appeared to be working correctly, I was getting a response that said adjustments were made but all in all it really only adjusts the bed at one location across the x axis. the long run along the y axis not getting changed so a regular bed adjustment is required anyway.
What happened is when i finally had the unit running the extruder stopped working. After a couple days of WTF i ended up changing the duet wifi board, setting up the new board with the 2 z axis motors sharing the driver 0. No more auto level, something was not functioning properly and now I can just forget that and get printing.
