More Refinement and Useful Parts

I continued to tweak the Z offset and eventually got it right. Changing retraction distance also resolved the stringing issues.

While tweaking stuff I was print a different filament spool clip which also turned out to not be too great. They're small so it's not a big deal if they don't work out.

I finally found a good filament spool clip. It's called Khalessi Clip and it works great on all of the spools I have. I eventually set up a gcode file that prints six of these at once and still use the Mini Delta to print a batch as I acquire more filament.

I had found a set of 'legs' to raise the printer up some and provide a spot to put the SD card holder/extension. They had a test sizing part (how did they know?) and I found that 101% would do the trick with the new gcode prefix provided from a wiki link. A little stringing but it will be OK. Have to wait for the cable now.

Next on the useful list was an unexpected surprise. My friend Dave has an HP 2200 laserjet printer that the manual tray door won't stay closed on. It's a common problem and you can't buy (for a reasonable price) a replacement door because they have all broken. I figured it was worth a shot to search Thingiverse just in case and was pleasantly surprised that someone actually had developed a solution for this problem. It's a tiny part that wedges in the side of the door and provides a new way to keep the printer closed. It was a 5 minute print and I used a piece of the PolyLite Red that had broken off on an earlier print. I only had about 30 cm available but it was enough (it's a tiny part). It's working perfectly!

I decided to print the other two legs (it's a triangle so only 3 legs) - one with 6mm holes for switches and one plain. It turns out that the one with the 6mm holes really has 12mm holes and wasn't useful. I caught it early and cancelled it. I just printed 2 plain ones to do the job.

The cable for the SD card came the next day so I installed the legs and the SD card cable. It's MUCH easier to handle full sized SD cards - actually a micro SD card in one of my many adapters.

Just for reference, the Mini Delta is VERY picky about SD cards. I have several of various sizes and I can only get one 128MB card (came in my Garmin GPS) and a 16GB card that work. I have no idea why only these two work and it's not the card size - I've tried a 256MB, a 2GB, and a 8GB card and could not get any of them to work. They do work just fine on my Ender 3 though.
