Steve's RepRap Journal: December 2008
http://sdreprap.blogspot.com/2008_12_01_archive.html
It's So Crazy, It Just Might Work. Saturday, December 6, 2008. Yesterday, one of the Y belts slipped again. This caused the carriage to skew slightly. Which caused the Y flag to miss the opto. Which caused the carriage to crash and snap the Y flag. I readjusted the Y axis yet again and replaced the Y flag. Currently putting everything back together. Apparently, on putting it back together, I swapped the pins on the extruder motor. Caused a bit of confusion for a while but no damage. What I'm Working On.

Steve's RepRap Journal: March 2008
http://sdreprap.blogspot.com/2008_03_01_archive.html
It's So Crazy, It Just Might Work. Saturday, March 22, 2008. Blobs #2 and #3 both broke free of the base before the build completed. This prompted me to search for a substrate that would hold the build in place and be relatively easy to remove afterward. Tried a bunch of things, most of which don't work. Now I just need to find a way to make flat sheets of polymorph. Posted by Steve DeGroof. Thursday, March 20, 2008. It's a bit wibbly and it leaks. Definitely not toast-worthy. The X, Y and Z scaling's pr...

Steve's RepRap Journal: February 2008
http://sdreprap.blogspot.com/2008_02_01_archive.html
It's So Crazy, It Just Might Work. Friday, February 29, 2008. Spent the evening drilling out the corner blocks. Four vertical holes with a 5/16" bit (roughly 8mm). Five horizontal holes (one around back) to clean out the trapped nuts using a 5/32" bit (roughly 4mm), followed by an M5 screw to clean up the threads. Posted by Steve DeGroof. Also noticed that the diagonal tie brackets don't have trapped nuts. Not sure how I'm going to attach those to the frame. I'll have to improvise. Posted by Steve DeGroof.

Steve's RepRap Journal: April 2008
http://sdreprap.blogspot.com/2008_04_01_archive.html
It's So Crazy, It Just Might Work. Friday, April 4, 2008. Having a lot of trouble getting a reliable extrusion. I had two PTFE barrels, both of which are distorted too much to be useful. I had two extruder clamps (one quick-fit, one regular). Both have suffered heat damage. I'm beginning to think that the current extruder design just can't do HDPE reliably. It wasn't really designed to do it in the first place. Posted by Steve DeGroof. Subscribe to: Posts (Atom). What I'm Working On.

Steve's RepRap Journal: Best Laid Plans
http://sdreprap.blogspot.com/2008/08/best-laid-plans.html
It's So Crazy, It Just Might Work. Tuesday, August 26, 2008. Tried printing the " motor-holder. Model From left to right: 1) Y belt slipped a bit, 2) Y belt slipped a lot, 3) actually printed reasonably well. This a first attempt at " gear-bush-holder. Which I modified (hopefully correctly) to print without support. About 1/3 of the way through, the Y motor coupler came loose. Posted by Steve DeGroof. Subscribe to: Post Comments (Atom).

Steve's RepRap Journal: November 2008
http://sdreprap.blogspot.com/2008_11_01_archive.html
It's So Crazy, It Just Might Work. Sunday, November 30, 2008. I tried an experiment in support material. The idea was to use the same extruder for both support and build. The host software allows you to do this but it's a relatively recent change. It's not available in any of the official releases (I think, correct me if I'm wrong on that) but, if you build from the SourceForge source, you can do this. ExtrusionInfillWidth(mm)=2.4 (instead of 0.8). NumberOfShells(0.N)=0 (instead of 1). 4 Position and ori...

Steve's RepRap Journal: Y Axis Cleanup
http://sdreprap.blogspot.com/2008/11/y-axis-cleanup.html
It's So Crazy, It Just Might Work. Sunday, November 30, 2008. I think I found the Y axis problem. It looks like the X motor mount was catching on impefections of the rod it rides on. Two points seem to be a problem:. 1 The block that constrains the lower side had a sharp inside edge. This seems to have been due to the molding process. Mine are molded parts, not printed or laser-cut. I removed both of these blocks (one on either side of the motor) and ground down the edges. Posted by Steve DeGroof.

Steve's RepRap Journal: Mod Squad
http://sdreprap.blogspot.com/2008/08/mod-squad.html
It's So Crazy, It Just Might Work. Monday, August 25, 2008. Some modifications I've made. Blobs of polymorph on the X and Y carriages to keep them from wobbling so much. A bent paperclip to keep the filament out of the way. A piece of plastic tubing clamped to a bookcase to feed the filament. Posted by Steve DeGroof. Subscribe to: Post Comments (Atom).
