Sometimes (especially with the ones I use) you need to work the bushing in its collar to get it to 'self-align'. Typically, I stick the bushing into its printed holder and then slide it onto a 10mm rod. Then I work the bushing to loosen it up so it moves a little more freely in its collar...

Bryan, I have converted every axis to sintered bronze bushings and have not regretted it in the least. LM8/10UU's are just so bulky, not to mention noisy. Did you un-bind the self-adjusting bushings in the pillowblock before inserting the rod? That can help reduce binding immensely. Those...

Nick, Hmmm. So the wiring for the Y-axis is known good since you drove the Y-axis using the X-axis electronics. Worst-case scenario here (maybe the last thing you should try). Let's for a second assume that your Y_MIN pin is blown. Let's try swapping to your Y_MAX pin to get this up and...

Nick, post your config.h file

Nick, re-check your Y endstop. Are you sure that it's wired C-NO and that it's connected to SIG and GND. Connecting to SIG and +5V or 5V and GND may cause this issue. Typically this is a spun-around 3-pin endstop connector at the RAMPS board. JNeil, where did you get that J-head from? Is...

Have you seen the TRE yet?

Didn't know if you had seen this or not. Stumbled across it and figured I'd share. https://github.com/alexborro/Marlin-BedAutoLev http://www.youtube.com/watch?v=3IKMeOYz-1Q http://www.youtube.com/watch?v=x8eqSQNAyro

ScribbleJ is just full of surprises! http://www.youtube.com/watch?v=dpdvshOm2w8

Bryan, how many hours do you have on your printer? Check the Z-axis nuts to see if their threads are still well-seated on the threaded rod. http://www.youtube.com/watch?v=4y8GFYylLlM

Easy way to test this out - just flip the PCB and re-test. Your traces are on the bottom and heat-spreader on the top? The traces themselves are hotter than the top copper, and will expand more than the heat spreader, doming the PCB downward. Personally, I really dislike those PCB heated...

I'm not surprised at the variance between heated bed on/off. Even with glass that PCB heated bed will change shape with heat - it's a known issue/feature. http://reprap.org/wiki/PCB_Heatbed What state has more variance in the plane?

I haven't looked at printer prices for a while, but damn that is cheap.

+1 for starting out with a 0.5 nozzle. And you should go check out reprap.org and forums.reprap.org

A picture is worth a thousand words. Maybe a pic of your configuration (without power of course) would help. :) I doubt you really messed anything up - the 328P is pretty rugged, especially when you consider that the pi is only applying 3.3V or 5V to any of the GPIO pins. And those...

Nope, you are correct. 0.03 is a bad layer height. Any multiple of 0.004 will work for your setup. :)

Bryan/Ralph Steps Calculator I'm assuming you are still using the M5 threaded rods (0.8 pitch) and 200-step motors that came with your machine. Assuming that you haven't calibrated your Z-axis (which you shouldn't do) your steps/mm for Z should be 250@full step. If you're running at some...

Welcome back! Where in the Keys did you wind up? The wife and I go down every June for snorkeling and sailing.

Darren, what is the OD of that pipe?

I'd rather have a $25 lmremote board sitting outside than a $70 HM4. Sacrificial anode. I guess it comes down to how risk averse you are. I'd rather spend the extra money to keep my high cost components safe. If that means I have to sacrifice a lmremote board every now and then so be it.

But you're still stuck with having the heatermeter physically tied to the pit. Oustide. That's what I'm trying to get away from. Maybe I didn't articulate what I meant. What I'm saying is that the current lmremote setup is the best low-cost solution for wireless. But you can populate...
