new printer, a few problems...

[michaelkittrell]

I just got my printer working last week... kind of.  It works, it did print, but now I'm having issues.

1.  z end stop not working correctly?

I started tweaking things in the config and in repetier-host, and now my Z refuses to stop even though the endstop is triggered and keeps crashing into my extruder.  I've tried reverting back to the original configs and stuff, but nothing seems to fix my problem.  When I run the "Z breakin" it does a couple moves then buzzes, then moves a bit more, then jams the bed into my extruder (until I hit the reset button so for at least 15s the first time).  The XY breakin runs like a champ and bounces properly.

Anyone have any ideas?  I just replaced my z endstop and ran the m119 test (which does show the endstop working correctly).  

I have v2 of the Azteeg mini x5.  I am currently using the official configs from the main eclips3d site for the v2 board.



2.  z bed only 145mm?

So using the manual control in repetier host, I ran my bed down to the bottom and got 145mm... isn't it supposed to be closer to 200 mm?  I assume this is the fundamental problem with my prints not turning out?


3.  How do you safely power off the printer?  especially in the middle of an error situation.

I've been turning off the PSU... but i keep reading about needing to "power down" the stepper motors before disconnecting the DC.  Can someone tell me how to do that (and where the information is because I've looked on panucatt and google and can't find anything).  There is a play, reset and a hwboot button on my controller (as far as I know).


4.  communications error

I'm not having this problem now, but when I first was getting the printer up and running, I would make it about half way through the XY breakin and the printer would stop printing and stop reptier host would stop responding.  I can't remember how I fixed this  (assuming I fixed it on purpose and not by accident or getting a random bullseye) so if anyone knows please educate me!



Thanks in advance

1. Using M119 in console you can determine if the endstop is pressed or not. If it is not registering, either the endstop switch got messed up somehow or the wiring is incorrect. I don't think its firmware because if it were, it most likely would act as if it were always pressed and only home when you actually press it, then stop when you let go.

2. Nope that's wrong and that is definitely messing up your prints! Either the microstepping for your z axis is wrong (should be 1/16) or your firmware steps/mm for the z axis is wrong. Double check both of these things.

3. Just flicking the power will be fine. It isn't the best to turn off the power when the steppers are on, but it won't cause any damage in normal circumstances. If you are still concerned, you can disable the motors before turning off the power. You can't really do this in an error or emergency situation, but during normal use there is a button in the repetier control panel to do this (or issue M84).

4. That's odd, may have been a drivers issue. The azteeg boards are awesome but drivers can be hit or miss. Also having a properly shielded usb cable can help a ton, even if that doesn't seem like it would be the problem.

Hopefully this helps a bit!

#1 and #2 fixed by the microstepping.  I put my jumper across pins m2&3 instead of m1&2.  Now that you pointed that out I remember messing with it.  see foot, shoot foot, wonder why foot hurts.



#3. Well thats a relief, I kept worrying that each time I turned it off I was playing roulette with a $110 board.

That's an amazing quote, I'll definitely be using that

Anyway glad I could help! Let me know if you have any other questions!
