Welcome to the SeeMeCNC Community

Thanks for all the quick replies, folks! I really appreciate it.

Hey all, A mishap happened over Thanksgiving and the tab my layer fan attaches to has broken off (I'd post a picture, but the printer is at work and I'm at home right now). For now, I've just put it on one of the other two tabs, but I was wondering if there are any good replacement/upgrade effector ...

I just found the error, and I feel really dumb. Backstory: after the first calibration, I accidentally deleted my macros. No big deal, because I've already calibrated. So, I have to recreate the macros, and to do that, I copy and paste from the manual to save time. So here's where I make my mistake ...

Well, that's definitely part of the problem. The top bolts on the z tower were loose. Now to retry calibrating...I'll update as soon as I'm done.

I am using MatterControl, btw. Here are my measurements:
X Tower: +1mm
Y Tower: 0mm
Z Tower: -1mm

I will also switch those arms around now. Now that I've seen it, I can't unsee it.
Thanks everyone for your help!

Mhackney- are these good?

I began recalibrating by resetting all the adjustment screws to the default position shown in the manual. I also changed the Horiz. Radius to 130 as per geneb's suggestion. After getting the Z tower properly calibrated, I moved on to the Y tower, but I have loosened the screw almost to the point of ...

Correct.

In an effort to get back to square one, I reset the carriage screws and changed the delta radius back to 126.85 through the eeprom. I haven't changed any other firmware settings.

I'm in Chicago. I'm open to a Skype session at some point. Is there any chance this could be a firmware issue? The thing that is so weird is that it worked perfectly before.

The x and y towers are a hair out of true with the bed. I can just barely see daylight at the bottom of my square with it flat on the bed and the top of the square on the tower. I am super stumped where this coming from. The belt ends don't really interact with the switches at all, even though they ...

The z tower belt is a little off-center and might be rubbing a bit. Could that be the cause of all this?

Here are pictures of the tower tops and carriages. Measurements of towers are:
X-26 13/16"
Y-26 13/16"
Z-26 3/4"

No problems with the endstop switches. They are solid and they return H/L values as expected. I returned the set screws to their starting length and re-zeroed the Z axis. When I run the tower calibration macros, the x and y are about 4-5 mm above the platform while the z pinches hard. Here's a photo ...

ZakRabbit- I rezeroed the z height and went through the calibration sequence on p. 240 of the build manual. mhackney- It seems like the all the pulleys on the steppers are tight. Also, when I run the "Bed Center" macro the nozzle is a few mm toward the z tower of the center of the platform. I ...

Hey all, this is my first post. We just bought two stock Rostock Max v2's for the college I work for. I've assembled one of them and did some test prints that came out lovely. I tried a larger diameter print and realized that the nozzle pulled up a little at the front and pushed down a little at the ...
