You were both correct. My axis were not square, of course once it's pointed out it was really obvious! I suspect this was the result of a lot of moving around and transporting in the last few weeks. Thanks so much for the replies and the troubleshooting, thanks!

I built a Smartrap and I've mostly been using it to print smaller parts. I tried printing a large bracket, and I'm noticing something really odd. namely, the part prints at a very noticeable skewed angle. If you see that attached photo, you can see the noticeable angle in the print (the two walls should sit at 90 degrees from one another)
I tried re-exporting and re-slicing the part and I'm expe

Thanks for the information and the advice. I will try to tighten up the belts and see if this doesn't solve the problem.

Over the weekend I updated to slicer 1.2.9, and I'm experiencing a new issue as a result.
This is a print of this part off of thingiverse. Printed using the settings recommended on the instructions tab.
a was sliced using 1.1.7. The settings worked great, everything was nice and smooth.
b was sliced using 1.2.9 using the exact same config file as I had used in 1.1.7. Nothing changed on the pr

I solved my own problem. The Z Probe Offset instructions here did the trick:
I've got a great print going right now. Thanks for the advice and input everyone, it looks like I've got a great working smartrap on my hands.

Celeda -- Belt tensions is pretty tight, tighter than on my Kossel della style printer, that doesn't seem like it.
Duranza -- Nozzle size is correct, and extruder steps are correct per rcjoseb's great guides on calibration. How would I know for certain that one of the axis is skipping steps? Any other things to look/listen for?

So here's a new problem I'm encountering, I'm finally up and running pretty well, and for the most part my prints turn out okay...once they get past the first few layers. See the photo for what I mean.
It appears as though the head is dragging along on the first layers, I suspect it has something to do with the z-offset, but I figured I would check with you all for suggestions first.
Thanks in

Hey Djinn -
I understand the point you're making, but I'm not even exactly sure which settings I should even be halving.

I finally received my replacement driver. I removed one of the jumpers under the extruder driver to set the board to 1/8 stepping; but I cannot find the steps in your guides for setting the firmware to 1/8 stepping for the extruder.
Thanks in advance!

Thanks for the link, I guess I wasn't counting on so much math for this build! I got spoiled with that mostly pre-configured delta I built.
So, double check my math?
Calculating my e steps...
from Triffid Hunter's Guide: e_steps_per_mm = (motor_steps_per_rev * driver_microstep) * (big_gear_teeth / small_gear_teeth) / (hob_effective_diameter * pi)
Using that formula: (200 motor st

Thanks for the link. So I remove the right-most jumper, and that's it? My extruder is now in 1/8 step size. Are there any changes that need to be made to the firmware?
And yes, I ordered a 5 pack of drivers for future mistakes. Lesson learned the hard way...

In trying to look through the ramps and make sure I had everything setup correctly hardware wise I installed the extruder's A4988 driver backwards, thereby frying the driver. So, I've got a couple more on order.
Until then, I do have a question, how do I set the extruder's stepping to 1/8 from 1/16? I can't seem to find a clear method for doing this anywhere on-line?
Thanks again rcjoseb!

I'm going to follow the in-depth calibration guide that rcjoseb posted and get back to you all.
rcjoseb - I think you might be on to something with regard to my torque settings and the micro stepping, I'm going to follow your guide and go from there.
Thank you so much for the quick responses and ideas Idanut, djinn5150, and rcjoseb!

1 - Skipping. Filament is not being chewed up at all.
2 - I have tried lower temps and no luck. That said, I have another printer, a delta style, and I've used the same filament I'm trying on Smartrap on that printer and it only requires me to print at 180C, so it feels like it's something with the hotend? I had not considered the PTFE might be swell, so you think it's work trying t

Hello All -
Long time lurker, first time poster. I've been building a Smartrap ( ) for the last couple weeks, and have been referring to everyone's posts here for quite awhile. There's a lot of good information here, so that's why I figured I'd finally post my own conundrum: I've finished the build, and the build is sound, software seems to work just fine; I am have having one problem though:
