Hey guys. I think I have an issue with underextruding. Some of my prints have been coming off of the build plate. I added a brim which generally helps but the brim looks pretty pathetic. Any thoughts?

Or maybe it's just a build distance issue?

Functional print: The key to my office desk drawer broke, so it took me 20 minutes fiddling with Autodesk Fusion and then an hour printing at 0.05mm layer on ABS

Printed in Rigidbot
Designed and printed a camera mount for,
- Point Grey Firefly MV Camera
- 12x12x30mm Cross laser module.

The adjustable mount allows tilting the camera around its optical center. Also, the laser module axis goes through the optical center as well. Compatible with gopro mounts.

Recently switched to using Simplify3D as my slicer software and I'm experiencing some weird anomalies. The y axis (bed) will jerk or backlash during the print causing layer misalignment. The pics are simple 20mm cubes printed in vase mode. The first one I stopped about half way through it was so bad. I moved position of the model on the buildplate and resliced and got the second picture. As you can see there are still layer shift issues. I didn't have these issues with Cura. Anyone know what might be causing this problem?

My prints keep shifting up and down and I made shore that the print bed was level what should I do? It is a Rigidbot 2

Haven't touched my RB since the spring, been rather busy. Got it out yesterday to print some feet for a chair, ever still impressed with this machine. Printed impressively well save some leveling and steps tuning. Cannot stress enough how important it is to level your bed. Doing it manually is best if you ask me. Awesome stickage every time with PLA on clean hot (60) glass. The size on this part was crucial so I found that my steps were slightly off. Two 20x20x10 calib-boxes later and I was dead on the 0.5mm mark. That's close enough for what I need. What really impressed me is the lengths people go to trying to keep their filament dry. I live in 100% humidity almost year round and leave my spools sitting on the stock spool bar all the time. The PLA I was using is the original one that came with my RB a few years ago.

For those interested, I just finished posting all the files needed to print the entire cable chain and control panel assembly of The Beast on Thingiverse.

Safety advisory for anyone still using the stock Rigidbot thermistor.

I have 2 Rigidbot printers and have enjoyed several years of relatively trouble free printing. That being said, this is the 2nd time this has happened on one of my printers.

After trying to trouble shoot some extrusion issues, I noticed that once again, the thermal cement holding the thermistor bulb into the threaded portion had failed. I had the exact same thing happen on my other printer several months back. Both times the thermistor didn't fall out of the threaded portion (luckily) but was loose in the socket and making light contact, causing inconsistent temperature readings. I've been using a compatible aftermarket thermistor in my other Rigidbot and have not yet had a similar failure. They may be using a better epoxy compound, or maybe I've just gotten lucky. I put this out there as a warning to anyone using any kind of threaded thermistor. I assume if the expansion rates are not exactly the same for the cement and metal portion, that any thermistor glued into a threaded insert will eventually separate after enough thermal cycles. A mechanical crimp of some sort or peaning over the edge before the cement hardens would be a nice extra layer of safety to prevent it from just pulling free. I highly advise checking the thermistor from time to time to make sure it is still secure and not just assuming it is ok because it is threaded in there.

RBB3 X axis running backwards
I just assembled my RBB3, everything seems fine, except that the x axis homes to the right. I have sort of got around this by mounting the x motor with the shaft down, however this does not seem great.
I guess that I can swap the wires on the stepper, but really was looking to assemble and play.
Any suggestions of something dumb that I might have done?
I can correct this in firmwear, but really don't want to get into that now.
Thanks
David
