Basic Troubleshooting - SSD 3D Printers

Remember, the 3D printers at SSD should only be used by trained members. This page is only intended to provide some basic hints for solving common problems with printers at SSD. We sometimes hold a workshop titled "3D Printer Troubleshooting" which provides in-depth coverage of the parts of a 3D printer and more comprehensive discussion of common issues and prevention.

What should I do if something is broken and this page (and others) doesn't help? Notify the Boulder Hackerspace email list or privately email a member you know. Do not be embarrassed! Machines break all the time, especially machines that run software, and 3D printers have all these traits and more!
What is the Octoprint login? The password is written on the whiteboard in the printer room.
Cannot connect to Octoprint server at 192.168.1.13 on port 5000 or 5001 1. Check that the Raspberry Pi is powered on and has an active Cat5 cable (ethernet). 2. Reset the RPi by unplugging it, count 5 secs, plug it back in. Try pinging 192.168.1.13 from another machine.
Cannot SSH to Octoprint server at 192.168.1.13 Check that the Raspberry Pi is powered on and has an active Cat5 cable (ethernet). Try to PING the RPi at 192.168.1.13.

When I try to connect to the printer, Octoprint seems to stall. 1. Make sure the USB cable is securely attached. A loose cable may show up in the list of available ports, but it will fail to connect and transfer data reliably. 2. Make sure you are connecting with the right _baud rate_. The default on SSD printers is 115200. When I check the "Terminal" tab to see what's going on, there is a bunch of junk data.

I can connect to the printer and issue commands, but it doesn't obey. 1. This machine has a power switch. Check that the printer is turned on. 2. Make sure the USB cable is not loose.

The print nozzle tends to collide with filament that has already adhered the glass, and peels it up, thus causing the print to fail. In at least two different situations this was caused by an improper extruder flow rate (steps-per-mm for E axis), specifically too much flow. The extruder may need to be calibrated. There can be other causes. Talk to a tool expert. This is not caused by improper bed leveling. Adjusting the bed level may seem to affect or fix this problem, but that is just a distraction.
