Re: Service Bulletin: Thermistor Issue in Aerostruder and Dual Extruder v3 Tool Heads

There's definitely no problem with the thermistor in my Mini Aerostruder. After a number of tests and reading several related posts on this topic, here's the conclusion I've come to: 1.

However, I checked the crimp connectors and they seem fine - When I just heat the extruder and wiggle the wires I don't see any noticeable noise. This makes...

Re: What should we make next?

A Universal Extruder Tool Head Lulzbot has the standard extruder for rigid filament and the Flexystruder for flexible filament. This was fine 2 or 3 years ago, but the market has changed.

Re: Adding an Openbuilds Openrail x axis to a Lulzbot Taz 4/

Cam adjustment frequency I've designed/built/operated systems with cam-adjusted guide bearings ranging in size from smaller than the Openrail units, to significantly larger units. The need for adjustment depends primarily on three factors: 1. Good design -- making sure that the bearing assemblies ar...

Re: Lulzbot TAZ 3??
