Re: Belt Tightening?

The belts are not a continuous loop, there's a clamp that locks in each end of the strip of belt. It's under the table for the Y axis, and behind the extruder mount on the X axis. Use an allen wrench, loosen the clamp, use a needle-nose pliers to grasp the end of the belt and tug it gently tighter, ...

Re: 1.75mm on TAZ workhorse

As a young automobile owner during the years where the industry transitioned from Imperial to Metric (mostly) perhaps I became overly fixated on proper dimensions for everything -- so when I got my first Lulzbot printer, it never even occurred to me to attempt the wrong size filament! :-D I've since...

Re: material filling in small holes in the design

thing.PNG You made me curious -- so I downloaded the STL, sliced it with Cura 21.08, and printed it on my Mini 1.04 (Polymaker Polymax PLA, at 205C, layer height .15mm, nozzle is the original 0.50 mm nozzle). Not sure what it is, but it printed pretty nicely. So I have to think it's not that your p...

Re: Dual V2 now a boat anchor

Lulzbot doesn't seem interested in selling a lot of parts. But, there are other companies who apparently see that as an opportunity... I think this might be the thermistor you're looking for: https://itworks3d.com/product/thermistor-3d-printer/ [Edited to add: they seem to be out of stock as well......

Re: Auto-leveling presses down bed corners

Yes, the autolevelling is done with a voltage between the washer and the nozzle. Usually, any visible depression of the corner means that there was some sort of plastic residue or such that had to be compressed or pushed out of the way before sufficient force could cause the washer and nozzle to tou...

Re: material filling in small holes in the design

It looks like you're over-extruding right now - which may very well be contributing to the problem. For example, if you're actually extruding 110%, that means you have an excess of 10% of the plastic that needs to go somewhere, and filling in your holes is a great place for that extra plastic to go!...

Re: material filling in small holes in the design

For small holes, I generally have found it best to let the printer fill them in a bit -- especially if I'm going to attempt to thread them. I simply use a drill bit to remove the excess material. My concern with changing the geometry of the part, or with using a smaller nozzle, is strength. The thic...

Re: LulzBot Mini Firmware Upgrade Fail

Yeah, that's probably not going to work. The RAMBO board is like the arduino IIRC - I think it identifies as a different device when it's running (a serial port) but switches to another USB device ID when the firmware loads. This causes issues for VMWare, since VMWare uses the USB device ID as the i...

Re: Cura keeps cooling my extruder

When slicing with Cura, what filament and temperature are you selecting? The normal behavior is for Cura to generate gcode that will set the hotend temperature to a temperature where the plastic is soft enough to clean (for many filaments that's about 170C), then the gcode will clean the head on the...

Re: Why will this bolt not come out?

If this is the original extruder (i.e. not the aerostruder), then yes, the idler assembly pivots on a long screw that has a captive nut. You can't reach that nut, and once it starts spinning in the hole, it'll never loosen. The good news is that you're going to replace that idler assembly, right? If...
