Well, I’ve had my TAZ6 for a couple years now, and have honestly used it very little since unboxing it and setting it up due to the miserable excuse for self levelling they put on that printer.
Now don’t get me wrong, I’m a fan of Lulzbot printers, have six of them in fact… but this TAZ6, it’s the one printer from them that I truly regret having bought. I’ve been relying on my TAZ5 printers exclusively since these past years… but recently, all but one of them have dropped off due to board failures. So, I’ve had to go back to my miserable TAZ6.
I’ve come up with a ghetto way of getting the perfect level every time. Now, I’m sure there are ways of disposing of the conductive levelling that plagues this printer from being anything but a paperweight.
Not having the time to mess around with re-building what should be a reliable printer, I came up with a quick and dirty solution that’s giving me perfect levels every time…
To do this, what you need are some good magnifiers (if your eyesight is anything less than perfect… like mine are), an IC clip soldered to a short run of wire (about 1.5’ will do) and the other end goes to a probe (like you’d find on a multimeter). I used silicone jacketed wire as it’s very light and flexible.
Clip the IC clip to a washer (I used the front left). Then let it go through the motions of trying to find level… except, don’t rely on the conduction between the nozzle and the washer as it goes through the four points.
Keep your eye on when the nozzle touches the washer (this is where the magnifiers come in to play), then tap the print head with the probe. Do that on all four corners (every time you print… GAWD) and your prints will work out fine every time.
Lulzbot has certainly guaranteed the resale value of the older printers I tell you. Unless they come up with a better (and actually reliable) solution for leveling, I’m going to stick to buying old TAZ5 printers for my needs.
Hope this helps some of you who still put up with the TAZ6’s miserable levelling.
