I am reaching out to anyone with spare Printrbot hot ends (1.75mm filament, 0.4mm tips) who might be willing to get rid of them (hopefully somewhere near me in the DC metro area). I appear to consume these with some regularity, since I have some prints running almost 24+ hours. So far, I have eaten through 4. Before someone tells me I’m doing something wrong, well yes, for 2 of them I was. The other 2 I think I just wore out. The most recent one just got clogged after running for 10 hours and then another 10 for a second print and finally died on print 3 about 5 hours in. So if you have hot ends you want to unload, please let me know, and thanks in advance. I am willing to take used working nozzles before I start burning more expensive NEW working nozzles.
Send me your address and a note and I’ll ship some slightly used ones for free w extra nozzles. I have an accumulation from in house projects 
Brook@printrbot…
Thanks Brook!!!
Now that’s support.
The best kind!!!
@Brook_Drumm any word on those hot ends? BTW, I have a special request for an UBIS all metal hot end (no PEEK anywhere). Is that in the pipeline.
I sent 5 hotends on Friday w extra tips
I have used Ubis 13 hotends: all metal, no peek. I stopped selling them b/c people would misuse them by neglecting retraction settings and leaving them hot w filament in there- instant and difficult jam. You have to feed and care for your bot w the all metal version. 10% of people would jam them up so I bailed. They still work great. Let me know if you want to try them. They are good to 300c then the thermistor starts drifting above that.
@Brook_Drumm oh God yes. I am almost done with my current giant print project and I was debating an E36 mod. I want to do the same to the Play.
And @Brook_Drumm , many many thanks.
I’ll round up some 13s and get them out.
Anyone else want to play?
Brook
@Brook_Drumm you rock sir.
@Brook_Drumm just FYI the nozzles arrived. You, Sir, are the bestest. FYI, the extruder motor faceplate tends to ‘wear out’ in that the screw holding the extruder lever arm seems to stop wanting to screw in tight (as if the threads in the faceplate wear out). I have already cannibalized another motor for its faceplate and would hate to have to do that a second time. For now, I think I can manage but just wanted you to know. I might tap an M4 to replace the M3 at this point.
Not sure about tapping an m4 into the motor. If o strip one screw, I rotate the motor clockwise 90 degrees and use the unused screw hole
Might actually rotate the faceplate rather than the motor. Is this a common thing with steppers? I know aluminum is soft and all that, but surely threads can take a better beating than that.
There’s not a whole lot of material in the face of the stepper, I think the screw hole is only ~4 mm deep.
This is a common enough issue that there’s an official PB support video about it.
Yeah that’s what I figured. There are other avenues of course and I might put the old faceplate back on and effect a repair of my own on all 4 holes
