Qidi Tech 1 - Replicator 1 clone

[Merijeek]

Alrighty, so I've gone ahead and taken a couple days off, but now I'm back. A SCUBA diver at work wants a couple of the tentacle iPad holders for himself and his son. So, some people are liking things.

I haven't had anything to show off or complain about. However, I've just started printing a couple of these https://www.thingiverse.com/thing:1004996/#files (because I can...) and came across an annoyance that I keep forgetting to ask about. Of course once I've got 10 layers down I realize it's doing it at .1mm, which means it'll take needlessly long to do. Oh well.

How can I change my S3D defaults so that any time I choose PLA profile it turns on the turbofan?

So, finally get some material to work with, even some potential orders if I can get some prototypes done.

Of course I can't get the machine to print to save my life.

Running some Maker ABS on typical settings, bed temp 110 to start, drops to 80 at layer3, 230 nozzle temp, so on....

Will print to near perfection for about 2-3 hours then just stops feeding material. If I let everything cool and start again (with doing NOTHING between mind you) it will print again for about 2-3 hours then stop feeding material.

I have tried everything. Changed what side I was using, changed nozzle and PTFE tubes, changed the drivers out, Even changed the cable from Mobo to the feeding stepper. Same results after everything.
I am at a loss as to what to try next.

Have you tried 225 or 220? I've had better luck with ABS at 220 on longer prints.

230c is my typical ABS temp.

I live in south Texas man, right on the coast. My numbers are usually a little bit of the 'norms' that most are using. It's because its SO damn humid here.....70% humidity is a dry day for these parts.

Hurts more than 3d printing too. I have been a metal worker most of my life, and professionally till my last knee surgery. This is the land of metal death....you leave bare metal over night and it will be rusted to hell the next morning. Only takes about 2 weeks for steel to get pitted around here.

That is a nasty heat, sticky. Up here things freeze and crack up, decicate, shatter. Dam Lake effect snow on top. Still not as bad as Alaska.

Syd, is this the same issue that you had before when you were going to sell your QiDi? As I recall, you never identified a cause, the problem just ceased happening for some reason. Does it now happen with both extruders?

It is not the same issue....
Thought I posted about that, maybe not though. Last time it turned out that I replaced the driver with another blown driver that got mixed in with my spares. But that don't happen any more lol.

Def not whats going on this time. Seeing this on both extruders.


Off-topic a bit...
That fella still doing the nozzle packs on Amazon for good price? I tried to search but could not find em.

Sure, do a search on Amazon for "BIQU Nozzle" or "BIQU MK10". The assortment of sizes is also available there in both SS and Brass.

what is the Vref value you have set on your A&B extruders? If your drivers on that are burning out, maybe raising the value to 127 would help that.

The feeders are still at default, what is 127 iirc.

Found the culprit, was the feed carriage. DO NOT print feed carriages from ABS!!!
Still not exactly sure what happened, but seems like the spring was no longer able to put enough tension on the floating arm. Spring is still as springy as the day it was new so has to be the carriage.

Back to the stock carriage, and its printing, finishing prints...still having some serious extrusion issues. Will post a pic of whats going on now in a bit...gotta get dinner going for the kids right now lol.
