Threaded rod wibbleywobblytimeywimey madness

Okay,

So, I’m pretty sure one of the threaded rods on my 3d printer be quite pissed… I have three questions:

1: What would the best practice be for checking the straightness of a threaded rod.
2: How drunk can a threaded rod be before it jams your printer.
3: Umm… Any lonely threaded rod requiring a new home about the space?

What I have tried to do is compare the threaded rod against a plain rod which I believe to be relatively straight, and rolled on the desk, yup looks like it’s out be at least 2mm. I’m so smart.

Thanks for reading, much love, <3

P.S. Should I buy a couple of lead screws and convert the printer to use them ?

I reckon mine are at least that out, and it doesn’t seem to make any difference.

Pop it on an anvil and tap it straight with a rawhide mallet :wink:

Of course the best thing to do is convert to lead screws, but it depends how much printing you do, i suppose.

thanks for the info, yeh hmmm… I dunno really not really got any prints in mind to be honest.

Maybe I will print a dollo printer at some point which is a lot of printing.

Role it along the table saw bed

Okay sounds like a good idea, I will do next time I’m in. Thanks.

I understand that logically a lead screw must be better than threaded rod, in practice it doesn’t seem to make any difference…
