Re: My other printer

I use a new piece of foam each time so I don't do that. I was thinking it was a buildup but I ran a piece of music wire through which being cold pulls out a blob of plastic and it wasn't covered in gunk. I'm guessing the fuzz built up over the last couple of dozen kg of filament since the nozzle was...

My other printer

I'm still printing those structured water devices on my Afinia printer and other than then "natural" filament having a few bad spools it's been plugging along with no problems. Well, today two prints aborted with a jammed nozzle. I ran a wire through it and extruded some more and looked at...

Re: Stepper? Servo? What is this?

Back in the olde days we used to drive mag tape with torque motors. You hook them up to an analog board and tell it how much tension to hold on the tape and it did just that, the motors/electronics put out a constant torque from dead stop to turning fairly fast in either direction.

I run every spool through a sponge now. I just poke a hole through a fresh piece for every reel. I get an amazing amount of ...err... stuff off brand new spools fresh out of the vacuum bag.

Need high quality printing service

For a customer I'm going to need to print one to a few of a mechanical prototype. This would be beyond the normal MAX v2 capability unless the machine is well tweaked. I haven't had time to finish tweaking in my machine, too busy trying to get a couple of customers designs done. I'll have CAD files ...

Re: hot end problems

I don't know if it's the resistors burning in or what, but I redid the PID tune and the numbers are way different than the first time I ran it when the v2 was new. It regulates better with the new numbers.

Re: Dual Extrusion Repetier .91+RAMBO+E3D Chimera

The Rambo can definitely handle the two motors and extra extruder. When I built my v2 I pre-wired it for that. If you used stock wire locations, you'll have to move some and fix in the configuration.h file. I think you have to set the offsets in whatever slicer you use, I don't think there's one uni...
