Thanks,
I don't believe the extrusion motor is getting too hot, don't have the problem with PLA.  Pulled off the heatsink and it looks like it's about 1/2 covered with the white thermal past, and it's screwed on pretty tight.  Will get a temperature of the extruder motor next time I run it.

Appreciate the response.

I had this problem too.

Is your Extrusion motor very hot?!!
If yes, it is the problem.

I had mine partially resolved.

I guess during the production process at SD, a big overlook by the assembly guys. The Heatsink to the extrusion Stepper is not contacting at all. Take a look at the pictures.

Even the thermal paste is not spreading since the heatsink is not contacting the stepper motor. Pls improve.

I had refix it with 3M Thermal Pad. Now the stepper is cool as a baby.
Normal Thermal Paste will do as well. No more missing step on the extrusion stepper.

I hope this helps..
Cheers

Do you try to apply more tension..?
If it skip step after increase tension, I am guessing it's stepper driver calibration. Perhaps a relook at the trimpot at the Stepper driver? I only manage to extrude at 9mm/s speed with success result. Going for E3D soon. But first to test out the Jhead MKV. Brought 2 set, hope they work.

A google search for "E3D" returns:

1.) www.e3d-online.com (E3D's site, but they're UK based)
2.) www.filastruder.com/products/all-metal-e3d-hotend (my site, I'm a distributor)

I'm running the ABS at 205 and 60 mm/minute.

No signs of blockage.

That's fine. If anything, 205 allowed the threads to deform slightly, creating the gap between the PTFE and brass.

I run MG94 ABS at 150mm/s, 200C through that stock SD hotend. With the E3D I could probably hit 225mm/s.

PLA usually feeds easier than ABS - it gets "thinner" at its melt temp and is easier to force through the nozzle. The following could cause your issues:

- A jam, typically because a gap has formed between the brass barrel and the PTFE liner
- A clog, caused by debris in the nozzle
- Insufficient melt temperature
- Excessive feedrate

What temperature, what feedrate?

E3D is regarded as the best hotend, but I have also put ~40kg of ABS through a stock Solidoodle hot end.

And it most definitely fixes it.  Just in case you want the opinion from someone that doesn't sell them.
I like them so much I own three of them and two of them are still in the package.
My bet is on a gap between the brass barrel and the liner.

How did it fix it?

I had previously cleaned the drive gear and had started the feed with the tension just tight enough that it would touch the filament, then tightened it as the feed progressed.

I had also completely cleaned the head portion including the peek and made sure that the barrel was tight to it when it was reassembled.
