Topic: Problem with SD2 Extruding

Recently during mid print my SD2 stopped extruding plastic.  The stepper motor is rocking back and fourth in about a 1mm increment.  I have had the printer for several months and I am familiar with most of the basic trouble shooting.  I have checked all of the connections and the extruder still heats up.  I can push the filament through manually.  I tried swapping the z axis and extruder connections at the motherboard to see if the problem is with the motor.  The issue moved to the z axis with that stepper displaying the same symptom.  So I think that my problem is with the motherboard or the driver for the steppers.  I also noticed that the l.e.d. on the motherboard is no longer lit when the printer is connected and on.

Thanks in advance for any help on this.

Re: Problem with SD2 Extruding

Here is the response from SD tech support.  Anyone else have info on this.  Possibly what type of stepper chip and ware to buy?

"Seeing as how the other motors appear to work, I would wager that the issue is one of the stepper chips. If you'd like, we can see about selling you one, so that you might swap it out. Otherwise, there are a large number of suppliers of similar stepper chips.

I hope this helps."

Re: Problem with SD2 Extruding

My printer is still not working after replacing the stepper chip.  It still has the same exact symptoms.  So I guess the only other option is to replace the mother board.  I found a place in California that has reasonable prices and ships very quickly.  They have 2 different Sanguinololu 1.3 boards and I'm not sure witch one I should buy.

If anyone has any insight or experience with this company and these boards the knowledge would be greatly appreciated.
