New Firmware
Jarek
curious as to what it does. Does anyone know a website where I can
view a changelog of the firmwares?

controller board died. I don't believe the firmware did that, since
i've been having issues for some time now, but I was not able to get
the heater to get up to temp.. the PWM seemed to level off way too
soon.. i.e. I had the temp set to 240, and it would only get to 170.
Other than that, it seemed to work in concert with the new mobo
firmware well, though I couldn't really test it as my extruder
controller borked shortly after.

you say your controller "Borked", you may have to get a little more
technical or talk down to me what ever the case may be. If I were to
guess your barrel is not heating, and that can be a few different
things.

Been running a MakerBot for about two weeks here.. Been making parts
for a mendel, and started having issues where the x/y would pause and
the extruder would keep extruding, resulting in blobs that ruined the
print. Tried everything listed in the makerbot FAQ including moving
the machine, turning off fluorescent lights, twisting stepper wires,
rewiring to keep stepper wires away from comm wires, new ethernet
cable for connection to extruder, removed optostop cables, tried
different ports, looked for solder issues, etc. Tried the newer
firmware that was out, found that 2.0 a1 caused axis inversion issues.
Moved back to 1.6 on the motherboard, and 2.0a1 on the extruder, which
seemed to mostly fix the problem. It would still pause occasionally,
but only for a second, then pick back up.
A few days ago the extruder started having issues during a print, the
filament was buckling in the extruder even though the nozzle was to
temp. Decided to rebuild the nozzle. Tore it apart, cleaned everything
perfectly, redid threads with a tap/die, installed new MakerGear
HeatCore, affixed thermistor to nozzle, installed new PEEK barrier,
etc. Restarted printing, worked fine. Installed a .01uf cap between
the motor terminals to try and lower EMI output from the motor.
Yesterday I found the new firmware was at release 0 now, Tried it,
axis inversion problems were fixed, but extruder now would not get up
to temp. Was getting up to 170 when set to 240. Went back to old 1.8
firmware, temps resumed normal operation. Tried to print, same
filament buckling issue happened again. Rebuilt extruder a second
time, cleaning everything. Reinstalled, and it was still having this
issue. After about 5 mins of testing after the second rebuild, I
noticed the extruder had turned the drive motor off, and the temps
were falling. I reset the board, rewrote the firmware, and tried it
again. This time, the motor only came on for about 5 seconds before
going off, and it seemed to reset, the way the temps began falling.
Tried it a third time, and it just blipped on for about 1/2sec before
shutting down again. Lost comm when this happened as well.
Every time though, it's able to get right up to temp with no problems.
Plastic oozes out of the tip, but i can't get the plastic through.
Extruder controller will not turn on the motor any longer. I don't
know what the issue might be with the controller.. not sure if an H
bridge is burned out, we have a bad solder joint or something else is
wrong. I'm going to be trying my extruder controller (techzone remix)
that I got for my mendel to see if that works properly. Worst case i
plan to mount up my Wade's extruder with the heatcore and run that
with the mendel extruder controller running makerbot software.
Any ideas are appreciated. I doubt it's the firmware as when it failed
the last time, it was back on 1.8 - heated platform support.

from another voltage source or maybe the fan port just to rule out the
motor? Did the problem get worse after you added the capacitor, it
seems that way to me? Below are some links for motor suppression. If
your h bridge is bad there is a second one on the board you could
trans plant or find out if the firmware can run that one instead. Did
you try your other parts?

one tries is the R1 - 180 ohm resistor the wiki says
"Optional Component: This is the termination resistor for the RS485
comms. The motherboard is located on one end of the bus, and only one
extruder at the end of the bus should also have a termination
resistor. You can remove it or omit it if you have multiple extruders
and at least one has this resistor in place. This component can be
placed in any orientation. "
The key line here is "at least one has this resistor in place". The
link below seems to confirm my theory. If you have ever worked with
the old coax network cables you had to have a resistor at each end for
it to work I think this is a similar situation. If I ever have this
issue this will be the first thing I try. One thing that does puzzle
me is why is this problem not more wide spread.

temperature. My extruder was set to 230 but only ever got to 175, and
my platform was set to 100 but only got heated up to 75. Rolling back
to the previous extruder firmware returns my Makerbot to working
order. Anyone have any idea why the new firmware has these issues?

Oh thanks for the gears people get a kick out of those and I'm asked
what do they do.

properly now. However, the extruder is still turning off. I took a
second extruder controller from my RepRap kit and hooked it in, tested
and it does the same thing. The motor runs when hooked directly to
12v, however, as it bogs down it pulls up to 900mA.. I'm not sure if
that's too much for the supply to sustain, but the other brand new
board i have does the same thing, it resets. I also tried a different
ATX power supply, but I was having the same issue. We ordered a new
gearmotor in case this one's having problems, but for now i'm trying
to convert it to a Wade's geared extruder just so we can get the rest
of the Mendel parts printed. Having issues there as well getting the
firmware to work, but that's a different thread..
And yes, to answer your previous question, i had tried both SD and non-
SD card prints.. no difference in the amount of pauses. The resistor
is an interesting idea though.. I didn't assemble the machine so
that's a possibility, since the optos are disconnected and the
resistor does not exist on the controller. I'll add one in and see if
that helps us out after I get this other extruder going. Thanks for
the ideas!
