Pauses during print

[rbisping]

gonna post this on here also. I am still having issues (pretty major
now) with pauses during print.

Using repg9 or 10
mb firmware 1.4 or 1.6 (tried both with same results)
extruder firmware 1.6 though ive tried 1.1 and 1.4
skeinf 5
printing from software or from sd card.

I did notice on one object that consistantly stops in the same spot
that its not a total stop at least not from the sd card it moves the
axies about one step every 1.5-2 seconds.

I notice that there is a message in the comm box but for the life of
me cant remember what it is but its something like insufficent load
but that isnt it. I'll try writing the error down next time im
printing (at work right now).

thanx in advance

try changing the Ethernet cable connecting the two boards and check
for their loose connection...?

Sounds like SD card corruption.  Try reformatting your card.

then why does it do it when i print off of my computer?

3 different issues with similar symptoms:

1: Pauses while printing from the computer: the USB to serial connection is just too slow for this kind of work.  The motherboard exhausts its tiny buffer and has to sit idle waiting for the next set of commands to come across the cable.

2: Long pauses, stops, or just wacky behavior while printing from SD cards: filesystem corruption (firmware 1.4 corrupts large cards' filesystems frequently, 1.6 infrequently) or filesystem fragmentation (all firmware versions).  Reformatting your SD card frequently is a good idea.

3: Short pauses while printing from SD cards: firmware 1.6 issue.

The tradeoffs:

A: Printing from the computer just doesn't work for a lot of parts.

B: Firmware 1.4 corrupts large SD cards, especially the ones that MakerBot has been shipping recently.

C: Firmware 1.6 has frequent short pauses while printing from SD cards.

If you have a small enough SD card that 1.4 doesn't corrupt, then go with 1.4.

If you have a larger SD card (like me), then go with 1.6.  You'll just have to live with the short pauses for now.

No matter which firmware version you use, reformat your SD card often.

very strange, can you tell us more about your computer? vendor, OS, last time rebooted, java version installed, anything else you can think of.

We don't ever get pauses since I switched mobo back to 1.4, running from debian or os x 10.6.

Dell 17" laptop (forgot model, 2GHz, 2GB, a little over 3 years old), Windows XP, suspend to disk every night, complete reboot around once every 2 weeks.

You don't print from an SD card?

Switch to repg 008. I used to have lots of these problems, until I
switched. I now use repg 008, mb 1.4 and ex 1.6. I've also found that
motor noise is a common cause of problems like this.

running off my laptop, win xp rebooted occasionaly.
Note: reskeind one of the files i had major problems with using sf6
and it worked a lot better. still a failed print but that was a
extruder shut down issue.
not sure if it jammed or striped the filiment or if it was another
glitch.

question: what size sd card is considered usable i think im using a 1m
right now.
the error i keep getting is "payload not big enough" and so far i
havent been able to find anywhere in the software that this is being
generated.

mb 1.4 isn't an option for me because of my 1GB card :(

Todd

[Jordan Miller]

nope. we haven't ever printed from an SD card. no build hiccups over usb!

my guess is windows-java problems... can you try from a mac or linux box?

Where's the size break? I have a couple of 256MB cards I was planning
on using, or I have a 512MB and a 1GB MicroSD with adapter I could
use.

Anything up to 2GB should be fine; I'm using a 2GB microSD in SD
adapter.

Now that RepG writes directly to s3g format I'm able to use my OCZ
CrossOver as sneaker-net. (http://www.ocztechnology.com/products/flash_drives/ocz_crossover_usb_2_0_flash_drive
)

I've been having the same problem with pausing, and getting the same
"payload not big enough" error.

Do either of these apply for you?
* You've got "monitor temperature" checked off in your preferences,
or
* You've left the control panel open while you're doing your build.

If so, I think this post might explain it:
http://groups.google.com/group/makerbot/browse_thread/thread/e53b9a9c233bf4b8/acbaffab1ed3de64?lnk=gst&q=payload+not+big+enough#acbaffab1ed3de64

I think I've been doing both of these things, going to see if turning
them off fixes it tonight.

FWIW, closing the control panel before starting builds cleared the
payload errors on #97.

The newer versions of RepG disable the control panel automagically upon building for just that reason.
