Stalling problems
Hi everyone!
I am having stalling issues with my printer. Randomly on complex print (currently
http://www.thingiverse.com/thing:2023835)
the cache goes down to 0 and the printer stop for about 30 seconds before
continuing. I have tried to play with the values below without success. Lowering
the print speed and/or segments per second doesn’t seem to help. The stalling
occurred when using a SD card or USB.
My setup: Delta / radds / raps128 / dev firmware (same problem with 0.92)
Print speed = 200mm/s
Acceleration = 1000 mm/s2
Jerk = 25
DELTA_SEGMENTS_PER_SECOND_PRINT = 600
DELTA_SEGMENTS_PER_SECOND_MOVE = 600
DELTASEGMENTS_PER_PRINTLINE = 60
STEP_DOUBLER_FREQUENCY = 80000
PRINTLINE_CACHE_SIZE = 92
MOVE_CACHE_LOW = 92
lowTicksPerMove = 250000
Does anyone have the same problem ?
Thank you!

PRINTLINE_CACHE_SIZE = 92
that is quite high. Do you still have memory left?
MOVE_CACHE_LOW = 92
That should be lower then cache size or firmware will start reducing speeds from the beginning. This is to protect buffer from running empty by reducing speed with short lines. That value will always trigger the condition.
What disturbs me is 30s from sd print. That would be a step missing the timer so it needs to wrap around (ok that would be 53seconds so how sure are 30s). SO maybe it is just memory running out causing stupid things. So check that you have 1-2kb free ram at start.
