what the heck happened, left printer head behaves different
Posted: Sat Jan 21, 2017 1:10 pm
All was going well with my qidi tech I, just the other day I aligned the two extruders, and ran the attached script to determine what values in the fw to set for getting the two heads in alignment (following sailfish manual). I don't remember if I printed from the left head since then or not. I tried resetting the printer to defaults using the green with no success.
now I can't print at all from the left head without crazy things happening (s3d:on cancel print head tries to go left forever, or RelicatorG print just cancels itself before it starts)
here is a video of the problem: https://youtu.be/2LMjBBUoRSk
in simplify3d:
reset completely, stock qidi tech I profile, adjusted extruder temp and bed temp
right side print of 10mm box - as expected, sweep across the front, goes to printing
left side print of same profile with only change being left extruder selection - head stays to right of bed, sweep doesn't move the head, extrudes into the air, bed doesn't go to the correct height, starts printing, when I cancel the bed goes down, head goes to the left and tried to keep going past the end of the bed & the stepper starts skipping
In ReplicatorG:
right side: lowers bed and moves head at a reasonable rate, warms up and starts printing
left side: bed goes down really slow, heats up, then bed goes up and the printer stops.
I attached the code versions of the files from S3D. simple 10mm cube.
any help is greatly appreciated!
