Idex, parking not in the center
I assembled v-core 4 idex 300, after parking in the home position the print head is not in the center of the table, on the Y axis it is also not in the center, when calibrating VAOC it is possible to bring the head to the camera only with the parameter position_max: 450.000 in stepper_y, also when calibrating T1 an out of range error appears on the X axis
Z banding on large prints?
Hi I noticed some strange banding artifacts showing up on large prints and not sure what could be causing it. Flow and PA has been calibrated for the filament and I have not noticed this on smaller prints before.
Solution:
Realy curious on your sliced files. If there is a repetition in the bands, you might want to look and see in the gcode view of your slicer if there is something similar on (for example) cooling on/off, rotation (extruding clockwise vs anti-clockwise), flow, speed. I sometimes see these bands as well and can see on the gcode view for cooling fanspeed a similar patern... switching it on or off over the whole part could tell you someting?
Also, Near the corners it seems to be much better. Could this have to do with pressure advance, properly tuned (as you wrote) and that for normal extrusions you have a slight over extrusion?...
VAOC Cam freezing
Hello people. I just received the replacement camera sent from RR as the first one was defective (it was the board, hance I haven't used the second band cable and camera sensor)
Now I'm trying to go through the VAOC calibration, but the image from the camera blinks all the time (loosing connection and then restoring it every second or two) when in the WEBCAM tab. This is not bothering me as it's not happening when starting the VAOC calibration, but I still can't finish it. The image from the camera freezes randomly through the process and besides the toolheads are moving and the diod is able to be switch on and off, I'm not seeing that as the image is frozen. Firmware restart or Restart is not helping. I need to restart the whole printer and then I'm able to start all over, until it freezes again. The closest I could get is setin T0, but when summoning T1, the image froze again. Any hint's or tips how what am I doing wrong or how to solve that?...
