Problems after upgrading 3.4.0 to 3.4.1
-
After upgrading my Duet3D Wifi v1.04 from 3.4.0 to 3.4.1 I am facing strange issues.
-
The X0/Y0 seems to have been moved. My start-gcode homes x and y, which is slightly off the bed and then moves to x0/Y5 to print a prime line. On 3.4.1 this line is printed in front of the bed!
-
Starting with 3.4.1 every 90° corner (which have an additional radius of 1mm!) is printed with a large bulging. It seems as if the noozle moves 0,5mm beyond the corner and then moves back in a curve back to the 90° line.
This is what I get with 3.4.1:
This is very annoying. I have not changed the gcode, nor the configuration.

These are the 3.4.0 corners:

Please show us your gcode. Config.g, homing files, start.g and any slicer start gcode.
For the bulges, you are not the first person to notice a difference in corner behaviour. We are beginning to investigate.

M208 X0:270 Y-7:285 Z0:250 S1Remove the S1 from that command. When using the two values for each axis range you need to leave off the S1. I wonder if this is causing it to incorrectly set the actual axis range. Please send M208 by itself to see what it currently things the axis range is.
Do you use bed.g for leveling? Can you post that as well?

X0 Y5 would be the front left corner of the bed normally. And based on your config and homing files that should be the case as well. Can you confirm that -x moves to the left, and -y moves to the front?
-
@phaedrux Yes, sure. -x moves to the left an -y moves to the front.
But at the moment, my primary issues are these bulges in every corner. The offset is something I can handle very easily. But these bulges are really annoying. I will try to downgrade to 3.4.0 tomorrow.
-
Sure. The bulges are a known issue though. I'm trying to understand why the prime line apparently moved all of a sudden.

If -x is left and -y is front, isn't the prime line printing at the front of the bed correct? Or do you mean something else by "printed in front of the bed?"
-
@phaedrux After homing X/Y I move the nozzle 0.1-0.2mm above the bed and print a "X,Y prime line" from 0,0 to to [middle of bed],0. By "printed in front of the bed" I mean, that the nozzle does not "print" on the bed but a few mm in front of it into the air.

Ok I understand now.

What position does it think it is after homing?
What position does it think it is when priming?
-
@phaedrux This is the Y position at Y0:
This is the Y position after G28 Y:
The position outside the bed is fine, because the limit switch is in this position.

G1 X0 Y-30 Z25
All I can see that may have an effect is that your move tries to move to Y-30 in absolute coordinates, but your M208 is limited to Y-7. I would suggest altering the moves to stay within the set M208 limits and see if that keeps your prime line on the bed.
-
I will try this out one day soon. More important for me are these bulges in the corners. I will now first switch back to version 3.4.0 (if this is possible).
-
Yes it is possible to switch between versions quite easily. All you need to do is upload the complete zip file to the system tab in DWC for the version you want. Please try 3.4 and 3.3 and see when the bulges appear for you. I'm guessing they will show up in 3.4.
-
@phaedrux At the moment I am unfortunately very confused. I flashed my Duet3Dv2 back to 3.3.0 but the bulges are still there. O.O
I can't remember that I ever saw this the last two years. This makes absolutely no sense. I may have changed something in config.g between 3.3.0 and 3.4.1 that would provoke this result. But I can't remember.
