We recently updated the firmware on our Taz Pros, and the initial leveling sequence is a bit different now. Once the print head hits all the corner washers, it moves to the lower left corner of the plate until it gets up to temperature. Once it hits the target temperature, it squirts out a little blob of filament in the corner, which it didn’t used to do.
I assume that there’s a reason for this little bit of extrusion, but the problem is that this little blob often doesn’t stick to the plate and stay in the corner, it sticks to the nozzle or gets dragged along, and then creates an issue when the nozzle starts printing the inital layer.
Is there any thing I can do to either a) have the nozzle a bit lower when it prints the test blob so that it squishes it into the plate and makes the blob stay where it should; or b) change the settings so it doesn’t print this test blob?
Thanks,
Phil
This sequence would be part of the startup GCODE changed in updated slicer software, not part of the firmware.
What version of CuraLE are you running?

Ah, that makes sense. We’re using Cura LE 4.13.10, I believe the most recent release. We also recently changed machines that we slice on, and now it’s a windows laptop so we reinstalled Cura. Does changing the CGODE in the machine settings section in Cura authomatically apply that code to all newly sliced items?
Thanks.
Yes. The machine settings contain the startup, which is independent of the code generated by different profiles, so you don’t need to change startup whenever you change filament or speed/quality profiles.
Got it. Do you think that test blob is important? Would you try to change the gcode so it lowers the z closer to the plate to try to make it stick more reliably, or just remove the code for that blob?
If you’re doing a skirt in the GCODE, remove the blob.
