Without the current g-code it is impossible to analyse what exactly went wrong.
SV06 Plus firmware source code seems to be not available, however, in comparison to SV06 Marlin FW default settings it seems that your M203 / M205 settings for the extruder are definitely wrong.
SV06 default settings:
M203 E-axis max feedrate (mm/s): 30
M205 E max jerk (units/s): 10
You may want to try these settings & save after a successful test.
The G29 data is the measured 5x5 grid of your printbed. This is allright - besides from the fact that this indicates a huge maximum printbed difference of 0.5325 mm…

how do I translate what you said to g code? I’m not sure I get that immediacy.
do you mean
X500.00 Y500.00 Z10.00 E30
and
M205 iB20000.00 S0.00 T0.00 X5.00 Y5.00 Z0.40 E10
?

this is improved everything. Are these settings per device you think, or general? It is still not right but so much better.

Marlin g-code commands are documented here: [M203](https://marlinfw.org/docs/gcode/M203.html) / [M205](https://marlinfw.org/docs/gcode/M205.html).
You could either connect your SV06 plus via USB cable & enter g-code commands manually by using tools like [pronterface](https://all3dp.com/2/pronterface-how-to-download-install-and-set-it-up/)
or
edit a .gcode file with a simple text-editor by adding the g-code commands at the beginning of the file (ijaaz’ SV06+ settings should be fine)
`M203 X500.00 Y500.00 Z10.00 E50.00 ; set feedrate`
`M205 B20000.00 S0.00 T0.00 X5.00 Y5.00 Z0.40 E10.00 ; set max jerk`
Use [M500](https://marlinfw.org/docs/gcode/M500.html) to save.

Ok yeah, I was using pronterface. I will change the 30 to a 50 as that was the only difference.
but I think I see an issue, the fan is lower on the left side and hitting my model. I took the head apart and there is no adjustment for this The only fix I see is a bench grinder :x
EDIT: I put in the settings and took 1mm off the left side, and my issues are gone for the moment. Going to make a few more prints. I wonder why my unit came like that?
(sorry had to create a new account, my other one is strangely become locked?)

It seems to be too late, but if that issue comes up again you may want to prefer screwing out the nozzle of the heat block a bit & turning in the heat break on the other side instead of cutting off printer parts. Adjust the Z-offset aftwards.

I looked for something like that, can you find an image and point to the setting?

Interesting now, going back to PLA after making ABS work. I get this
Could either of those printer config adjustments do this? If I remember correctly this is under extrusion, the opposite I just had? I did not change any cura settings for PLA
retraction is .5 / 30mm so cant go much lower.

This is documented in the user manual - page 15…

I must have missed this memo, user manual? I got some cheap get ready pamphlet. Page 15 only talks about leveling. Thx I will look on line for this user manual.
Hmm, This is the same manual it came with… I have done my leveling many times, not sure how that relates to the setting for under extrusion?
On a promising note It may have been going from ABS to PLA, second print was much better. Maybe the nozzle was just a bit dirty.

> I looked for something like that, can you find an image and point to the setting?
The answer to that question is on page 15 of the user manual. The leveling setting is for the Z-offset I mentioned above.
Splitting your questions in separate threads might help to avoid such confusion.

Ok, no the nozzle height is good. It was the fan that was mounted on a 3 degree angle. Because of that the fan was very close to the part and clipping it. I could not fix the fan to be parallel with the head block. In the image you can see the fan is not set right.

My part fan is also at that same angle but it doesn’t drag on the parts.
