ah okay good to hear, Btw my 0.4mm layer height 250mm circle produced no wobble, so I guess I'm good? Though I still need to figure out what the heck is going on with 0.3mm height underextruding...

@iamthebest22 Going to "close" this thread as what I'm doing now it's more tuning and tweaking rather than firmware installation. Thanks!

Sorry for the late delay, had to go to the dentist today for the usual stuff :P. Anyways, after forgetting to check all my drives are in the correct direction "coughextrudercough". I think I got it working. in Slic3r PE I turned the first layer temp off to 0 and this is my starting slicer gcode:
G28 ; home all axes
M104 S0 ; set nozzle to ensure 0 temp while auto bed leveling

G4 S300 ; Dwell for 300 seconds or 5 minutes
G28
G32 ; auto bed leveling
G1 Z5 F300 ; lift nozzle

M109 S210 ; wait for extruder temp
G1 Z0.3 X1 Y1 F6000 ; move to prime position
G1 E5 F60 ; prime 5mm of filament

printed a cube successfully
right now it does what it says, and then after 1st layer at 210, it goes to 207 for the other layers as specified. Woot!
I'm not finished yet though, because this machine is part of a longer process that I"m trying to fix and because it was getting z wobble at heights above 600mm ish, and I've changed the lead screws to 8mm instead of 12mm and put on thrust bearings. Not gonna talk about that here since it's been long enough, I will link to that thread though over here: https://forum.duet3d.com/topic/9053/very-very-weird-issue-looks-like-z-wobble-but/28

but thanks for all the help so far! Greatly appreciated!

Thanks for phaedrux, got firmware and some coding issues sorted out. I'm moving into tuning and tweaking now, so i'm posting here.

Need help setting up mesh grid etc for my Duet 3 mini 5+ on a Scara one arm printer. I feel like I might have something wrong with my settings.

Here's the original github for the X-scara printer: https://github.com/madl3x/x-scara/blob/master/firmware/CONFIGURE.md

Marlin config is here if some one can help: https://github.com/madl3x/x-scara/blob/master/firmware/Marlin-2.0.x/config/SCARA/X-SCARA/Configuration.h

Current settings:
M669 K4 P98.00 D98.00 A-105.5:106.5 B18.25:140 C-1:0:0 X100 Y-100 T0.5 S300

I feel like I may have set the distal arm endstop in the wrong location? Here is my setup in the homeing files:

G91 ; relative movement

G1 H2 X102 F2000 ; move proximal joint anticlockwise by 10 degrees
G1 H2 Y87.5 F2000 ; move distal joint anticlockwise by 10 degrees
G30 ; lower head, stop when probe triggered and set Z to trigger height
G90 ; back to absolute mode
G1 H2 X-60 Y60; move into printable area
G0 X0 Y0; move to zero point
G1 H2 Z30 ; move to 30mm so probing won't fail

Reason I'm asking is cause the B parameter is currently set to B18.25:140, and doesn't seem right, but when I do G1 H2 X0 Y0, it does go to the middle and lines up both arms.

Second is mesh grid. don't want to use the whole thing yet as I don't have th proper bed size,
M557 X33:80 Y15:195 S30 ; define mesh grid
but it's just goint too far to the left for G32. What should I set it too?

Third is that is there a command to test probe accuracy? Recall there was one awhile back, but forgot. Thanks!
