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...

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!

Any update to this amazing project? I've been wanting to build a Scara type printer for awhile now. had Nicolas' Project HELIOS and then his updated version but it went silent. I see you're using a dragon hotend too. Think your design (when it gets released) will work with a mosquito hotend + precision Piezo orion? Thanks!

Problem solved, well somewhat, but I'll take care of the rest of the issues now. Thanks again!

Aight trying M579 X1.03 Y1.03 then reporting back. can I put it anywhere in the config.g? or do I need to put it before a certain gcode?

Yes I did, but I'm just wondering which one of the two has less of an effect well three if I use M579 (which is similar to scaling in slicer) or play with rod length? I"m leaning towards slicer or M579 but would like to hear professionals advice.

Hi everyone, so my Tevo Little Monster has had a Duet Wifi on it, and it prints beautifully. The only problem is when it comes to print dimensionally accurate parts, I found that my LM prints always about 1.5% to 2% smaller on the X and Y axis (Z is very close to perfect). Both X and Y are the same issue. Now I have two options, I have read that I can play around with the rod length (my rod length on my LM are all within 0.1mm of each other and is 398.00mm through lots of triple checking and measure each rod) to scale X and Y, but is there a downside to that?

Right now I'm scaling objects that need to be dimensionally accurate to about 2% bigger than they are (so 102% in scaling), but should I play with rod length instead and not do that? Or stick this just scaling objects?

I've already, from before,check rod length of all 6, and also ensure the bearing distance between each is also within 0.1mm.

TLDR; should I play with rod length to scale X and Y, or just stick to increase scaling by 2% (102% in slicers)? Thank you very much!

oh my fault too, no problem, M92 it is, okay now we're all good, thank you very much everyone!

oh it's M350 for changing microstepping mid print? okay than, I think we'll all good now, thank you very much!

Got it, yeah that's what I'm confused about, whether it truncates or rounds it to a whole step and so it's really useless to use decimal values, maybe someone else can share that.

Yes that's what I've been doing, use M92 to enter that gcode, thanks, now hopefully someone can answer the question about the decimals esteps xD

@deckingman it works! Woohoo! Thanks deckingman! I just got hopefully one more question, I'm calibrating the pull one so that it "extrudes" a little more than the Zesty nimble (I have a mini buffer system like the Prusa MMU2 so it creates a loop), I'm calibrating esteps, does Duet accept decimal places for esteps? like for the 2nd one, I'm at 97.95 steps per mm but I'm wondering if that's actually accepting that as 97.95 or just 98 or 97. Thanks!

Update: another question came up xD. I just want to make sure I can change esteps in the middle of a print correct? I just have to type in M92 E2700:bbbb in the gcode console on the web control to change it mid print? That's what I've been doing but I wanna make sure that is the correct way to change esteps mid print. Thanks!

@deckingman wow that was fast, thank you very much once again for your patience, going to do it now and report back, thank you very much once again for your patience!
