for your auto tune you need to add the setting to your config file for it to load
and if the bed is not pid you cant get it so work too...

i understand the part line by line but you can do a g01 in z and a e -5 in the same line, and you just get me to the point i will try this change all retraction same time as the move..... i dont know how repetier firmware work flawless and marlin too on my old crap ramp 1.4 board , and on the best one i just get farrr away of what i was still fighting the blob the retraction seam, patio slicer get better face quality but retraction problem is the same....

@dc42 i got a question did is better to enable the firmware retraction in the slicer ? if i print from sd i got worst peice, if i print from repetier i got better result but the retraction is not firmware enable

for the heater this part is easy:
For example, I’m very displeased that I have to wait first my heated bed to reach the heating temperature, later the extruder.

you need to cvhange in your software(slicer ) one command
M190: Wait for bed temperature to reach target temp
to M140: Set Bed Temperature (Fast)

easy enought but will start right away when the hotend get to temp

@mitko
completly in accord with you its the retraction speed the problem, not only that but.... i dont understand why duet need to retract and undo with out moving.... stop retrac move undo retract then go... that why you need fasters speed ans accelaration and jerk for the extruder....

your dimention are ok then and

@mitko
do you calibrate your extruder step /mm ? 10mm extrude 10 mm?
your square is square dimention are good?
cube 20x20x20 is realy 20x20x20?

@mitko said in RepRap firmware tuning:

.48

no the point was the speed u need to keep your step/mm setting
retraction 5 mm is a bowden setup i wanted you to just speed up de retraction and acceleration haha ur printing abs did you have the cooling fan on for your print?

im fighiting this from i buy the maestro, i resolv almost all problem but i cant i just cant get rid of this retraction un retraction problem, if i print from sd card the inboard software its worst, i did the repetier emulator setting in the config, and print from repetier directly but still have this

i buy this board to get the last hair from perfect print and its a lot worst yesterday i reinstall my old mks gen1.1 and all get back where it was, a 20$ board prit better than this one .

i didint let go the maestro i want to get this to work but... no sleep night start to get me hahahah

you need to get extruder speed to the fastest you can first:

M566 X1000.00 Y1000.00 Z300.00 E5000.00 ; Set maximum instantaneous speed changes (mm/min)
M203 X18000 Y18000 Z1000 E10000 ; Set maximum speeds (mm/min)
M201 X3500 Y3500 Z300 E7200 ; Set accelerations (mm/s^2)

try this and report

@dc42 ok i got time for test hahah seam a lot better with the "jerk" seti this way no skipping im pretty shure i didint see an under or over extrusion seam i print 3/4 roll of 20x20x20 cube for a little parameter hahahhahahah

tanks for all!!

@dc42 it work the same not needed

and i will let this here juste like that lolll
