My Second build (in progress)
-
Had to redesign some part , there was a few issue but i might have this thing going today ! Reprinted a few part overnights , and hopefully they fix the problem then I only need to fill up the water loop .

So now I need to calibrate things a bit more but I ended up doing it quick I wanted to test print lol
So far it seem the single 2020 were the z axis rail is, is not stiff enough and make the bed shake a bit , so I will need to had Some reinforcement to stiffen that . Need to work on my klicky dock as well . test printed with some old PLA that i had laying around ,
current setting in config is :
; Axes
M584 X0.0:0.1:0.2 Y0.4:0.5:0.3 Z1.1:1.2 ; set axis mapping
M350 X16 Y16 Z16 I1 ; configure microstepping with interpolation
M906 X2400 Y2400 Z1200 ; set axis driver currents
M92 X80 Y80 Z2560 ; configure steps per mm
M208 X10:205 Y-40:200 Z0:300 ; set minimum and maximum axis limits
M566 X900 Y900 Z100 ; set maximum instantaneous speed changes (mm/min)
M203 X90000 Y90000 Z500 ; set maximum speeds (mm/min)
M201 X20000 Y20000 Z500 ; set accelerations (mm/s^2)him curious to see how far i can push this machine once i fix the last few things
-
so a bit rough looking and lots of stringing from the old pla but not the worst benchy ive ever seen since it on an untuned machine , lots of stringing lol
-
Did some further tuning , extruder is nearly fully dial , skew compensation should be bang on , z axis step seem fine , just need to reinforce the z axis and we should all be set for more printing test .
-
Got the accelerometer working tonight and I it seem zvddd at 40-42hz was the flatest curve like.
Tomorrow I can hopefully fix the print bed shaking and keep going on those calibration and push the speed to see how far it can go
