Triangular wave and print area

ok i tried and this is the result on 4 points, but how can it help me to know this?

the last measurement is very odd.
did you copy the macro correctly? -
I created the macro M48.g in sys, then I created a macro where it indicates the coordinates and calls M48, but it doesn't work for me, instead of dwelling on a precise point it goes diagonally, I read that a G30 with parameter P wants the coordinates, so I created one with the coordinates and it works, I'll post the macro
-
-
G30 P9 X165 Y30 Z- 9999
there is a space to much after the Z-
-
ok, I'll call you hawkeye, correct and take the test again

ok that looks good.
now do the test again, grab the hotend carriage and turn on clockwise and anticlockwise between probes. dont force it but do it gently.
after that do it again trying to rotate it forwards and backwards.
-
in practice I take the trolley and manually try to move it and then I do the tests again, did I understand correctly?
-
@Leblond
yes. we are looking for backlash in the assembly. movement could cause the assembly to rotate and cause the result you are seeing. -

M906 X800 Y800 Z800 E800 I30 ; set motor currents (mA) and motor idle factor in per cent
there are default values from the configurator.
a quick google shows the motors seem to be 1,68 A motors
so you are running way to little current. try 1300
-
The motors are Quimat Nema 17 Stepper Motor 1.7 A 0.59 Nm 84 oz.in 47mm
-
@Leblond said in Triangular wave and print area:
1.7 A
so running them at 75% rounding to nearest 100 is 1300.
-
ok I took them to 1.3 and I'm doing the test again later

I'm retrying cold-meshing the plate to see if we've made any improvements
-
-
no improvement
-
it seems to be very consistent.
can you turn the glass 90 degrees?
