Hi,
I am building my own 3d printer and am using Marlin bugfix-2.0x.
XYZ axes move ok, both ways.
XYZ axes will all home ok.
I have installed an inductive probe for ABL (auto bed leveling) - works fine.
Have had to enable "safe bed leveling" as my L probe is off the bed on one side only (X home side).
It needs to have the X axis at anything above 30mm for the Z probe to be on the bed, so i have changed the following :
#if ENABLED(Z_SAFE_HOMING)
#define Z_SAFE_HOMING_X_POINT (X_MIN_POS)>= 30 // X point for Z homing when homing all axes (G28).
#define Z_SAFE_HOMING_Y_POINT (Y_MIN_POS>= 0) // Y point for Z homing when homing all axes (G28).
#endif
This seems to work, except it wants to go to X=31 in order to home the Z axis. Have i put the correct code in (X >= 30 did not compile)?
What i want is for the Z to home if X is 30 or greater, Y can be any value as the probe will be on the bed at all Y values.
The problem is, it homes the X axis at normal speed, it homes the Y axis at normal speed, then it needs to move (in this case, X only) X to 30 (31) before homing Z on the bed.
It does move X, except it is very slow, and it sounds like it is doing small steps with a gap between each one (not continuous).
It will eventually achieve the X position, and Z homes at the normal speed.
If i leave the safe homing to (X bed size)/2 and (Y bed size)/2, then it moves the y axis, first in the same slow discontinuous fashion, then does X slowly - this drove me initally to reduce the travel required.
It does this same slow discontinuous stepping when actually doing the bed leveling routine, in between the sample points.
At all other times the motors for all axes work without problems.
All operations are done from the 3d printer control panel.
So, i am guessing there is one s/w setting causing the slow discontinuous speed for both operations ?
#define XY_PROBE_SPEED 50 - has been set.
Many thanks
