COREXZ conversion tuning

danzaywer

Hi,
i just finished converting my AM8BLV to COREXZ (SWITCHWIRE adapt) and it seems to work fine.

However, I have some doubts about some conversions to do with the new kinematics:
with the Cartesian in the homing I raised the Z axis by 5mm still not homed to ensure that the noozle did not hit the plane

G1 H2 Z5

now this command move the z motor individually and then the carriage moves diagonally right-down. i solved by inserting

G1 H2 X5 Z-5

is it the right solution or is it possible to use something cleaner?
I encountered another problem with the bi MBL procedure, with the Cartesian probe the 4 corners of bed with the bltouch and firmware return to me the number of turns to be carried out on the screws to level the surface, now with the new kinematics I get the message that

M671 parameters do not apply to CoreXZ kinematics

and

Error: This kinematics does not support auto-calibration

in bed.g I have

	M401
	M671 X23.7:232.7:232.7:23.7 Y219:219:10:10 P0.35
	G30 P0 X23.7 Y219 Z-99999 		; probe near an adjusting screw
	G30 P1 X232.7 Y219 Z-99999 		; probe near an adjusting screw
	G30 P2 X232,7 Y10 Z-99999 		; probe near an adjusting screw
	G30 P3 X23.7 Y10 Z-99999 S4		; probe near an adjusting screw
	M400
	M402
	G1 X{var.xCenter-sensors.probes[0].offsets[0]} Y{var.yCenter-sensors.probes[0].offsets[1]}  F6000    
	G30

is not possible to use manual bed leveling?
in config.g I have

M584 X2 Y1 Z0 E3:3:3:3:3:3 U4 V8 W3 P5									; corexz
M669 K2 X1:0:1:0:0:0 Y0:1:0:0:0:0 Z1:0:-1:0:0:0

where U V and W are ERCF axes, is correct or I can simply put

M669 K2 X1:0:1 Y0:1:0 Z1:0:-1

instead ?
Thanks in advance
