Adding the P parameter to M584 causes hidden axis not to home

[kazolar]

I defined my axis as follows
M584 Y0.5:0.0 U0.4:0.1 X0.2 V0.3 W2.2 A1.2 E1.0:1.1:2.0:2.1 Z3.2:3.1:4.2:4.1 B3.1 C4.2 D4.1 'A0.0 'B0.1
If I add P7 to hide the axis I don't want to see in the UI BCDab, then the homing for those axis doesn't work. I.e my homez.g script looks like this

M584 Z3.2 B3.1 C4.2 D4.1
G91
G1 Z6 B6 C6 D6 F450 H2
G1 Z-500 B-500 C-500 D-500 F450 H1
G1 Z5 B5 C5 D5 F450 H2
G1 Z-10 B-10 C-10 D-10 F100 H1
G1 Z0.2 B0.2 C0.2 D0.2
M584 Z3.2:3.1:4.2:4.1
M671 X708:708:-95:-95 Y615:0:0:615 S5
G92 Z-1.3 B-1.3 C-1.3 D-1.3
G90

if I had P7 in the initial M584 in config.g, then the homing doesn't move the BCD axis, if I don't use the hide parameter, everything homes properly.
I'm on latest 3.4 firmware

@kazolar you need to un-hide an axis in order to command it to move, for example to home it. You can un-hide it in the homing file before homing it and then hide it again at the end.

@dc42 I figured out I don't need to define individual axis anyway, just combine the end stops. No need for extra axis -- would be good if M119 would report the state of each end stop pin in the combined M574 definition. No good way to be sure you have the right end stop configured with the right stepper.

I did this
M584 Y0.5:0.0 U0.4:0.1 X0.2 V0.3 W2.2 A1.2 E1.0:1.1:2.0:2.1 Z3.2:3.1:4.2:4.1
M574 Y1 S1 P"io3.in+io1.in"
M574 U2 S1 P"io6.in+io4.in"
M574 X1 S1 P"io8.in"
M574 V2 S1 P"io2.in"
M574 W2 S1 P"2.io0.in"
M574 A1 S1 P"1.io0.in"
M574 Z1 S1 P"3.io0.in+3.io1.in+4.io5.in+4.io4.in"

that works fine and no extra axis definitions.
