RepRapFirmware 3.0

Hi,
I´m just playing around with the new version.
One thing I stmbled across is M558
How do I set up a second probe?

I tried:
M558 K1 P5 C"!e0stop" H5 F120 T300
M585 Z100 F600 P1 S0

but I get the error:
"M558 invalid z probe index"

I can change K1 and P1 to 0 and it works, so there might be a problem with additional probes?

You are right, it wasn't working. Try the new binary that I've just put at https://www.dropbox.com/sh/3azy1njy3ayjsbp/AACquxr2m00eV568RZg5QG5wa?dl=0.

Thanks, that was fast
It is working now. Not exactly as expected, but I think it is my fault and I need to dive deeper into the configs.

How to setup probe on anycubic linear plus? In 2.xx probe worked fine. In 3.xx Probe is not even registered when connected.
Am I missing something?

which board and which probe?

Maestro was discussed mid may if you scroll up, not familar with what probe is original for anycubic, but hopefully the pin definition earlier in this thread will help.

@dc42 So what does have to change if z probe is connected to endstop before?

Use the C parameter ni the m558 command to specify that endstop pin. See https://duet3d.dozuki.com/Wiki/RepRapFirmware_3_overview#Section_M558.

Ok, I've updated to 3.0 to run my weird cnc contraption. I'm a bit stuck on how to set it up. I have two Y motors and endstops, z, x and e (which is actually a tangential cutter but rotates based on E moves). I have Y hooked up to the Z driver and mapped as M584 Y0 Z1 X2 E3. Does this make sense given I have two endstops and motors on that axis? Should I be defining the second y motor as its own axis to use an second endstop? What should my M574 look like?

As always, appreciate any help!

Seems off me? "Z driver" should be driver number 2, so you should probably have Y2 in there. Are you connecting both motors to the same driver output? If not you need something like Y2:1 or Y2 U1 (if the two Y motors are connected to the Y and Z drivers which ar drivers 1 and 2 respectively) ... or so i think at least.

If you clarify that bit I'm sure someone can help you with the M574

@bearer that's what I guess I'm trying to figure out. I currently have both Y motors hooked up to driver 0 (typically used for Z) so I can drive them off of the same driver without merging cables. This means I can't drive one without driving the other, which I guess means the best case scenario with two end stops is smashing one side into the endstop until the other catches up and hits the other endstop. Given I have an extra driver still, maybe I should drive each y motor off its own driver with it's own endstop, but still define both drivers as being the y axis? Not sure how to define the motors and end stops in either scenario on 3.0!

Which board are you using?

Then maybe you should wait for someone else to tell you that driver 0 is not the one labeled for Z as you seem to ignore me telling you that ... because you're not going to have much success until you do.

@bearer... I'm not disagreeing with you, I thought you were proposing a different way of achieving this setup, not trying to correct the way I currently have it setup, it wasn't particularly clear. "Should be driver 2" sounds like a suggestion, not a fact. One would think the drivers would be numbered sequentially from one side of the board to the other.

You would think that; but they are not. The order is 2 1 0 3 4.

@dc42 good to know. I think I'm going to abandon running them off one stepper anyway (unless there's a way to use two endstops that makes sense), so I'll have two drivers driving two motors on the y axis, each with an endstop. Let's say y driver and e1 driver. Does any sample g code exist for setting these up with their own end stops on 3.0 beta?

No, but it's fairly straightforward with RepRapFirmware 3. Use M584 in config.g (before any M350 or M906 commands) to define your Y motors:

M584 X0 Y1:4 Z2 E3

and use M574 to define the endstop switches:

M574 X1 S1 P"xstop" ; X min active high endstop switch
M574 Y1 S1 P"ystop,e1stop" ; Y min active high endstop switches
M574 Z1 S1 P"zstop" ; Z min active high endstop switch

Omit the M574 Z command if you use a Z probe to home Z.

@dc42 thanks! While I've got you. Let's say I do want to use the z driver for both Y motors, obviously I could only move them both or neither, but could I configure it with two end stops such that it isn't home until they're both pressed?

Wire switches in series or parallel depending on normally closed or normally open; but the first motor won't stop until both swtiches are active so you will have collisions.
