[3.3-rc1] homing causes controller reset

[Serbitar]

Simple test at the moment using 3.3-rc1. Printer was working under 3.3b3.

Power the controller and SBC up from the mains
Try to home X by either hitting the home X button in DWC or typing G28 X into the DWC command sender.

Board powers up but does not move any motors.

I have this homex.g

G1 X20      F20000      ; move away from the endstops
G1 H1 X-20 F1000   ; fine home X

@serbitar said in [3.3-rc1] homing causes controller reset:

reason: MemoryProtectionFault

I'm getting the same issue.
Does yours give this error after the connection is lost when trying to home?

Lost connection to Duet (Board is not available (no header))

[dc42]

@Serbitar and @tristanryerparke, thanks for the report. I have located the problem and I am preparing a fix.

[dc42]

@serbitar and @tristanryerparke please try the new 3.3RC1+1 firmware binary at https://www.dropbox.com/sh/dlb58vkmu1u4fkx/AAAelkXSfRKVwI6_yqRnhGHPa?dl=0 and let us know whether it resolves the problem.

[Serbitar]

@dc42 That's fixed it!

Thanks for turning the fix around so quickly

[tristanryerparke]

@dc42 You saved the day again david, back up and running no issues so far.
Thanks,
T

[Nuramori]

That fixed it for me as well.
