[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

M98 P"/macros/poweron.g"

M913 X30

G1 H1 X-550 F20000 ; coarse home X
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.
