Y axis Hesitates on Homeall and Homey [SOLVED]

Silrocco

Hi all.

I decommissioned a delta and repurposed the Mini 5 on an old TAZ 4, which ran solid with the Maestro board, but I thought I'd give it an upgrade. I feel I'm 99% there, but the y axis has me frustrated.

When I command a "homeall", I notice an odd behavior with the y axis, it starts at the same time as x, but then the y stalls, then tries to move again with hesitation, only after the x has finished it's homing procedure. The y restarts slowly, then accelerates hitting the minimum limit hard (I e-stop it here).

I have tried several things, like reversing the direction of y and changing the endstop to high end, no success. Changed the drive assignment physically and in the config to match, same results. M119, show that the endstops are getting triggered when I actuate them by hand. Nonetheless, x and z axis home fine.

Than you!

@Silrocco I can't see any problems with the config, it is probably worth running M98 p"config.g" to check it for any errors. Could you also post your homing files?

@gloomyandy Hi.

I just solved the issue. I noticed in Object Model that the Y endstop was not showing "highEnd" and "type" it was for the X, but it was triggering, but not home as mentioned. So I switched over to another io, io5 to io2 and that solved it!

One more thing, I switched over to Normally Closed.
