Help tramming z axis with 4 motors and multiple endstop types

p8blr

I home z with a probe, however, I have optical endstops at the low-end of the 4 screws on my z-axis to assist with tramming if the screws get out of sync. This is necessary because the bed is too large and rigid to safely level the 4 screws if they are too far out of alignment. My issue is that my macro works, however, the printer will not home z with the probe after I run this. It is also preventing my brakes from turning back on after I run this. (Honestly, the brakes don't behave very well at all, but that's a different issue.) So I would like a more robust solution. Suggestions please?

@p8blr Please post your homeall.g and/or homez.g if the following doesn't work. Also, what firmware version?

In your config.g, you define the Z endstop as using a probe:

M574 Z1 S2  ; configure Z-probe endstop for low end on Z

If you're using a G1 H2 move to home Z in homeall.g/homez.g, when you redefine the Z endstop in your macro as:

M574 Z1 S1 P"0.io3.in+0.io4.in+0.io5.in+0.io6.in"

it then uses this for the G1 H2 move in homeall.g/homez.g.

Either:

Use G30 to home Z with the probe. You don't need M574 Z1 S2 in config.g, this can just set the other endstops. Or
At the end of the Z tramming macro, set the Z endstop back to M574 Z1 S2.

@droftarts I'm currently struggling to get my printer working in SBC mode again after running a firmware update. I appreciate your suggestions and I'll be sure try them as soon as I get back to an operational state. Thanks.

p8blr

@droftarts I was able to get my printer running again if I changed it to standalone mode, rather than SBC, and upgraded to 3.5.3-rc.1. Here's some new code that I tried, the idea is creating a new axis A will stop it from interfering with the z probe, but what I'm noticing is the brakes quit working after this is run. Thoughts?

@timschneider @chrishamm Is this issue here also related to the other brake issues we've been having? I'm running 3.5.3-rc.1 and still have the issue of the brakes not working after being re-mapped to different axes.

gloomyandy

@p8blr You still have the probe mapped as an endstop:

M574 Z1 S2                             ; configure Z-probe endstop for low end on Z

Do you actually need to do this? You do not need to define the probe as an endstop if you are using G30 to home/probe the bed. See Ian's post above, it may well be that this is causing the interference with the z probe you are seeing.

droftarts

@p8blr I don't see how remapping the Z axis would change the behaviour. A G1 Z# H1 move will use the defined endstop to home. A G30 command will use the probe. Can you post your homeall.g and/or homez.g?

The issue with the brakes not re-engaging should have been fixed, though it hasn't been closed, as is marked as 'requires testing': https://github.com/Duet3D/RepRapFirmware/issues/1023
It's mentioned as a bug fix in the 3.5.3-rc.1 release notes https://github.com/Duet3D/RepRapFirmware/wiki/Changelog-RRF-3.x-RC#reprapfirmware-353-rc1-changes-since-352

M17 did not energise the motor brake solenoid (issue 1023)

Are you saying there's also an issue with M18, that the brake doesn't come on when the drives are disabled? If you are sure it's not working for you, can you post to the Github issue?

Ian

dc42 created this issue in Duet3D/RepRapFirmware

closed M17 doesn't re-engage motor brake #1023

This all works and the brakes keep working. But if I unmap the brakes and re-map the brakes, or remap the drive that uses brakes to a different axis, the brakes... break. The only way to get them to work again is to reboot.

Also on the M569.7 command, if the S parameter is too high, it causes SPI issues in the DWC console.
