Ok, disconnected cap and now it starts fine. Where should I place it to make everything work as expected? Directly to board power input terminals?

@dc42 just finished printing part. Rebooted board, dont have this message now, changed nothing.
Cap parallel to ssr control pads, I'd say connecting ps_on and 5V (my ssr doesnt work on 3.3v). Cap is huge, the only I had at hand - 2200uf 25v.

Hey, everyone.

Having strange issue and I need your advice to get direction.
My duet2 wifi powers from 24V psu. It also connected to ssr, controlling that psu via PS_ON pin. I've added capacitor on ssr control pins, to keep it closed to be able to reset board from DWC. Without cap, board releases ssr and everything turns off. It was working great. I have 2 Z motors on Z driver and Z probe.
Now, I took off Z probe, switched one Z motor to second driver (E1), added 2 optical endstops, changed config. It works as expected except for one thing - on initial launch, board doesnt fully load. Paneldue doesnt show any info like it haven't connected to board, no led flashed on wifi module. Only endstop's leds and voltage leds(all 3) are on. Pressing reset button on board makes it run correctly.
Also, message on paneldue after reset shows "VIN overvoltage 32.6V", but psu is still the same and shows 24.2V (DWC shows 24.3-24.4).
What can be the reason for this?
Config attached.

@phaedrux thanks, will try than

@phaedrux Actually, I dont know. I left it print overnight. Looking at where is skipped, it's about half time,~6hours. It was thin, but high model.
I had another long time print and skipping happened also. It actually looked like not just skipped step, but ~100mm momentary drift on X axis. it happened ~10hours after print start.
First time belts were tight, last time I've loosen them a bit.

@dc42 it doesnt have rear most wall, so duet isnt in closed box.

@jay_s_uk I have 5015 turbine blowing non-stop on radiators, glued on top of drivers

@jay_s_uk Blurolls 17HM19-2004S, came with my blv kit.

Hi, everyone
I have BLV cube with Duet 2 Wifi with rrf3.2, direct drive extruder, XY motors with radiators and coolers. Closed chamber(no wall near motors).
For some reasons on long prints I'm having steps skipping.
Motor current in config:
M906 X1600 Y1600 Z1600 E1600 I30
Print speed below 100.
Is my current too high?

@droftarts yes, already figured it out. Somehow missed it with Z home coords. Thanks anyway!
Yes, adj screws under bed, within printing limits.

Back to problem number one. Attached 2 pictures from DWC. One right after homing. Second after G30 command. You can see current coords are totally off with requested. Why?

Tried to run mesh compensation command. Set points via DWC, 30.30 is the first one. Starting calibration and head goes to -20:0 and, of course, misses bed, because it ends at 0:0. Why it runs to -20 if point coords set to 30? What am I missing?

I've raised current for Z axis p to 1000. Now I get only one warning message right on Z homing:
G28
Warning: motor phase A may be disconnected reported by driver(s) 2 4
Warning: motor phase B may be disconnected reported by driver(s) 4
Not 3 messages as before.
Moving bed 5mm while homing X Y doesnt make such messages.

But still got:
Warning: motor phase A may be disconnected reported by driver(s) 4
Warning: motor phase B may be disconnected reported by driver(s) 4
on Z movement 25mm, 5mm isok.

@Phaedrux Well, I assume motors wont rotate at all with messed up phase wiring. But they do work fine. Anyway, checked and wiring is correct.
I guess the problem is in settings. I'm totally new to RRP and Duet.
Current settings in config.g set to:

M906 X1600 Y1600 Z800 E1600 I30 

Assuming Z driver runs 2 motors, shouldn't I rise it to, maybe, same value as for XY?

Hello,

I'm building BLV cube on Duet 2 Wifi with rrp3.2 fw. I'm having few issues. Could you, please, suggest solution for them. First problem with manual bed leveling assistant. For some reason head travels totally off given coords. Zero coords are at front left. Homing at X min Y max.
My bed.g:

M561
G28 X Y 							  ; home 
G30 P0 X273 Y267 F1500 Z-99999      ; probe near an adjusting screw
G30 P1 X273 Y27 F1500 Z-99999
G30 P2 X33 Y27 F1500 Z-99999  
G30 P3 X33 Y267 F1500 Z-99999 S4 

My config.g includes:

M671 X33:273:273:33 Y267:267:27:27 P0.7

Sending G32 makes head move from home to ~ bed center, probe, than it goes far forward hitting limits.

Second question is:
Every time I home Z axis, I get "response too long" and these console messages:
3/19/2021, 10:41:58 AM
Warning: motor phase A may be disconnected reported by driver(s) 4
Warning: motor phase B may be disconnected reported by driver(s) 4
3/19/2021, 10:41:42 AM
Warning: motor phase A may be disconnected reported by driver(s) 4
Warning: motor phase B may be disconnected reported by driver(s) 4
3/19/2021, 10:41:38 AM
G28
Warning: motor phase A may be disconnected reported by driver(s) 2 4
Warning: motor phase B may be disconnected reported by driver(s) 4

Controlling Z axis manually same thing. But bed goes up/down just fine.
