I get a message saying -

Heater 0 fault - temperature rising much slower than expected, less than 1.6degrees per sec
I have a large heatbed, nothing wrong with thermistor, wiring or heating element

works perfectly! thank you

@droftarts

awesome! thank you
ill give it a go

Might be easier to show - this is my dual axis printer

this is a probe, in my e0stop

I want to home both my Z and U axis using the same probe

Evening all,

I have 2 independent Z Axis (Z and U)
U is in driver e0
z probe is in e0stop

I use below to z probe which works fine with my pressure pad switch, what would I need to do for my U axis to use the same pressure pad in e0stop?

M558 P5 C"!e0stop" H5 F300 T6000 ; set Z probe type to switch and the dive height + speeds
G31 P500 X0 Y0 Z4 ; set Z probe trigger value, offset and trigger height

Thanks

Evening all,

help please, I have a printer with 2 independent hotends, (X,Z) and (V,U)
How do I probe with my U axis?

I looked at G30 and it did not mention anything about multiple Zs configuration.

@dc42

now fixed! I didn't realise drive mapping didnt map end stops and V is E1
now working as intended

thank you

although the probe says triggered when not compressed and not triggered when I compress it, seems to be backwards

I can confirm V is in E0, compressing the switch also confirms by LED

Nothing in E1stop

I am currently using z probe for both Z and U

Afternoon all,

I have designed and built my own IDEX printer, it has 2 independent X and Z axis.
My V axis which is the second X axis refuses to home, limit switch is configured to NC, the Duet 2 wifi and Duex boards LED indicate when limit switches are compressed.

Any help would be greatly appreciated
