@en_passant said in Print head crashing into X/Y axis!:

it has M667 S1 set, so that's now commented out and I have M669 K1 in it's place.

Currently either will work, but M667 K1 is the correct way going forward.

Cool, thanks. I'll keep that from now on.

Just now managed to get it running and I'm very pleased!

@dc42 said in Print head crashing into X/Y axis!:

As @Phaedrux says, you will need to reverse one of the motor directions. From memory, I think it is the Y motor, and you need to change S0 to S1 or vice versa in the M569 P1 command in config.g.

Indeed it was. Presumably, the more au fait around here could write it out in 10 minutes but getting used to the code is time consuming wrapping my head around it.

@carfnann said in Fan short circuit, how to fix?:

I was able to find one supplier of these mini fuse 1A on amazon.fr
order them a box, then they cancel my order because out of stock...

no way to find some in France...

and today I've received my panel duet 7 and cannot play with it

I purchased 10 from the link @dc42 supplied. I've checked and it shows they will post to outside UK but I don't know costs, see here:

I've also just fitted a 2A from this, until the 1A fuses arrive from the link above. May be worth looking at if they deliver to France or if there's an equivalent, if delivery from the other link may take some time.

I was slightly more concerned as to why the fuse blew but I've just fitted my E3D V6 fan and when I powered up it spun away so I'll switch that engineering side of my brain off for now.....

HTH,

@dc42

Google didn't seem to pick them up for me but I've just picked them up now, thanks.

@Karma

Thanks for the help! Appreciated!

@Karma

Ahh, you're in the US. I did also find them - but I'm in the UK... which seems to have a distinct lack of 1A ATM mini blade fuses!

Might have to go with China....

e_p

@Karma

Please, yeah. (Not sure it's against forum rules, but don't think so...)

I've found 1 - but it's on eBay from China and going to take a month to arrive!

@en_passant said in Fan short circuit, how to fix?:

I wasn't playing with it and short it

if the short circuit curren't didn't pass through the mosfet then its probably okay, the other way around the mosfet usally fail before the fuse.

sharing OPs general location might be a good idea, myself and others may also have a fuse to spare nearby.

If you should happen to find another, I know someone in London who'd be grateful!

e_p

feeling @carfnann's pain as I'm trying to find the same fuse! Easy to finds 3A+ (even 2A on Amazon), but 1A not so.

@bearer said:

while its probably not supported both the fan mosfet and the traces* on the board can deal with 3A, so in theory the the fuse (or the fan wiring) should fail before the board if you were to use a 3A fuse while you wait, and a fault develops. On the other hand odds are the mosfet for the fan in question is also blown, so I'd probably use a 3A just to test even if not for prints.

Hoping mine will just be the fuse and not the mosfet as I wasn't playing with it and short it (what's more, since I've had the Duet wifi... it's never had a fan plugged into it! )
Where about is that guy out of interest?

e_p

Didn't realise there was a fuse for the fans... and even with the diagram took a while to find it!

Fuse it is.

Hello all,

I have just connected my e3d v6 fan to my duet wifi "always on" fan connector but the fan isn't kicking to life. I've disconnected and checked continuity of the wires to the fan which is good. I've tried moving from always on fan 1 to always on fan 2 (not identified as such but from closest to the main VIN to the next one along) but still the same. I have changed the fan as I had another laying around - still no good. Disconnected the fan and checked for voltage - nothing coming through, despite getting 0.02 continuity.

I have RRF 3.1.1 - do I need to configure the always on fans so they go live (as I've read the dozuki but it only states fan0,1,2 which I presume are the PWM fans?)

If so, how do I configure them in my config.g?

*e_p

@bot said in Unsure with Duet (RRF3) & Simplify3D:

For M116 try putting just the tool number with P0 instead of the heater number.

Maybe also try setting temps with G10 and then waiting with M116 instead of both M109 and waiting.

Other than that, I can't spot anything that seems amiss.

Thanks @bot. I appreciate you taking the time to read my config & scripts.

I just tried:

T0				; select tool 0 (hot-end)
M190 S[bed0_temperature]	; set bed temperature
M109 S[extruder0_temperature]	; set hot-end temp
M116 P0 S2			; wait: hot-end = [extruder0_temperature] +/- 2C

to no avail. It doesn't even change the active temperature on DWC (though my bed is changing to 55 as I set it to in s3d).

I suspect M109 S[extruder0_temperature] isn't correlating with s3d.

Not sure how to implement G10 - as it mentions that (and appears so) that s3d uses M109?
