@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!

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?

@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?

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

@en_passant, as a side note, S3D is a stale product.

Once you will have this working, you may want to consider one of the free slicers such as PrusaSlicer or Cura which are actively maintained.

Yeah... I was on simplify3d's forums trying to find an answer for this and seen a lot of very unhappy customers! I got an email about a year ago saying there was version 5 being introduced at the end of 2019, that then moved to the beginning of 2020...

But, it's what I've got and would rather get the printer set up using something at least somewhat familiar before venturing off the beaten track...

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

What version of simplify3d are you using?

Once you indicate that the heater controller is a heated bed, it shouldn't prevent you from choosing T0 for bed.

It seems like a starting script or something is selecting T1 for your print. Are you trying to print with a second extruder? It should choose T0 for the print if not.

I'm on 4.1.2. I quit and restarted it and I can now select primary extruder = T0 AND heated bed = T0.

My config now has:

M563 P0 D0 H1 S"Nozzle"			   			; tool 0 [hot end] define
G10 P0 S0 R0		        				; tool 0 [hot end] operating & standby temps

G92 E0				; set extruder position to 0

but when I ran a test cube generated with those I get:

24/05/2020, 21:52:59	Warning: Tool 0 was not driven because its heater temperatures were not high enough or it has a heater fault

The heated bed changed over from 50 to 55 just like I want but the hot-end is saying it's not hot enough.

I now think this may be because (as I noticed when I heat the hot-end manually) I cannot extrude until 160. The reason I have 140 is because I have precision piezo and it's advised (and I did notice when I tested) it gets a bit spurious above that when doing G30.

I did also have:

T0				; select tool 0 (hot-end)
M190 S[bed0_temperature]	; set bed temperature
M109 S[extruder0_temperature]	; set hot-end temp
M116 H1 S2			; wait: hot-end = [extruder0_temperature] +/- 2C

but it seems to ignore the wait command?

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

s3d uses

M140 S100
M190 S100

to set bed temperature

T0/1/2/3... irrelevant

only thing important is to have M140 H0

Thanks @arhi. And the hot-end? It doesn't seem to pick up my M109 S[extruder0_temperature]...?

e_p

Thanks @bot - appreciated.

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

@en_passant

My hotends are T0 and T1. There seems to be no conflict with the bed being "T" anything. I think this is just S3D being lazy and not making things make sense.

I just changed my config M563 to P1for hot-end. Then changed the starting (and ending) scripts to use T1 opposed to T0.

I got this:

24/05/2020, 21:26:18	Warning: Tool 1 was not driven because its heater temperatures were not high 
enough or it has a heater fault
24/05/2020, 21:26:21	Error: Attempting to extrude with no tool selected.

My hot-end temp on DWC didn't move from 140 it was at for the part prior in the script... but the bed did move to 55 which is what I set it to for testing so may be making slight progress!

So, in simplify3d you have heated bed = T0 and also have hot-ends as T0 and T1?

I'll move my tools configs back to T0 for hot-end in simplify3d, config and scripts...

Edit: can't change simplify3d to T0 (because heated bed currently T0)

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

Is the output from simplify3d interpreted with my M190 S[bed2_temperature] and M109 S[extruder0_temperature] - so the printer will see the output from simplify3d and use it?

Yes?

I'm not sure I understand the problem. Is your printer not heating?

What does simplify actually produce for gcode? Those commands should evaluate to actual usable gcode commands and the firmware should respond to them.

What isn't working?

I tried running a print of a test cube but I'm getting heater faults:

Warning: Tool 0 was not driven because its heater temperatures were not high enough or it has a heater fault

I have tried changing my starting script but I'm unsure what I should put in M190 and M109 so it correlates with simplify3d.

I have:

T0				; select tool 0 (hot-end)
M190 S[bed0_temperature]	; set bed temperature & wait

M109 S[extruder0_temperature]	; set hot-end temp

; change M109 to M104 T0 S[extruder0_temperature]?

M116 H1 S2			; wait: hot-end = S[extruder0_temperature] +/- 2C

G1 E10 F500			; extrude 10mm @ 500mm/min (prime)
G1 X5 F10000			; x 5mm y 0mm [absolute] @ 10000mm/min (wipe start position: x 5 y 0)
G1 Z0.10 F1000			; z 0.10mm [absolute] @ 1000mm/min (bed up to begin wipe)
G1 X177.5 E5 F15000		; x 177.5mm [absolute] & extrude 5mm @ 15000mm/min (max) whilst z = 0.10mm [absolute] (nozzle wipe: extruding while moving)
G92 E0				; set extruder position to 0

I changed the script above to M190 S[bed0_temperature] because my config has:

M140 H0				; bed heater #0 = heater #0 [m950 h0] (implied due to no p (bed heater index) parameter invoked)

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

In S3D my heated bed is listed as T0.

In your start script, it should say bed0 temperature I believe, to match T0, but I'm unsure if the T0 actually applies to the bed.

Regardless, FYI, my setup has bed as T0 and start script uses bed0_temperaure.

Thanks. Is your hot-end set up as T1? ...T2 etc? Do you have T0 setup as your bed and hot-end setup as T1 in config.g?

Save the generate gcode from S3D to a file, open the file with a text editor, and search for M190. This is what the duet will see.

(it's S3D job to replace those variables with the actual values before writing the .gcode file)

Thanks! I'll try having a look now!

Thanks all!

Does anyone with simplify3d have any ideas? How do you have simplify3d setup for heated bed?

My only options in simplify3d are:

Do I need to set G10 P1 in config.g > tools?

Is the output from simplify3d interpreted with my M190 S[bed2_temperature] and M109 S[extruder0_temperature] - so the printer will see the output from simplify3d and use it?

Apologies: post was longer than 10000 characters so reeling to continue questions.

The M190 S[bed2_temperature] and M109 S[extruder0_temperature] within the starting script are what's confusing me (I have bed heater defined in my config, M140 H0)

Within simplify3d my "primary extruder" has temperature identifier "T0" which I think seems OK. But it also has "heated bed temperature" identifier is "T2" and when I try to change it or define it, I only have options of T0 through T5... so, it is making me select a tool?

This was configured a long long time ago (I upgraded from RRF1.something to RRF2 and config/simplify3d had been set before I upgraded to RRF2).

Not sure what I'm missing here so that simplify3d can control my bed heater (as per my M140 H0) and hot-end? (I think my hot-end is OK as I have M563 P0 D0 H1 S"Nozzle" within "tools" in my config?)

Appreciate any and all help so I can finally get this thing running!

Hello all,

I've just got my printer switched over to RRF3.1.0 (in the hope of finally getting it going!)

Not sure if this will be good enough for you, as it's not "automated" but I made 2 macro's which I run to get z-offset easily (run from dwc console):

z height macro 1:

M561 ; transform identity: cancels previous bed-plane (mesh)
G21 ; work in mm
G92 E0 ; reset extruder count
M220 S100 ; reset speed multiplier

M104 S160 ; set hot-end to 120C & do not wait
M190 S50 ; set bed temp to 50C & wait
M109 S140 ; set hot-end to 140C & wait

M109 S200 ; set hot-end to 200C & wait

G91 ; relative co-ords (from last position not origin)
G1 Z5 F500 H1 ; z 5mm @ 500mm/min (ensure it's below probe trigger height)

M118 S"mesh compensation has been cancelled. re-run mesh compensation macro after updating config.g g31 z value with average of values calculated above (sum all, divide by 10)."

Adjust values per your printers speed values etc.

Edit: I use 0.05mm on a feeler gauge rather then the industry standard piece of paper.

That is informational warning to tell you what the heater model expects the max temp to reach in an uncontrolled on state. It's up to you to take that information and mitigate the issue accordingly. Thermal cutouts, lower powered heaters, smoke alarm, firm extinguisher, etc. That's all up to you.

Cool, I'll look into that. Thanks.

My main issue is still wrapping my head around the GPIO format - how do I know the names of the pins assigned for my Duet WiFi? It used to just be a connector specifically for a, b, c. How can I know that I have the correct thing connected to the correct GPIO pins and assigned as such?

@Phaedrux said in RRF 3.1.0 from 2.03:

If you send M98 Pconfig.g in the console it will execute the config and give any error messages encountered. That can help show issues before getting deep into it.

Just ran it and everything seems OK, except for:

18/05/2020, 21:14:50 M98 Pconfig.g
Warning: Heater 0 appears to be over-powered. If left on at full power, its temperature is predicted to reach 203C
Warning: Heater 1 appears to be over-powered. If left on at full power, its temperature is predicted to reach 848C

I've never had my printer not say the heaters are over-powered. Not sure if there is something I can do to remedy this.
