Topic: SD improvements I'd like to see

I've only been coming to this forum for about 3 months so there's a lot of prior discussion I am not privy too, so forgive me if I'm covering beaten ground.

It would be nice if someone smarter than me could write mods that would:

1. Alert you with a beep from the PC when your bed and extruder are both up to temp (or temp plus X programmable minutes to soak and stabilize).

2. Another beep (or beep-beep-beep) to alert you when a print job is finished (because you know you'll be watching Golden Girls when it happens).

3. Maybe add a limit switch to the extruder where everyone else puts everything from cooling fans to dust pans. The switch could trip a beep-dammit to alert you when you have a runaway filament kink curling crap all over the place.

And here's some stuff I can do if I overcome inertia, but hey, if you wanna do it first, go for it.

1. Small reels to hold the sampler pack filaments.

2. A nozzle and maybe a piece of store bought 2" flex tubing to duct the heat from a hand help hair dryer onto the bed for aux heat up. I know Ian has done something along this line.

3. An hoe-shaped utensil to hold a single-edge razor blade for scraping prints off the glass bed. I keep breaking blades because I put too much lateral pull on the blade. Plus on larger parts, the itty bitty blade is hard to get between the part and that hot bed without burning my fingies.

And while we're at it, can someone come over and clean up my work space? My bench is really starting to look like hell.

Repetier-Host can do #2.  I wish it could do #1 as well.

You can use gcode m300 for beeps

Have it play you a tune if you'd like.

Re: SD improvements I'd like to see

I keep thinking there ought to be a way to combine the simulation of what the print is doing with a camera pointed at the actual print bed to warn you when the print bed no longer looks anything like the simulation :-).

I can almost imagine it might even be possible. Take the difference between the start and current images, then compare the differences to see if they are "the same" (modulo a lot of fancy calibration and fuzz factor no doubt).

But is there a way to make this get triggered by the temperatures reaching goal?

I mean, you don't need to use this to mark the end of print jobs since RH already has that functionality without having to do custom g-code, and I can't see how to use this to indicate something happening before you even started the job.

M109 S<temp> = ;wait for extruder temp to be reached

I use this in the "Custom G-code" section in Slic3r, which gets executed before the print starts.

Perhaps this also negates the need to use M300 for beep for just this purpose.

Excerpt:
M104 S173 ;set extruder temp and start heating
M109 S173 ;wait for extruder temp to be reached

Re: SD improvements I'd like to see

Hmm.. maybe my QU-BD makes me lazy... given its 5min heatup..

But I regularly will just tick 'Start job when slicing finished' - and as the Bed uses a 'Wait' command, it will heat the bed first, then the Extruder will start heating, giving the bed a nice 3 min or so Soak, then it just starts the print...  I'll wander back to the printer 5 minutes later to check it started ok... No alarms needed... smile

Re: SD improvements I'd like to see

Yeah, if I could just start the job when the bed's not at heat, I wouldn't need the beep.  The whole point is that that's when I need to clear the ooze, remove the lid, make sure everything's right, and then start the job.  But I suppose I could do that using a pause.  Even hit the sequential preheat:

turn on bed heating and wait for it to hit 80
turn on extruder heating
wait for the bed and heater to both reach target temperatures
beep
@pause
then do the actual job

Re: SD improvements I'd like to see

I like this thread. I am curious about what others want for thier SD.

As for starting, I usually heat up the nozzle to extrude a little before a job. Then I shut it off again and pull the excess off when it cools down. My start GCode in Slicer performs a home, then moves to the back right corner, and then begins heating up the extruder. This way when the extruder starts oozing, it only goes out .3mm to the bed and I get pretty good clean starts.

I plan to add the bed code to this as well with some extra wait time (I preffer a 7 minute soak on big prints).

Re: SD improvements I'd like to see

I keep trying to design a dual extruder setup where extruder #1 prints a cup and extruder #2fills it with hot cocoa or coffee if you like, the problem I run into is removing the cup since it will stay hot... I thought about putting a peltier on the bed to flash cool it and thereby releasing the cup... any ideas???

Re: SD improvements I'd like to see

Cocoa. Swiss Miss. Hot.

Re: SD improvements I'd like to see

Has anyone done anything along the lines of a small filter to put in front of the fans to keep dust, hair spray, etc. out? What kind of filter element would be slim enough and let air flow well but still skim out the larger birds?Medical gauze, folded over three or four layers? When I paint in my workshop with aerosols, I have a 28" shop fan with a like sized furnace filter bunged to the back. It gets full of aerosol fumes sooner than you'd think. That lets me breathe easier.

I have no idea if it will print but it is manifold.

better to just use a respirator for painting in an enclosed shop! haha

im sure you can probably whip something up with your printer to fit the need, but im curious which fans you need filtered on the printer? would be better to just run an enclosure if your not doing that yet. and take the glass bed out to hairspray it. haha. if your still running on the kapton, hairspray isn't really needed, just a quick acetone wipe before you start the job. so, not quite seeing the need for a filter =\.

I just tried sending "M300 S300 P1000" to my solidoodle which should make a 300hz tone for 1 second, but no sound. I assume that means there is no piezo speaker on the stock controller board?

You can download WAV files to make whatever noises. I think they need to be PCM though, like this:
