Errors Compiling

Hi! did you compile the code without errors? because i´ve installed all the libraries and hace errors with the filter,

yes of course, I have two working machines. can you show me compilation error log?

[boomsya]

here is copy of Thermistor library: ThermistorLibrary.zip

You can try to replace files with my variant (folder C:\Users\<USERNAME>\Documents\Arduino\libraries\ThermistorLibrary)

[Gokuh1980]

oh! Nice! It compiles OK now!!! THANK YOU VERY MUCH!!!!

i have one question, didn´t read all the code, but, do you close loop on motor speed? because when at a fixed speed if you wind up more than one layer the angular velocity will increase making the filament thinner, what do you think? maybe an encoder after the filament is cooler could help?

[boomsya]

some versions before I maked this algorhytm. Here is 2-3 lines of code. In my case every 6 meters I have real +3% of speedup of winding because every layer of filament is +1.75mm of radius. But new features will goes to 104% of code space :( and I have removed this feature. And second - after first layer filament try to wind in center :) and I have one perfect layer and other length is like mountain (cant find right word of this, sorry). But I have measure thickness of filament - all ok, because I wind on slow speed and I have some reserve for speedup. So it is not problem as you and me think :)

I have use 5 (34 gramm filament) or 6 (43 gramm filament) litres bottles. Is variable from 10 to 15 metres of filament. You need to play with steps_in_cm constant for right calculate of length.

Many peoples in my house leave bottles to me and bottles have the thinkess from 0.1mm to 0.25mm. Very good when is .25 because I have more filament in gramms :)

And last - you need to change stripe width according to bottle plastic thinkess!!! I can make some photos of my bottle cutter and how I regulate width of stripes according to thinkess if you need.

[boomsya]

If you interrested, maybe you want to view my new repository (DIY filament dryer) https://github.com/boomsya/filament-dryer

[Gokuh1980]

Excelent, i understand your explanation, i´ve just started the construction of this pultruder. Could you explain to me the steps_in_cm constant?

ifndef MACHINE2

define steps_in_cm 1357

endif

ifdef MACHINE2

define steps_in_cm 629

endif

you only use this to show % in advance of the process or does other function?

i would love to see photos of your cutter. i understand the issue with strip witdh vs wide, i´ve seen one calculator online.

some filament pultruders put the cutter right in front of the heater, what do you think of this?

btw nice filament dryer!!!

[boomsya]

I have two filament maker machines. Cogs on drives is different. So winded length of filament is different (I counting motor steps) and if I uncomment #define MACHINE2 then compiler works with #ifdef MACHINE2 source code. In other case compiler works with #ifndef MACHINE2 source code. When I make some changes I have upload new firmware into two Arduinos with different "configs". This affects only to calculating length of maked filament.

I never use calculator because (easy to talk on native language, and some hard on english :) ) you have some diameter of hole in extruder, it is not 1.75mm and can be 1.8mm and calculating will be wrong. Best solution is when you have some thinkess (example is 0.15mm) of bottle and makes (for example) width of stripe 10mm and when you wind filament you can see what stripe fold in O-ring tube (real O) - this is good. But if you make 9mm width - you have almost O-ring tube (for example 270 degrees only), and if you make 12mm width - this stripe stucks in extruder or you need more slow down winding or increase temperature for make stripe more elastic. I am always use 222C. But if I see what the filament is stretched very hard (beetwen babine and extruder) - I slowdown speed or increase temperature to 232-236C. For understanding this - I play on stretched filament like on guitar :) if I hear song :) so I need to make life easier to motor :) On ptohos you will se how I regulate width.

"some filament pultruders put the cutter right in front of the heater, what do you think of this?" - If you mean about cutter so I have seen this but you never can cut bottle automatically without problems. So I make strips and wind to DIY babines (from plastic babines but make only 15mm of width) and this babine put before heater.

[boomsya]

final version of machine: on first photo you can see paper box - this is for saving temperature near heater (I dont want to heat my apartment :) in summer hell) and you can see thin babines with stripe winded on it - very useful

[Gokuh1980]

Ohhh wowwww!!! U left me speechless!!! Thank you so much for your explanations! I'll take every recomendation you made! In a couple of months when the heatblock, heater and thermistor arrives i will show you my results! (They are really expensive in my country... Argentina).

[Gokuh1980]

Hello, how are you? I was looking at the electronic circuit and I saw the potentiometer for motor speed regulation, which is connected to pin A1, however in the program I don't see it. Isn't it more necessary? If I see in the program that the speed is controlled by the encoder, am I right?

[boomsya]

yes, you right. Potentiometer I removed in some version of fimware ago because is make some noise in resistance. I mean potentiometer is not very good quality and resistance changing continiolusly +-100 Ohm. So speed of motor changing too. So I was rewrite code to change speed with encoder (and hole from potentiometer I was hide with Noctua logo metal plate). Think I need to update scheme. Thanks.

[boomsya]

and I forget - as you see - stripe from babine goes under panel (with 4 bolts) and after it he goes to heater. So, inside this panel I have sensor of "end of filament". It is like button (from old DVD), like this:
