i am using slic3r 0.7.1 setting are these Yes ,filament diameter is 1.75 and my nozzle size 0.5by alfadex - General
I am trying to get my pursa mendel 2 to work properly .What problems do you see here and HOW can i fix problems please? I am new and i cannot understand whats wrong. I have measure the length of the filament correctly, i mean when i extrude 40mm of filament i measure it and it is 40 mm. i am using pronterface with default setting youtubeby alfadex - General
Yes you are right! I was using a usb to serial with a cp2102 but it was very unstable . I am using now a ftdi ft 232 with auto reset function and connection is ok !by alfadex - Firmware - experimental, borrowed, and future
Hello I am using teacup and when i am trying to print something i am getting these and then everything stops, what is happening?

i see what is happening when a lower resistance is placed there, thank you And one of these people that is confusing of making that table is me, i have read many times about that table,byt i cannot understand how to make that. But as Andrew said ,because bed temperature is not high enough as extruder ,wrong will be small enoughby alfadex - Controllers
yes yes i see, i really appreciate your patience ,if i need something else i'll be backby alfadex - Controllers
ok tnx Andrew ,i think now everything is working ok ,line 305 was wrong ,now it is correct. And for the bed, do you thing it would be better to change RT1 to 4.7 K ?by alfadex - Controllers
Andrew, i notice here at the board that RT2 refers to the extruder temperature ,so I change RT2 to 4.7 K. But now , bed temperature is about 10 degrees more than normal and extruder temperature is 16383 .by alfadex - Controllers
Ah i see, so i am changing now RT1 to 4.7K . I place comma on line 151 and now it says something at line 214 I place a comma at line 214 instead of ( ; ) and now saysby alfadex - Controllers
thanks, Andrew my extruder thermistor is 100K I place this file you upload but says thisby alfadex - Controllers
Could somebody make the table for the extruder , because i can not understand how to do this table please. My extruder is this and the thermistor is this EPCOS 100K Thermistor B57560G104Fby alfadex - Controllers
Αυτο το rοstock είναι όλα τα λεφτά! τρομερό μηχάνημα ,αυτό είναι να το χαζέυεις με τις ώρες.Στο τεμαχιστή θα του βάζεις διαφορα πλαστικά και σακούλες με μετά θα τα ρίχνεις στον extruder και θα τα κάνεις filament?? Δε πρέπει να έχει καποια συγκεκριμένα χαρακτηστικά το f;ilament? Καθε φορα θα σου βγαίνει με διαφορετική πυκνότητα, ή δε θα έχει αντοχή, η θα βγει με φουσκάλες π.χ και κάτι τελευταίο,by alfadex - Greek RepRap User Group, ελληνική ομάδα χρηστών
Μπραβο φίλε μου συνχαρητηρια. Θα ήθελα να σε ρωτησω ποιος είναι ο λόγος που έφτιαξες αυτόν και τι παραπνω έχει απο το mendel 2 εκτός αυτών που έχεις ήδη γράψει. Επίσης εαν αντιμετώπισες κάποια προβλήαμτα τα οποία λύθηκαν με τον Prusa Air 2 XL.by alfadex - Greek RepRap User Group, ελληνική ομάδα χρηστών
φίλε μου όλος τυχαίως υπάρχει το μοτερ απο υαλοκαθαριστήρα. Απο toyta corolla κιολας! Αλλα δεν έχω αρχισει ακόμα να μαζευω τα υλικά ,γιατί δε το εχω κανει ακομα να δουλέψει. Τελικα, για να μη χάνω άλλο χρόνο στις δοκιμες (μιας και δεν έχω χρόνο) το παράγγειλα έτοιμο αυτό και αν δω οτι εκτυπώνει σωστά , το φτιάχνω κατευθείαν!by alfadex - Greek RepRap User Group, ελληνική ομάδα χρηστών
μπαααα δεν αποθαρίνομαι, θα το φτιαξω δεν υπάρχει περιπτωση,δεν υπάρχουν λεφτά φίλε μου δυστηχώς αλλιώς θα τα έπαιρνα σχεδόν όλα έτοιμα. Πλακέτα έχω φτιαξει την Gen7. Τελικά, κατέληξα να φτιαξω αυτό .Πρεπει να βρω τεφλον καλο, διοτι αυτό που πήρα μαλλον ήταν έρταλον και δεν άντεχει πολύ στη θερμοκρασία. Επισης , με το που τλειεώσω με τη κεφαλή και δω οτι δουλεέυουν όλα ,ξεκιναω τη κατασκευή σοby alfadex - Greek RepRap User Group, ελληνική ομάδα χρηστών
Τι να πω! είσαι πολύ μπροστά!! Το πλαστκό που λιώνεις για να σχηματιστεί το filament τι υλικό είναι? Τελικα μου ήρθε το filament ,δοκιμασα να εκτυπωσω αλλα το wade's extruder που έχω φτιαξει δε δουλεέυι καλα. Το φτάνω στους 220 βαθμούς ,λιωνει,αλλα αν για 10 δευτερόλεπτα δε σπρώξει το μοτερ το filament ,τοτε μάλλον παγώνει και δε μπορεί το μοτέρ να σπρώξει το σπρώξει. Πιστεύω οτι θέλει παραπαρνωby alfadex - Greek RepRap User Group, ελληνική ομάδα χρηστών
γεια σου φ΄θυλε μου!!! εγω το έχω φτιαξει εδω και 3 μηνες και δεν έχω φιλαμεντ να το δοκιμασω, παραγγειλα απο το ιμπαι αλλά χάθηκε στη διαδρομή. έχεις να προτείνεις κάποιο καλο σαιτ για να αγορασω? Εχω το pursa mendel 2 Και θέλω pla μπλε 1,75 ή και μάυροby alfadex - Greek RepRap User Group, ελληνική ομάδα χρηστών
And finally i did it with a thermocouple.But hotend temperature is not controled by atmega. I made another ,seperate circuit with atmega8 which is controling the hotend I use another one mosfet IRFZ44 and i control the extuder totaly seperate! I know its not the best solution but temperature seems to be stable enough I am waiting now for the filament to print somethingby alfadex - Reprappers

I tried without pullup resistor but the same. I tried to measure CS to watch the pulses with osciloscope but when i connect it ,printer goes offline. I tried a second max6675 and doing exactly the same things! I am thinking to replace thermocouple with a thermistor to make things easier. My thermistor is this But datasheets says max temperature for thermistor is 125 degrees. Extruder reachby alfadex - Reprappers
ok i write this and connetct CS to pin 20 // enable TT_MAX6675 WRITE(DIO14, 0); // disable TT_MAX6675 WRITE(DIO14, 1); but i mean if i want to see the measurment to pronterface i have to set manualy CS from high to low. If i want to see a new measurment to pronterface i have to set again from high to low.I have to trigger every time from high to low to see the changes of the temperatue. If iby alfadex - Reprappers
ok i see,when CS is low it supposed to read the temperature of the maxx6675 and when CS is high serial aoutput is not enabled and so it does not work.Thats why i set pin 20, to control CS. But the problem is, that max6675 can read the temperature when i set from 5 volts to 0.I mean i have to trigger from 5volts to 0v so that read the new temperature. If i set CS always to 0v it does not change,iby alfadex - Reprappers
i see! i change it, to DIO14 and connect CS to pin 20 of atmega but this output is always 5V No matter if i set the temperature higher or lower than 16383by alfadex - Reprappers
ok look ,I edit line 128 and 145. and change 'SS' with 'DIO4,but DIO4 is PB4, the output of the mosfet extruder. I suppose i have to use an unsed output pin of the atmega because DIO4 is used,am I right? Which one should i use? I have found that is i change CS from high (5V) ,to low (0v) ,it reads the temperature right! If i want to use pin 20 of atmega (PD6) DIO? which nimber is?by alfadex - Reprappers
i hadn't read the datasheet for max6675 i connect everything , i use two theromocouple and the temperature it reads is 0 deegrees celciou P.s i have set CS to low,so that to enable serial outputby alfadex - Reprappers
ooh yes my mind stuck, i am testing nowby alfadex - Reprappers
what is ICSP connector? where is SS pin?by alfadex - Reprappers
i made again the circuit from the begging but i doesn't seems to work at all ! i am sure there is somethign that i have not understand. here is max6675 and here mosfet the circuit is this pin 6 is going to a resistor 10K and after to 5volt. What is JP2-2 and JP1-1 at this pin for?? pin 5 ,7, is going to TEMP-EXT at the board. I invert these but nothing hapens RT2 at GEN7 board is 10by alfadex - Reprappers
I will take photos and post here. I am using teacup. It was easier for me to place the thermocouple to the extruder because it is small ,thermistor is bigger enough and harder to stabilize it in a so small area . i will uplaod photo and if i don't find a solution, i 'll replace it with a thermistor.by alfadex - Reprappers
