ok, problem solved... the new host software can't work if i choose only one extruder... who would know that?!by Jorge Nunes - RepRap Host
I was trying to make a gcode, and i have this error appearing whenever i press the print button: "array index out of bounds exception"! what can i do about this?!?!?!?!?! help please!!by Jorge Nunes - RepRap Host
the solution was so simple... it almost made me think i didn't really had a problem... I took a closer look to the settings of the host software, and just had to put no in the fived setting... as he was working like i was using the 5d firmware, he didn't sent the right signal to sanguino... after that, simply worked perfectly! I mean, almost... the heat dissipating plates are too small... i haveby Jorge Nunes - RepRap Host
problem solved. Thanks for the help! now i just have to figure out why does the host software stops responding sometimes...by Jorge Nunes - RepRap Host
yeap... the test works fine... One thing i didn't mention, which may be the problem: I've tried to use the 5d code (1.6 version), but when i choose the thermistor, it displays an error message. So, as i was using gen 2 electronics, i've installed the sanguino 1.4 version... in the code, i can't really understand if it uses the stepper motor for the extruder, but it seemed so... I'll try to finby Jorge Nunes - RepRap Host
ok, i did found out why my y axis wasn't moving... one of the pits was cutted in the stepper controler. however, the extruder stepper still doesn't move.... and the board is fine, as i have also connected it to the x controler wires and it moves... so, in terms of hardware, the only thing left to do is check if the plug which goes from the sanguino to the stepper is ok... if it is ok, then i mayby Jorge Nunes - RepRap Host
When i first installed the software, every stepper started pulsating after a while... until i find out in the code that for the 1.2 controler i had to invert the sign for enable and disable... after doing that, they all stopped pulsating. so, i think that the problem i have with the extruder is the same, the enable is on, and for some reason, the motor starts pulsating. perhaps its a "bug" of theby Jorge Nunes - RepRap Host
I connect the extruder stepper plug to the x, y or Z and it works. I've already tested the extruder in that way... the stepper controler also works if i connect the x y or z plug... The problem, i believe, is in the firmware... the stepper goes back and forth, like you say. It doesn't change wether i turn the extruder on or off. by what i've measured, the enable pin is allways with 10V, I belieby Jorge Nunes - RepRap Host
Hi! I'm assembling a reprap but I have a problem.... I'm using a sanguino with a breakout shield, temperature sensor v2.0 with a 100k termistor, pwm driver v1.1, 4 stepper motor driver v1.2, and the latest firmware (not 5d). the extruder is stepper driven. when i connect everything, the xyz motors work, but the extruder doesn't. even if everything is off, it starts "pulsing" after a few secondby Jorge Nunes - RepRap Host
Hi! after the first attempt not so good as i wanted to, I've decided to do another attempt.... However, there is one thing i would need... how can i make the extrusion without the machine reseting the zero on each layer? cheersby Jorge Nunes - RepRap Host
Hi! I already have a xyz table with stepper motors from an old cnc. My idea is using it to make a reprap/cutter. However, the table is larger than than the 160mm. How can i change the software to allow to use a bigger table? thanks in advanceby Jorge Nunes - RepRap Host
I've made my own cables... and confirmed the connections too many times... I can't make none of the opto work... either way, i won't bother about the opto anymore... that part is working and reliable now, so, no point in wasting time, specially when I'm going to have to make a completelly new extruder... the screw and wire "theory" is not reliable... gonna make it the old fashion way...by Jorge Nunes - Controllers
Ok, I just have enough headaches with this machine... even after the mods, the extrude just doesn't have enough reliability. The principle of having a screw pushing the wire just isn't good enough. Just works well on paper. even if it carves well, with any resistence it just stops extruding because it destroys the wire. and then, you loose hours and hours of work, not to mention the patience. so,by Jorge Nunes - Plastic Extruder Working Group
Well.... the opto still don't work, even in debbugging mode... however, the good news is that i finnally solved the problem with the contact switch! the arduino is so sensible that can detect any electrical discharge... so, as we are using double switch, i connected the ground to the switch, so that when it is disconnected there is contact to the ground. like that, just became perfect!!!!by Jorge Nunes - Controllers
Well... I've built 6 of them (ordered from the states), and replaced the sensor (bought here in Portugal) on 3 of them, and all behaved like that... So, I would have to be a very unlucky guy to have all 9 of them with defect... I've already checked again and again the connections and the soldering, but I'll check again, just in case... I have already connected it to the 5 volts (not on arduino)by Jorge Nunes - Controllers
I just forgot to add the pics...by Jorge Nunes - Controllers
Hi! Here are the pics...Between the ground and signal there is allways 5V, no matter if i stop the beam or not, or even if i disconnect the emitter part... I'm using the 2.1 version of the opto endstop... I've got 6, plus 3 extra sensors (all of them are H21LOB. I've got the kit from the link in the Reprap website) and still didn't managed to make them work... I have already tried to debugg likeby Jorge Nunes - Controllers
Hi! We are having a lot of problems with the assembly'working of our reprap. The most recent, without any scientific reason (at least, that i can find). Let me describe it: We had unsolved problems with the endstops... allways on, and we couldn't make them work. so, plan b), replace them with other switch.... simply connected the 5 V to the switch, and the other terminal to the signal.
