Re: Confirming my construction, did I do this right? - 11 years ago
The endstops all work correctly now I have a picture here of how the filament looks when the extruder jams and I cut off the 'weird' part I'm really done with this machine now. I know it's not me that is messing it up, I feel like the guy I bought the parts from just tried to make money fast with shitty cheap components.

Re: Confirming my construction, did I do this right? - 11 years ago
The voltage on the resistor reads: 9.26 Volt I think my Multimeter only goes to max 10 Amps? It has a warning on the meter saying '10Amax - Unfused' I can't find any multimeters that have more than 10 amps measuring capability? Am I doing something wrong? I checked them all the way up to the 90 euros range, and didn't see any, I can't spend that much on a multimeter now, I already spend all myby Ohmarinus - General

I have finally managed to get everything done Not yet with all programming, but at least it's running now as it is. I will do the firmware upgrade tomorrow.

Re: Confirming my construction, did I do this right? - 11 years ago
Great, thanks for your help so far! I'm currently wiring up the heatbed also, the seller told me there has to be a relais between the sanguino and the heatbed, or if I didn't use the relais, I would have to hook up the MOSFET with a heatsink. (damn, tested it, there is no way I can hook up the heatsink with the MOSFET) So I am totally confused about wiring up with the relais, so I have decidedby Ohmarinus - General
Re: Confirming my construction, did I do this right? - 11 years ago
True true, I already have the arduino program installed because I have an arduino board also, not using it for this printer, but just for playing around. So, is it a lot of work to install new firmware on a Sanguino? What kind of data do I need to configure the firmware? Since the seller isn't giving out much info I don't have anything like hardware information. uGen Wrote: ---------------by Ohmarinus - General
Re: USB cable starts overheating when Power Supply is turned on - 11 years ago
Hi I'm using a sanguino with 4 stepsticks, so no RAMPS. But if it can't do any harm to just turn around the connector, then I will do that. Are you sure it wont do any harm? I have a picture here of my setup, I'm afraid I might have put the X-axis bar the wrong way around, the stepper-motor is on the left side of it and I see both ways in different images on the web, shouldn't it be on the rigby Ohmarinus - Controllers
Re: Confirming my construction, did I do this right? - 11 years ago
That is a very good question. The seller is very unclear about answering my questions. . Since he preloaded it for me and told me it should be fine as it is now... I have no idea exactly. But he did send me the firmware, but it's just an arduino installer and is also a windows exe, so I can't open that on my mac. He told me something about: Kliment Sprinter does that ring a bell? uGen Wroby Ohmarinus - General
Confirming my construction, did I do this right? - 11 years ago
Hi everyone, I have finally put my RepRap Air 2 XL together. I am totally new to 3D printing, the machine works, extruding works etc, but the endstops don't. Also I am starting to doubt I might have put my X-axis the wrong way around, or doesn't it matter? I have highlighted the placements of my endstops (orange) and X-axis stepper motor (green) in the attached picture. Can it be that the X-axiby Ohmarinus - General
Re: USB cable starts overheating when Power Supply is turned on - 11 years ago
Just by hand-tuning them I managed to get them all working on their lowest possible energy level. The only thing I find weird about the machine is that my extruder stepper makes a pretty annoying high sound, while all the others are all perfectly silent. Also another weird thing is that the stepper motors seem to move the wrong way from what is shown in the pronterface menu and when my motors hiby Ohmarinus - Controllers

Hey, thanks for your reply, I still haven't gotten things running. I also asked the seller of the equipment, he says that just turning up the meter slowly until the motors work as intended... Not sure if this is such a good idea, I have asked a friend who has put Vref at 0,7 and he says it works well.

Re: Soldering wires on hot-end? - 11 years ago
Okay, I managed to re-do my wiring for the hot-end. The hardware stores here in the Netherlands suck ass, none of them sell any good crimps and now that I found nice crimps, they don't sell the pliers for it. I'm so done with this country in terms of equipment knowledge.

Re: USB cable starts overheating when Power Supply is turned on - 11 years ago
Apparently all the other stepsticks were also burned. According to the seller who is checking my board now. Weird, because with those three stepsticks my board worked fine, it only didn't work with the one broken one. So apparently the other three were also broken but the sanguino would still turn on with those stepsticks in place. I am getting a weird feeling about this.

Re: Soldering wires on hot-end? - 11 years ago
Great! To be honest I think adding two aluminium plates at the point where the crimp goes, will also function as a heatsink. I have bought a few small aluminium coolers that I can connect there, the only difficulty is making sure these coolers don't short-circuit the machine, so I would have to add some sort of isolation. My hotend is also covered in black thermal paste, I think the seller didby Ohmarinus - General

Ai, good thing you say this, you see I have always worked with just a soldering iron, led lamps, small transistors, resistors and just fussing around with my Arduino...

Re: Soldering wires on hot-end? - 11 years ago
Great topic, I started to wonder if my way of connecting everything would be safe.. Guess I better use crimp connectors instead. Also, the wires on my stepper motors are rather short, I have been soldering them neatly onto 3M flatcable, but now I found this: 〈=NL Looks like a great way of connecting my steppers to the flatcable.

I know someone would say that, but I notice it goes wrong a lot and well I miss some kind of 'version control' on 'improved' items.

Re: Homeprototypes: use of MediaGoblin? - 11 years ago
What I don't like about thingiverse is that there is for example not a group for 'RepRap Air 2'. If there were groups like that, I could just click the group and see all prints that are connected with the Air 2 and see if there are any updated parts available. For now thats the only thing that I am missing in Thingiverse. I am still new though, so might spot other things. In Thingiverse it isby Ohmarinus - Object repositories

Yes, I will tell the seller that that might be the case! Thanks NoobMan Btw, is it just recent that the forum keeps being inaccessible?

Hey, it's not getting any clearer. I can't seem to find much wrong here..

Re: USB cable starts overheating when Power Supply is turned on - 11 years ago
I replaced the stepper that was broken on the Sanguinololu board, I turned on the device without the USB cable in. Immediately the stepstick that I replaced started to heat up like crazy while all the others were still at room temperature. It is the stepstick closest to the PSU input on the Sanguino board.

Re: USB cable starts overheating when Power Supply is turned on - 11 years ago
Yep I think you are right. But I'm still having the same issue, my USB cable fries when I turn on the power (correctly set-up this time). I just fried my second USB cable. It just melts the F* down when I turn on my power supply. Also the Sanguino can be accessed through USB, but when I turn on the power supply (which neatly gives me 12v) everything just starts heating up without any apparent rby Ohmarinus - Controllers

Re: USB cable starts overheating when Power Supply is turned on - 11 years ago
Actually it turned out my Multimeter was malfunctioning and the polarity was working correctly in the first case. Now after I switched the polarity I probably broke the Sanguino.

Cooling - 11 years ago
Hi, got this Sanguinololu, and now I am told that if I put a relais between the sanguino and the heatbed MKII, it is not necessary to put a cooler on the heatbed mosfet. I'm also told that if I don't use the relais, I really have to put a cooler on the mosfet of the heatbed, located on the Sanguino board. Is this true?
