Re: RAMPS (w. Marlin) won't move or heat with new extruder - 11 years ago
Really strange the extruder works sometimes. I even was able to start a print but after the first few layer it startet stuttering and it seemed like it didn't have enough juice to pull the filament if I helped it along it went fine but it didn't turn it by itself. I tried adjusting the poti on the stepper controller but it just increased the volume of the stuttering.by mostley - RAMPS Electronics
Re: RAMPS (w. Marlin) won't move or heat with new extruder - 11 years ago
so I tried swapping X and Y. and now the Y-Axis (controlled through X-Axis controlls) has the same problem. After changing back I changed the stepper controllers, and now it works on all axis O_o so now every axis is working except for the extruder. some day this machine is going to be my death...by mostley - RAMPS Electronics
Re: RAMPS (w. Marlin) won't move or heat with new extruder - 11 years ago
no the RAMPS is bought. And did work for about half a year before I changed the extruder and started breaking things -.- I'll try the swapping right away.by mostley - RAMPS Electronics
Re: RAMPS (w. Marlin) won't move or heat with new extruder - 11 years ago
ah that probably explains it, they aren't 18 AWG. I'll swap'em with thicker ones. hm not sure if the endstops are at fault here, because they work. I can run the motor into the endstop and it stops correctly. Also all the other Axis work fine except the X-Axis. I tried min_software_endstops false but didn't change the behaviour. The behaviour isn't that it won't go to negativ. It does go butby mostley - RAMPS Electronics
Re: RAMPS (w. Marlin) won't move or heat with new extruder - 11 years ago
ok after a bit of fiddling I found the problem, it seems the connection to the power supply was fried and created a high resistance, somehow the connection heated up and the cable melted into the plastic... No idea how that could have happened though... Now that I renewed that connection it seems to work fine. After retesting everything, I tried to get the X-Axis moving but it now only moves inby mostley - RAMPS Electronics

Re: RAMPS (w. Marlin) won't move or heat with new extruder - 11 years ago
So I just ran some tests and pretty early I noticed a strange behaviour. When I measure the voltage on the input block coming from my power supply I get 13V but when I plug in the USB into my laptop the voltage slowly drops down to 0.6V and then stays there. When I unplug USB it rises again. How strange is that? Does that mean my power supply is busted? I'm utterly out of my depth nowby mostley - RAMPS Electronics
Re: RAMPS (w. Marlin) won't move or heat with new extruder - 11 years ago
Thanks, I'll try that this evening.by mostley - RAMPS Electronics
Re: RAMPS (w. Marlin) won't move or heat with new extruder - 11 years ago
Hi Sean, thanks for the quick response. I tested the Voltage output of my power supply as it reaches the inputs and it shows it's 12V. I should probably check if the current reaches the mosfets (I guess it uses mosfets...)? Where can I find them on the board? This thing is more confusing than the london subway system:by mostley - RAMPS Electronics
RAMPS (w. Marlin) won't move or heat with new extruder - 11 years ago
Hi, tl;dr: - no motor movement - no heater - but temp-data -> how can I test if RAMP-Shield is fried? last weekend I upgraded my Mendel to 1.75mm filament. So I added a new Extruder and a new HotEnd (Budaschnozzle). After everything was back together I heated the machine up (via pronterface) and started test extruding a bit. Seem to work ok. While slic3r was slicing a model I started cleaby mostley - RAMPS Electronics
Re: RAMPS 1.4 Stops heating - 13 years ago
I found the problem: I connected the heatbed to Pin 9 instead of Pin 8 because ReplicatorG didn't recognize it on 8 but since I'm using pronterface now it works with 8. What I didn't know is that only pin 8 ist connected via the "big" fuse so the small fuse heated up each time and cut the power completely.by mostley - RAMPS Electronics
Re: RAMPS 1.4 Stops heating - 13 years ago
I'll watch it again but I don't think so. I didn't start printing yet only sending individual gcode commands via pronterface.by mostley - RAMPS Electronics
[SOLVED] RAMPS 1.4 Stops heating - 13 years ago
Hi, I'm experiencing a strange behaviour with my new RAMPS setup. I'm using Marlin as firmware and Pronterface as Host-Software. The electronics stop heating if I simultaneously enable the extruder heater and the bed heater. The extruder alone works fine but after a (~) minute of heating the heatbed both stop heating, pronterface doesn't notice (only through the dropping temperature readings).by mostley - RAMPS Electronics
Re: 13.3V with RAMPS 1.4 with 1N4004 diode - 13 years ago

13.3V with RAMPS 1.4 with 1N4004 diode - 13 years ago
a kind of longish post is going to follow, so I tried to highlight the important questions for the skimmers Hi, I got my RAMPS 1.4 yesterday and still got a few questions before I start plugin stuff together and potentionally endangering my electronics and myself I asked my supplier and he told me that the board has the 1N4004 diode, where can I find it on the board? I read here: that Iby mostley - RAMPS Electronics
Re: Teacup connection Problem - 13 years ago
I did try to change it. It was what my gen3 used before. So should I try again on 115200? Is there something to change in arduino for that to work?by mostley - Firmware - experimental, borrowed, and future
Teacup connection Problem - 13 years ago
I tried using Teacup on my Techzone Gen3 Mainboard. I was able to compile and upload it, but I get Errors trying to connect: Repsnapper: Connection Timed out ReplicatorG0024: RepRap not responding to gcode. Failed to connect. I tried configuring other Baud rates but I'm pretty sure I need 19200. Is there something else I could try? Thanksby mostley - Firmware - experimental, borrowed, and future
Re: Stepper Motor Twitching - 14 years ago
So, I connected one Mainboard pin, one pin on the stepper driver board and the stepper driver enable directly to gnd on the power source. It doesn't change the behaviour at all. I think that the 0.3R is just my crappy multimeter.by mostley - Controllers
Re: Stepper Motor Twitching - 14 years ago
so, I should try and connect any ground connection on the stepper board and the mainbaord with the ground from the power source? Or are there some ground connections better suited for this task?by mostley - Controllers
Re: Stepper Motor Twitching - 14 years ago
I think 0.3 is the measurement failure of my multimeter....but will check that tomorrow again. oh another thing I saw is whatever I set in repsnapper, reverse or normal Direction always is the same. The exact number I will test again tomorrow too. Thanks so far for the new input.by mostley - Controllers
Re: Stepper Motor Twitching - 14 years ago
just remembered I also already tried to connect an axis controller to SDA/SCL but strangely didn't do anything, the motor didn't even energize. I think I could do a live stream while in IRC or something perhaps some visuals could help?by mostley - Controllers
Re: Stepper Motor Twitching - 14 years ago
Well like I said I think the wiring is correct because the motor turns if connected to the main board as an axis. I just switched the SDA/SCL -> 10pin-header connection to z-axis -> 10pin-header and it ran perfectly. So I figured its neither the wiring nor the motor, right?by mostley - Controllers
Re: Stepper Motor Twitching - 14 years ago
Well turning the pot on the board only changes the intensity of the twitching, so if there's no other way to do that I think thats not it :/by mostley - Controllers
Stepper Motor Twitching - 14 years ago
Hi, I got some Problems running my Stepper Motor. So far neither Forum nor IRC-Channel could help. So I'll try to recap what the symptoms are and I've already tried. First the setup: * RepRap Mendel * Gen3 Techzone Remix Electronics running FiveD Firmware 20100806 * 4th Stepper Driverhooked up to SDA/SCL on Mainboard and shares power lines with extruder board. * Stepper Driver Pin 5 hooked to Gnby mostley - Controllers
Re: Stepper Driver Board is overheating - 14 years ago
@davmj: I think the ReplicatorG Firmware already does something similar. Also it does not use the poti on board, instead there is a textbox to type in the PWM value.by mostley - Controllers
Re: Stepper Driver Board is overheating - 14 years ago
So, now I got almost everything working, the steppers do step, the endstops react and with them the motors, the extruder board communicates with ReplicatorG and controlls heater and fan. The stepper driver heat Problem is still to be fixed. And what I would need some help with: the extruder controller getting its motor to turn. All it does is let the motor hum in different sounds dependung onby mostley - Controllers
Re: Stepper Driver Board is overheating - 14 years ago
Why i thought long cables could be a problem: i need to Set the Motor current on the Stepper board with long cables very high or else the Stepper won't move a tick. It gets loud and produces this high pitched sound. I already tried this board with shorter wires and it did Not Need such an high current.by mostley - Controllers
Re: Stepper Driver Board is overheating - 14 years ago
So I did some of the things you told me to and got the other 2 steppers running smoothly. Thank you for that! Only one still troubles me because despite running it still heats up and makes more noise than the others. I think the problem with this one is, that it uses the longes wires to the stepper, also the thinnest. Probably a really bad combination. What cable thickness would you guys recommeby mostley - Controllers
Re: Stepper Driver Board is overheating - 14 years ago
the opto endstops are connected but do not work either, the LED is always off.by mostley - Controllers
Re: Hi german reprappers, where are you? - 14 years ago
Dann stell ich mich und meine Maschine doch auch mal noch vor. Ich bin Softwareentwickler in Karlsruhe und bastel mit einem Kumpel am Mendel bereits seit Dezember. Die Mechanische Konstruktion ist bis auf die Zahnriemen (es fehlt mir doch der belt-split) und dem kompletten Extruder (fehlt auch noch Plastik) fertig. Das Plastik das mir noch fehlt ist jedoch angeblich bereits in der Post. Die Elektby mostley - Schwarzes Brett
