Welcome to the SeeMeCNC Community

Hey thanks. So by the cold extruder calibration you mean the triffid hunter calibration? http://reprap.org/wiki/Triffid_Hunter%27s_Calibration_Guide ^this one? If so whats the easiest way to figure out this information? Know your stepper motors' full steps per revolution value. steps = 360 / angle ...

Finally printed out my first test cube. Its far from being perfect, I have not done any fine tuning yet on the extruder, and i think i detected some slight slanting as well, accepting any and all tips for fine tuning, so I can make my next cube a perfect one! Thanks in advance [img]http://i131 ...

Okay so i tried a bunch of things recently I got the new recent new repetier host 1.0.3 I uploaded new firmware 0.91 I edited it to include my configuration values; PID, radius, height, and put baud at 250000 I tried swapping the cables but that didnt really do anything. I am still having the same ...

bamp

Okay so got around to checking the firmware it says

Repetier 0.83 in the log

Yeah my LCD screen does not seem to boot up when i fire up the machine.

Its just blank, I switched my board a while back because it had a bad bootloader.

I think the screen is confused about the switch or something.

There is no issue with the wiring it is wired exactly as is stated in the manual.

Hey

I checked out the firmware in device manager Windows 7

It says driver version is 1.0.0.0
Signer: ultimachine

I do believe i am running a v1 it came with Steves extruder as the default extruder.

Hi Im calibrating the printer radius, and the most recent manual says i need to set my EEPROM to 0 so as not to avoid issues while calibrating printer radius. I changed the EEPROM value back to 1. But now the printer is still not responding, it was responding just yesterday. This is my second time ...

Hey not seeing anymore smoke so everything seems fine now. Just a question I am now configuring the end stops, and i am slightly unclear about the instructions in the manual. Should the heat be on while i do this? How is it different from configuring the Z height, also I dont quite understand the ...

Hi yeah so i did the whole foil thing again yeah it smoked up quite a bit like before, but after about 1 minute the smoke stopped. Whatever was burning apparently got burnt up already, i let the machine sit at 190C for a good 3 minutes, plus cool down time and no more smoke came out still i think it ...

Hey HI UPDATE The wiring was a little off i fixed it everything works fine now. Ran the PiD weirdly though i got 2 PID values, not sure whats going on here. Also after the PID routine the arm giggled a little, it was a bit odd, thought i should report these minor hicups anyway. By the way these are ...

Hey trying to run my PID command M303 P1 S60

It brings the temperature up to around 54C then i get this message PID autotune failed timeout.

not sure whats causing it, the board seems to heat up just fine though, not sure whats causing it to stop.

Is it a power issue?

Hi @Tinyhead I actually did this but my resistors ended up getting singed around the edges, where the resistors are open, not sure if i am doing something wrong, but i did exactly as was pictures and i still got wisps of smoke. Not sure whats going on,maybe i didnt wrap them tight enough i will try ...

Hey thanks for the reply Covered the resistors in RTV I was pretty thorough still got smoke bubbling up from the hot end though, I think the variety of RTV i am using is not ideal. (its silicon based) I am considering just using a heater, is there a particular type of heater that you can recommend ...

Hey Update my resistors arrived in the mail recently, and I just want to know, what is the best technique for wrapping the aluminum foil around the resistors to prevent shorts? Also what is a good ammount should i totally cover the thing in foil or just put a little. Any good suggestions to make ...

Hi Eaglesoar

You are absolutely correct, there is no sense in turning something this delicate into what would ultimately amount to a learning session.

I will order a proper adapter and follow the video to precisely.

Hey guys my supplier said that if i use single pin jacks, then i only need to connect 1 ground to the Rambo, can you guys confirm this?

It seems sensible, but what did toyguy mean when he said you can put all the ground wires into one?

Alright guys so it looks like I have a bad bootloader So I plan on flash booting a boot loader to my rambo. [img]http://i131.photobucket.com/albums/p283/photofool88/2013-04-13-113_zpsfb8f3e09.jpg[/img] This is an Atmega programmer, it is compatible with Atmega 2560, which is the part type of the ...

Hmmm thanks Toyguy. This issue arose when i first tried loading firmware onto the Rambo, I ordered my kit back in july, that was when the motors were still the older ones the black/blue/red/green wires, so its the Rambo that comes with that kit. I am going to do more research and get to the bottom ...

I really don't think anything is wrong with the hardware because since last week i hardly even laid a finger on the printer. The only thing i did was to move the arm up slightly which engaged the motors while they were off. I know one shouldnt engage the motors while off because its bad for the ...

Okay So i tried installed repetier on my other computer, and same issue.

Its definitely something to do with the USB, I wonder how this happened as far as i know nothing is different. I will buy a new usb wire and try that out.

I really hope nothing is wrong with my Rambo.

I also notice when i connect with rep host i dont see the familiar text which shows the software is interacting with the machine I guess what i should be seeing is something like the familiar message in the manual, external reset etc etc When i open rep host there is this text 12:26:28.756 : OpenGL ...

Tried emergency stop and reset Also made sure to completely close each program before opening the other. Tried re-uploading the sketch on arduino, same thing , it says done uploading then i close it it and open up repetier. When i connect repetier again, its idle for a bit then it says 7 command ...

Ah alright Yeah the first one actually was commented out with // i just didnt post the whole thing I reset the baud rate on the firmware, and I am looking at my manual control panel it still says command waiting. For Arduino to apply the firm ware i just, file, save and upload right? Maybe it didnt ...

Hey Geneb thanks for replying right away.

On repetier its 250000


And on Arduino firmware it says this

#define BAUDRATE 76800
#define BAUDRATE 115200 <--This middle one is highlighted in black
//#define BAUDRATE 250000
