Re: Rumba board - 9 years ago

Did you resolve this issue? I have the same problem.

Re: RUMBA won't connect and fan don't work - 9 years ago

I found the fan problem. There are 3 pins next to where you hook up the fan. 2 of them need to be jumped together. Still can't communicate with computer though. I tried using the usb pins instead of the plug and it didn't work either.

RUMBA won't connect and fan don't work - 9 years ago

Hooked up my RUMBA board today. I have 2 problems. First, everything was working but the fan. It wasn't getting any voltage. I went to change some settings in the Marlin firmware, and when I went to upload it, my computer will no longer find the board and I can not select a com port. It worked 30 min ago, but now it won't. I plugged in my Arduino to see if it would find that, and it did. What sho

Re: Heat bed plug melted - 10 years ago

No. I read somewhere that it's from the plug wiggling as the y moves. So I cable tied the wire to the frame an inch or 2 from the plug.

Re: Reprap stops mid print - help please anyone - 10 years ago

Are you using twisted wire on your steppers? The wires in each churchy should be twisted together for the entire length. If not, it will create interference which can cause the printer to stop.

Re: i3 shifting on Y-axis (tried quite a few things :-D) - 10 years ago

I had the same problem but much worse. I connected an LCD 2004 and eliminated the use of the computer and it worked perfectly. I bought mine from geetech.com.

I don't know. They came in the kit. So they should be the right ones.

This is the plug for my heat bed. Anyone know what might have caused this?

Re: Fan wiring??? - 10 years ago

This is where the fan gets connected, but the pins are not on my board. Does anyone know where I can buy the male and female ends from?

Re: Fan wiring??? - 10 years ago

Yes, but my problem is that the LCD 2004 plug takes up ALL 20 of the IO and ISP pins.

Re: Fan wiring??? - 10 years ago

For the print. There is only 1 extruder output. I would like the option of turning of and on with the slice settings.

Re: First print not working so well - 10 years ago

Well, I stopped working on my printer for a few months and now have returned to it. After trying the above suggestions without any sucess, I hooked up a LCD 2004 and now everything works fine. It just didnt like my computer I guess. My steps per unit worked perfectly using the calculated values. Thanks for the help everybody. PS I do like Cura better Vitaminrad. Thanks

Fan wiring??? - 10 years ago

I am using a Sanguinololu 1.3a, Marlin firmware and a LCD 2004 control. How would i hook up a fan to my hot end?

Re: First print not working so well - 10 years ago

When I first tried calibrating the drives, I shorted them out because I used an all metal screwdriver. I replaced them and then when I set my steps per unit, they were way off from what they should be as you can see in the screen shot above. Could I have also messed something else up causing my steps to be so far off? My x and y have the same steppers, belts and pullys so the numbers should matc

Re: First print not working so well - 10 years ago

I read that if you don't have a steady reading on the hot end that the printer can malfunction while printing. My temp does fluctuate. Do you think that could be my problem. It moves up and down by 5 degrees. I have new thermistors on order.

Re: First print not working so well - 10 years ago

I got my Vref's all set, switched baud to 115200 and I still have the same problems. Pattern is shifting, getting checksum errors and serial errors. Serial Error: Line Number is not Last Line Number+1, Last Line:0 Resend:1 What should I try next?

So I am getting 42byghw609 Vref=.476 and 42byghw811 Vref=.7 Is this correct?

Re: First print not working so well - 10 years ago

Quoteblbergeson It looks like there should be 3 jumpers under each driver. Not familiar with Sprinter. Will have to download and look through it. they are all there

Re: First print not working so well - 10 years ago

i just tested the voltage of my stepsticks and they were all different but under .5V. What should they be? I read 1.45V somewhere but when i tuned X to 1.45, it is whining and grinding.

by kevbme - Reprappers

Re: First print not working so well - 10 years ago

The board came assembled. There are jumpers in there but I don't know if they are wrong or not.I didn't touch them. What should I look for in the firmware? I have the wires set according to the schematic. I use pronterface and didn't see any micro stepping settings in there.

Re: First print not working so well - 10 years ago

Yes I am using gt2 with 16 tooth pulley. I know those numbers are way off but that's what I set them to so I get the right travel. If I tune differently the motors don't work. I think I did slow the baud before but I can try it again just in case.

Re: First print not working so well - 10 years ago

Here are all of my settings. As you can see I had to change the axis steps in sprinter by quite a bit. Is that normal? 1) After making several attempts to print, I seen that the pattern shift was not consistant. It shifts at different times within the first 2 or 3 layers, and shifts in different directions by different ammounts every time. Twice, it took off on Y until it hit the endstop and ano

Re: First print not working so well - 10 years ago

It seemed to be too close to the glass blocking plastic from coming out on the first layer, then to much after so I offset z up .2mm. Then not enough plastic was coming out, so I set width to 1.2. the pattern was shifting during infill only. So I slowed that down to 45. Still have the errors though.
