USB connection not working (Page 1 of 2)

Buy a Rumba
Seriously all you can do is look around for a short or something that seems out of place.  That board should connect to your PC Without power or anything else plugged into the board.  So that gives you something to start with.

if you are in the US, buy here: http://www.makerfarm.com/index.php/prin … board.html
(note: you will need to add stepper drivers x4, and add the USB cable - it is a mini B type)

Since it a workbench with dual extruders, don't I need 5 stepper drivers?

Tips:
Avoid GEtech drivers
Don't power the board with drivers installed unless the motors are wired up also.

give me a minute, I also like Maker Farm.

I got my order in the cart, and it looks like I will need to by an extra 4988, because you have to buy 4 steppers with the board.  If I had ordered yesterday, I could have gotten 20% off, but now the code is expired. Before Iplace this order, does anyone know if there are new coupons available? 

Here is a video of an artwork I'm working on that I used a 3D print on before I started having problems with my printer.

They said they don't use coupon codes. so I just went ahead and placed the order.  I got the board, usb cable, 4x 4988, and 2x 8825. about $150.  So thats about $300 in hardware upgrade/repair so far on my $1300 printer.  This is getting expensive.

Thanks again for the help.  I'm looking forward to getting it up and running again. Luckily I printed the new mounts before everything went south.

yup, once you get it all installed, flashed and tuned in you wont be sorry.

I put a Rumba on my 1st SD4 and love it - it is my most reliable, most accurate machine out of 4 printers.

as for the cost invested so far - just remind yourself that there are those that spend a whole lot more than you have for a closed source, difficult to upgrade & tweak machine that has major extruder problems - not naming names, but I bet you can guess.

LOL, yes it does

I would be interested in hearing how the Azteeg works out for you, Carl (and you have a PM)

Back on topic - the nice thing about the SD's is that they are soooo easy to modify once you learn the basics of the machine. They have (had) a good platform, just the implementation was a bit lacking...

I would love to get my hands on a workbench. Oh the things I could do with/to it! LOL maybe one of these days...

For a while, yes.  The Rumba will take up to 36v so you'll have options moving forward.  A good Supernight 12v PSU can be adjusted up to about 14.5 volts.  This can seriously improve heat up times.  So id start with your stock PSU and then when you want a little upgrade you can grab a new PSU.

The Rumba will arrive today!

I have the extruders mostly assembled, and have the new mounts printed.
I plan to use the existing power supply, which I assume I only need to cut the connector off and strip the wires.
I have a multimeter, and plenty of wiring experience.
The old controller is dead, so I can't use it.

Any links to setup documentation for my Solidoodle Workbench, driving E3D extruders will be greatly appreciated.

I was planning on using auto level, if that's how the workbench normally works.  I'm used to seeing the printer sample at 16 points before the print.
