Ramps on steroids. Since I didn’t have very good results with the standard stepper drivers, I switched to a bigger version. Therefore it became necessary to create a bigger enclosure.
This is what it became.
Reuse > Recycle!
Very nice. Curious Minds want to know:
I see the Ramps up-top. What’s that in the middle, a transformer?
I see the four grey lines running to your humongous steeper drivers but what’s the silver, green & black box at the bottom?
You’re currently running 4 drivers but your box is wired (plugged?) for six, love expansion 
What’s the resolution of your drivers? 1/32? 1/128?
What’s the solitary beige line that’s connected around the outside of your case?
@Woody_Williams The thing in the middle is a solid state relay with a cooling block, since I use 230V for the bed heater.
The silver, green and black box is a 10 Amp 24VDC power supply.
It’s wired for 4, actually.
My steppers are configured for 1/32.
The beige line is the usb cable, still some work to be done.
All the wiring is shielded, btw. In a previous build I discovered that my hotend temperature fluctuated a lot in the lower temperature region when a stepper motor was engaged. I also noticed, that when the ramps was completely powered down, the lights on my optical endstops would flash when I turned a stepper motor manually. I figured this could never be good, The shielding prevents that from happening.
The idea is, that with this setup, I can use the same electronics for future printers.
What printer are you currently controlling with that rig?
My own build. Currently my usable build envelope is 400330400 mm. That’s why I am using 230VAC heating.
Heating this baby with 12V or 24V, would take forever. It isn’t printing much at the moment though, I’m rebuilding it. I had considarable Z-banding, and the only solution was a complete rebuild. I now have 3 small nema17 stepper motors driving the Z-axis, which is finally working perfectly.
could we see a photos of your baby? 
@Rien_Stouten Yes. Pictures, please.
Why do you want to see pictures of a big contraption with ty-raps and wires sticking out at every direction?
I hope to have it printing again in a couple of days, anfd will post some photo’s then.
Same reasons we like seeing re-purposed computer cases and microcontroller boards… brain damage 
We look forward to your update.
yeah!
Soon. I promisse. But it’s nothing special, just a printer. Nothing out of the ordinary, nothing even remotely special like @Shauki 's weird but brilliant inventions.
@Shauki I’m not very proud of the road I took. For starters, I thought I could do so much better than most designs, but in the end I ended up with a standard wade’s, a e3dv6, and a box full of aluminium parts, ready for recycling. And I wouldn’t call your ideas stupid, Shauki. Innovative, sometimes brilliant, sometimes not very practical, but still note wordy.
Like your mechanism with cables to ‘level’ the bed. It didn’t work for me, but I’m using the principle now on only one side of the bed, and that’s working fine.
So, in a nutshell, I cannot be as open as you, it’s not im my nature, but I do thank you and others for sharing their mistakes and wins.
Pololus and particularly, bad pololu knock-offs, don’t necessarily hold up well. A RAMBo probably would have done it without a sweat though.
But seeing people try alternative drivers is good. That type of driver is generally very good.
Well, I very much doubt that a Rambo would have made much difference. My project is way to heavy for small stepper drivers.
About the drivers I am using now: They were kind of bad too. These are cheap chinese drivers. First inspection revealed there was no thermal paste between the driver-chip and the cooling block, so I had to do that myself. After using them for a while, I got the impression they where not delivering power to spec. After some research, I found that they were limited to 30% torque. A little bit of soldering remedied that. After all that, they work amazingly well. No more skipping steps.
( Which resulted in a complete redesign of my printer, because now it became clear that it would never work reliably, no matter how strong my motors were.)
It looks very similar to my CNC Machine’s electronic enclosure made from a gutted HP Workstation lol
