UPDATE: 10/25/17 - Turns out the 6 Amp PSU they send you was causing my voltage dips and blobbing. Gave it a 12v 12.5a Psu and runs much better. Still working out the bugs in getting a Arduino DUE clone to work with a geeetech RAMPS FD V1.2. Firmwares limited. Marlin4Due doesnt wanna work. But Repetier FW seems the most likely. You don't need the electronics upgrade. Just a PSU. the 12v 6 amp psu doesnt even carry power anymore

Solid printer but requires upgrades. Heat bed is easy with an SSR, 24v PSU, and 24v heatbed. But the electronics on this REALLY hold it back. 16 mhz 8 bit mega 2560 won't run this printer faster than 25mm/sec at .4 layer res. at 30 it leaves blobs. firmware won't flash without autobed leveling being enabled even though it doesnt have that feature. This doesnt let you disable the sensor "sag" check every 30 seconds. Best you can do is set it to 99 seconds to get 5mm per seconds more without blobs You need to DL the firmware if you upgrade to a hotbed. But beware again cause of the auto bed leveling settings that need to be there for it to function, you only can get 25mm/sec.

Electronics upgrade -
Arduino DUE clone by osoyoo for 21$ on amazon and is prime. But since DUE is a 3.3v computer and the mega 2560 is 5v. You cant use your current Ramps 1.4 with it cause it returns 5v to the mega or due. and the Ramps 1.4 is 5v data as well.

Ramps FD - 28.99 -40.00 depending on where ya look, I snagged one on eBay for 28$ cause I had Paypal money.

For Firmware get Marlin4Due. Its been pretty straight forward, you just need to copy the delta kinematics like the length of the rods etc from the firmware that came with this, to the marlin4due configuration.h. When you get marlin4due firmware, you will see example configurations, click that folder, then click the delta folder. Copy those two configuration files into the folder with the .ino for marlin4due and replace the existing which is for prusa types for a solid delta template. then just copy all the old specs to the new firmware. Once I have mine working ill post my config files into this comment.

once thats done this can have a max travel speed of 600-800mm/sec. (even though id never run that) 400mm/sec travel speed and 120mm sec print speeds should be doable with this. But

Ramps FD $29 +
DUE Clone $21 +
SSR $11 +
24v PSU 20$ +
Sinitron 220mm 24v 144w heatbed $20 =

101$ + time to make firmware work and re calibrate. But once you do this thing can print 20,000 mm bridged prints in 30 minutes.
