I am a little confused as to why you are concerned with what display to use. Assuming you are using Marlin the control of extruders will be software and configuration controlled. The rumba board if I recall has 6 stepper controllers so with the cube that could be X, 2xY, Z, E0, E1 and E2 (using the Y output to drive both cube Y steppers). Marlin 2.0 is capable of then driving 3 extruders and yoby jimboh3 - General
The BIQU Pro 1.1 has 6 stepper drivers but has pin outs for dual Z's. I just changed the pins settings in marlin so that the 2 Y steppers of the cube are connected to the Z outs and the Z to the Y out. Then E0, E1 and E2 are available for the 3 extruders.by jimboh3 - General
BIQU (Bigtreetech) have newer boards now with even more functionality. I bough all my stuff on Aliexpress. Bit of a wait but cheap. Sure I can let you have my marlin config. As a starting point maybe. Its not much use unless you have the same board with the same steppers and number of extruders etc. Marlin configs are very specific to a build I find. Display is a BIQU TFT3.5. They also have a 5"by jimboh3 - General
Me Too. @GT500 I use the 32bit BIQU SKR Pro v1.1 with TMC2209 stepper drivers and a diamond triple extrusion single nozzle head (see my post a few up). Its all built and running well now, only thing not fully up is the 3 filament runout sensors because Marlin wasn't fully supporting when I was finishing this. Should try again but I tend to do most of my 3d printer stuff in the winter. See lastby jimboh3 - General
Used my Cubex RepRap Tango to make a Mostly Printed CNC, Turned out great. My new project is my second Cubex duo conversion (I bought two originally for $220 IIRC for the pair). This one is based on a BIQU SKR Pro v1.1 with TMC2209 stepper drivers and a diamond triple extrusion single nozzle head. I stripped the carriage down completely and removed the sliders/bearings.

In case anyone is interested in the issue/solution. I had servo0 defined as PWM2 but I had it plugged into PWM1. Ok so that would never work right? Only it did work albeit a little intermittently with the 3DTouch. How? I had a wire to PWM2 in the same screened cable that I had cut off at the BLTouch end. Went nowhere. The 3D touch must have been picking up the signal from the PWM2 wire. Anyway,by jimboh3 - Firmware - Marlin
I have been using a 3Dtouch on my Tango(Rumba) converted CUBEX Duo for some time and its reliability got to me so I decided to upgrade to a Antclabs genuine BLTouch. They are pin compatible so I expected it to work straight out. But it doesn't. It self tests and lights red, no blue. It does not respond to any M280 commands and M43 S does not make it self test. I plug my 3Dtouch back in and M43 dby jimboh3 - Firmware - Marlin

Be careful with the extender leads, I bought some for the CNC i Made and they crossed over two of the wires. Its not safe to simply work by color.by jimboh3 - General
You could try removing the hot end from the extruder and check see if the filament feeds. But you would have to have marlin configured with no min temp for extrusion (can't recall the setting off the top of my head). If the hotends are clear of obstruction it should not take any more torque to push through the stock end than a E3d I would have thought. I have 8255's but only set the current at 1.by jimboh3 - General
Isn't that 2.3A? Also Isn't that a tad high for a A4988? Sorry I have not been thinking 3d printers for a month or two and am getting old so memory fades quickly. I am surprised the extruder would need much current, it isn't doing much work is it? Are you still using the original delivery system with the filament fed via the tubes? Have you tried a length of filament fed straight into the top ofby jimboh3 - General
QuoteGT500 Noticed the fans that are installed in the base blow up so maybe start there and add a couple small fans at 90 degrees to blow across the drivers. I installed my Tango (mod of rumba) over the front of the two fans using a printed mount and pillars so that front fan is blowing on the underside of thePCB where the stepper drivers/ Mosfets are and I installed a new cover over the top wiby jimboh3 - General
Quotemonkey Either way the clone seems to protrude enough with the super long threaded adapter, don't know how well that'll print. Rather than increasing the size of the hole in the carriage to allow the the e3d heatsink to be fitted, I went the same way as others have and used a e3d with a bowden end and turned the bowden nut down on a lathe until it would fit inside the Cubex extruder. That waby jimboh3 - General
Sorry mate, they are just the details that kissslicer gives at the top of the gcode file where it reports all used settings. The travel_speed_mm_per_s = 500 would have been commented too but for bad cut and paste. So what should that be? are the rest ok? xy_accel_mm_per_s_per_s = 1500 perhaps too high and should all the rest be below 50? Those two are both set in kisslicer, guess I never changby jimboh3 - General
I have a second Cubex Duo that is stock except mods to allow normal filament. I am considering reprap'ing that one too and this time go for a triple Bowden solution with a Diamond triple (3 into 1) hot end. I have been thinking about further weight reduction on the center carriage. Anyone considered (or even done) removing the aluminum carriage completely and replace with a 3d printed carriage?

I only use one E3DV6 on my modded Duo. It is in the middle position and I use the Duos extruder fan mounted on its bracket (with screws) and have a BL touch probe mounted to what would, on a trio be the third extruders bracket. That is after both the chinese e3d small fans failed. The Cubex fans are better quality. I have had not problems with cooling with PLA. Haven't tried ABS yet. I use a Tanby jimboh3 - General
Nearly finished my Cubex duo reprap mod. Using a Tango (modified version of Rumba). With DRV8255 drivers (6 of). I re-used all existing wiring, just new connectors on the board end, and also reused the sensor boards and the existing breakout board on the carriage. Have E3DV6 style hotends but kept the original fans (two of the cheap 24 fans that came with the hot ends packed up within a week). Onby jimboh3 - General

Never mind. I finally came to my senses and realised that for no reason at all I was trying to set it up to work the same as the CUBEX. Finally, after too many hours playing around, printed my first test print and am simply amazed at how much better it prints than the standard Cubex. And that is without any fine tuning.

I am in NS Canada and saw an ad on Kijiji. Had to drive 3hr round trip to get them but thought it worthwhile.

Thanks guys for the swift response and good reading including the link. I should have mentioned that I am also a tinkerer. Get a ton of pleasure out of building this kind of stuff. I am familiar with using SSRs as I am on my third incarnation of electric brewery build and PWM 4.5kw elements. If I went for an AC heat bed I assume I would need an SSR for tighter heat control using PWM? Or do you juby jimboh3 - General
