Anybody tested this control board? I have home brewed delta 3D printer and I’m really confused that I must slow down printig just because of low performance of atmega in ‘classic’ arduino/ramps/pololu board. This has powerfull processor and nice user interface…

What’s with firmware support? I mean, Repetier or Marlin. My choice is Aeduino Due + RAMPS-FD with Reprapdiscount SmartController or Full Graphic Smart Controller
Looks like proprietary firmware. It’s 32 bit and the screen shots show a Chinese loader thing. They don’t talk about a firmware name anywhere other then “machine parameters on sd card” and “use software to flash firmware”. Maybe a Chinese smoothie clone?
I found nice article about it: http://3dprint.com/35824/chitu-3d-printer-motherboard/
I think I will order it!
(and I don’t want smoothieboard)
I like how they used a crappy STL vs a nice one for their comparison. Its still using the A4988 chip so there’s no way changing the firmware did that.
Oh, yeah, 3Dprint.com articles. Quality journalism.
I would advise against getting one. It’s proprietary firmware which may contain bugs or not support certain features, with no certainty of future firmware update.
The only real reasons to go with a 32bit board would be a) you have a Delta (which the Termistor doesn’t seem to support) or b) you want the features Smoothie gives you. With 115200 baud, the Termistor can not perform better than any old AVR-based board (unless you only print from SD - but in that case, AVR aren’t limiting Cartesian bots, either).
@Thomas_Sanladerer With a 1/32 microstepping resolution, graphic controller and several activated features (for example, Advance Algorithm, etc) it is too much for AVR. This is my experience with Marlin and Repetier.
But the a4988 are only 16th stepping, and I doubt there are any of the advanced features like volumetric extrusion in their firmware.
@Nathan_Walkner that’s a pretty common misconception about microstepping: You don’t actually “lose” holding torque. The absolute deflection for a given external torque will be the same no matter if you’re using full steps or 1/256 microstepping. However, as you increase the microstepping ratio, each individual step will create less torque (as you’re also decreasing the deflection), but for a given absolute rotation, the generated torque will stay the same as you’re also increasing the number of steps.
Microsteps can help make your printer more silent and decrease ripple patterns if your drivers are working properly. Though for any “normal” printer, 1/16th microstepping is just fine.
well I started a reply and then Thomas 
…so nobody.Thanks anyway!
I also try wifi esp8266 with Chitu board.
You need to update firmware option board
@Nathan_Walkner ok thanks response.
I read it to be difficult settings stepper
I have yet to try
I have a printer with delta pulley GT2.5 16.
I tried to mount esp8266 and now does not work once removed does not accept AT commands.
