I have my first 3D printer, a Creality Ender 5 that I've tried several boards on. The stock board works and nothing more - and it's loud. I first switched to an MKS Gen L with TMC2208 steppers and a fanless power supply - Wow, huge difference in noise levels. Then i jumped to a Duet Maestro (Genuine, not a clone) and it's an awesome board - ticks almost every box of mine except being able to customize, change steppers, etc. After that I bought an SKR v1.3 - great board that forced me to learn Marlin 2.0 since it's 32bit. I never installed it because I learned about the SKR Pro before i got around to installing it.
This SKR Pro was a bit of a challenge because of how new it is and there's not the same wealth of info like there is for say the Gen L. At first, I though my SKR Pro wasn't working because I couldn't see the SD card when I connected the board to my computer with a USB cable. Kingprint reached out to me right away and answered my questions and pointed me in the right direction. I still haven't connected this board to my printer because I'm happy enough with the Duet. But, I've got the firmware all configured and have tested it with steppers, LCD and thermister as well as the Wifi module. I'm collecting parts for a major overhaul and will install the Pro then - I'm really looking forward to that.
The overhaul will include the SKR Pro V1.1, BL Touch, Hero Me fan shroud on an E3D V6 hotend.
BTW - I've looked at touchscreens several times and I still come back to the RepRap smart controller 12864 as the easiest, most useful and sensible display of all - especially if you're using Octoprint anyway.
Bottom line on the SKR Pro V1.1 -
-Buy from Kingprint, they're great to deal with
-It's the most versatile and configurable board out there
-supports up to 6 steppers, 3 hotends, 3 fans
I have the board installed and began testing on my Ender 5. I had to go into Marlins' pins file and remap the endstop pins so they would work as X_Max and Y_Max instead of X_Min and Y_Min due to the location of the Ender 5's limit switches. I homed all axis and then moved them to their extents but discovered they were travelling too far. (2x too far). I changed steps per mm from 80,80,400, 415 to 40,40,200,210 and it seems to work but is only a mask IMO. I am using TMC2208 V2.1 but have ordered v3.0 to use UART without extra wires. That might have worked with the V2.1's but I read about the firmware changes required after ordering the V3.0's - Oh well, we'll see
However, it loses an entire star for the extremely poor and missing factory documentation. Almost everything has to be gleaned from other online sources - when you can even find it!
Lastly, the bed power output labels for positive and negative lines are reversed. Check yours with a multimeter before you trust it.
I don't want to downplay the potential of this board. It has a seriously impressive list of features. Maybe in a few years, this comment will be obsolete, but someone who actually knows what they're doing needs to pick this board up and create a comprehensive internet guide and the company has some interesting bugs it needs to work out. (like, i don't know, maybe having a breaker trip when you plug in the stepper drivers backwards instead of frying the entire board?)
If you know what you're doing, I think you have a shot at making this board work really well, but if you're new to anything Marlin or 3D printers like I am, this board is not for you.
I have external drivers (TB6600) wired to the 'step' and 'dir' outputs of the board driver headers. Only problem I have had it the lack of PWM pins. It seems that the only one I've found that is not already in use is on the External_2 headers. (The laser was working great).. For some reason the PWM on this pin has vanished.
Needs better 'shorted' output protection on the Fan ports.
Needs more PWM pins.
That said, the hardware is fantastic and the board's support for UART made TMC2209 Installation super easy. Love the screw terminals as well.
