SKR Pro v1.1 32-bit high-Frequency 3D Printer Control Board,Support TMC5160,TMC2208,TMC2130,TFT28,TFT32,TFT35,12864lcd ect.

Have yet to print with it. Still setting things up. In particular it uses 2.54mm JST-XHP2/3/4/5 connectors which are a royal pain to crimp, are tiny to work with while trouble shooting and do not like being disconnected. So if you are not super adept at setting up a board and working with these delicate connectors, beware. Also, for the optical stops, the pull up resistor across signal and voltage was easiest to do on the optical board itself, for me. Will likely revisit this revies.

I am building a Lowrider V3 CNC from V1 Engineering and this forms part of that build. I have done the 3D printing part of the build and gathering all of the necessary parts. Whilst I haven't put everything together yet, after my initial research and inspection of this, I am very happy. I will update the review once I have completed the build.

The board is generally good quality with decent features and reasonable price. Unfortunately, some of these boards have issues with endstops not working properly. I had to solder extra pullup resistors to get the endstops to work. Other wise great product.

Let me start by saying that I'm a controls engineer in an engine CNC plant. 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 -32bit **Update** 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

Using this card with BIQU 2209 drivers and BIQU TFT35 V3.0 and it works great once you get the software sorted out. Lots of features and no extras really needed. Beware this board is large. If you have a smaller printer it may not be possible to find a control case that will work and fit on your print bed. I have this issue. The case I want won't fit on a 220 x 220 bed.
