BIGTREETECH Direct SKR V1.4 Turbo Control Board 32Bit 3D Printer motherboard with LPC1769 120MHz Compatible with TFT Touchscreen 12864 Graphic Display Supports TMC2209 TMC2208 TMC2226 3D Printer Parts

This is hands down the best upgrade I've made to my delta printer. I was use an old Atmega 2560 and Ramps combo before and this blows it out of the water. My first board failed after a few prints, but the replacement that they sent me next day has been nothing but bliss. For $30 this is by far this is one of the lease expensive and best upgrades you can do for your printer. I've never had layers that were so smooth that I could hardly see them at .15.

After years of using a RAMPS board (and having replaced it a few times due to shoddy components, this is a huge improvement in performance. and quality. This along with the the TFT screen is a great and inexpensive improvement to just about any 3D printer, IMHO.

Both of the boards failed . just after the return window expired . I have had about 10 of these cards fail in under a yr . I would stay away . hopefully the version 2 lasts longer ..

Update. BIGTREETECH did get InTouch with me and solved my problem. So now I will say "I will buy from them again. I have 2 more 3d printers I want to update using the SKR1.4 turbo and the tcm2209 drivers. 5 Stars to BIGTREETECH now.. June 3 2020 -- No contact from BIGTREETECH so far. So they either don't read the reviews or they don't back up their product.. So I am saying do not buy from BIGTREETECH products. The board a 3 of the new TMC2209 V1.2 Stepper Motor Drivers went up in SMOKE. I spent hours watching videos and reading everything I could find on how to set everything up the correct way. Made a first print with no problems, Must say the first print was great. The next was not good at all, after about two min of print time things went very bad I mean very , very bad. The SKR 1.4 turbo board and the X and Z drivers started to smoke and even caught on fire. I was able to get is shut down and got the fire out fast. Needless to say, no more printing now. Don't know if is was a bad board or bad drivers.. But I do know I am out the cost of the board and drivers.. Hope BIGTREETECH will stand by their products.

I purchased this card as a performance upgrade from the SKRv1.3 but ran into a bit of a problem. My printer promptly started having issues homing the Y axis, causing the board to shut down with an error. To fix this problem, simply solder a 100nF capacitor between the legs of the endstop switch as described in the Endstops section of the Marlin documentation. This will reduce the noise preventing the endstop from glitching. Other than the now-fixed endstop issue, the board appears to be quite stable, running on all TMC2208 drivers, StealthChop on X/Y/Z and SpreadCycle on E0/E1 for compatibility with Marlin Linear Advance.

These boards take a little bit to setup and configure. I needed to re-wire my printer but the board and stepper driver combo I went with (tmc2209) was worth every penny. So quiet, smooth and I'm able to run Marlin 2.0. My other board was 8 bit and I might have been able to get Marlin 2.0 to run but for a $75 investment in my 3D printer (that I use everyday) it was so worth it. My prints are coming out great! I would recommend this board to others.

Only boards I will ever use in my 3d printers. Works great and support is quick and these boards are wide spread so community support is also strong.

Did not know till after installing and configuring this board with Marlin firmware that the MSD card reader doesn't work. It will work flashing the firmware to the eeprom but that is it. Have to your pc and a usb cable to run the gcode.
