SKR V1.4 Control Board CPU 32 Bit Upgrade from SKR V1.3 for DIY 3D Printer

Finally made the jump to a 32bit board. SKR 1.4 is well built and has some really nice simple features included like color coded stepper sockets. The footprint of the board is very efficient and a nice size. If you are making the jump to 32bit, make sure you know what it entails- I wouldn't call it complicated, but it is different to program the firmware to the board- really mostly just a new programming tool. One not about the board is that of all the fan headers only one has control, the rest are wired to DCv. Great product, would easily but again

a new project that allows a rpi4 to use spi to talk to this board and drive a full cnc machine has been released and it works great.

I have purchased five mainboards from BigTreeTech. All but one have failed!With my first board (BTT SKR 1.3) I decided to use a different brand for my motor drivers and thought this could have caused the failure in it. I was wrong! The solder has broken loose from the SD card slot and wouldn't allow the board to see the SD card.The second board (BTT SKR 1.4) came out of the box DOA. The replacement board worked fine for a bit and then failed to write to eeprom.My third board (BTT SKR 1.4 Turbo) worked well until I decided to install the BigTreTech smart filament runout sensor. After flashing the SD card with the new Marlin firmware, the board wouldn't see that it was attached to my printer hence the header to my review. The only changes I made to the firmware were to turn on the sensor.The fourth board (BTT SKR 1.4 Turbo) is working but has overheated two of the BigTreeTech TMC 2209 drivers I had installed. I have lowered voltages in Marlin and kept a close eye on temps but the drivers keep running hot.The fifth board is a BTT SKR 1.4 and I have not installed it. I am sure it will have issues as these are cheaply made circuit boards. I have also had one BTT TFT35 V2.0 touchscreen to fail.I have purchased a LOT of BigTreeTechs parts but no more! After five failures in less than a year, I have had my fill of their products.Each time I contacting BigTreeTech, they would go down a checklist of diagnostic procedures but none of the boards that failed ever worked again. Don't waste your money. If you want quality prints, get a good name 32-bit board. You may spend three times the amount of one of these boards but trust me it is worth it.I have been building 3d Printers for three years now. I do flash some of them with other firmware besides Marlin but Marlin is the best, for these low budget printers. I used Marlin on all of these BTT boards. I also do some coding, micro-soldering, circuit board repair, and cell phone repair, so I truly don't think these failures are from my work.

Great board many nice features over the previous 1.3. Though big tree tech has horrible tech support and did not honor there warranty or even try to contact me after I contacted them about a dead board within warranty. If you buy this expect no help or honor from them. Quality products horrible customer service.

Works good except I can't print from the sd card. The work around for me was using octoprint to load files remotely and it works great and I can still control the print from the printer(kinda)

Fan issue with Fan0 PWM. I hade dual 5015 winsinn quiet fans wired in parallel and eventually the fan0 and controller part shorted/let magic smoke out with a flash.The support for BBT seems to think it was a short in fan or overcurrent from fans. I do not see the current limit anywhere for that pin, but it appears Fan0 mosfet has known issues.With all this said its still good value for the money, just be careful with everything.

I'd love to say that the SKR version 1.4 is a good motherboard to upgrade to 32 bit 3D printing capabilities. unfortunately I've had a plethora of problems while working with these main boards including confusing driver support pages. LCD support issues with supported LCDs, stepper driver pins being shorted on arrival. I'm on my second board and I'm pretty sure I don't think this company will actually reply to my review but I will wait one week to see if they can actually give the support that a reputable business would give with this review. I really don't think it's a bad main board even after getting two fauly boards I just haven't had an opportunity to testing main boards in full with my 3D printing machine that I am trying to convert to core XYZ do to them both being defective.

i like the board and want the thing to work, i have a 1.3 in a delta and works great, but the 1.4 is just junk despite it has the extra pins on it, the com port worked at first and just stopped after a few days and the lcd screen went black and the bigtreetech mini ups failed to work, not the fqault of the ups, bigtreetech eigther ignore my messages or they come up with some bs answers then fail to help
