Almost finished my MP3DP v2 build. Just waiting on a thermistor for the heated bed, but otherwise complete. In the meantime, it’s printing PLA well on masking tape on a cold bed.
I used a SKR Pro 1.4 with TMC2209 and a FYSETC mini 12864 display. A few photos starting with the frame cuts on the MPCNC:
The first print just stopped - I think it may have been a bad connection or related to the power supply. The second print of the calibration cube finished. Third print is the first iteration of a mounting bracket for the SKR board. Fourth print was a test of vase mode.
I initially started with Marlin-bugfix-2.0.x and then made necessary changes. I compared to firmware in the V1 firmware for MP3DP_Ramps_16T to find key code changes needed for the printer. I also followed a couple YouTube videos to get the key code changes needed for the SKR board: https://www.youtube.com/watch?v=oHMZ0ocTYvM and https://www.youtube.com/watch?v=-Gdk0wHg51w
The most difficult part was getting the display to work properly. I did need to flip around the notched connectors on the Fystec Mini 12864 panel; and I eventually found the needed code changes for Marline online. This page was the most helpful: https://wiki.fysetc.com/Manual_for_Mini_panel_on_SKR/
After running with Marlin for a while, I wanted to migrate to klipper as I got used to some of the features after getting klipper working on MonoPrice Maker Select v2 (Wanhao i3 Duplicator clone). I have been running klipper since.
If you have any specific questions, I would be happy to try to help. I can also post code, though I am quite unfamiliar with github, but perhaps it is time to learn.
I’m running pretty much the same setup except with the BTT TFT24 for the control screen. Such a huge difference switching from the old RAMPS to the SKR board. Stealthchop off for speed, and on for quiet. So much nicer.
While I am passed the 50, I don’t notice much of the noise, my kids though are constantly complaining about high pitched noise the I turn my deltaprinter on (Ramps 1.6). That is the reason why I bought 2 SKR boards with TMC2209’s.
My printer with the SKR / 2209 is near silent. Movement along the Y axis moving the bed is most noticeable sound, but really isn’t loud at all. I also ordered a Sunon “MagLev” fan to replace the stock MK8 extruder fan, and it is so quiet, I need to actually check to confirm it is running.
Those fans look great, do you have the model number of the one you bought? They have so many options. I think a 40x40x20 would have a little more power to work as a print fan than the inexpensive ones I have. Printing faster is requiring a little more cooling than I have, and to quiet it down at the same time is a bonus.
I opted to heat up the solder on the diag pin and quickly pull it up with pliers. I didn’t pull it all the way out, just up so it doesn’t insert. Really quick and easy, and my thinking is that is that I can move the pin back in place in the future if I wish.
