INFORMATION NEEDED TO PROCEED WITH ORDER FULFILLMENT:

  • After placing your order please provide the stepper motor model number from either the X, Y, or Z motors and also the extruder stepper motor model number. You may send this information via the contact us page or reply to your order confirmation email. Please be sure to include the order number using the contact us page or if sending an email that is not a reply to the order confirmation.
  • The stepper motor model number is required to proceed with your order. There have been some recent changes to the Mini Delta motors. The Mini Delta has started using stepper motors with a phase resistance of ~2 Ohms. From the beginning and up until sometime in the first half of 2019 the Mini Delta has been shipping with stepper motors with a phase resistance of ~10 Ohms. Most users will have the 10 Ohm motors but confirmation is still needed to be sure that you are sent a board that is configured for your Mini Delta.

NOTES:

  • If mainboards with the original 4988 stepper drivers are in stock and should ship within 1 - 3 days after ordering (assuming the customer has sent the requested information to GigDigit).
  • Mainboards with TMC2208 stepper drivers are being made available to order prior to them being ready to ship due to many customers requesting this option. There is often a delay in shipping this version of the mainboard out but if they are available for purchase then it means there are boards in stock but may need to be modified and tested before shipping. 
  • The stock mainboard now comes with four HR4988 stepper drivers. Each stock mainboard has at minimum one test print ran with it to verify all is working. Most often the board is not tested until after ordered to ensure that it indeed was tested and working just before being sent to the customer.
  • Each "quiet" board is a stock mainboard modified by hand to remove the four HR4988 stepper drivers and replace with four Trinamic TMC2208 stepper drivers. Also each stepper driver circuit will have the charge pump capacitor swapped as is recommended by Trinamic. Each quiet board has three to five print test ran totaling between 15 and 25 hours of actual print time.
  • It is not recommended to run the printer without a bottom fan to cool the motors and electronics. This applies for both the stock boards and the quiet boards. Printing without a fan may lead to failed prints due to overheating stepper drivers.
  • If you order additional items with the mainboard please know that they will not be shipped until your mainboard is shipped. If you would like those items right away please order those items separately. 

"QUIET" OPTION

Here is a Google Photos album with videos and a couple pictures that show off the TMC stepper drivers.

Basically it will make the printer much quieter when printing. The fans will be the loudest part of the machine and then maybe a little bearing noise but that will vary from printer to printer.

I will not claim that swapping the stock A4988 stepper drivers with TMC2208 stepper drivers will make prints come out better or print faster. I will say that this upgrade will make the printer much quieter without loss of quality or speed. No firmware modifications are needed. No hardware changes have to be made by the user to accommodate the upgraded drivers. As far as the user is concerned all is the same in regards to hooking up the board and printing with the same slicer settings as used before.

NOTE: The TMC2208 drivers are running in "legacy mode". The TMC2208 will interpolate received step signals to 256 microsteps. UART is not available in legacy mode.
