TMC2209 TinyG upgrade assembly instructions

WIP WIP WIP WIP WIP WIP WIP WIP WIP WIP WIP WIP WIP WIP WIP WIP WIP WIP

Here you can fing the instruction for assembling your TMC2209 TinyG upgrade for LitePlacer, OpenPNP and other TinyG systems

The instructions assume you are installing headers for all 4 motors, which is recommended. However, if you only want to upgrade2 or 3 steper drivers, we suggest you install all the headers & connectors and only popullate those you required.

Where to buy this upgrade?

Pre-requisites

  • soldering
  • Components
  • TinyG V8 controller Board
  • Your own TMC2209s from Bigtreetech v1.2

Bill of Materials


Steps

  1. Take a photo of your existing wiring and label your wired goinf to the TinyG
  2. Remove the TinyG from your system, so you can work on it.
  3. At this point turn the POTs on the stepper drivers you will be upgrading to the lowest setting (refer to TinyG or LP docs).DO NOT FORGET THIS STEP!
  4. Note: all components are soldered to the top of the PCB (except the 4 long male headers)
  5. Solder the 4 female headers to the TinyG PCB (3x4P + 1x5P) and put the TinyG aside for now.
  6. Solder the 2 Mosfets (Pre-installed if components ordered) [Q1, Q2]
  7. Solder the 2 resistors (Pre-installed if components ordered) [R2 4K7, R1 56K]
  8. Solder the 2 LEDs (Pre-installed if components ordered) (0805 Red LED) [D1, D2]
  9. Solder the 7 Screw terminal Blocks (7x4P) [J19, J17a, J17, J15, J11, J7, J3]
  10. Solder the 2 Screw terminal Blocks (2x3P) [J12, J9]
  11. Solder the 2 short male headers (2x4P) [J18, J20]
  12. Solder the 8 female headers to accept the upgraded stepper drivers. (8x8P) [J1x2, J4x2, J5x2, J8x2]
  13. Solder the 4 Capacitors provided [C1, C2, C3, C4). Note weprovide TH caps, but there is also a footprint for SMD caps. Make 100% certain that you identify te GND pad before soldering.
  14. Solder the 4 long male headers to the underside of the PCB. (3x4P + 1x5P) [J2, J6, J10 + J14]]
  15. Now insert the PCB into the TinyG board with care, to ensure a good fit. The PCB must be higher than any component on the TinyG.
  16. Insert he jumpers into J18 & J20. The position for LitePlacer and OpenPNP are marked on the PCB. Make sure not to jumper the 3V3 or GND pins. Make sure you are happy with the connections for Z-max & Z-min by checking the connections on J19 with you DMM.
  17. Before proceeding check all solder joints are good/acceptable.
