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 find 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 stepper drivers, we suggest you install all the headers & connectors and only populate those you required.

Where to buy this upgrade?

You can purchase this PCB with optional components in our Tindie Store (Subject to availability)

Prerequisites

• Soldering - You must possess the training, skills and equipment required for soldering.
• Components - If you have not purchased the components, they you should source your own based on the BoM below.
• TinyG V8 controller Board - obviously you will need a TinyG to complete the upgrade.
• Your own TMC2209s from BigTreeTech v1.2

Bill of Materials

• 1 x PCB (100x80mm)
• 7 x 4P Screw terminals
• 2 x 3P Screw Terminals
• 2 x Jumpers
• 6 x Male Headers (4 extra long)
• 12 x Female Headers
• 2 x 0805 LEDs (pre-soldered)
• 2 x 0805 resistors (for LEDs) (pre-soldered)
• 4 x TH capacitors (KEMET, 100uF 35V 105degC)
• 2 x STD30NF06LT4 (STMicroelectronics N-Channel MOSFET)

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.

Differences for OpenPNP - The only difference is the position of the jumpers on
