SP6 CNC Shield V4 Modification

This is my first time working on CNC Shield and related eletronics. I want to make sure I am doing the modfication (4 edits) correctly. Do you think you can share a picture of the backside of the CNC board after the modification? For example, I am not sure how to do Edit 2, Do i just short the four nodes on the right side, and connect the Vcc on the left to the top node on the right using a wire?

Thanks a lot,

Hi Steve, i have a question about the Adruino nano board. The one I got looks slightly different from your instruction manual. It looks like this. I guess it should also work?

In your manual, the first step is to "Solder the headers onto the Arduino Nano and insert it in the orientation shown." What "headers" I need to solder before I plug it onto the CNC?

thanks,

Steve

It should work. Arduino Nanos are all supposed to be compatible with the original design, although I am not sure about some of the newer bards with wifi and a bunch of other features. Most of the boards I order have a USB-C connector which uses an easier to find cable. The clocks support both connector styles.

The headers are already soldered on the board shown. They are the bottom pins that go into sockets on the CNC Shield V4 board. Some Arduino Nanos come with them loose.

Yes, the 4 nodes in a straight line plus the diagonal node need a wire. This is my version. The two wires in the upper right are the only ones that need to be insulated. The rest are protected by the solder mask.

thanks so much, Steve. Should I do the wiring first then install the "clock_shield" or the other way?

Follow the steps in the assembly guide or SP6 addendum describing the CNC shield V4 board.

It starts with soldering the wires. Remove the jumpers under the TMC2208 location, then insert components. Plug in a USBC cable and program the Arduino Nano. Power to the stepper motor is provides through the USBC cable, so do not use the socket power connector.

Test that the board is able to rotate the stepper motor before assembling everything into the clock.
