Setting Up On A CNC Shield v4.

This is an older post about setting up a CNC Shield, but I have edited it since the title and description were misleading. The comments here are EXTREMELY HELPFUL for setting up a CNC shield v4 board. They include code for testing if your stepper motors are correctly connected, the pinout, and pin numbering for Arduino IDE.

The kit you should buy if you would like to follow this tutorial can be bought here: https://www.aliexpress.us/item/2251832035811475.html?spm=a2g0o.detail.pcDetailTopMoreOtherSeller.10.3fe9i0iWi0iW2v&gps-id=pcDetailTopMoreOtherSeller&scm=1007.40196.366991.0&scm_id=1007.40196.366991.0&scm-url=1007.40196.366991.0&pvid=5c83e78e-97fb-48de-a5c7-35db0da5b120&_t=gps-id:pcDetailTopMoreOtherSeller,scm-url:1007.40196.366991.0,pvid:5c83e78e-97fb-48de-a5c7-35db0da5b120,tpp_buckets:668%232846%238111%231996&pdp_ext_f=%7B%22order%22%3A%2210%22%2C%22eval%22%3A%221%22%2C%22sceneId%22%3A%2230050%22%7D&pdp_npi=4%40dis%21USD%2119.99%2119.99%21%21%2119.99%2119.99%21%402103010e17397411430922198e1202%2155305829959%21rec%21US%216242698492%21X&utparam-url=scene%3ApcDetailTopMoreOtherSeller%7Cquery_from%3A. This may be more expensive then the $2 "cloned" boards, but it is entirely worth it. The cloned boards have many problems that require cutting PCB and soldering to fix. To find out more about this, look up "Fix Cloned CNC Shield" and an instructable should show up. The expensive Keyestudio kits work right out of the box, and come with 3 stepper drivers. If you would like more help, please ask in the thread.

I have a couple of questions, first where do I place the 3d clippy servo on the CNC Shield v4 and what orientation do I do for it. Another question is what size of servo should I use for a modified 3d clippy, https://www.printables.com/model/778707-3dclippy-generic-filament-cutter I personally have modified it for my printer and circumstances. My last question is my Cam broke and I printed a new one and now every time I select one T0 it pulls T1. I only have 3 filaments so I don't know if T2 and T3 are also doing that. I have modified the code to help a little but it still does it.

Thanks.

Oh, make sure to reprint everything on the same print in PETG with .2 mm layer height and 100% infill. This is the kind of servo Bill recommends: https://www.amazon.com/Torque-Motors-Waterproof-Steering-Control/dp/B0DDKN9RS6/ref=slsr_d_dpds_fsdp4star_fa_xcat_cheapdynam_d_sccl_2_4/135-4448785-9319159?pd_rd_w=K5THO&content-id=amzn1.sym.189ba0e8-243a-408f-947d-77c5ac846d2e&pf_rd_p=189ba0e8-243a-408f-947d-77c5ac846d2e&pf_rd_r=8DKW5ZRK9SP2JSWR0323&pd_rd_wg=s3ftv&pd_rd_r=ba40394c-0911-475e-b176-9241d4adb27e&pd_rd_i=B073F92G2S&th=1\

Choose the 20 or 25 kg (preferably 25) with 180 degrees.

I do not know if the one you linked will work (or not work) so you choose that at your own discretion. As for a buck booster, you will need:

Buck Booster: https://www.amazon.com/dp/B081N6WWJS Power supply to wire adapter: https://www.amazon.com/Qaoquda-Connector-Terminal-Headphone-Converter/dp/B07JMY5XXT Power supply splitter: https://www.amazon.com/Splitter-Surveillance-Adapter-Y-Cable-Security/dp/B082Y1PQ6C

You will use this to split a wire of the 12v power supply, then convert the splitter to a wire terminal so you can connect it to the buck booster (which you will need to set to your servos highest voltage) which then can connect to your servo.

You will need to be careful while doing this, as I accidentally fried a cloned Arduino while attempting (due to user error). Side note for the servo: Depending on what your budget is, you could get both and see if they both work the same. My budget is very low, so I pretty much only bought the necessary components.
