Title: Overcoming Unexpected Challenges and Taking First Steps with My Setup

Hello everyone!

I think I finally did it! It wasn’t easy, and I ran into some strange and specific issues along the way:

  • The TFT display refused to update with a particular board that had been working fine just before (still a mystery to me).
  • A defective SKR 1.2 Pro board that wasn’t detecting the endstops.

Since the last time I wrote, I’ve also installed the new board, which started up flawlessly, attached the touch plate, checked the squaring, and printed my first ring… although, unfortunately, the pen holder is a bit too flexible, which causes the pen to wobble.

What do you think? Should I run the test again? How does it look to you?

Now I need to start working with the milling tool, but I have a few questions. How can I determine the rotation speed given that my tool is similar to a Makita router and doesn’t have a tachometer? Do you have any tips for testing with different materials?

As usual: GRAZIE!!

It looks pretty good. It is a little wobbly. But it is probably in the paper or pen holding. You can move on to creating your own gcode files for the test crown using estlcam and if that works, you can move towards making it dirty with a router.

Congratulations! That is a great accomplishment. :tada: :crown:

similar to a Makita router and doesn’t have a tachometer?

If your router is a Makita clone, then it is likely that your RPM values will be close to the ones on the Makita. If not, you can purchase a tachometer for under $20USD and test your router.

For my Makita clone (purchased from Carbide 3D) my tested RPM values are:

Note the measured values vary a bit from the one specified by Carbide 3D, but not enough to make a significant difference in milling. The spec values are:
