Successful CNC induction

A big thanks to @Julia for the induction yesterday, it was a lot of fun and arguably very successful. What was meant to take 45 mins ended up being closer to two hours.

The reason for this is simply that “things went wrong”, which for a newbie is great because we get to learn how to troubleshoot and solve problems (and how to use the emergency stop button quickly…)

We found a nice sized bit of hardwood for the induction, I measured it for the tool and followed all the instructions to safely use the machine.

First emergency stop button use was due to a number of things:

  • the clamp failed and the stock lifted up
  • the stock was not particularly square
  • the stock had a bow in the middle and was not flat
  • tool 22 (2 flutes) potentially wasn’t sharp enough for the wood

Because I was so excited I was filming the whole ordeal, arguably my hand should have been on the E-stop.

I cleaned it all out, checked the bit, and flipped the stock over and tried again. Second time was better, but we had adjusted the cut depth to be kinder on the tool. I also had some Z axis alignment issues, so we tried a third time with a bit of ply.

This worked much better, used tool 23 rather than 22 and I noticed as it was cutting that again this wood wasn’t flat, instead it was slightly high at 0,0,0 and low at the other corner…

Nevermind, had a lot of fun and my scrap bit of monogrammed wood looks cool. Would recommend CNC engraving ply!

it is always great when things go wrong while learning and you have someone there who knows and can help!

sounds like a great induction

Nice work! Yes, will be recommending tool 18 and 23 for the next inductions!

Will try to order some new tool 22s…

Cheers!
