I made a camel thing

[rlrcstr]

• 4 layers
• Designed in Corel Draw
• Extruded and exported to gcode from Fusion 360
• Cut with a .5mm flat end mill to allow for the detail
  Slowly, over many hours
  5 broken bits
  Could not get the laser to cut, consistently and it didn’t seem that it would be much faster, anyway
• Camel is cut from 1/8th inch basswood ply
• The backboard and frame are made from my old birch flooring
• With the frame, it’s 13.75 inches square

@rlrcstr

Thank you for sharing this impressive work.

Given that 5 bits were broken during the work, could you please tell me the work speed?

Cheers

Here is an article for your reference:

CNC Cutting with Files Exported from Fusion 360

This guide teaches you how to generate a simple CNC model with Autodesk Fusion 360, and proceed to CNC cutting with your Snapmaker. If you intend to follow this through, then you will need a cylindrical piece of material that can be CNC cut, with a minimum diameter of 85 millimeters (mm). Alternatively, you can practice modeling with this guide on Fusion 360, and design a project of your own. Happy making! 1. Configuration 1.1 Visit snapmaker, and download the Configuration Files & Tool Libr…

A tip:

When cutting out a part with a CNC cutter, you can leave a small part as an extra clamping tool to prevent the tool from hitting the model near the end of the work, which causes the CNC bits to be broken.

I tested anywhere from 150 to about 225 mm/min. I don’t think it was the speed that was the issue. I was using a half millimeter diameter bit. Very fragile, to begin with. Then cutting out some detailed bits that were too small to accommodate tabs… I spent a lot of time watching the cut and clearing the bits of wood that were cut out. But I couldn’t watch the whole time, and I think the bits broke because of the cutouts snagging the bit. I tried using repositionable adhesive under the board, but the smaller cutouts just didn’t stick.
