Watch cables for motors and z-axis. If cable lean on heat sink, even slight but constant push will cause glue to yield and heat sink to fell off. It happen to me! I am illustrating correct cable mount. It is probably good idea to redesign future releases with connectors on side or not so close to heat sink ![IMG_5896](https://canada1.discourse-cdn.com/flex031/uploads/maslowcnc/original/2X/5/5cc74b74f1c67c22cfa3623af1249cdfb2c8c552.jpg) ---

I’ve noticed this before too. I’ve just recently glued mine on with this stuff. > **[GENNEL 10gram Thermal Conductive Glue Silicone Plaster Viscous Adhesive Cooling Compound For LED GPU Chipset Heatsink: Amazon.com: Industrial & Scientific](https://www.amazon.com/gp/product/B072MSXHJD/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1)** Also reorganizing my cables so they don’t push on the heatsinks. ---

You might want to look at this thread: > [@Better heat sink design?](https://forums.maslowcnc.com/t/better-heat-sink-design/86): > > I found my heatsinks were falling off. I plan to adhere them with a heatsink plaster/glue to hold them on better. That said I felt the chips while it was running the calibration and they were just warm. I’m wondering how important the heat sinks are? Also for future revision of the maslow boards you might consider the heat sinks that solder to the PCB. I’ve found for my projects the types of heatsinks are really nice since I can get by with small heat sinks and use the ground plane to help. … Thank you ---

I’ve decided to disign this maslow-arduino-case with two fans to refrigerate the heatsinks. ![WP_20180503_22_52_10_Pro](https://canada1.discourse-cdn.com/flex031/uploads/maslowcnc/original/2X/9/98d287f3c6b2cf56ab36e4a85cb177a8adb290c7.jpg) ![WP_20180503_22_53_58_Pro](https://canada1.discourse-cdn.com/flex031/uploads/maslowcnc/original/2X/1/1d9535d7e58bd2e26abf0d78def557828d2a591a.jpg) In my opinión the solution to prevent the fall off is to position the case in the horizontal position, because of gravity is the best option to prevent this. ---

Very cool! (Pun intended). I have a CO2 laser and about a thousand sheets of cast acrylic just itching for such a project. Care to share the design with the community? ---
