The smallest rail in the BOM allows the tool head to travel left and right.
Required Modification
Trim off one hole. Suggested to use a Dremel & cutoff wheel or a hacksaw. The rail will wind up around 230mm. Don’t cut too close to the holes! You’ll expose too much of the rail and it will scrape the belt!
Product Details
Don’t lose the balls!
Rails are not pre-lubricated from the factory. Any factory oil prevents corrosion. I highly recommend wiping off the oils with alcohol, and lubricating with Teflon or lithium grease for optimal performance.
