Shopbot alpha 4x8.jpg

The shopbot is a wood CNC router in the woodshop. We have been teaching introductory classes to the Shopbot and CNC on roughly a monthly basis. Look at the calendar for classes. These are limited in size, and we split into 2 groups to get hands on, each covering the shopbot and one of the two software packages that's being used.

Note, that like everything in the woodshop, use of the Shopbot requires that you be authorized to use the woodshop, via the class.

Software

There are several ways to generate the g-code required for LinuxCNC to use the shopbot.

Problems

One problem that has been encountered is that due to trying to keep the feed rate up, the motion planner will cut some corners. To prevent this add the line to your program: "G64 P0.001". This will tell it to keep deviations to less than 0.001 units (mm or in), while still attempting to keep the speed up as much as possible. You can use a higher value if you want to. See here for a more complete discussion as to why that happens: http://linuxcnc.org/docs/2.6/html/common/User_Concepts.html
