CAMBAM ENGRAVE 3D PROFILE FREE
The clearance plane should be clear of the stock and any holding devices to allow free movement to any location. The clearance plane (offset from the work plane). Lead in moves and holding tabs are supported. Other uses include facing edges and with increased cut widths can be used to create pockets.Ĭuts can be inside or outside a selected shape. Profile Machining OperationĪ 2.5D Profile machining operation is typically used to cut out shapes. If you've used CamBam before to drive a CNC mill, the only thing to remember is the spindle speed to laser PWM mapping, and to do cutting speed tests with your choice of materials.Documentation for the latest CamBam release is available here.
CAMBAM ENGRAVE 3D PROFILE HOW TO
We're currently producing useful docs on how to drive it based on training we do with people who want to use it. You can find our post-processor on github at: įWIW: CamBam's spindle speed maps directly to the PWM for the laser, with a range of 0-255 (0 = 0%, 255 = 100%). We use CamBam to produce the necessary G-code with an appropriate post-processor. You can find our copy of the Hardware and Firmware (a modified version of Marlin) up on github at: While the board has similar pinouts for motors as RAMPS does, some connections will definitely be different, so check the Marlin config & the schematic of the board in detail if you want to use a RAMPS board with that firmware. The board is an all-in-one design that talks to external stepper drivers, as they were already in the machine. We wanted something generically cross platform (ie: talks G-code) and open source. Specifically, we use Marlin on a similar board to RAMPS (uses same motor pinouts) in an old Redsail laser cutter that the original electronics died on. The hackerspace I'm involved with ( Connected Community HackerSpace - or CCHS) is using Marlin to control the hackerspace laser cutter.
