Using the step blocks, set the gantry roughly equal on each side to square up the machine. I used 2-sided scotch tape to secure the part. I might also be able to modify the smoothie post processor to add this in. I might be able to ignore this if I follow the correct steps below… but do it until I learn better. This will raise the bit to a safe height from the start. (needed?) Open the file by hand like a cave man and add “G1 Z5” to the code JUST BEFORE the first G0 or G1 command. We’ll be using printrun (does anything else work for smoothieboard?) which only looks for. I used 1/8″ as my term and easily found something that would work.Įxport the CAM using smoothieboard CAM process. The menu seems to have changed since I last saw it. In the first 2D contour settings tab, you must select the tool. I set clearance heights at 5mm, 10mm is safer but slower. Multiple passes, no more than 1/2 bit thickness each with triangular tabs. Add a tab or so to the inner parts to prevent them flopping around or going ballistic. Make sure to select all the inner contours as well. Set up a 2D contour and select the bottom of the design to be cut out. Set CAM origin to nearest-leftist-top face of project stock (0,0,0)-ish on my machine Realize that my machines is Left hand rule orthoganal axes. This can likely be fixed by creating my own tools file locally with these values hard-coded as defaults. I used easel to get the settings I would use for feeds and speeds, then converted them to mm. She used photoshop and MakeTheCut (for our Zing vinyl cutter) to generate the SVG. CAM is tough though, especially when using mm.įirst I had Jess (Queen of fonts) find a cursive font that connected most of the letters together and had her create a SVG file for me of it. Below are notes to myself on the workflow.ĭesigning a sign in Fusion 360, simple enough. After a few failed attempts at PCBs (I’ll post what I learned there some other time) I thought I’d work on something on the macro scale. So I just got back into fighting working with my CNC machine.
