- Document your work to the group work page and reflect on your individual page what you learned
Maslow 4.1¶
We chose Maslow 4.1 as our large (4’x8’) CNC milling machine. It’s affordable and will not take large floor space. It’s a CNC milling that uses four independently controlled belts to control its position while cutting. So we need to place four anchors around the workspace. There are option to fix anchors, one is to drill a floor and put bolts, the other one is making a frame. We chose to make a wooden frame.
There are drawing for suggested wooden frame from vendor. https://www.maslowcnc.com/wooden-frame
Yoshi built the machine.
Bara cut wood parts.
And we built a frame.
Test runout¶
Maslow is hosting online CAM tool named MakerCAM for free. So I draw a circle on MakerCAM and setup parameter as below.
We screw fastened offcuts (t=12mm plywood board) to a spoil board (also t=12mm 910x1820 mm plywood board) and run a test.
It works!!
We tried CrabzCAM, too. I personally like CrabzCAM more than MakerCAM. I opened a SVG file with CrabzCAM, and setup parameter was as below.
It also works!
Consumables¶
Here is the list of consumables.
The router using with Maslow 4.1 is DEWALT DWP611, and it has 1/4 inch shank collet.
