This is due mainly to far more aggressive DOCs though and failure to clear chips fast enough.Even with liberal amounts of cutting fluid, the bit broke within two seconds.I believe its trying to plunge in too deep before starting the cut process, as the Y axis started to struggle and skip after maybe an inch or two.
![]() ![]() I mill complex parts for 3d printers and other things in 18 to 14 6061 and aluminum tool plate. Cnc Router Feeds And Speeds For Cutting 2.5Mm Thick Aluminum Mods Needed OnGetting good results off the X carve is not hard to do in aluminum but does take attention to how it is done and some mods needed on the X carve help greatly. What are you using for CAM Are you on the stock X Carve with the stock controller card Have you tried using Chilipeppr yet. Q: have you done any stiffing mods to the gantry, if so; what method A. I was using the Easel software, and I was under the impression that it calculated all the feed rates for you. The deep luster of the wood and shiny finish of the aluminum balance each other nicely for a finished object that works well and looks good. Im open to any suggestions for a good strong bit, and manual RPM and feed rates. Acme Z Axis, NEMA 17, Full metal slotted bed, TinyG going through Chilipeppr. No real mods other than limit switches and large 3D printed spindle mount VS the stock mount. Cnc Router Feeds And Speeds For Cutting 2.5Mm Thick Aluminum Drivers And ICurrently the Shapoko has two changes, I now run a PLanet CNC MK34 controller with Leadshine DSP drivers and I switched the X Carve spindle mount over to the Shapeoko and it has been a good improvement. Cnc Router Feeds And Speeds For Cutting 2.5Mm Thick Aluminum Code Senderinterface ForMy current system has a proprietary gcode senderinterface for the Planet CNC controllers. It is basically a cross between Chilipeppr and MACH3 overall. So I design my parts in CAD, use HSMxpress for CAM then send the Gcode to the controller with the CNC USB controller software interface from Planet CNC. I use a 116 2 flute flat end mill from Drillbits unlimited ( ) I also use a 2.5mm 18 shank drill bit for the M3 tap holes. Drillman1 or Drillbitsunlimited. Part one for the OKO with the DC spindle: There is not near enough power to remotely use a calculator with a DC spindle on the OKO or the X Carve. Milling aluminum on the stock DC or an upgraded DC spindle on the X Carve or the OKO is NOT a fast process and is closer to scratching than true milling of aluminum. The OKO and DC spindle with the 3mm Destiny 3 flute end mill did a DOC of.12mm and feedrate of about 135mmM for the shots you see above. The 116th 2 flute endmill ran about.1mm DOC and around 75mmM. ![]() It was subject to a great deal of flex if pushed too hard and would break end mills. I am using the Gwizard calculator and it is a great tool by all means, but still manages to break end mills.
