Don't worry about the lack of post for me, i always plan to built a five axis cnc, but at this time i've start a cnc buisines in my country, and haven't time...
Hi I am currently a beginner when it comes to making toolpaths. Ive only just managed to figure out how to make my model in 3DS Max, however I now need to...
I am going through the tutorial for the cnc_toolkit . I see that there are 3 .gmax files provided. But as I am using 3DSmax I cannot use them. Are there...

I am working on adding a forth axis to my cnc table. It would be rotary axis parallel to the X axis. Is there a motor type, Stepper or Servo, that could both...
Yes, there are numerous ones. The limits will be the mechanical accuracy of the system, and funds. I am using such on the 7-axis cnc lathe I am retrofitting. I...
Hi Ben, The tutorial files are just available in GMAX format, I'd suggest installing GMAX for the sake of accessing these files. For your axis swaps would it...
Thanks for the good post, I'm retrofitting a small CNC lathe and hope to be able to both spin and control the chuck. I have a Gecko drive and a treadmill motor...
Thanks Hanermo . . . That's some great info, I suppose the treadmill motors are servo's? Also, I am running steppers via a CandCNC breakout/THC system & Gecko...
You can mix steppers and servos as much as you want. The control sw like mach3, wont care. The treadmill motors are std permanent magnet dc motors. When you...
Hi Is it possible to use this stepper with gear to make a B and C axis? Link: https://sdp-si.com/eStore/ go to: -Motors -Gearmotors -Stepper I was looking at...
I would say no, due to the excessive backlash in the gearbox [~45arc min.] Look for a precision planetary reducer [Ebay has them from time to time] you can get...

... Hello Rab, everyone Just to say that I've re-bundled the FREE version of the guide to resolve the problems reported by users of AVG anti-virus software. ...
Rab, it appears you have used a Sherline rotary table for your 5th axis (B), and a modified Taig lathe spindle for the 4th axis (A). Is this correct? If so,...
Hi, I felt that the Taig headstock is better for the type of work that I do. It's more compact than a rotary table so less likely for the spindle body to hit...
Hi Terje, I've looked at these before and some are perfect for this application. However, they are very expensive. Rab ... like ... their ... take ... ...

Hi, where did you post the photos ? Have you tried Mach3 for the rotary work ? I shared an algorithm with Art, the author of Mach3 which makes the rotary...
