Hi my name is Valerio and I am new to LinuxCNC.
I like to play with CNC machines.
I am in the middle of designing a 7 axis machine.
This machine has 4 axis that move X,YY,Z (I have 2 stepper to move Y) plus another 3 axis, 2 of them rotating the spindle and the third one rotating a lathe chunk (as you can see from the pic).

I use to use Mach3 on another machine that has 4 axis X,YY,Z but for the new machine I cannot use it because Mach cannot control more than 6 axis.
I saw that linuxCNC allow you to customize different kinematics and allow you to control up to 9 axis so my questions are:
1--I will be able to control my machine with linuxCNC?
2--If answer 1-- is yes; How I can slave one of the Y axis to synchronize motion on Y and generally how I can customize linuxCNC for my DIY machine?

Thank you in advance for any tip.

Regards,
V.

What controller or how is the PC connected to the machine ?
LinuxCNC can control that easily, but setting up and tuning such a machine might be a bit more complicated, although not always.

Hi
Thanks for your answer.

The machine is not on its feet yet, so the controller at this stage has not been chosen.
I use a laptop with dual boot windows10/linuxcnc.
I am just trying to think ahead.
At the moment on my other machine I use a an UC100 usb connector to match a parallel port shield controller but, I am pretty sure that I cannot use the same system for the new machine.
So I need to get more into this topic.
Anyway thanks again for your help.
V.

Laptops in general are not good for machine control, although i did find some used Fujitsu that do work nicely.
Since you have no controller, do have a look at Mesa boards, they are very nice and versatile and configurable and have the best tech support on earth provided by PCW, the owner and also a very active member of this forum.

If Mesa 7i76 (5 axis control) is used with parallel port, can we put another 2 axes to parallel port?
