MiniMonster's bigger meaner brother progress.

This machine already exists, but I need to modify it and repair some flood damaged parts. *finally* all the parts seem to have come my way to get it back going.

I am going to use the sanyo denki servo sets I originally bought for my brother machine. They run on either analogue or step and direction. I already have a mesa 7i77 for analogue use.

Does anyone have any opinions on whether I should stick with that, or move it to step and direction. There are a number of benifits to going with analogue, but my last experience tuning analogue servos on linuxcnc went poorly. These are very different drives this time though on a very different machine.

Drives are sanyo RS1, and the motors are sanyo P5 with 2000 line encoders.


 
 
 
 
 
 

I updated from LinuxCNC 2.9.2 to 2.9.3 along with latest version of Probe Basic yesterday.

Everything went smoothly and I decided to attach a camera to the mill so that I could record some milling.



Overall the macine works great but I really need to upgrade the BT40 spindle so I that can run at higher rpm's. It would significantly cut down the maching time if I could run 6000-10000 rpm instead of the ~3000 rpm I'm currently limited too.

Did you have a look at this?

linuxcnc.org/docs/html/examples/mpg.html

This gave me the basic idea, and then I could change the *.hal according to the requirements.
To me it looks that this wireless thing just connects to the machine like a normal wired device.

I am not using an "official encoder input" for the MPG just normal inputs were doing the job, So I did not change the bitfile on Mesa card plug and go kit.
