Hi Amir
Not sure about kflop as I have never used it.

Yes might add that in once I get the machine up and running.

Hi Amir
I'm using the older 2100 series which is on Ethernet. I would recommend an econo series for a new purchase. The latest accellera is the best card if money is no object.

Another thing about mach which can be a disadvantage is the way it homes. The big machines have a slow down sensor so you can  go at full rapid speed to this then slow down to a set speed to home the machine. Handy if you have big travels. Mach doesn't work with a slow down as far as I know.

Hi Amir
I am working on a mach set up with galil and Mitsubishi servos for a small mill. Not at the powering up stage yet though.
Have used mach with steppers though and it works well.
My full size machines all have Fanuc 6. I have no experience with meldas but the industrial controls in my opinion are very robust and the software never let's you down.  In fact its as bullet proof as you can get.
Although my Fanuc controls can't cut as fast as mach without losing accuracy they are better at doing back lash comp and closing the servo loop. Same goes for the meldas I expect.

Btw those flexi couplings on your motors cost an arm and a leg if you need to change to new motors with different shaft sizes...just thought i'de mention it!

Well I can see Amirs point of view but i've found Mach to be very stable and have never had it lock up mid proramme.

I'm with Hood on moving away from the printer port. That machine will really move if you want it too plus with something like the Galil controller you would get the closed loop back similar to what the Meldas would have had.

That said you can close the loop in the drive on the modern Mitsubishi drives and they will take step and direction signals from the pp.

But as far as I know anything bigger than 1KW needs 3 phase in on the Mits!

Found these on ebay..

No problem Jh I've noticed your machine had the spindle off centre ln the head casting...the old hurcos were just like this and they were made by leadwell.
