Re: Single to Quad converter

I believe that the differential levels normally range between approximately .5 V to around 2.5V (or more),
not necessarily 0V to 5V like is commonly assumed. Are you using a scope or just a meter ?

Re: Velocity or (Torque?) Voltage Mode?

Velocity Mode is the short answer. The two most common methods of commanding servo drives are Velocity Mode and Torque mode. Please see previous post: http://www.ajaxcnc.com/ajaxbb/viewtopic.php?f=20&t=109&p=532&hilit=velocity+mode#p532 Re: Tuning Servos Postby CNCguy » Thu Jul 15, 2010 7:37 am Use ...

Re: 8 possition turret

The short answer is yes, Ajax can drive a turret similar to what you describe.
I only know that lathe turret PLC programs have been successful for the Ajax MPU11 running Centroid software ,
but you appear to want to use Mach3.
Anyone else using AjaxMPU11 lathes with Mach3?

Re: Cutter comp problems

Are you running Mach or Centroid software?
Can you post a short section of your program , narrowed down to a few lines before and after the offending G-codes?
