   I need to update my old cnc router I built a few years ago. its using some cheap indian servo drives (loose steps at direction changes) and a bitsensor usb motion controller (not as bad as some people claim).
     I would like new drives and controller. However Ive been out of the "scene" for a good few years and obviously there is a lot of new products ,and previous products no longer available.
    I am not a millionare! so guys, what would you advise? (im in the UK). Previosly I have used gecko 320/340 and cncdrive DG4S-16035. both still available but probably dated now. I have also used cncdrive uc300 usb & ethernet motion controllers.
   I have played with hybrid stepper set ups but again they dont seem to change direction properly and loose steps. The power needs to be around 150watts and rpm around 3k
What would be your go to? should I update to brushless or ac servos?
thanks in advance

General Mach Discussion / MPG issue
« on: March 28, 2021, 09:36:57 AM »
I am trying to get the 1x 10x 100x to work with the velocity of of an MPG on a uc300
I have set in hot keys triggers 1 2 3
I have tried associating jog increment 191 192 193,  and also tried step value 265 266 267  and it makes no difference at the wheel
The port monitor is showing the pins are changing at the selection via a rotary switch on the pendant.
and the axis change rotary switch is working.
  Any Ideas??

General Mach Discussion / anilam 3000 retro fit?
« on: March 03, 2018, 08:23:47 AM »
I have a retrofit to do on an anilam 3000 controlled machine.
the drives and motors are fine ,but I believe the system is 0-10v.
what are the options of interfacing to mach3?
if possible id like to use a uc300 as the primary motion controller but thats not set in stone.
