MAch3 PMDX126, PMDX107 Spindle problems
« on: August 07, 2014, 09:13:09 PM »
Milltronics Partner Four Milling Machine Conversion
Mach 3 ver 3.042.040
pmdx 126 bob
pmdx 107 Spindle controller board
USB Smooth Stepper USB ,driver ver V17fe
Windows 7 Enterprise 64 bit OS
HP Compaq Elite 8300 SFF

All Axis and Saftey Switches Work Perfect
Have cut acurate Parts turning Spindle on at VFD
Coolant Pump Works , Coolant Relay K1 Pin 1 Port 1 Output
Mach 3 Spindle Motor outputs settings are
Enabled Checked Green
Step pin 16
Dir pin 14
Dir Low Active Checked Green
Step Port 1
Dirport 1

spindle starts from m03 in program
m05 does not work to stop spindle
Spindle  button does not work in Mach3 till after run program once
then will turn on any time
Can not adjust Spindle speed with the S Command or any of the buttons in  Mach 3
VFD is a Rockwell Powerflex 4 FRN.xx model
P36 Start Source is 2 = 2 wire
P38 Speed Ref is 2 = 0-10 volt input
Constant 0.473 volts at the PMDX 107 Board 0-10volt out puts and at VFD Inputs Voltage never change
on the PMDX126 and 107 board set to work with no charge pump
Does not respond otherwise.
Run Test Function on PMDX 107 Spindle Board and Spindle runs at full and then 1/3 speed as it is suppose to
HAve 10 Volts on test and 3.31 at 1/3 speed
So The 107 board is hooked up right.
Originally had 2 parallel cards and never got it to work with them either
so Got a Smooth stepper Instead
Any Sugestions?
Email me if you need any more Info
Thanks for any help

Well after some exhaustive research ,I found out it was the ver of mach 3 I was using  I had ver 3.042.040
I now have 3.043.062 and everything started to work right away.
I Have been at this project on and off for a year
and feels good to finally see it come together and work
Thanks to all who have read and helped on this
the Folks at PMDX, Viper Servo Drives ,Warp9 smooth stepper, have reliable and dependable products
Hats off to all of them
