Geckodrives vs others

[Mammoth 01]

Hi jazz,

I'm back with some info. So here is what I have set up Mach 3 is running and communicating with Ess and PMDX 126. I have unhooked all Am882 drives except one on J2 of the PMDX. Using just one drive to be safe for testing.

(PMDX to Am882)

I have the +5vdc from J2 connected to PUL+ and DiR+ on AM882 (the +5v is jumper end at the driver with a short wire, as instructed by PMDX manual.

Pin 6 on PMDX is Wired to PUL- on Am882 pin 7 is wired to DIR- on Am882

alm and enable are left unhooked.

(Motors to Am882)

4 wire Wanti stepper motors 1090 oz 5.6A 85BYGH450D-008 (red wire=A+ green=A- yellow=B+ blue=B-

hooked to drivers accordingly

72VdC hooked to drives.

drive dip settings are as follows 1 on 2 on 3 off 4 off 5 on 6 on 7 on 8 off

Drives are active and blinking green led no faults.

i am able to move motor fine with Am882 test pulser in the pro tune when hooked up with my laptop.

(PMDX/ Mach settings and hook up)

pmdx is is set to normal mode with charge pump in dip settings.

ess is installed on PMDX with posts plugged in with two ribbon cables supplied by Ess warp 9.

Estop cir is hooked up and functioning properly on port 1 pin 10 Mach

charge pump is enabled in Mach port 1 pin 17

J2 which is showing as axis z in Mach has been enabled port 1 pins 6and 7.

have tried checking both active low on and off and get response from led signals next to pin 6 and 7. Also when I try to Jog the motor I am getting a step light flickering on the PMDX, showing a step signal.

I have tried different motor motor tune settings as well in Mach . The Am882 is set up for micro step 8 in the pro tune screen which they are saying that is equivelant to 1600.

So at this point let me know what else you need

thanks

Ben
