No voltage from DB25
I have installed a G540, ESS and mach 3 onto my PC. I have followed the steps here https://warp9td.com/index.php/gettin...epper-and-mach
and I cannot get my motors to move.
They hold when powered and estop seems to be working. I can see my x and y axis change in Mach 3 after resetting the estop but the motors just hold and hummm white noise.
I called Gecko and they had me check the output of pins 3 and 25 on the db25 while jogging the left and right arrows on the keyboard for voltage but I only get .054 volts or nothing, no fluctuations.
Shouldn't the Ethernet smooth stepper test the same way at the db25 port? Because it dosent. I get no voltage on db25 pins 3 and 25 out of the ESS or LPT port when jogging the left and
right arrow in Mach 3.
Also is this motor wired correctly? I haven't put in a resistor "5 amp motor not 3.5amp" but I was told its not necessary to test motor output.

Re: No voltage from DB25
attachment not visible - Invalid Attachment specified. If you followed a valid link, please notify the administrator
while I have not used a Ethernet Smooth Stepper
I would double check the mach 3 smooth stepper plug in is installed
so Mach 3 can use the ESS insread of a PC parallel printer port
and the ethernet connection is working
we need a ESS user to reply

Re: No voltage from DB25
I have the warp 9 plugin installed and it comes up and asks for ESS or printer port. It connects after setting the IP address. I can pull the eathernet cable and I get a
message from mach 3 that the ess is not connected anymore.
I also fixed the attachment.

Re: No voltage from DB25
that's OK
mach3 is obviously communicating with the ESS
on the G540 do you have the charge pump switch enabled or disabled ?
not having the current set resistor on the motor cables 9 pin plug results in the current being set to the maximum 3.5A G540 output
( fitting a 3K5 resistor results in the current being 3.5A when stepping and the current reduction being active when when the axis is inactive )
in mach3 pins and ports
how have you assigned the " printerport" emulated by the ESS
John
as its 23:50 I'll download the Mach 3 and ESS manuals
and continue in the morning

Re: No voltage from DB25
Thanks and yes I have the charge pump off
"in mach3 pins and ports
how have you assigned the " printerport" emulated by the ESS"
I have not done anything in pins and ports regarding the printer port, just set up the motors and estop in there per the ESS instructions. I will post a link in the am....Late for me to now so will check in the am and thanks again.
