I have a new build of the AR3 arm with the AR4 Teensy 4.1, Arduino Nano and external AR3 encoders
When running, I'm able to jog J4 stepper (DM320T Driver), however J1, J2, J3, J5, J6 (DM542T Driver) wont move, but do change in noise pitch when a jog command is sent.
I have checked A+ A-, B+ B- motor pairs at the driver plug for continuity - Check OK
Switched stepper wire pairs, at the driver, also switched +- with in the pairs - No Change
5v / 24v signal switch on the DM542T drivers toggled to both settings - No Change
Drivers are wired with 5v on the PUL+, DIR+. PUL- and DIR- wired to the teensy 4.1
DIR is seeing 5v, PUL has 1.7v and jumps to 1.8v with a jog command.
Driver DIR and PUL are wired with the same 5v + as the teensy 4.1
Is the 5v for the DIR and PUL too high for the teensy 4.1? (but why is J4 working)
24v power supply for the drivers.
12v/5v power supply for the teensy (5v), arduino nano (5v), relay board (12v), step down buck (3.3) for endstops and encoders. Common ground for all 3 voltages.
Should I tie the grounds together for the 24v and 12/5v power supply output voltages? (both wired off the same AC plug)
I have removed the connection between the teensy and the arduino nano, to rule it out - No Change
Endstops and encoders are powered with 3.3v
Cable length from controller to arm base is 2 meters
Driver cable is 18 awg stranded copper
Is the driver cable length too long? (but J4 is working fine)
Driver DIP switch settings checked, difference found between the AR3 and AR4 settings for J6, SW4, both tested - No Change
AR3 ARCS Ver 1.0 (exe), AR4 Version 1.1 (exe) and AR4 Version 1.3 (exe) - AR4 1.3 seems to be the most consistent and best so far.
Encoders are disabled in the AR4 software
EN is setup for the EM stop, when toggled the motors go limp, and firm when released, as expected,
Running windows 7
Any suggestions? as I have run out of things to try and this has got me stumped
Looking at the manuals for the DM542T https://www.omc-stepperonline.com/download/DM542T.pdf
Page 11, ENA signal ahead of DIR at least 5us
Page 10, ENA signal ahead of DIR at least 200ms
Drivers have been tested with both the ENA+- wired and unwired - No Change
Can that change be set or tested in the AR4 1.3 app?
