New Build and no response from stepper motors

[Ronsut]

Hi
I have just completed an open Build CNC lead screw router and tried the HALweb builder.
I used the generic 3 axis build with ganged Y axis. My board is one by Phill Barrett. See JSON

{"driver":"iMXRT1062","URL":"https://github.com/grblHAL/iMXRT1062","board":"BOARD_T41U5XBB","symbols":["USB_SERIAL_CDC=1","Y_GANGED=1","PROBE_ENABLE=1"],"docker_instance":"","grblHAL":"webBuilder"}

There is no response from any of the four stepper motors!

In the IO GUi settings under stepper (4). I made measurements of the Enable output voltage on the controller board. see below

X,Y,Z boxes left unchecked, resulted in 5v on En after saving and restarting the controller board.
X,Y,Z boxes checked resulted in on En 0v after saving and restarting the controller board. All Good.

However when I monitored the En voltage during jogging there was no change of the EN output voltage. I would have expected Ov on the En output of the T41U5XBB to have flipped to 5V but it stayed at 0V

Same result when i tried a gcode block (G0), relative move. In both cases tested

One of the two tests, I thought should shown some response from the motor, what am I missing.

The BD6600 Modules all seem ok (green led on) 26V to each. En out on T41U5XBB to BD6600 driver Module EN+, EN- is returned to T41U5XBB GND
on each motor.

The limit switches trigger an alarm, the monitor window display is ok and shows status, verbose ok when checked, but there are no axis (XYZ) signals indicated in GUI.

If Step idle delay ($1) is set to 255 or Steppers deenergize ($37) is XYZ (7) then the En outputs are not changing.

The limit switches trigger an alarm, the monitor window display is ok and shows status, verbose ok when checked, but there are no axis (XYZ) signals indicated in GUI.

Status report options ($10) controls which data is output in the real time report, is Pin state checked? Default value is 511.

[Ronsut]

Thanks for prompt reply. I am in Australia, a different time zone.

The Pin state is set to 511, default state.

I have disconnected all but the Y and A axis drivers until I can get the ganged Y/A motors working. Is
that OK

I've tested (with a scope) with your settings and all stepper outputs works as expected. Signal "LEDs" works too - FYI these should not be lit in normal operation. It is odd that inverting the stepper enable signals changes the outputs but motion does not, could be a corrupted hex file? Zip it and post it for me to check.

[Ronsut]

Thanks for your support it is greatly appreciated.
Hope the file helps.

Works for me. Can you measure the enable signal voltages directly on the Teensy pins?
And be aware that A and B axis motors (M3 and M4) has solder bridges that links them to X enable by default...

[Ronsut]

Will measure tomorrow and recheck the soldier bridges.
Getting late here.

[Ronsut]

Results are as follows

Pin 10(STEN) on Teensy4.1 is 3.3 V in jog 0V in Idle (good)

En on Y axis is 4.31V in jog, 0V in idle (??? too low)

En on Y axis but driver disconected shows 5.1V in jog mode 0V in idle. Tested with known good DB6600 drivers modules

There is no pulse out from from BOBoard (in Jog mode) checked with scope. (that concerns me)

I used the same settings that I sent you, now I know they work.

I will put together a new control box with the existing T41U5XBB but make so I can easy swap it out for another T41U5XBB if need be. I will order Monday.

If I get the new box finished later this week I will run the steppers directly from the Teensy on each driver before I install the T41U5XBB. I want to be satified that the Teensy4.1 board is Ok, (it was one I used for my SDR project). I have some level shifters around here somewhere.
I will update the thread.

I ordered the new board from P L Barret and received it yesterday. My CNC leadscrew router is working has I expected. I have removed the two suspect driver chips from the first board and have ordered replacements SMD chips locally.
Thanks for support.
