I swapped the blue wire to GND and black wire to io in and left the brown on 5V EXT. It is working now. Thanks for pointing me in the right direction!!

@OwenD awesome! Thanks, l will try tomorrow.

After replacing PCB managed to get everything up and running. Just need to find settings for Slice Engineering 300c thermistor, the temp reading slightly higher than actual measured with an TC thermometer. It was type 5 in marlin.

@Phaedrux the phase issue is resolved. Found other connection issues. New pcb on order.

@dc42 found connection issues with ribbon cable and pcb, new one on order. Then we move forward.

Just got the extruder motor to work with G1 E1 F100 andG1 E-1 F100. Still no luck with Extrusion Control jogging buttons.

Tried as suggested and received the following error. I have checked phasing by shorting the coils at the connector that attaches to the board and seem fine.

@Phaedrux my apologies, yes the extruder motor did work in the x axis. I will check the led. There was no change in temperature.

Sending T0 initiates the heater and then faults out.
Heater 1 fault: temperature rising too slowly: expected 2.36°C/sec measured -0.00°C/sec

The homing was working just prior to this.
I did test motor by plugging it into the x axis channel "driver 0"

When I try to heat filament I get the following error.
Heater 1 fault: temperature rising too slowly: expected 2.36°C/sec measured -0.00°C/sec

This board is over a year old and has been sitting on the shelf. I have not set any PID values nor have I looked into the heating situation. Thermistors seem to be working. Sometimes looses communication then reconnects. Not sure what else to add. Any help would be appreciated.

Now i am getting the following error.

12/27/2022, 4:46:01 PM G28 X
Error: Failed to enable endstops

@gloomyandy are these values incorrect?
