@ahoward7652 Firmware Version is 2.04

I have a IFR520 mosfet (n-channel)that I am trying to control with expansion connector Pin 13 (heater 4). on my Duet Wifi I have already disabled it with M307 H4 A-1 C-1 D-1. When I connect the mosfet and power up the Duet Wift the mosfet with a fan connected with no command issued comes on. When I set the I1 param in the M42 command, nothing changes. I can use M42 P4 S255 to turn the fan off. I get the same thing with every other heater pin I try. I assume I am missing something. I thought I had read something that the I1 no longer works with M42? I thought that the heater pins should be active low by default.

I found that my bracket housing was off just a tiny bit. Had to shave a bit of the window back and worked perfectly

@dc42 Ok Thank you I will try that.

Can you give me any direction? I don’t understand the what the values reported mean. I have seen posts referencing report of angle? But I don’t see any of that maybe I am missing something

@dc42 No difference with the PLA. Filastruder told me that if Admin on this forum deems a replacement necessary that they would. I am not sure what else I need to do to get it to at least sense any at all. This is my result during calibration attempt.

I recently have added the Duet Laser Filament Monitor Ver 2.0 to my Duet Wifi(1.04) . Firmware version 2.03beta. When I power up I get the 3 green flashes. When I run a print for calibration my % min and max are zero. I have red flash and green flash but no percentages. Green doesn't appear to flash any more frequent when black ABS filament is being extruded. My custom code in my config.g file is M591 Do P5 C3 R10:300 E3.0 S0. I have checked and rechecked all connections, power. Not sure what I am missing or if I have a defective laser. Not sure of the power but doesn't appear to be very bright/strong. Appears very dim. Printed bracket/enclosure is black abs.

Any one able to help with this?
