Good news!

Awesome. Thank you!

@kraegar Thank you for recommending, I bought Ultraflexible 60 strands, they are great.

@T3P3Tony can I use my current config for my corexy I use for everything? Thanks for quick replies!

Was it an RJ11 port??? Whoops! Clearly I didn't look at it particularly closely 😆 My bad!!!

Hi, The numbering in the firmware and on the board itself can be confusing. For example there is support for three heaters and two extruders on the Duet itself. The heaters are numbered 0, 1, 2 while the extruders are numbered 0, 1. Heater 0 is the bed heater which means that heater 1, 2 match up with extruders 0, 1. For the expansion connector for the Duex5 the same issue continues. There is support for 5 heaters, 5 extruders and 5 PWM outputs. Continuing from where the Duet left off, the heaters are numbered 3, 4, 5, 6, 7 while the extruders are numbered 2, 3, 4, 5, 6. The PWM outputs on the Deux5 board are numbered 1, 2, 3, 4, 5 but they use the signal lines for heaters 3, 4, 5, 6, 7. To use a PWM output you first need to prevent the needed signal line from being used for a heater. The M307 command takes care of that: M307 H# A-1 C-1 D-1 The # will be the heater number 3, 4, 5, 6, 7 which match up with PWM outputs 1, 2, 3, 4, 5. The M280 command will then control the BLTouch: M280 P# S### The # will be heater number 3, 4, 5, 6, 7 - the same number used in the M307 command. The ### is the "servo position" that the BLTouch responds to for a given operation. For example using 160 will clear an alarm condition in the BLTouch. Frederick

@HBM-3D , have the files you upload been getting bigger?

Many of the failure modes which could cause runaway heating are outside the control of the duet (shorted heater wires, mosfet failed closed, software failure, etc). So it may make sense to have some sort of external safety monitor hooked up to your safety relay. For future development it might make sense to add the ability for a heater fault to switch an IO pin rather than just trying to turn off the heater. This may be possible when the object model / conditional gcode is in place, but I'm not 100% sure.

Thanks, I'll check that out.

@Phaedrux said in Probe Z and SD: Augmenter le micropas sur l'extrudeuse pourrait être bénéfique pour les extrudeuses sans support avec des pas très bas par mm. Normalement, avec une extrudeuse à engrenages et une impression normale avec une buse de 0,4 à une hauteur de couche de 0,2 et une vitesse moyenne, un micropas et une interpolation de 16 est idéal. Thank you for this additional information !

What about the motor currents you set? I believe the max allowed if this is a duet 2 is 2400 yet I see your x, y and z set at 3000. M906 X3000.00 Y3000.00 Z3000.00 E800.00 I30 ; Set motor currents (mA) and motor idle factor in per cent I wonder if that is causing an issue

You need to change the M307 line under Z-Probe and make sure the H value lines up with the heater number you have connected to the bltouch. For example, if you have the bltouch plugged into heater 7, change the line to the following ; Heaters M307 H7 A-1 C-1 D-1 ; disable heater Then you will want to check the following files to make sure they have a consistent heater number in the M280 command as well. /sys/deployprobe.g /sys/retractprobe.g

I have similar configuration to yours (bowden, 24V, 0.9deg, 3:1 gear) and had similar problems of noise. Initially I placed the stepper on suspension which stops the noise but then realized that my max extruder speed was set too high it can handle at most E1500 to E2000. You can read more about it here https://forum.duet3d.com/topic/12049/building-a-diy-public-domain-low-cost-stepper-motor-analyzer/2 Edit: this is the suspended extruder. It prevents the any extruder noise to be amplified by the aluminum frame. The three rubber parts are standard RC parts.

@bearer Yes, it is clear, you are right. Anyway not everyone is an expert programmer, so I think it is legit to kindly ask/suggest for this kind of firmware additions, and this is the main goal of this thread. I hope that someone into Duet/RepRap firmware development will be able to listen to my suggestion, or point me towards some partial actual solution. Thank you!

@dc42 it is firmware version 2.04rc1

If you are trying to use the new RRF3 CAN code on Duet 2, forget it. The SAM4E8E only supports basic CAN, not CAN-FD. There are big differences, in particular CAN supports a maximum of 8 bytes per packet, but CAN-FD supports 64. PS - to get Eclipse to compile files that you added outside of Eclipse, right click on the project in Eclipse and click Refresh.

I see no Linear or Non-linear extrusion correction. Was that checked?

@Phaedrux said in Just completed Auto Tune: Non-resettable. Come in a wide range of set temps. For the bed heater it would be trivial to add. For the hotend you'd likely have to attach to the heatsink due to the temp limit of the devices. So you'd have to do some figuring to decide how hot the heatsink would get in a fault condition. Thanks much. I have not seen that type of device before. Frederick
