@dc42 Thanks, I'm glad I helped find a bug.

@dc42
I figured it out. I have interpolation turned on for X and Y and off for Z. In my config for RRF2 I had interpolation turned on for all. I turned interpolation back on for Z and it sounds fine. I'm not sure why Modix changed it to be off. Is there and advantage to having Z I0 with a belt driven Z axes? It's much smoother and quieter with it on. Strangely it didn't effect the noise on the Z axes at all. They stayed quiet with both settings.

I just updated from reprap 2 to 3.4.0 on a Duet WIFI with a Duex5. Actually I switched from Klipper and did a clean install straight to 3.4.0. Whenever the height map is loaded the X and Y steppers become noisy, the Z are fine. I know the height map effects the Z axes but I can't figure out why the X and Y. It didn't do this in RRF2. Any help would be great. Here's a copy of my config file. Thanks

@dc42 said in Klipper BL Touch Problem:

49: PA15 TIOA1 PWML3 WKUP14 HEATER7 15 HEATER7
Wouldn't this imply PA15 controls the PWM3 plug?

Yes.

So since PA15 actually controls PWM5 and not PWM3 this must mean the pinout table at https://duet3d.dozuki.com/Wiki/Duet_2_Pinout_table is incorrect. Is there a place I can find a correct pinout table or am I just reading it wrong?
Thanks

@dc42 I solved it from one of your earlier post where you said heater 7 was associated with PWM 5. Even though I read that post over and over I thought you had misspoken on the PWM5. Instead I kept referring to the https://duet3d.dozuki.com/Wiki/Duet_2_Pinout_table which had Heater 7 associated with PWML3. I could use some help on how I misread the Duet Pin table. This is line
49: PA15 TIOA1 PWML3 WKUP14 HEATER7 15 HEATER7
Wouldn't this imply PA15 controls the PWM3 plug?
Also with the Duet do I need to activate pullup resistor to avoid floating input?

Thanks, you're amazing.

It's amazing how one can spend days trouble shooting and not try something obvious lol.

For others having this issue my working arrangement is PWM5 which is control pin PA15.

@dc42 I see that he's done it with the Duet 3. The pin assignments would be different. I'm not really sure how the insides of the bltouch work. Seems like even if I had the PWM3 pin assignment wrong that with the white and black wire in the zprobe slots on the Duet that the open and trigger state would change by manually moving the pin. Maybe if I could understand this better it would help trouble shoot. I'll also try to reach out to @Luke-sLaboratory

@phaedrux I'm trying both. I figured I would try here because the Klipper developers aren't familiar with the Duet Wifi pin numbers and setup. The first thing I need to know is the pin id of PWM3 on the Duex. I used this to get my pinout id's https://duet3d.dozuki.com/Wiki/Duet_2_Pinout_table and there's several different pin ids for PWM3. I'm not sure if it makes a difference on which one I use. The ^ in Klipper is to enable the pullup resister and the ! is to invert, I left that out in my original post.

I have the Duet WiFi and Duex5 boards. I've installed Klipper and everything works except the bl touch. The bl touch does its system check moving up and down and I have a solid red light. The debug pin down command doesn't move the pin down. Pushing the pin up or down the probe query shows it as open for both. Everything worked in RepRap2. I have the white wire connected to the z probe and the black to the ground right next to it. I have the servo wires (Brown, Red, Orange) connected to the PWM3 on the Duex5. I've found two examples on line with both using the same pins and claiming it worked. one used sensor_pin: PC1 and !PC3. The other used sensor pin: ^PC1 and control pin: !PA15. I have tried both. I have also tried moving the probe pins to the zstop and using sensor pin: PD29. That also didn't work. I unplugged the white and black wires from the zstop and jumped the two outer pins of the zstop. Did a probe query and got trigger when jumped, so I know the mapping was right. Seems that if I had the PWM3 configured right the probe would go down with the pin down command. Any help would be great, I've been stuck on this for days. I'm going to list the bltouch settings first, under that I will put the whole config list. Maybe there is a conflict somewhere.

I'm using a Mosaic Palette so I need Octoprint. I'm having a problem figuring out the pause gcode. The default just parks it in place. When I try a custom gcode something goes wrong with the extruder where it reverses for a long time and goes way past the 6mm retract. This also happens when I use the Palette load script, it starts loading and reverses. The are several people in the Mosaic forum having the same issue without an answer and their customer support can't figure it out. I think it's confusing absolute retraction and relative. I print in absolute but for trouble shooting I tried changing my config and Cura file for relative and the same thing happens. I know when I had this problem with the Duet and power resume it ended up being a bug in RRF2 that DC fixed. If anyone has a pause script that works in Octo I'd like to start with that.
I have a Duet wifi with the last version of RRF2 on it; the latest version of Octoprint 14.2; Modix Big 60 V3
Thanks

Sorry about taking so long to respond. So I think it may be slipping in the sensor. I've been experimenting with different filaments, they all have the same issue but the slicker ones are worse. What would you recommend doing next?

I guess I don't understand how the sensor works. Is it measuring the total percentage loss from the start of the print to the end or does it measure when movement slows down but resets when it speeds back up? I don't understand how these two lines can read the same measurement but have two different percentage.

8/10/2020, 4:30:51 PM: M591 D0: Duet3D magnetic filament monitor on input 3, enabled, sensitivity 24.50mm/rev, allow 10% to 130%, check every 3.0mm, version 3, mag 130 agc 88, measured sensitivity 24.44mm/rev, min 92% max 104% over 204.8mm
8/10/2020, 4:53:31 PM: M591 D0: Duet3D magnetic filament monitor on input 3, enabled, sensitivity 24.50mm/rev, allow 10% to 130%, check every 3.0mm, version 3, mag 130 agc 88, measured sensitivity 24.44mm/rev, min 60% max 106% over 3796.2mm

The sensor isn't physically mounted but the tube from the sensor fits tightly into the Titan and the tube that feeds the filament is mounted above. I don't see any signs of the tube moving during retraction. My retractions are 2mm and I'm using a .6 nozzle on a volcano. The Titan is a geared so I don't think it's missing steps. My prints are smooth with no signs of over under extrusion.
