@dc42,

Thanks for the advice. I will try increasing the measurement length as you suggest. My sensor is mounted ~20mm above a direct drive extruder and was flexing around a lot. I added a brace which helped a lot but am still having issue. I will try increasing the measurement length as you suggest.

I seem to be having a simmer issue. I installed the mag sensor about a week ago recently purchased from Filastruder as well. It was working okfor a couple of prints then all of a sudden it started overrunning the set parameters of R60:130 L24.8 E3.0. When I swapped out the filament to Ninja Flex ( a very soft TPU) I stated seeing under runs of ~ 30 to 35%. I adjusted the "R" value accordingly and the remainder of the TPU prints finished off ok. I then swapped out my .04 nozzle for a .8mm nozzle with PLA+ and things went south. I'm now seeing under runs down to 10% and over runs up to 330% My last print was like so:

Duet3D rotating magnet filament monitor v2 on input 3, enabled, sensitivity 25.05mm/rev, allow 10% to 370%, check every 3.0mm, current pos 259.8, measured sensitivity 25.27mm/rev, min 94% max 179% over 9348.6mm

I replaced the the cable between the sensor the E1 stop input with a twister trio to cancel out any interference but this did not make any difference.

I'm considering replacing the stock board in my CR10 Pro with a Duet WiFi. I have a Duet in by BLV Cube and love it! I am a little concerned that the CR10 Pro's all metal enclosure will block /effect the wifi reception. I have a spare Duet with with the onboard WiFi module and am hoping not to have to buy one with the external antenna option. It is an all steel case, not alumanum.

Has anyone had luck with full metal enclosures like this?

Veti,

Added E0, did the trick...

Many Thanks!

I'm trying to convert my Duet Wifi to use independent Z drivers so I can auto level the gantry. I followed the instructions here: https://duet3d.dozuki.com/Wiki/Bed_levelling_using_multiple_independent_Z_motors#Section_Example_for_2_motors

When I boot up the board and try to move the Z axis, the side connected to the Z stepper moves faster (farther) than the motor connected to the E1 extruder stepper. I verified this by flipping the motor connections. If I flip the connections the issues moves to the other side so I know it's the board. If I go back to connecting the two motors in series they move in parallel.

I'm running firmware version:2.02(RTOS) (2018-12-24b1). My config looks like so:

; General preferences
G90 ; Send absolute coordinates...
M83 ; ...but relative extruder moves

; Gantry Leveling
M584 X0 Y1 Z2:4 ; two Z motors connected to driver outputs Z and E1
M671 X-20:335 Y0:0 S0.5 ; leadscrews at left and right of X axis

Any advice will be most welcome!
