Problems with 2x The Sparklab FTS 2.0 on Duet2 Ethernet....
i am upgrading to 2x Sparklab FTS V2.0 Filament Tracking System, because no Shop in Germany can sell me the Duet magnetic filament system.
The FTS 2.0 has two rolls with an diameter of 8,05mm to move the filament, also i started with 8,05 x 3,14 = 25,277mm at the L-Parameter to calibrate.
the FTS gives an impulse, also i config them with the P-paramter=7
So i mounted the fts 10cm bevor the Bowden extruder and put the simple M591 command in config.g
the calibration at 15mm/s says 25.926mm :
M591 D0 P7 C3 S1 R60:140 L25.926 E100.0 A0
Thats allready ok for zhe first Layer with speed 15 mm/s.
but at other layer speed zb. 60mm/s the print paused with movement to little or movement to max ?????
The calibration worked only for the exat speed setting ???
What is wrong in my setup ?
Please Help..Thanks2020-04-06config.g [link text]([link url]([link url](link url)))

@wummelfrosch You have set your E parameter (minimum extrusion length before a commanded/measured comparison is done) very high at 100mm, so it's likely doing only a couple of measurements on the first layer, then there's a sudden jump as the printer speeds up. Try setting the E much lower, perhaps between 10 and 20mm, and also increase your range R parameter to perhaps 10:200 until the readings settle down and you get some data.
iget with e100 some Data (25,926) and this ar near the correct theoretical data (8,05 x 3,14 = 25,277mm )
it also works for the first layer with a spedd 15 mm/s
the problem is, at the second layer an all other layers the speed is faster than 15mm/s and the printer goes every E-Parameter in into pause mode.
I test it with L25.926 E15.0 again and report it
@wummelfrosch It could be interference as the motors are going faster, at a higher frequency; these sensors are quite susceptible to it. Make sure the wires run away from stepper motor wires, and/or are shielded.
The advice I gave earlier is more on experience with the Duet3D magnetic sensor; I haven't tried with the one you have, so may not be the same.
At the moment i print a small temp tower with slow speed (max 40mm/s
automatic settings)) and already are ok for the moment
I use this settings:
M591 D1 P7 C4 S1 R60:140 L25.926 E15.0 A0
and the console gives me this feedback :
7.4.2020, 18:31:37 M591 D1
Pulse-type filament monitor on endstop input 4, enabled, sensitivity 25.926mm/pulse, allowed movement 60% to 140%, check every 15.0mm, measured sensitivity 25.246mm/pulse, measured minimum 101%, maximum 104% over 757.4mm
later i will trie it with another print and more speed
