thanks a lot as this part is small It should print fine even on my badly levelled bed. looking forward to a small scuccess onece again :-)by auser - Ormerod

are there limits to "how far" the automatic bed correction can work? just measured and had one corner roughly 2mm above Z-home! I fear the bed definitely needs replacing. what I don't like most: I could print fine with auto-bed leveling just a few days ago... still wondering what I might have done to incure the warth of the 3d-printing gods :-(by auser - Ormerod

>One disadvantage compared with ultrasonic height sensing is that the nozzle needs to be clean, since any extruded filament stuck on the end will cause premature contact. I think I would like to try HEATING the nozzle and "cleaning" it on the bed. something along the lines of - home x,y - heat nozzle - move to X5 Y5 - lower until "contact" is detected by FSR - move 2-3mm - if FSR shows "less cby auser - Ormerod
Bed leveling with Force Sensing Resistor -> seems to work with simply "touching" the head to the bed. I think this is very intersting. http://reprap.org/wiki/FSRby auser - Ormerod
looking @ x from top it looks like it may be 0.5mm or so curving to the left. other directions look straight. setting the head to e.g. 1mm above te bed and moving the head in increments shows that the bed is slanted along Y (higher @ the motor end) and along X (higher @ the front). but there is no "doming" easily recognizable. What I really don't understand is, why after the G32 procedure the prby auser - Ormerod
>The fully automated bed leveling really does not work properly with the current IR sensor. It actually DID work OK... I probably have to mention that the printer lives in the cellar which is fluoresent-lit. ok off to check the x-rib.

thanks dc42! I Set M208 X230 in my config.g now the bed compensation "does something". but I'm pretty convinced that there is something else worng. - If I do my normal "setup-routine" (Heat everything, Home X, Y, G32) an then move to X100 Y100 the head is closer to 7mm above the bed instead of 5. if i re-set Z with the "paper method" and start printing, I get bottom layers as shown in the picturby auser - Ormerod
> I will check whether my bed calibration points are "outside" maybe this is the reason. will report back. sure enough X only moves to 220 now and my calibration point is at X225. sorry I mot really clear on how M208 is supposed to work. according to the reprap-wiki these are limits for travel in the positive direction. so I would set something like M208 X230 in my config.g.

Indeed I homed Y as well. (I usually do X, Y, G32...).

Do I have to follow a new procedure to get bed-compensation to work with RepRapFirmware-057q-dc42.bin? I'm asking because I just flashed 57q and got a "squeezed" first layer on one corner of the bed and "round filament" in the other corner. checking Z, i realized that it is "standing still" (not compendasting) as usuall. Same with printing "cricle.g". What I do @ startup: get Bed / Head to temby auser - Ormerod

QuoteCash i found out it is not only the the Z-command that will be ignored. It looks like only the last 2 or 3 move commands/lines from the attached file are executed. I had to add more and more lines, that the Ormerod does anything.... I too have the problem that sometimes cura prints start "mid-air". this is using 57l from dc42 (thanks again for the great FW improvements). What I did find oby auser - Ormerod

Did a test, and in general seems to look ok! BUT it did not close the top surfaces (not sure why, could well be some setting I set wrongly).by auser - Ormerod
not sure if it's the same "knocking" but here goes: when z-gears turn "more than just a fraction of a turn" i do sometimes get regular "knocking" sounds. lifting the z-leadscrew and turning the gear a few teeth can make the sound "nearly dissapear"by auser - Ormerod

my ormerod is located in a room whitout windows, the only light is a fluorescent tube, from which the ormerod is shielded (as it sits in a shelf). Still I can not get the combination of z homing and bed compensation to work correctly.
