  • Yes, but what should I do for everyday printing? E.g. in startup GCODE? I do a G28 that homes Y min, X min and the dual Z max (Takes a while) and thats it? I should trust the stored Z? So my Z-probe should not be used for every print? If so I need t…
  • I need some advice. I need to level the two Z axis before doing G32 and G33.  My initial thought are:G28G32 S2G33 But this should only be performed when I have reason to believe its off. How should I do the daily/between prints homing? Maybe G28 and…
  • shaiss said: I do similar in my slicer end code script, or you can add it to Z_PROBE_FINISHED_SCRIPT. I have ENDSTOP_Z_BACK_ON_HOME=0 but still have the nozzle hovering about 1.5mm above the bed, so I still need to tweak that.  Are you using …
  • Are you probing with the same temp on bed as when you print? Inductive sensors will change distance at different ambient temperatures. So z probing should be at same temp always.
  • Ok,  whats the best way to have at least 5 mm space between nozzle and head at all times?  Is it possible to add a G1 Z5 command to the end of G28 in some template? 
  • Is my writing that confusing Yesterday I enabled Z max homing and before that I had only Z probe (as Z min). But I figured what config setting that keeps the nozzle 10mm from bed. I had ENDSTOP_Z_BACK_ON_HOME 10. I set it to 0 and now I'm printing …
  • M119 should always return L for all the switches when none are triggered/pressed. You can test them by running M119 when pressing one by one and see it's state is H. If this is not so they are wrongly configured of faulty.
  • I just enabled Z max endstop. G32 S2 did not go to Z max. But G29 S2 did and it recorded Z height. Recv: Info:Reset Z heightRecv: Printer height:273.37Recv: Info:Autoleveling enabled Doing:G21 ;metric valuesG90 ;absolute positioningG28; Home AxisG1 …
  • I am using latest dev. I do not have Z max homing yet. I actually have mounted hardware for dual Z max but not enabled any of it because I want a fully working printer and need to print one more bracket to get Z max to work reliable. Will Z max hom…
  • I could make a issue in github as this forum is really not made for pasting code and stuff. Bed coating (Z_PROBE_Z_OFFSET) is 0. My Config. Much air? There is almost 10mm between nozzle and bed and I'm unable to get it closer after homing. Except to…
  • As Repetier says. You might need to adjust the current limiting on the TMC2100 as it is not the same as DRV8825. I went from A4988 to TMC2100 and needed to adjust. https://github.com/watterott/SilentStepStick/blob/master/docu/FAQ.md
  • With full steps 20 sounds mathematically reasonable. I have 160 steps on my X with 1/16 microstepping. I would look into microstepping if I were you. What stepper drivers are you using?based on this tutorial: StepsPerTurn = 400 // Most stepper moto…
  • Need to find a better site for posting photos like this Dropbox link: https://www.dropbox.com/s/n27t2exshreosyv/Nozzle-bed-diagram.png?dl=0
  • I think you misunderstand.  When the IR probe triggers the nozzle is 2.16mm from the bed. After homing it raises Z (havent measured how much) but when I start printing and want it to go to Z0 the nozzle is 9.92mm off bed. See my illustration below. …
  • Think I'm going mad. After some back and forwards I am still not there. I just re flashed from current development and did M502 and M500. Did a G32 and Z offset is way off.  I have to babystep -7.76mm before IR probe triggers then I can babystep to …
  • ALWAYS_CHECK_ENDSTOPS 0 seems to have done the trick
  • Ok, I think I got it.  Now I have another issue I might have to report on github. When I Do the G32 S2 it does the 5 x 5 grid autolevel and I can adjust the Z-offset and start printing. I can see Z move while printing to compensate for a skewed bed.…
  • Ok, just to test if I'm getting this. You mention mean plane with autolevel grid. If I get it right and I have a bed that is very straight for all the grid points except on the last sample along the edge it will get a slight diagonal. Difficult to w…
  • Now I finally have Repetier on the BigBox and started doing testing. Having some initial difficulties to getting a perfect Z-offset. You have to distinguish. The leveling with G32 will compensate rotation only based on measured points. To correct fo…
  • Ok, tanks. Will be more trial and error on the design then
  • I'm not wondering what's in eeprom but what's a valid set of grid coordinates for P1, P2 and P3. Should P1 be front (towards me) left corner, P2 front right corner and P3 back left corner?

  • Thanks, There was an option to keep the correction to a certain height and I set it to my total Z height. Now I am a bit confused about the "grid computing regression plane" Bed Measuring Method. I do not get the coordinates to be set for P1, P2 and…

  • Regarding point 5 is to compensate for sag in the rods. If my bed is bumpy I would throw it away   When I do Mesh Bed Leveling on Marlin the nozzle get ~0.15mm closer to the bed in center. This is very repeatable and others with BigBox are seing thi…

  • What do you mean it is not handled by EEPROM? Will not a autolevel be remembered between reboots? If I get you right I would have to do autolevel every time I turn on the printer?
  • How is this coming along? I am concidering converting from Marlin to Repetier on my E3D BigBox. But I have done a mod so I have two Z stepper drivers.  What would really be the icing on the cake is if I could use two Z endstops at Z-max to level and…
