Creality CR-10 upgrade

Thank you. And its not this path:
M98 P/sys/gantry_leveling.g ? -
It depends on which folder you put the macro in. If you put it in /sys then you should not need to use the full path.

Had a chance to film my first layer.
Using Prusa 5V induction probe on precision aluminium plate.
Cant remember exact deviation on mesh map but its 0.07 max.
I am using gantry leveling as well.
I always get front right quarter of the bed too high. I am lost as dont know why it would not compensate. Those induction probes as per Tom's YT channel are ones of the most acurate ones.
If anyone could chime in and point my error? -
Is there any other metalwork near the front right corner that might be affecting the inductive sensor?
-
There is none. Its uniform. It has y carriage on 4 rail blocks. Bed is 8mm thick on 10mm standoffs from y carriage. Those induction probes are less sensitive to aluminium and my z offset is at ~0.2mm.
I know it should be far better than this.
I have enders with those uneven chinese heated beds running pinda's and they do work very good. Layers are smooth like butter.I have a script where it parks hotend 60mm abobe the bed, blows part cooling fan full whack and heats the bed to print temp, then goes for mesh mapping.

True; but they are much more sensitive to magnetic materials, such as non-stainless steel screws. They are also somewhat sensitive to temperature and supply voltage.
-
There is no fluctuation from psu, unless dwc readouts are inacurate. I have no protruding bolts and all of my fittings are stainless exept for the frame but they are far away.
I know that probes are sensitive to heat and thats why i have a script to move it out of the way while heating.
Here is my bed and whats underneath: -
So i have checked and rechecked and M98 does not work.
My macro file gantry_leveling.g is located in /Macros catalog and i place:
M98 P/macros/gantry_leveling.g
It reports that file is not found. Was this function tested and confirmed working?
Maybe there is syntax errors and rules that must be followed like space between P and path or CAP sensitive? -
M98 is known to work
but it is Case sensistive!did you try
M98 Pgantry_leveling.g? -
Do you have any other characters on that line after the final ".g" ?
Are you certain that when you created the file, you didn't add an extra space after or before the filename?
You can also try:
M98 P"/macros/gantry_leveling.g"
or:
M98 P"gantry_leveling.g"

@dc42 : maybe update the wiki to reflect the fact that quotes are allowed for M98?
-
OK, will try your suggestions. I guess my error will be with Case.
I am sure i have no space after .gBTW, i think i have pinpointed my leveling issue.
I have printed holders for Z motors and my right motor was getting hotter than left one to the point it melted plastic. I have ordered longer motors and some 50x50x5 aluminium angle to fabricate some brackets.
I think it was just turning motor slightly so compensation was canceling out on melted saggy plastic.
Wow, that took me some time to notice. -
@whosrdaddy In addition to knowing quotes are allowed it would be nice to know when they are required.
Maybe I'm old school, but I always contain paths and strings in quotation marks. Especially if there is white space in it.
-
@phaedrux It would be good to have these notes. A lot of useres are beginners as myself and are not familiar with machine code and finding a refference and solution might be overwhelming sometimes.
-
It doesn't explicitly say where they can be used but there is a section covering quoted strings - https://duet3d.dozuki.com/Wiki/GCode#Section_Quoted_strings
-
@tjb1 good find. I knew I'd seen it somewhere. Thanks.
-
Recent versions of RepRapFirmware allow quoted strings to be used anywhere that a string parameter is expected. Some commands (e.g. M587) require the quotes. In older commands (e.g. M32) they are optional, for compatibility with slicers.
-
I changed the text in Quoted Strings and added a note to M98 to reflect this.
-
So i have pinpointed what was missing. Basically i have assumed that macro files are created as *.g but in fact they have none.
I have machined quick angle brackets to replace plastic ones and so far it look good so most probbable cause was melted holder for uneven first layer. -
@agniusm yeah macros can have no extension, or an arbitrary extension.
