Have another request. My bed. Has 1kw heater and i use ups for power outages. Is there a way to initiate power failure mode by a switch or 5v? I found 5V out when on battery power so i could connect relay. But how to set it up using an endstop or something else?
Thanks -
You can initiate a pause using an endstop input a a trigger. See the M580 command in the GCode wiki.
-
The M580 is something "select Roland". I don't even know what that is. Was it a typo and should i just look up pause M25 (M24 to resume) in combination with M581 for external trigger?
-
I am sorry, I misremembered - I meant M581. You can use the T1 trigger number to make the printer pause, without having to set up a trigger macro.
-
So if i put: M581 E1 T1 S1 C1 in config.g, it should suffice to execute <pause>and when power is restored, i would execute <resume>macro or it should still be available on print menu on LCD?
Probably i would want to have T2 to execute macro file as i will need to shutdown all the heaters to prevent UPS drain</resume></pause> -
That all sounds good to me, except that you will also need to restore the heater temperatures in your resume macro.

Regarding build plate. I cant seem to find the difference between Mesh grid compensation (G29) and Auto bed compensation (G32)
When i run G29 and add G29 S1 to my starting gcode, nothing happens but when i run G32 just before a print, i can see Z lead screws move tiny bit when printing a model.
On the wiki it says G32 is obsolete, and better to use G29. But what i am missing here. My bed is quiet level at about ~0.09mm (on G32, probing 5 points).EDIT. probably it does the job. Since G29 grid is multiple points adjustments are not that noticeable.
-
BTW is there a tuning procedure for pt100 sensor? I have done tuning for the bed and now its dead on target but hotend is fluctuating up and down 2.5 degrees
-
exactly the same as you would do the bed I did mine last week when I changed my Heater block and Nozzle to the Copper ones.
-

Is it a regular oscillation of 2.5 degrees, or a random fluctuation?
-
If it is a regular oscillation, try increasing the D parameter in the M307 command for the hot end by about 20% (bearing in mind that if you are using a config-override.g file, it's the one in config-override.g that counts).
-
If it is a random fluctuation, you probably have a poor connection in the PT100 wiring.

You can run M122 and look at "Bed compensation in use" to check whether mesh compensation is active.

Thank you. Will check it out

I am having problems with IR probe. Last night set the probe and all was good, today morning started a print and it was 0.55mm off. I ran mesh bed compensation (G29). I have gcode so use saved bed map in my gcode starting script. I noticed this throughout the build that it is not consistent. I do mesh bed compensation probing with heated bed and nozzle.
One thing i have noticed that my IR probe LED sometimes goes very dim and sometimes goes out. Don't know if that has to do with anything.
Just ran test 3 times and i get a lot of play. Here is single point measured:
1. -1.102
2. -1.080
3. -0.595
That is no good at all -
I'm thinking now, perhaps i should run the test before each print?

You probably have a bad crimp connecting in the +3.3V feed to it.
-
Done some testing as per mesh bed compensation wiki description. Set the Z=0 where paper just touches the nozzle.
save Z G92 Z0. then command nozzle up 5 to 100mm and then G30 S-1. I get these on the same spot with heated bed and heated nozzle at my print temps:
2.475
2.477
2.482
2.480
2.517
2.505
2.500
2.507
2.515
So the variation is 42uM. Is that within tolerances? I never print at 0.05 layer hight -
That's a higher variation than normal. Also it seems to be creeping up. What type of Z axis do you have, what is your Z steps/mm, and what probing speed are you using (F parameter in M558)?
-
I have 2 lead screw trapezoidal system, standard prusa style @ Z402.43 steps. My speed is at F800 at the moment but i have bumped it up cause running mesh compensation each time before print. I think it was 600 when tested.
BTW, i checked my IR probe connections and they are good. LED on the probe is out completely. I did not put kapton tape on the back side of IR and my offsets are X5 Y14.5 from the heater block -
Be careful, if you don't have Kapton take on the back of the IR sensor, it could contact the heater block, and if your heater cartridge develops a short too then that will wreck your Duet.
Try a lower probing speed. You may be able to reduce the dive height to speed up probing.
-
Its about 10mm away from heater. Will put some just in case. I have lowered my probing speed to 400. Will test later if it make any difference.
I have a bit of issue trying to set up my starting G code for heater sequence.
I want printer to home, heat up the bed and nozzle at the same time, then home and perform mesh bed compensation.
Something is wrong with my gcode and i ran out of ideas. It heats the bed, then does homing, mesh bed and then heats the nozzle.
Here is my starting gcode:
M83 ; extruder relative mode
M106 P2 S1 ; LED on
G10 ;
M116 H0 ;
M116 H1
G28 W ; home all without mesh bed level
G29 S0 ; mesh bed leveling
G1 Y3 X-7 Z0 F7000.0 ; go outside printing area
M572 D0 S0.07 ; Pressure advance
G1 X100.0 E9 F1000 ; intro line
G1 X204 E12.5 F1000 ; intro lineI tried with M109 and M190
